Answers

Answer 1

Answer: The volume of a cylinder is Pi times the radius^2 times the height

Volume = Pi x 6^2 x 2
Volume = 226.2

a ferris wheel can accommodate 55 people in 15 minutes. how many people could ride the ferris wheel in 6 hours? what was that rate per hour

Answers

15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour.
Then, multiply the number of people per hour by the 6 hours:
6 hours x 220 people =1320 people in 6 hours.

55 per 15 x4 60x 6= 6 hours
55 times 4 times 6 and 1,320 rode on it

Kara buys 24 bagels. Ten are whole wheat. What fraction of the bagels are wheat? Write in simplest form.

Answers

since 10 is whole wheat, the fraction is 10/24
in the simplest form 5/12

First the default fracton: 24 over 10 bagels.
So 24 over ten simplified (made into smallest form) 12 over 5.

Your answer is 12

The table below shows the outputs y for different inputs x:Input
(x) 1 1 3 3
Output
(y) 4 2 12 6

Part A: Does the table represent y as a function of x? Justify your answer. (5 points)

Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below:

f(x) = 20 + 10x

What is the value of f(120), and what does f(120) represent? (5 points

Answers

Answer with explanation:

Part A:

A relation is said to be a function where each input has only a single output.

We usually take the input variable as 'x' and the output variable as 'y'.

In the given table, we can see that 1 is the input value corresponding to 4 and 2 both.

i.e. one input value corresponds to two different output values that contradicts the definition of the function.

Thus the given table doesn't represent any function.

Part B: Given : The total cost f(x), in dollars, for renting a paddle-boat for x hours is shown below:

$f(x) = 20 + 10x$

At x= 120 , $f(120) = 20 + 10(120)=20+1200=1220$

It represents that the total cost for renting a paddle-boat for 120 hours is $1220.

Part A)
The table doesn't represent y as a function of x.
Why? One reason is that 1 or 3 is the first element in more than one ordered pair.
Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220
f(120) represents cost of boating for 120 hours.
