A: 100 cm³
This is because the others can be multiplied by something 3 times to get it, but A can not.
A = L * W
A = 20 * 24
A = 480 sq ft.....so her garden is 480 sq ft.
1 qt of fertilizer covers 300 sq ft....so how many quarts will cover 480 sq ft.
set this up as a proportion
1/300 = x / 480....1 qt to 300 sq ft = x qts to 480 sq ft
cross multiply
(300)(x) = (1)(480)
300x = 480
x = 480/300
x = 1.6.....so Danielle will need 1.6 qts to cover her garden <==
Answer:
5.39
Step-by-step explanation:
if you are trying to find MN then it means you need to find the length.
we cant use slope, but we CAN make it a triangle!
*see the attached image*
we can use A^2+B^2 to get what the hypotenuse is or C^2 is
2^2+5^2
4+25=29
the square root of 29 is 5.385
then we just round to the hundreth!
5.39
(8>5, so we bump him up)
hope this helped!
This is the answer 9+(6*2)=21
