break it up into simpler shapes. See the photo.
There is:
trapezoid
A = 0.5(3.2+6.5)4.5
= 21.825

triangle
A = 0.5(2.7)4.5
= 6.075

rectangle
A = 1.8(4.5)
= 8.1

Total Area = 21.825 + 6.075 + 8.1
= 36

Linear equation 4.5 + 1.5y=24 x-y=4

WARRIOR [948]

4.5x + 1.5y = 24 ⇒ 4.5x + 1.5y = 24
1.0x - 1.0y = 4 ⇒ 4.5x - 4.5y = 18
 6y = 6
 6 6
 y = 1
 4.5x + 1.5(1) = 24
 4.5x + 1.5 = 24
 - 1.5 - 1.5
 4.5x = 22.5
 4.5 4.5
 x = 5
 (x, y) = (5, 1)

Alice works at a health care facility. She has measured the hemoglobin levels of 200 people. The data follows a normal distribut

amid [387]

This is a normal distribution with a Mean: 14 g/dL and a Standard deviation: 1 g/dL.
A ) Hemoglobin levels less than 13:
13 = 14 - 1 = Mean - 1 SD
0.16 x 200 = 32
Answer: 32 people.
B ) Hemoglobin levels greater than 14 :
0.50 x 200 = 100
Answer: 100 people.

what is 40% off of $712.00 please explain how you got your answer as if you were teaching me how to do it.

Vikentia [17]

Answer: $284.80

look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:

1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%

2nd. Next, you do 0.40 x 712.00 = or

712.00

x 0.40

______

$284.80
