Extra Credit: An older method of estimating body fat percentage was to measure a person's average density (total mass divided by total volume), and apply a formula to convert a body fat percentage. Formula: BF = (4.57/p - 4.142)x100 (where BF = body fat and p = density in g/cm³. A man weighs 260 pounds. His total body volume is measured by a cylinder with a height of 180 cm and a radius of 14 cm. Find his body fat percentage, based upon the given formula (to the nearest percent).

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
