plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?

Answers

Answer:

[tex]Fence = 41.408ft[/tex]

Step-by-step explanation:

Given

[tex]d = 24ft[/tex]

Required

Determine the length of the wall

First, we calculate the circumference (C) of the semi-circle

[tex]C =\pi d[/tex]

[tex]C = 3.142 * 24[/tex]

[tex]C = 75.408[/tex]

The length of the fence is calculated by subtracting the diameter from the circumference:

[tex]Fence = C - d[/tex]

[tex]Fence = 75.408ft - 24ft[/tex]

[tex]Fence = 41.408ft[/tex]

Janice babysat 3 hours each night for 8 nights. She earned a total of $192 babysitting. What was her hourly rate?

A) $3 per hour
B) $8 per hour
C) $24 per hour
D) $192 per hour

Answers

Answer:

1) 7:10

2) $8 per hour

Step-by-step explanation:

Question 1

What we know:

- there are 10 seventh grade students

- there are 7 sixth grade students

Therefore, the ratio of sixth-grade students to seventh-grade students is 7:10.

Question 2

What we know:

- Janice babysat 3 hours each night

- Janice babysat for 8 nights

- she earned $192

First, we need to find the total number of hours that she babysat. Because she babysat for 3 hours each night for 8 nights, we can find this by multiplying 3 and 8:

3×8=24

Therefore, Janice babysat for 24 hours in total.

Because she earned a total of $192, divide 192 by 24 to find her hourly rate:

192÷24=8

Therefore, Janice has an hourly rate of $8 per hour.
