**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

DO **NOT** SQUARE THE ANSWER WHEN FINDING **PERIMETER**

When she was younger, Mary had to look up at a 68 degree angle to see into her father's eyes whenever she was standing 15 inches away. How high above the flat ground were her father's eyes if Mary's eyes were 32 inches above the ground?

### Answers

Answer:

69 INCHES

Step-by-step explanation:

Given that :

Height of father's eye above the flat ground :

Kindly check attached picture for diagram:

To obtain the value of h ; we can use Pythagoras rule ;

Tan θ = opposite / Adjacent

Tan 48 = h / 15

15 tan 48 = h

37.126302 = h

h = 37.

Hence, height of father's above the flat ground :

h + 32 = 37 + 32= 69 inches

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

what is the range shown in this table

### Answers

**Answer:**

14

**Step-by-step explanation:**

Range is, basically, the span of all y-values.

To find range, you take the highest y-value and subtract from it the lowest y-value.

Here the highest "y" is 7 and the lowest is -7, so the range is 14.

4x - 2(x - 4) = -8 + 4x +4
