D = 5/6 sqrt(h)
7 = 5/6 sqrt(h)
42/5 = sqrt(h)
h = (42/5)^2 = 1,764/25 = 70.56

The height of the mast is 70.56 miles

The diameter of a sphere is 16 cm. What is the sphere's volume? Round to the nearest tenth.
ohaa [14]

Answer:

V ≈ 2144.70 cm^3

Step-by-step explanation:

Radius is going to be used instead of the diameter. Half of 16 is 8, and so that will be the value that shall be used.

V = (4/3)\pi (8)^3

V ≈ 2144.66 cm^3

V ≈ 2144.70 cm^3

Given the speeds of each runner below, determine who runs the fastest.
alexandr402 [8]

Answer:

Brooke

Step-by-step explanation:

We can solve this by figuring out how far each person runs a second

Stephanie runs 12 feet a second so nothing needs to be done here

Liz runs 306 feet in 38 seconds. To solve for the distance ran in 1 second we can divide (306/38)= around 8 feet

Will runes 1 mile in 491 seconds. A quick search will tell use that 1 mile is equal to 5280 feet and 5280/491 = 10.75

Brooke runs 851 feet in 1 minute or 60 seconds. 851/60 =14.18

Brooke obviously runs the furthest in one second and therefore she's the fastest runner
