Answer:

176.89in^3

Step-by-step explanation:

when finding the volume using the surface area, the best method that comes in my mind is finding the ratio between the surface area and volume which would be r/3 for a sphere. So if given that the surface area of the sphere is 152.39 square r/3=around 1.161, and when multiplied by 152.39 is around 176.89. another similar method is deriving the radius when given its surface area which is simply taking the square root of the surface area/4pi which turns out to be 3.482357088 or 3.48 which can then be plugged into the volume formula as the radius which is (3.48^3*4pi)/3 which turns out to be the same answer!

Answer:

The slope of the line 3.

Step-by-step explanation:

The line is going through 3. Although it is not -3, because if the line is sloping upward from left to right, then the slope is positive (+). If the line is sloping downward from left to right, the slope is negative (-).

Tiffany is filling her daughter's pool with water from a hose. She can fill the pool at a rate of LaTeX: \frac{1}{5}1 5gallons/s

Hitman42 [59]

Answer:

25 seconds

Step-by-step explanation:

You have a rate of:

$\dfrac{1}{5}gal/s$

And you want to find how many seconds it would take to fill in 5 gallons of water. Using the rate, we use it as a conversion factor from rate to seconds:

$5gal\times\dfrac{1sec}{\frac{1}{5}gal}=\dfrac{5sec}{\frac{1}{5}}=25sec$

£150 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H

Sauron [17]

Answer:

David receives £90

Step-by-step explanation:

Let David's share be D

Let Mark's share be M

Let Henry's share be H

From the question, we obtained the following data:

David gets twice as much as Mark i.e

D = 2M

M = D/2

Mark gets three times as much as Henry i.e

M = 3H

H = M/3

H = (D/2) /3

H = D/6

The sum of their shares is £150 i.e

D + M + H = 150

D + D/2 + D/6 = 150

Multiply through by 6 to clear the fraction

6D + 3D + D = 900

10D = 900

Divide both side by the coefficient of D i.e 10

D = 900/10

D = 90

Therefore, David receives £90
