Answer:

13,200 feet

Step-by-step explanation:

So, the rocket starts descending at a given rate and time, so we first need to find the length it passed during that descent.

Length equals to speed multiplied with time:

s = v • t

since speed is given in feet per second, we need to convert minutes to seconds; if one minute has 60 seconds, then two minutes have 120 seconds.

s = 15 feet/s • 120 s

s = 1800 feet

So, the rocket descended 1800 feet, but it still has 11,400 feet to the Moon's surface. That means that the rocket was on 11,400 + 1,800 = 13,200 feet elevation when it started to drop.

It is a solid shape that contains lateral surface and two circular bases which are parallel and congruent.
ad-work [718]

Answer:

B (cylinder)

Step-by-step explanation:

Two <u>circular</u> bases which are parallel and congruent :

This basically means that the shape contains a circular base (supposedly the bottom), but since it has two bases, its on the top and the bottom. Because it's congruent, the bases are both equal in shape and size. It is also parallel as well, in which the bases have the same distance between them.

The cube doesn't have any circular bases.

The sphere doesn't have any faces, nor edges.

A cone has a circular base, but it doesn't have two.

A cylinder has two circular bases, as well as they are parallel and congruent.

So, your answer is B (cylinder).

Hope this helped !

If i walk 4 miles per hour how long will it take to walk a mile
fiasKO [112]
Hi there! The answer is 15 minutes.

Walking 4 miles per hour means that it takes you 60 minutes to walk 4 miles. To find the time it takes you to walk 1 mile, we must divide both sides by 4.

4 miles equals 60 minutes.
1 mile equals 60 / 4 = 15 minutes.

The answer is 15 minutes.

Darius counted that he walks 864 steps from his house to the bookstore. If Darius takes 52 steps each minute, about how long wil
MakcuM [25]

Answer:

It would take him approximately 16.62 minutes to reach the bookstore

Step-by-step explanation:

Total steps to the bookstore=Number of steps per minute×number of minutes

where;

Total steps to the bookstore=864 steps

Number of steps per minute=52

Number of minutes=t

Replacing;

864=52×t

t=864/52

t=16.62 minutes

It would take him approximately 16.62 minutes to reach the bookstore
