Answer: Choice A
The volume expression is 4/3 times pi times (3x)^3
===================================================
The volume of a sphere is found through the formula
V = (4/3)*pi*r^3
so we start with the fraction 4/3, multiply it with pi, and then multiply it with r^3
In this case, the radius is r = 3x because this is half of the diameter d = 6x
We simply replace the r with 3x in that formula above
V = (4/3)*pi*r^3
V = (4/3)*pi*( r )^3
V = (4/3)*pi*(3x)^3 ... replace r with 3x
Can you insert a photo of the question please it would greatly help me answer this
Answer: length = 62 yards and width = 3 yards
Step-by-step explanation:
Answer:
The answer is letter A.
(8x³ + 2x² - 7x + 2) ÷ (2x - 1)
8x³ + 2x² - 7x + 2 ÷ 2x - 1
(2x-1)(4x²+3x-2)÷2x-1
cancel 2x-1 so that the answer is 4x²+3x-2.
Cherry pie is $ C.
Pumpkin pie is $ P.
C + 9P =60 -------> C=60 - 9P
11C+4P = 90
11(60 - 9P) +4P=90
660 - 99P + 4P = 90
-95P = -570
P =570/95 = 6
P=6
C=60-9*P=60 - 9*6= 60-54=6
C=6
Answer: 1 cherry pie -$6, 1 pumpkin pie - $6.
Check:
11C+4P = 90 , 11*6 +4*6 =90, 66+24=90, 90=90 True
