Answer and Explanation:</h2><h2 />
The density of a substance is defined as its mass per unit volume. In a mathematical language, this can be written as follows:
From the problem, a student is trying to calculate the density of a ball. She already knows the mass, but is facing a problem because she also needs to find the volume. From geometry, we know that the volume of a sphere is:
Since a ball is a sphere, then the student can use this formula. She just need to measure the radius of the ball and compute the Volumen, then she have to plug both the value of the mass and the value of the Volume in the equation 
. An easy way to find the radius is to take the measure of the diameter of the ball and divide that value by 2.
The answer to this question is 23.2
Answer: -4,-3,-2,-1,0,1,2,3
Step-by-step explanation: they are asking you to put all the integers -4 and 4 in ascending order so, you must start from -4 and go up which is moving to the positive side on the number line and end at 4.
182 would be the correct answer
10 miles per second in feet per second is 14.67 feet per second
Step-by-step explanation:
The average speed of one team in a relay race = 10 miles per hour.
We need to find the speed in feet per second.
1 mile per hour = 1.467 feet per second
So, Speed in feet per second is:
1 mile per hour = 1.467 feet per second
10 miles per hour = 10*1.467 feet per second
= 14.67 feet per second
So, 10 miles per second in feet per second is 14.67 feet per second
