Step-by-step explanation:
Given:
The ratio of taxes to profits is 7:3.
The taxes and profits total $1000.
Question asked:
Amount of taxes = ?
Solution:
Let ratios = [tex]x[/tex]
And amount of taxes = [tex]7x[/tex]
Then amount of profit = [tex]3x[/tex]
Sum of amount of taxes and profits = $1000.(given)
[tex]= 7x + 3x = 1000\\= 10x = 1000\\[/tex]
by dividing both side by 10
[tex]x = 100[/tex]
Thus, amount of taxes = [tex]7x[/tex] = [tex]7\times100[/tex] = [tex]700[/tex]
Thus, amount of profits [tex]= 3x = 3\times100 = 300[/tex]

The temperature has been going down at a constant rate.In 4 hours it went down 12 degrees.Which expression best shows the temperature change each hour? )
Answer:
t = t₀ - 3n
Step-by-step explanation:
Let t be the temperature and t₀ be the initial temperature of the day
Let n be the number of hours after the initial temperature ( t₀) was registered
Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)
Now, let's write down the expression that shows the temperature change each hour, this way:
t = t₀ - 3n
After 2 hours
t = t₀ - 3 * 2 = t₀ - 6
After 5 hours
t = t₀ - 3 * 5 = t₀ - 15
After 3 hours and 30 minutes
t = t₀ - 3 * 3.5 = t₀ - 10.5

Determine the approximate value of x.
a. 2.045
b.3.264
c.6.736
d.not enough information
Answer:
Option (C) 6.736
Step-by-step explanation:
Please look at the attached modified schematic, where I have constructed a perpendicular line to the base of the triangle.
This creates two Right triangles (i.e. one angle will always be 90°). In doing so, the 80° angle is divided into 30° and 50° angles. In doing so we also then know that on the left Right-triangle the bottom left angle will be 60° since for any Triangle all three angles must add up to 180°.
(Check your self: On the left triangle we have 90° + 30° + 60° = 180° and on the right triangle we have 90° + 50° + 40° = 180°, so we are correct).
Now let us first find the value of side named [tex]y[/tex] on the figure using Right-triangle Trigonometry. In a Right-triangle the longest side is called the hypotenuse (here denoted by the sides [tex]x[/tex] and the one valued [tex]5[/tex]).
So we have:
[tex]sin(60)=\frac{opposite side}{hypotenuse}= \frac{y}{5}\\[/tex]
so solving for [tex]y[/tex] gives:
[tex]sin(60)=\frac{y}{5}\\ y=5sin(60)\\y=\frac{5\sqrt{3} }{2}[/tex]
Similarly for the other triangle we can write:
[tex]sin(40)=\frac{y}{x}\\\\[/tex]
[tex]sin(40)=\frac{\frac{5\sqrt{3} }{2} }{x}\\[/tex]
[tex]x=\frac{\frac{5\sqrt{3} }{2} }{sin(40)}\\\\x=6.736[/tex]
So the correct option is Option (C) 6.736
2. Josh and his brother will drive from Boston
to New York, a distance of 220 miles. If -
they drive an average speed of 50.5 miles
per hour, how long will it take Josh and his
brother to arrive in New York? Round to
the nearest tenth.
Answer: 4.4 hours
Step-by-step explanation:
Distance = 220 miles
Speed = 50.5 miles/hour
speed = distance / time
Therefore :
time = distance / speed
time = 220/50.5
time = 4.356435644
To the nearest tenth , time = 4.4 hours

To make the chocolate shake, Dona added 40 mL of chocolate syrup,
200 mL of milk, and 400 mL of water. How much milk, in liters, would be
required if she uses 450 mL of water?
Answer:
0.225 L of milk, would be required if she uses 450 m L of water.
Step-by-step explanation:
Here, to make the shake, ingredients used by Dina are:
40 m L of chocolate syrup,
200 m L of milk, and 400 m L of water.
So, here Amount of water used = 2 x ( Amount of Milk used) ....... (1)
Now,again the amount of water used by Dona = 450 m L
Let us assume the milk used by her = k m L
⇒ 450 m L = 2 x ( k m L) ( from (1))
or, 450 = 2 k
⇒ k = 450/2 = 225
⇒ k = 225 m L
Also, 1 m L = 0.001 L
So, 225 m L = 225 x 0.001 = 0.225 L
⇒ k = 0.225 L
Hence, 0.225 L of milk, would be required if she uses 450 m L of water.
Dona would need 0.225 liters of milk when using 450 mL of water for her chocolate shake.
To find out how much milk would be required if 450 mL of water is used, we should first look at the ratio of water to milk in the original recipe. Dona used 400 mL of water for 200 mL of milk, which is a 2:1 ratio of water to milk. If she uses 450 mL of water, maintaining the same ratio, we would calculate the amount of milk required as follows:
Determine the proportion of milk to water used originally: 200 mL milk / 400 mL water = 1/2.
Using the proportion, calculate the new amount of milk for 450 mL water: (1/2) * 450 mL = 225 mL.
Convert the milk from milliliters to liters: To do this, we know that 1 liter is equivalent to 1,000 milliliters. Therefore, we divide 225 mL by 1,000 to convert to liters.
225 mL / 1,000 = 0.225 liters of milk is needed.

The solution to the inequality is:
[tex]x>\frac{-1}{2}[/tex]
Solution:
Given inequality is:
[tex]16x-33x<37x+27[/tex]
We have to find the solution to given inequality
[tex]\mathrm{Add\:similar\:elements:}\:16x-33x=-17x[/tex]
[tex]-17x<37x+27[/tex]
[tex]\mathrm{Subtract\:}37x\mathrm{\:from\:both\:sides}[/tex]

[tex]-54x<27[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)}[/tex]
Remember that, change the inequality sign if you divide or multiply both sides by a negative number
If you divide or multiply both sides by a positive number,the inequality sign will not change
[tex]\left(-54x\right)\left(-1\right)>27\left(-1\right)\\\\54x>-27[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}54[/tex]
[tex]\frac{54x}{54}>\frac{-27}{54}\\\\x>-\frac{1}{2}[/tex]
Thus the solution to inequality is found
A vehicle is moving at a constant speed travels 45 miles in 3/4 hour. The driver thinks he will be late to a meeting that is still 65 miles away and that starts in 1.25 hours. Assume he maintains a constant speed. Find the drivers unit rate of speed and explain whether he was late or not
The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed
Step-by-step explanation:
Given
Distance = d = 45 miles
Time = t = 3/4 hour
The unit rate is defined as the distance per unit time. In this case, the unit rate can also be called speed.
So,
[tex]s = \frac{d}{t}\\s = \frac{45}{\frac{3}{4}}\\s = 45 * \frac{4}{3}\\s = 60\ miles\ per\ hour[/tex]
Using this unit rate we can see if the car can travel 65 miles in 1.25 hours or not
Given
Distance = d1 = 65 miles
Speed = s = 60 miles per hour
Putting the values in the formula for speed
[tex]s = \frac{d_1}{t_1}\\60 = \frac{65}{t_1}\\t_1 = \frac{65}{60}\\t_1 = 1.08\ hours[/tex]
As we can see that 1.08 is less than 1.25 so the driver will reach the meeting before time if he drives on a constant speed of 60 miles per hour
Hence,
The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed

c. 3000 - p=16,000
D. 0-3000 = 16,000
Answer:
p - 3000 = 16000
Step-by-step explanation:
none of the options given are correct
The correct equation representing the situation is p - 3000 = 16000, where p is the original price of the car.The correct answer is option D
To determine the correct equation that describes the given situation, we need to understand the relationship between the original price of the car and its discounted price.
Let p represent the original price of the car.
The problem states that the original price was reduced by $3,000, resulting in a discounted price of $16,000.
This relationship can be represented by the equation:
p - 3000 = 16000
Rearranging this equation, we find:
p = 16000 + 3000
Therefore, the best equation that represents the situation is:
p - 3000 = 16000
The correct answer is option D

What is step 10 in this proof?
A.
Statement: line A'E' and line A'E' are concurrent.
Reason: Definition of concurrence
B.
Statement: Point P lies on line C'D'.
Reason: The coordinates of P satisfy the equation of line C'D'.
C.
Statement: All three lines share point P.
Reason: Definition of midpoint
Answer:
10. Statement: Point P lies on line C'D'. Reason: The coordinates of P satisfy the equation of line C'D'.
Step-by-step explanation:
The equation for line C'D' in statement 8 appears to be in error. It should be ...
[tex]y=\dfrac{-s}{2t-r}x+\dfrac{2st}{2t-r}[/tex]
The coordinates of point P given in statement 9 are in error (they cannot be negative). They should be ...
P = (2/3(r+t), 2/3s) . . . . . without the minus signs
This point will satisfy the equation of line C'D'. Here is the algebra. (Notice we have multiplied each term on the right of the above equation by (-1/-1).
[tex]y=\dfrac{s}{r-2t}x-\dfrac{2st}{r-2t}\\\\\dfrac{2}{3}s=\dfrac{s}{r-2t}\cdot\dfrac{2}{3}(r+t)-\dfrac{2st}{r-2t}\qquad\text{substitute P for (x, y)}\\\\s(r-2t)=s(r+t)-3st\qquad\text{multiply by $\frac{3}{2}$(r-2t)}\\\\sr-2st=sr-2st\qquad\text{P satisfies the equation for line C'D'}[/tex]
So, step 10 should say, in effect, P lies on C'D'.

Determine whether the equation has no solution, one solution, or infinitely many solutions. 7(12 – 2 x ) = 4(3 – 3 x )
Answer: The equation has one solution
Step-by-step explanation: First , open the brackets
7( 12 - 2x ) = 4 (3 - 3x )
84 - 14x = 12 - 12x
collect the like terms
84 - 12 = - 12x + 14x
72 = 2x
Therefore divide through by 2
x = 72/2
x = 36
Therefore, the equation has only one solution
Using the graph, determine the value of the slope.
What is the slope?

Daniel bought 2 spoons and 5 forks by using a system of equations and solving for the number of each utensil.
Explanation:The question involves determining how many spoons and forks Daniel bought given that spoons cost $5, forks cost $6, he bought a total of 7 utensils, and spent $40. To solve this, we can use a system of equations where s represents the number of spoons and f represents the number of forks.
The first equation represents the total number of utensils bought:
s + f = 7
The second equation represents the total amount spent:
5s + 6f = 40
To find the values of s and f, we can solve the system of equations. Subtracting the first equation from the second equation (multiplied by 5) gives:
5s + 6f = 40
-(5s + 5f = 35)
------------------
f = 5
Substituting f = 5 into s + f = 7, we get s = 2. Hence, Daniel bought 2 spoons and 5 forks.

A rectangular rug has a perimeter of 220 feet. The width of the rug is two feet less than the length. Find the length and the width.
Answer:
The length is 56 and the width is 54.
Step-by-step explanation:
The perimeter of a rectangle is 2x+2y (width and length on both sides). so 2x+2y=220. Also x=y-2, because the width is 2 feet less than the length. Fill x=y-2 in 2x+2y=220 and we get 2(y-2)+2y=220. 2y-4+2y=220. 4y=216. y=54. Fill in y=54 in 2x+2y=220 and we get 2x+2(54)=220. 2x=220-2(54)=112. x=56.
The length of the rug is 56 feet, and the width is 54 feet.
Explanation:Let's denote the length of the rug as x feet. According to the given information, we know that the width is two feet less than the length, so the width is x-2 feet. The perimeter of a rectangle is the sum of all its sides, which in this case is 2(length + width). Setting up the equation for the perimeter:
2(x + (x-2)) = 220
Simplifying the equation:
2(2x-2) = 220
4x - 4 = 220
4x = 224
x = 56
Therefore, the length of the rug is 56 feet, and the width is 54 feet.

One day you walk 300 meters for 10 minutes. At another day,
you walked at the same speed for 15 minutes. How far did you
walk?
Answer:
450 meters
Step-by-step explanation:
300m=10 minutes
???=15 minutes
300/10=30
15 x 30 =450 meters
To determine the distance walked in 15 minutes, multiply the walking speed (30 meters per minute) by the time (15 minutes), resulting in a total distance of 450 meters walked.
Explanation:The problem we are solving is a basic mathematics question regarding distance, speed, and time. To find out how far you walked on another day at the same speed for 15 minutes, we will use the distance you walked in 10 minutes as a reference.
You walked 300 meters in 10 minutes. This means that in one minute, you walk 300 meters divided by 10 minutes, which is 30 meters per minute. This is your walking speed. To find out how far you walked in 15 minutes, you would multiply your speed by 15.
Therefore, the distance walked in 15 minutes is:
Speed (in m/min) × Time (in minutes) = Distance (in meters)
30 m/min × 15 min = 450 meters.
So, on another day, you walked 450 meters in 15 minutes at the same speed.
What is 44.4% as a fraction
To convert 44.4% to a fraction, express it as 44.4/100, eliminate the decimal by multiplying by 10 to get 444/1000, and then simplify this to 111/250 by dividing both terms by their greatest common divisor.
Explanation:To convert 44.4% into a fraction, start by writing the percent as a fraction with a denominator of 100, which would be 44.4/100. Since there is a decimal in the numerator, we want to eliminate it by multiplying both the numerator and the denominator by 10, transforming it into 444/1000. From here, the fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4. This results in the fraction 111/250, which is the simplest form of the fraction corresponding to the percent 44.4%.
