PLS HELP ME! Joye has a circular garden with a diameter of 24 feet. If she uses 2 cups of fertilizer for every 10 square feet, how much fertilizer will Joye use for her garden? Use 3.14 for pi

90.5 cups

Step-by-step explanation:

Step one:

Given data

diameter= 24ft

radius= 12 ft

area= πr^2

Area= 3.142*12^2

Area= 3.142*144

Area= 452.448 ft^2

Hence if  

2 cups of fertilizer for every 10 square feet

x cups will do for  452.448 ft^2

cross multiply we have

x=  452.448 *2/10

x=904.896/10

x=90.5 cups

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
