Answer:

Volume of sphere A = 128x (Approx.)

Step-by-step explanation:

Given:

Radius of sphere A = 2 x Radius of sphere B

Volume of sphere B = 16x

Find:

Volume of sphere A

Computation:

Volume of sphere = (4/3)(π)(r)³

Volume of sphere B = (4/3)(π)(r)³

16x = (4/3)(π)(r)³

16x = (4/3)(22/7)(r)³

16x = (88/21)(r)³

Radius of sphere B = 1.56∛x Approx.

Radius of sphere A = 2 x Radius of sphere B

Radius of sphere A = 2 x 1.56∛x

Radius of sphere A = 3.12∛x Approx.

Volume of sphere A = (4/3)(π)(r)³

Volume of sphere A = (4/3)(22/7)(3.12∛x)³

Volume of sphere A = (88/21)(30.37∛x)

Volume of sphere A = 127.27x

Volume of sphere A = 128x (Approx.)

Solve the following equation for x: 6(4x+5)= 3(x+8)+3. Round to the nearest hundredth.
gavmur [86]
6(4x + 5) = 3(x + 8) + 3
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
24x - 3x = 27 - 30
21x = - 3
x = -3/21
x = - 0.143 <==

The length of a pen is 5 more than its width.The perimeter is 26 m.Find the length and the width.
meriva
P=2l+2w

Since it is given that P=26m, length is 5 more than its width (w+5), we'll work it out in the perimeter formula.

26=2(w+5)+2w
26=2w+10+2w
26=4w+10
4w=26-10
4w=16
w=4

Thus the width is 4m. Let's find the length.

l=w+5
l=4+5
l=9

The length of a pen is 9m.

Vesnalui [34]
38.4 is the area. it’s 8.5 ft long so you do 8.5x2 and you get 17, and then for 10.7 you do 10.7x2 and get 21.4, then you add 21.4 and 17 together.
