Don gets $25 for whitewashing a fence. How many fences would he have to whitewash to earn a trip to camp that costs $165.00?

Answers

Answer 1

Answer:

Answer:

7 fences would he have to whitewash to earn a trip to camp that costs $165.00

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per seconds or 4 miles per hour.

As per the statement:

Don gets $25 for whitewashing a fence

⇒ $\text{Unit rate per fence} = \$ 25$

We have to find the fences would he have to whitewash to earn a trip to camp that costs $165.00.

$\text{Number of fences} = \frac{165}{\text{Unit rate per fence}}$

Substitute the given values we have;

$\text{Number of fences} = (165)/(25) = (33)/(5) = 6.6 \approx 7$

therefore, 7 fences would he have to whitewash to earn a trip to camp that costs $165.00

Answer 2

Answer: You would need to divide 165 by 25

25 50 75 100 125 150 175

He would need to whitewash seven fences. Even though 25*7 = 175, its better to have more money then not enough and realistically you cant whitewash a fraction of a fence.

the drama club held tryouts for 6 roles in a one-act play. five people auditioned for lead female, 3 for lead male, 8 for the best friend, 4 for the mother, 2 for the father, and 3 of the humorous aunt. how many different casts can be created from those who auditioned?

Answers

There are 2,880 different casts that can be created from those who auditioned.

To calculate the number of different casts that can be created, we need to multiply the number of options for each role.

For the lead female role, there are 5 options.

For the lead male role, there are 3 options.

For the best friend role, there are 8 options.

For the mother role, there are 4 options.

For the father role, there are 2 options.

For the humorous aunt role, there are 3 options.

To find the total number of possiblecasts, we multiply the number of options for each role:

5 x 3 x 8 x 4 x 2 x 3 = 2,880

Therefore, there are 2,880 different casts that can be created from those who auditioned.

Jarin jogs at a rate of 7.5 miles per hour. How many miles per minute does jarin jog?

Answers

Jarin covered 0.125 miles per minute of jogging

How many minutes make an hour?

The fact that 60 minus makes one hour means that the miles per minute can be determined as the distance covered in one hour divided by the number of numbers in an hour.

In other words, we can first of all, determine the miles covered in one hour as 7.5 miles divided by 1 hour, which gives 7.5 miles, in essence, the miles covered per minute is ascertained by changing the time from hours to minutes.

miles per minute covered by Jog=miles covered in one hour/one hour in minutes

miles covered in one hour=7.5 miles

one hour in minutes=60 min

miles per minute covered by Jog=7.5 miles/60 min

miles per minute covered by Jog=0.125 miles/minute

Jarin covered a mile of 0.125 every minute that he jogged
