Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) $\frac{3x+4}{2}$ = 9.5

3x+4 = 9.5(2)

3x = 19-4

x = 15/3

x = 5

b) $\frac{7+2x}{3}$ = 5

7+2x = 5(3)

2x = 15-7

x = 8/2

x=4

The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V(5/7) represent?

Answer:

(B)the volume of the rubber ball when the radius equals five-sevenths feet

Step-by-step explanation:

The Volume of a sphere of radius r can be found using the formula:

$V(r)=\dfrac43 \pi r^3$

Therefore comparing the expression: $V(\dfrac57)$ with V(r):

$Radius, r=\dfrac57$

Thus, $V(\dfrac57)$ is the volume of a ball of radius $\dfrac57$ feet.

The correct option is B.
