To find the approximate volume that was released you will find the volume of the sphere before and after the water was released and subtract them.  Use the formula for finding the volume of a sphere to do this.

Before:  

V=4/3 x pi x r^3
    4/3 x 3.14 x 4.5^3
V = 381.51 cubic inches

After:

V=4/3 x pi x r^3
    4/3 x 3.14 x 3.6^3
V = 195.33 cubic inches

381.51 - 195.33 = 186.18 cubic inches


The answer is choice B.

Which statement is true about the flight of 2 rockets?
umka21 [38]

Answer:

  The first rocket, g(x), reached its maximum height before the second rocket, h(x).

Step-by-step explanation:

Each equation is in vertex form, so we can read the vertex of the rocket's path from the equation.

  y = a(x -h)^2 +k . . . . . . has vertex (h, k)

__

g(x) has vertex (time, max height) = (4, 170).

h(x) has vertex (time, max height) = (5, 170).

The rockets have the same maximum height (170), but the first rocket, g(x), reaches that height in 4 seconds, one second sooner than the second rocket, h(x).

The first rocket, g(x), reached its maximum height before the second rocket, h(x).

In quadrilateral QRST, angle rst measures (5x + 15)o. Angle TQR measures (4x + 3)o.
sattari [20]
2(5x + 15) + 2<span>(4x + 3) = 360
10x + 30 + 8x + 6 = 360
18x = 324
    x = 18

so

RST = </span><span>5x + 15 = 5(18) + 15 = 105

answer

RST = 105 degree</span>

Which of the following statements are the same? (A) x -= x + 4 (B) x = x + 4 - x (C) x = x - (x + 4) (A) and (B) are the same (A
Nesterboy [21]

Answer: (A) and (B) are the same

Step-by-step explanation:

for (A)

x-=x+4

x=x-(x+4)

x=x-x-4

x=4

for (B)

x=x+4-x

x=4

for (C)

x=x-(x+4)

x=x-x-4

x=-4

so (A) and (B) are the same because the value of their x is +4
