1. The speed of sound in water is 1,500 meters/second. How far can sound travel in 10

baherus [9]

Answer:

900 km
5400 km

Step-by-step explanation:

The speed of sound in water:

s = 1500 m/sec

Time:

t = 10 min = 10*60 sec = 600 sec

t = 1 hour = 60 min = 60*60 sec = 3600 sec

Distance in 10 min:

d = s*t
d = 1500 *600 = 900 000 m = 900 km

Distance in 1 hour:

d = 1500*3600 = 5 400 000 m = 5400 km

Which volume could belong to a cube with a side length that is an integer? Recall the formula Cube volume = s cubed. 18 cubic in

irina1246 [14]

We have been given 4 choices. We are asked to choose the volume that could belong to a cube with a side length that is an integer.

We know that volume of a cube is cube of each side length.

To solve our given problem, we will take cube root of each given value. The cube root of which value will be an integer that will be our correct choice.

A. $s^3=18$

$\sqrt[3]{s^3}=\sqrt[3]{18}$

$s=2.62074$

Since cube root of 18 is not an integer, therefore, 18 is not a correct choice.

B. $s^3=36$

$\sqrt[3]{s^3}=\sqrt[3]{36}$

$s=3.301927$

Since cube root of 36 is not an integer, therefore, 36 is not a correct choice.

C. $s^3=64$

$\sqrt[3]{s^3}=\sqrt[3]{64}$

$s=4$

Since cube root of 64 is 4 and 4 is an integer, therefore, 64 is the correct choice.

D. $s^3=100$

$\sqrt[3]{s^3}=\sqrt[3]{100}$

$s=4.641588$

Since cube root of 100 is not an integer, therefore, 100 is not a correct choice.
