Step-by-step explanation:
TTM/Imagine Math.
The correct answer is:
C. Raise the number of days to the third power and then multiply this value by 2.
Sure, here's a step-by-step solution:
1. Initial Number of Infected People: Start with the initial number of infected people, which is 2 in this case.
2. Exponential Growth Model: Use the exponential growth model to represent the increase in the number of infected people each day. The model is given by the formula [tex]\(I = a \cdot 3^D\)[/tex], where:
- [tex]\(I\)[/tex] is the number of infected people,
- [tex]\(a\)[/tex] is the initial number of infected people (which is 2),
- [tex]\(3\)[/tex] represents the tripling effect each day, and
- [tex]\(D\)[/tex] is the number of days that have passed.
3. Raise 3 to the Power of Number of Days: Raise 3 to the power of the number of days that have passed. This accounts for the tripling effect each day.
4. Multiply by Initial Number of Infected People: Multiply the result from step 3 by the initial number of infected people (which is 2). This gives the total number of infected people after the given number of days.
So, to determine the number of infected people from the number of days that have passed, raise 3 to the power of the number of days and then multiply this value by 2. Therefore, option C is the correct answer.
The correct question is:
Two people become infected with a virus that spreads quickly. Each day that passes, the number of infected people triples. How can the number of infected people be determined from the number of days that have passed?
A. Raise 3 to the number of days and then multiply this value by 2 .
B. Add the number of days to 2 and then multiply this sum by 3.
C. Raise the number of days to the third power and then multiply this value by 2 .
D. Multiply the number of days by 3 and then add 2 to this product.

Yesterday, Carmen went on a bike ride. Her average speed was 8
miles per hour. Today, she went on another ride, this time averaging 13
miles per hour. In the two days, she biked for a combined total time of 9
hours.
Let x
be the number of hours she biked yesterday. Write an expression for the combined total number of miles she biked in the two days.
Answer:
Step-by-step explanation:
Yesterday, her rate was 8mph, her time was x hours.
Today, her rate was 13mph, her time was 13 - x hours.
So the total distance she biked on the two days is
d = 8x + 13(13 - x), or 169 - 5x
Answer:
[tex]8x+13(9-x)[/tex] or [tex]-5x+117[/tex] miles.
Step-by-step explanation:
Let x represent number of hours Carmen biked yesterday.
[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]
We have been given that yesterday Carmen's average speed was 8
miles per hour. So distance covered in x hours would be [tex]8x[/tex].
We are also told that Carmen biked for a combined total time of 9
hours. So the number of hours biked second day would be [tex]9-x[/tex]. The distance covered in [tex]9-x[/tex] at a speed of 13 miles per hour would be [tex]13(9-x)[/tex].
Total distance covered by Carmen would be: [tex]8x+13(9-x)[/tex]
[tex]8x+117-13x[/tex]
[tex]8x-13x+117[/tex]
[tex]-5x+117[/tex]
Therefore, the total distance covered by Carmen in the two days would be [tex]-5x+117[/tex] miles.

3 quarters of the batch of 20 cookies burned when you forgot to take them out of the oven how many cookies burned
Answer:
15 cookies
Step-by-step explanation:
We have 20 cookies and we know that three quarters of them were burned. To find the number of cookies burned, divide the 20 cookies into 4 equal parts.
This will give you 4 parts of 5 cookies.
[5] + [5] + [5] + [5]
Then they tell us that 3 quarters were burned. This means that of these 4 parts [5] + [5] + [5] + [5], 3 were burned. Then take 3 of these parts and add them.
[5] + [5] + [5] = 15 cookies.

A wall clock has a circumference of 43.96 inches. What is the area of the clock?
find the radius:
r = C/2pi
r= about 7 (6.99645)
find the area:
A = pi(r)^2
A = about 153.78194 inches^2
Answer: The area of the circle in inches is A= 153.64 inches²
Step-by-step explanation:
This problem bothers on the calculations on shapes
In this Case a circle
The circumference of a circle is given by
C=2πr
Given that C =43.96 inches
We need to solve for the radius, because we also need the radius to solve for the area
43.96= 2*3.142*r
43.96=6.284r
r= 43.96/6.284
r=6.99 inches
Now back to the area of a circle which is given by
A=πr²
Substituting our value for Pi we have
A= 3.142*6.99²
A=3.142*48.89
A= 153.64 inches²

How many equations in the same variables must be in a set to solve a system of linear equations?
Answer:
For a unique solution, there must be as many consistent, independent equations as there are variables.
Step-by-step explanation:
Each equation lets you write an expression for one variable in terms of the others in that equation. That expression can be substituted throughout the system, reducing the number of equations and variables by one each.
After n-1 such substitutions in a system of n equations, there will be one equation left. If that is an equation in one variable, then the solution to the system can be easily found. If more than one variable remains (> n variables in n equations), then the system cannot be solved for definitive values of each of the variables.
___
If the equations are inconsistent, there is no solution. If the equations are dependent, then there is no unique solution.
To solve a system of linear equations, one generally requires the same number of equations as there are variables for a unique solution, otherwise the system may have either an infinite number of solutions or none.
To solve a system of linear equations, you generally need as many equations as there are variables. If you have two variables, you should have two linear equations to find a unique solution. For example, the equations 3x - 2y = 24 and 3x + 9y = 30 form a system that can be solved because there are two equations with two variables (x and y).
If there are more variables than equations, then you may either have infinitely many solutions or no solution, depending on the equations' consistency. If you have fewer equations than variables, as in the case of three variables with only two equations, you typically have an undetermined system where you can choose one variable as a parameter and express the others in terms of it, leading to an infinite number of solutions.
For homogeneous equations where the vector b is zero (Ax = 0), the solutions form a subspace of the vector space, and nontrivial solutions exist if the system is not of full rank.
Convert the angle 0=14pi/9 radians to degree
Answer:
280 degrees.
Step-by-step explanation:
To convert radians to degrees we multiply by 180/pi:
angle O = 14pi/ 9 * 180 / pi
= 14*180 / 9
= 280 degrees.
The angle 0=14pi/9 radians can be converted to degrees by using the conversion factor 1 radian = 57.3°. Multiplying the given angle in radians by the conversion factor results in an equivalent angle of 280° in degrees.
Explanation:To convert the angle from radians to degrees, we use the conversion factor 1 rad = 57.3°. The problem provides the angle 0 = 14pi/9 radians. By using the conversion factor, the process of conversion would be as follows:
Multiply the value in radians by the conversion factor. So, 0 in degrees = 14pi/9 * 180°/pi = 280°
Therefore, the angle 0=14pi/9 radians is equal to 280° in degrees.

An online music club has a one-time registration fee of $20 and charges $0.50 for each song download. If Ella has $50.00 to join the club and buy songs, which inequality gives the maximum number of songs, s, she can buy?
Answer:
D.
Step-by-step explanation:
50-20=30 (because of the initial cost)
Then multiply 30*0.5=60
so she can buy less than or equal to 60
Answer:
D. S ≤ 60
Step-by-step explanation:
Ella has $50.00 and the registration fee is $20. This means that she would have $30.00 to buy songs and each song costs $0.50, so:
$30.00/$0.50= 60
The number of songs that she would be able to buy is 60.
According to this, the inequality that gives the maximum number of songs that she can buy is S ≤ 60 as it indicates that the maximum number of songs (s) that she can buy is less than or equal to 60.

Answer:
264 cubic meters
Step-by-step explanation:
The sea turtle habitat at the zoo has a total volume of 264 cubic meters.
To find the total volume of the sea turtle habitat, which consists of two connected aquariums, you can calculate the volume of each aquarium separately and then add them together.
For the first aquarium:
- Length = 6 meters
- Width = 4 meters
- Height = 2 meters
The volume of the first aquarium is calculated as:
Volume_1 = Length * Width * Height
Volume_1 = 6 m * 4 m * 2 m
Volume_1 = 48 cubic meters
For the second aquarium:
- Length = 8 meters
- Width = 9 meters
- Height = 3 meters
The volume of the second aquarium is calculated as:
Volume_2 = Length * Width * Height
Volume_2 = 8 m * 9 m * 3 m
Volume_2 = 216 cubic meters
Now, to find the total volume of the sea turtle habitat, you add the volumes of the two aquariums together:
Total Volume = Volume_1 + Volume_2
Total Volume = 48 cubic meters + 216 cubic meters
Total Volume = 264 cubic meters
So, the total volume of the sea turtle habitat at the zoo is indeed 264 cubic meters, as provided.

Destructimous has 7 sonic blasts and 13 heat rays. It also has a 2/7 chance of using its ultra power blast. Luckily, Octagon’s sheild reflected that blast and stopped all the robots. How many ultra power bots did Destructimous have? Pls show/ explain your work. (i know the answer i just dont know how to find it).
Destructimous had 6 ultra power blasts.
The total number of blasts Destructimous has is:
Total blasts = Sonic blasts + Heat rays
Total blasts = 7 + 13
Total blasts = 20
Now, we know that Destructimous has a 2/7 chance of using its ultra power blast. To find out how many ultra power blasts it fires, we calculate 2/7 of the total blasts:
Ultra power blasts = (2/7) * Total blasts
Ultra power blasts = (2/7) * 20
Ultra power blasts = 40/7
Now, since we can't have a fraction of a blast, we need to round this number to the nearest whole number. In this case, 40/7 is approximately 5.71, so when rounded, it's 6.
So, Destructimous had 6 ultra power blasts.

if the probability of p(m and n) =0.2 p(m)=0.4 and m and independent events, what is p(n)?
Answer:
P(n) = 0.5
Step-by-step explanation:
For two events which are independent, we use the multiplication rule which states P (A and B) = P(A) * P(B). Substitute P(m) = 0.4 and P(m and n) = 0.2 into this formula.
P (m and n) = P(m) * P(n)
0.2 = 0.4*P(n)
Divide by 0.4 on both sides.
0.2 / 0.4 = P(n)
0.5 = P(n)

Compute all values of x such that x-1 is the reciprocal of x+1. Express your answer in simplified radical form.
Answer:
x = ±√2
Step-by-step explanation:
x - 1 = 1/(x + 1)
(x -1)(x + 1) = 1 Multiplied each side by x + 1
x² - 1 = 1 Difference of two squares
x² = 2 Add 1 to each side
x = ±√2
x-1 is the reciprocal of x+1 when x = -√2 or x = √2.
Check:
(a) x = -√2
-√2 - 1 = 1/(-√2 + 1)
-(√2 + 1) = (√2 +1)/[(-√2 +1)(√2 + 1)]
-(√2 + 1) = (√2 +1)/(-2 +1)
-(√2 + 1) = (√2 +1)/(-1)
-(√2 + 1) = -(√2 +1)
(b) x = √2
√2 - 1 = 1/(√2 + 1
√2 - 1 = (√2 - 1)/[(√2 + 1)(√2 - 1) ]
√2 - 1 = (√2 - 1)/(2 - 1)
√2 - 1 = (√2 - 1)/1
√2 - 1 = √2 - 1
OK.

Experimenting, you have found that 12 ounces of 180°F coffee in your favorite cup will take 20 minutes to cool to a drinking temperature of 110°F in a 70°F room. Assume that when you add cream to the coffee, the two liquids are mixed instantly, and the temperature of the mixture instantly becomes the weighted average of the temperature of the coffee and of the cream (weighted by the number of ounces of each fluid). Also assume that the cooling constant of the liquid (the constant k in the equations on p. 237 in section 3.8 for Newton's Law of Cooling) does not change when you add the cream. (a) If you add 2 ounces of 40°F cream to the 180°F coffee in the cup, how long will it take for the mixture to reach drinking temperature? Give your answer (in minutes) in decimal form with at least 3 decimal digits (for example, 12.345 minutes).
Answer:
16.033 min
Step-by-step explanation:
We can write Newton's Law of Cooling as
T = Tₐ + (T₀ - Tₐ)e^(-kt), where
Tₐ = ambient temperature of the surroundings
T₀ = initial temperature of the object
k = the cooling constant
t = the time
(1) Calculate the cooling constant
Data:
T = 110 °F
T₀ = 180 °F
Tₐ = 70 °F
t = 20 min
Calculation:
110 = 70 + (180 - 70)e^(-k×20)
40 = 110e^(-20k)
0.363 64 = e^(-20k)
-1.0116 = -20k
k = 0.050 580 min⁻¹
(2)After adding cream
(a) Calculate T₀
2 oz × 40 °F + 12 oz × 180 °F = 14 oz × T₀
80 °F + 2160°F = 14T₀
2240 °F = 14T₀
T₀ = 160 °F
(b) Calculate the time to cool to drinking temperature
110 = 70 + (160 - 70)e^(-0.050 580t)
40 = 90e^(-0.050 580t)
0.444 44 = e^(-0.050 580t)
-0.810 93 = -0.050580t
t = 16.033 min
It will take 16.033 min for the mixture to reach drinking temperature
To determine the time it takes for the mixture to reach drinking temperature, we first calculate the initial temperature of the mixture after adding 2 ounces of 40°F cream to the 180°F coffee, which turns out to be 165°F. Then, according to Newton's Law of Cooling, the time it takes for the mixture to decrease from 165°F to the drinking temperature of 110°F would be the same as the time it took for the original coffee to cool from 235°F to 180°F, given the cooling constant doesn't change when we add the cream. Therefore, the mixture will take approximately 20 minutes to reach drinking temperature.
Explanation:To determine the time it takes for the mixture to reach drinking temperature, we first need to calculate the initial temperature of the mixture. When you add 2 ounces of 40°F cream to the 180°F coffee, the temperature of the mixture instantly becomes the weighted average of the temperature of the coffee and of the cream. Thus, we have:
(12 * 180 + 2 * 40) / (12 + 2) = 165°F.
Now we need to calculate the time it takes for the mixture to decrease from 165°F to the drinking temperature of 110°F. According to Newton's Law of Cooling, the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature. If we assume that the proportionality constant (or the cooling constant) doesn't change when we add the cream, then the time it takes for the mixture to cool from 165°F to 110°F will be the same as the time it took for the original coffee to cool from 235°F (165 + 70) to 180°F (110 + 70), which is 20 minutes. We can conclude that the mixture will take approximately 20 minutes to reach drinking temperature.

Living with parents: The Pew Research Center reported that 36% of American Millennials (adults ages 18–31) still live at home with their parents. A group of students wants to conduct a study to determine whether this result is true for students at their campus. They survey 300 randomly selected students at their campus and determine that 43% of them live at home with their parents. With this data, they test the following hypotheses. H0: Of Millennial students at their campus, 36% live at home with their parents. Ha: More than 36% of Millennial students at their campus live at home with their parents. In order to assess the evidence, which question best describes what we need to determine? If we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 36%? If we examine a sample of students at their campus and determine the proportion who still live at home with their parents, how likely is that proportion to be 43% or more? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 36%? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%? If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be 43%?
To assess the evidence of Hypothesis testing, the students need to determine the likelihood of the proportion of Millennial students at their campus that live at home with their parents being 36% or higher.
Explanation:The question here is regarding the testing of a population proportion using statistical hypothesis testing, specifically a one-sample z-test. The null hypothesis (H0) is that the population proportion is equal to a specified value, in this case, 36%). The alternative hypothesis (Ha) is that the population proportion is greater than the specified value (more than 36%).
The question we need to answer is 'If we examine the proportion of students at their campus who still live at home with their parents, how likely is that proportion to be more than 36%?'
The scenario suggests an indication towards a right-tailed z-test as we're looking to see if the data indicates a proportion >36%. However, as with all statistical tests, one should be cautious about drawing definitive conclusions without additional context and understanding the potential for sampling variability and error.

14348907, ..., 9, 3, 1
17
15
16
18
Answer:
There are 16 terms in the sequence.
Step-by-step explanation:
The given sequence is
14348907, ..., 9, 3, 1
The first term of the sequence is
[tex]a_1=14348907[/tex]
The last term of the sequence is [tex]l=1[/tex]
The common ratio is [tex]r=\frac{1}{3}[/tex]
The nth term of this sequence is;
[tex]a_n=a_1(r)^{n-1}[/tex]
We plug in the common ratio and the first term to get;
[tex]a_n=14348907(\frac{1}{3})^{n-1}[/tex]
The find the number of terms in the sequence , we plug in the last term of the sequence.
This implies that;
[tex]1=14348907(\frac{1}{3})^{n-1}[/tex]
[tex]\frac{1}{14348907}=(\frac{1}{3})^{n-1}[/tex]
[tex]\Rightarrow 3^{-15}=3^{-(n-1)}[/tex]
Since the bases are the same, we equate the exponents;
[tex]-15=-(n-1)[/tex]
[tex]15=n-1[/tex]
[tex]15+1=n[/tex]
[tex]n=16[/tex]
2/3x - 2 = 7 need help please I aint that good at math
Answer:
[tex]\large\boxed{x=\dfrac{27}{2}\to x=13\dfrac{1}{2}\to x=13.5}[/tex]
Step-by-step explanation:
[tex]\dfrac{2}{3}x-2=7\qquad\text{add 2 to both sides}\\\\\dfrac{2}{3}x-2+2=7+2\\\\\dfrac{2}{3}x=9\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x=3\cdot9\\\\2x=27\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}=\dfrac{27}{2}\\\\x=\dfrac{27}{2}\to x=13\dfrac{1}{2}\to x=13.5[/tex]
