**Answer 1**

**Answer:**

Area = 24 in²

Perimeter = 24in

**Step-by-step explanation:**

To find the area given the length of the 3 sides:

a= 8in

b= 6.4in + 3.6in= 10in

c= 6in

Add them together:

8in + 10in + 6in

= 24in²

To find the perimeter you do the same thing:

a= 8in

b= 10in

c= 6in

Add them together

=24in

Tan θ = opposite / Adjacent

Tan 48 = h / 15

15 tan 48 = h

37.126302 = h

h = 37.

Kay walks upstairs to make her legs stronger. Every day at work, she walks up 9 flights of stairs. If there are 13 steps in 1 flight of stairs, how many steps does Kay climb in 5 days at work? If you sleep 7 hours every night how many hours are you AWAKE in a year? Tips: There are 24 hours in a day. There are 365 days in a year.

### Answers

Answer: See explanation

Step-by-step explanation:

Every day at work, Kay walks up 9 flights of stairs. If there are 13 steps in 1 flight of stairs, how many steps does Kay climb in 5 days at work?

The number of steps she walks in a day will be:

= 13 steps × 9

= 117 steps

Number from steps in 5 days will be:

= 117 steps × 5

= 585 steps

If you sleep 7 hours every night how many hours are you AWAKE in a year?

The number for hours awake in a day will be:

= 24 hours - 7 hours

= 17 hours

The number for hours awake in a year will then be:

= 17 hours × 365

= 6205 hours
