If the ratio of the radii of two spheres is 1 : 8, what is the ratio of the surface areas of the two spheres?

1 answer:

5 0

The surface area of a sphere is 4pi*r^2.

4pi is a constant, so we can ignore it. That means the ratio of the surface areas is determined by the radii squared.

1^2 = 1

8^2 = 64

The answer is 1:64

Tasha went golfing. Tasha hit the ball 220 yards down the fairway and then 165 yards to the hole. What would have been the short

steposvetlana [31]

Answer:

385 yards

Step-by-step explanation:

From the information provided we can only assume that the two hits that Tasha performed were in a straight line and in the same direction. Otherwise we would need to know the direction and/or angle of the shots. Assuming they were straight, the shortest minimum distance between the tee area and the hole would be calculated by adding the distance of the two shots.

220 yards + 165 yards = 385 yards

What is the equation of this line?<br>y = -4×<br>y = 4×<br>y = - 1/4×<br>y = 1/4×

sashaice [31]

The answer is the third choice: y=-1/4x.

We find this by remembering that slop is rise over run. Since the rise is -1 and the run is for we can make it -1/4 as the slope, which is next to the x term. Since the y intercept is at the origin we do not have a b term from the formula y=Mx+b.
