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
Calculate the intercepts bu replacing x or y with 0 and solving for the other.
4x - 1 = 3y + 5
If x = 0,
4(0) - 1 = 3y + 5
-1 = 3y + 5
-6 = 3y
y = -2
If y = 0
4x - 1 = 3(0) + 5
4x - 1 = 5
4x = 6
x = 6/4 or 3/2
x int: (3/2,0)
y int: (0,-2)
Answer:
4c-3=d
Step-by-step explanation:
4c=d+3
4c-3=d
Answer:
See below
Step-by-step explanation:
q = quarters value = .25 q
n = nickels = 4q value = .05 (4q)
summed = 12.60
<u>.25q + .05(4q) = 12.60 </u> <====== <u>can be used to solve the problem</u>
.45q = 12.60
<u>q = 28 quarters then nickels = 4q = 112 </u>
