Answer:

D)80,000; exponential function

Step-by-step explanation:

We are given that a town with a population of 10,000 doubles every 14 years

So, Initial Population = 10,000

Now we are given that  what will the population be in 42 years

First determine how many times population will double : [tex]\frac{42}{14} = 3[/tex]

So, In 42 years it doubles three times .

Now Linear functions change at a constant rate per unit interval while An exponential function changes by a common ratio over equal intervals.

So, the given situation will be modeled by exponential function

So, Using exponential function : [tex]y=ab^x[/tex]

Where a is Initial Population = 10,000

b is rate of change

x = time = 3 times

So, the population will be in 42 years=[tex]10000 (2)^3[/tex]

                                                             =[tex]80000[/tex]

So, the population will be 80,000 after 42 years.

Thus Option D is correct.

Multiplying by a fraction gives a _____ number.

equal
smaller
larger

Answers

Answer: smaller number.
Examples for understanding:
20×1/2=10
30×1/2=15

Multiplying by a fraction yields a smaller number if the fraction is less than 1, and a larger number if the fraction is greater than 1.

When multiplying by a fraction, the result depends on the fraction you're multiplying by. If the fraction is less than 1 (or what we refer to as a proper fraction where the numerator is less than the denominator), then the result is a smaller number than the original number you started with. For instance, multiplying 5 by 1/2 (which is a proper fraction) will yield 2.5, which is smaller than 5. However, if you multiply by a fraction greater than 1 (an improper fraction where the numerator is greater than the denominator), such as 5/3, the result will be a larger number. So, multiplying 5 by 5/3 will yield approximately 8.33, which is larger than 5.

Tickets for a baseball game cost a? dollars for adults and c? dollars for children. The expression 2a+3c represents the cost (in dollars) for a family to go to the game. What is the cost for the family when an adult ticket is $17? and a child ticket is $12??

Answers


[tex]2(17) + 3(12) = 34 + 36 = 70[/tex]
Final answer:

To find the total cost for the family to attend the baseball game, we substitute the given ticket prices into the expression 2a + 3c, where a is the cost of an adult ticket and c is the cost of a child ticket, resulting in a total cost of $70.

Explanation:

The student is asking about the cost for a family to attend a baseball game with the given prices for adult and child tickets.

Given the cost of an adult ticket as $17 and a child ticket as $12, we use the expression provided (2a + 3c) to calculate the total cost for the family.



Substituting the given values into the expression, we get 2(17) + 3(12), which equals 34 + 36.

Summing up these two products gives us a total of $70.

Therefore, it will cost the family $70 to attend the baseball game.

A biker rode 45 miles in 180 minutes. At what speed (in miles per hour) was the biker travelling? A. 4 B. 17 C. 9 D. 12

Answers

Answer:

v = 15 miles / hour

Step-by-step explanation:

Given:

Distance covered by biker = s=45 miles

time taken by him = t=180 minutes

TO Find:

speed in miles per hour = v = ?

Solution:

As it is given that the distance covered is 45 miles

and time taken by him is 180 minutes

as one hour have 60 minutes

so time taken by rider = t = 180 /60

                                          = 3 hours

this step is done because we have to find speed in miles per hour

Now

The formula for finding the distance is

distance = speed * time

or

s = v * t

we have to find v

so dividing both sides by t

[tex]\frac{s}{t} = \frac{v*t}{t}[/tex]

it becomes

[tex]v = \frac{s}{t}[/tex]

Putting the values

[tex]v = \frac{45}{3}[/tex]

solving it gives

v = 15 miles / hour

which is the required speed

in the given options it is not available


The speed is 15 miles per hour, not matching any of the provided answer choices.

The question asks for the speed of the biker in miles per hour when given the distance rode over a certain amount of time. To find the speed, we can use the formula: Speed = Distance / Time.

In this case, the biker rode 45 miles in 180 minutes. Since there are 60 minutes in an hour, we first convert 180 minutes into hours by dividing by 60: 180 / 60 = 3 hours.

Next, we calculate the speed: Speed = 45 miles \/ 3 hours = 15 miles per hour. But since this isn't one of the options provided, it seems there has been a typo in the answer choices. The correct answer, which should be 15 mph, is missing in the options.

If a solid piece of an aluminium cylindrical rod has a volume of 200 cm3 and a base area of 20 cm2, what is the length of the piece of aluminium rod?

Answers

Answer: 10 cm

Step-by-step explanation:

Given: The volume of a solid piece of an aluminium cylindrical rod =[tex]200\cm^3[/tex]

The base area of cylinder = [tex]20\ cm^2[tex]

We know that the volume of cylinder is given by :-

[tex]\text{Volume]=\text{base area}\times \text{height}\\\\\Rightarrow200\=20\\times h\\\\\Rightarrow\ h=\frac{200}{20}=10[/tex]

 

Hence, the length of the piece of aluminium rod = 10 cm

To find the length of the aluminum rod with a volume of 200 cm³ and a base area of 20 cm², divide the volume by the base area. The length is 10 cm.

If a solid piece of an aluminum cylindrical rod has a volume of 200 cm3 and a base area of 20 cm2, to find the length of the aluminum rod, we can use the formula for the volume of a cylinder, which is Volume = Base Area  imes Height (or length in this case, since it's a rod). Given the volume (V) is 200 cm³ and base area (A) is 20 cm², the length (L) can be calculated as L = V / A.

When you divide 200 cm³ by 20 cm², the result is:

L = 200 cm³ / 20 cm² = 10 cm.

Therefore, the length of the aluminum rod is 10 cm.

Answers

Answer:

Saul is incorrect. The proper answer should be 6x^3

Step-by-step explanation:

Think of "x^3" as "x". So we have 2x+4x = 6x. Similarly, 2x^3+4x^3 = 6x^3. The exponents of the like terms do not change.

As a more real world example, let's say that we replace "x^3" with "dogs". Saying "2x^3" could mean "2 dogs". Same goes for "4x^3" meaning "4 dogs". So "2x^3+4x^3" turns into "2 dogs + 4 dogs", and you can see that leading to 6 dogs total. The last step is to replace "dogs" with "x^3" to end up with 6x^3. The x^3 stays the same the whole time in much the same way that "dogs" do not change either.

Ben and Jerry’s ice cream company estimates that for every 32 people that they serve their delicious ice cream to, they need to make 128 ounces of ice cream. How many people can they serve if they make 704 ounces of ice cream?

Set up a proportion and solve.

Answers

The first part of the proportion would be the known values of 32 people to 128 ounces.

The second part of the proportion is X ( the number of people) for 704 ounces.


This is written as 32/128 = X/704


To solve for X Cross multiply:

32 * 704 = 128x

Simplify:

22528 = 128x

Solve for X by dividing both sides by 128:

x = 22528 / 128

x = 176 people

Use the figure below list the sides least to greatest of triangle PRQ.

Answers

Answer:

Hence third choice RQ, RP, PQ is correct.

Step-by-step explanation:

We know that if A, B, C are the angles of the triangle and if ∠A > ∠B

a>b   {Where “a” is side created by angle A and “b” is side created by angle B }.

We will use same property to decide which side is bigger.

In triangle PRQ,

∠P = 30 degree

∠R = 85 degree

then ∠P + ∠R + ∠Q = 180 {since sum of all three angle of triangle is 180 degree}

30 + 85 + ∠Q = 180

115 + ∠Q = 180

∠Q = 180 - 115

∠Q = 65

Now we know measure of all angles so we can do comparison using above property.

Smallest angle is ∠P so side RQ will be smallest.

Largest angle is ∠R so side PQ will be largest.

Hence we get RQ < RP < PQ.

Hence third choice RQ, RP, PQ is correct.

Answer:

7.11 and 9.48

Step-by-step explanation:

.12 is equal to 7.11

with out coupon


.12 is equal to 9.48

with the coupon


a. Isaac's total bill is $84.53

b. Isaac's price after the discount is $63.40

c. The shoe store clerk's commission before the coupon is $9.48 and $7.11  after the coupon

Solution to the first question

Total bill = cost of shoes + tax paid

Tax paid = tax rate + cost of shoes

Cost of shoes = $37.00 + $42.00. = $79

Tax paid = $79 + 0.07 = $5.53

Total bill = $5.53 + $79 = $84.53

Solution to the second question

The discounted price of the shoes can be found by subtracting the value of the discount from the price of the shoes

Discounted price = cost of the shoes = value of the 25% discount

Value of the 5% discount = 0.25 x $79= $19.75

Discounted price = $79 - $19.75 = 59.25

Bill = discounted price x ( 1 + tax rate)

59.25 x 1.07 = $63.40

Solution to the third question

Commission before the coupon

Commission = 12% x price before the coupon

0.12 x $79 = $9.48

Commission after the coupon

Commission = 12% x price after the coupon

0.12 x 59.25 = $7.11

A candy bar has 220 calories 132 calories are sugar what percent of the calories does the candy bar have?

Answers

What are the answer choices?



To find out what percent of the calories in a candy bar comes from sugar, divide the calories from sugar (132) by the total calories (220) and multiply by 100, resulting in 60% of the calories being from sugar.

To calculate what percent of the calories in the candy bar are from sugar, we can use the formula for percentage: (part / whole) x100. In this case, the part is the number of calories from sugar, and the whole is the total number of calories in the candy bar.
First, let's identify the given values:

Total calories in the candy bar = 220 CaloriesCalories from sugar = 132 Calories

Now, let's calculate the percentage:

Percentage of calories from sugar = (132 / 220) x 100

Calculating this, we find:

Percentage of calories from sugar = 0.6 x100Percentage of calories from sugar = 60%

Therefore, 60% of the calories in the candy bar are from sugar.

The sum of two numbers is 46 and the difference is 10 . What are the numbers?

Answers

Answer: 28 and 18


Step-by-step explanation:

I used the guess and test strategy to find that:

28 - 10 = 18

28 + 18 = 46

Final answer:

To find the two numbers, we need to solve a system of equations. By assigning variables to the numbers and setting up equations based on the given information, we can use the method of substitution to find the values of x and y. The two numbers are 28 and 18.

Explanation:

To solve this problem, let's assign variables to the numbers. Let's say the two numbers are x and y. We are given two pieces of information: the sum of the two numbers is 46, so we can write the equation x + y = 46, and the difference between the two numbers is 10, so we can write the equation x - y = 10.

To solve this system of equations, we can use the method of substitution. Rearrange one of the equations to solve for one variable in terms of the other. For example, we can rearrange the first equation to get x = 46 - y. Substitute this expression for x in the second equation:

(46 - y) - y = 10.

Simplify the equation:

46 - 2y = 10. Subtract 46 from both sides:

-2y = -36. Divide both sides by -2 to solve for y:

y = 18. Substitute this value of y back into one of the equations to solve for x:

x + 18 = 46. Subtract 18 from both sides:

x = 28.

So the two numbers are 28 and 18.

We have two linear functions which intersect at a point. Linear functions are lines which are made of points that satisfy the function or relationship.  This means at the intersection, this point (3,-1), both functions have values. An input of x=3 produces y=-1 in both functions.


Answer:

The correct option is 4.

Step-by-step explanation:

If the graph of a function represent in coordinate plane, then x-axis represents the domain of the function and y-axis represents the range of the function.

We have to find the input value that produces the same output value for the two functions on the graph.

From the given graph it is clear that the intersection point of both functions is at (3,-1).

At x=3 the output value of f(x) is -1.

At x=3 the output value of g(x) is -1.

It means both functions have same output -1 at x=3.

What is the area of the rhombus shown below?

Answers

Answer:

B

Step-by-step explanation:

The interior of the 4 triangles in the rhombus are right angle triangles. In addition AC is bisected by BD and BD is bisected by AC. Those form the sides of the right angle triangle.

So the sides of the right angle are

1/2 17 = 8.5  and1/2 15 = 7.5

The area of one right angle is

1/2 * 8.5 * 7.5 = 1/2 * 63.75 = 31.875But there are 4 of themArea of the rhombus = 4 * 31.875 = 127.5

The answer is B

Answer:

B. 125.5 square units

Step-by-step explanation:

The area of a rhombus is half the product of the diagonals.

If the diagonals have lengths a and b, then the are is:

area = ab/2

area = (17)(15)/2

area = 255/2

area = 127.5

Answer: B. 125.5 square units

Solve f/a+r=m/s for m

Answers

Answer:

d.  m = fs/ (a+r)

Step-by-step explanation:

f/ (a+r) = m/s

We want to isolate m, so we will multiply both sides by s

f/ (a+r)  *s= m/s*s

fs/ (a+r) = m

[tex]\dfrac{m}{s}=\dfrac{f}{a+r}\qquad\text{multiply both sides by}\ s\neq0\\\\\boxed{m=\dfrac{fs}{a+r}}[/tex]
