An equation that could be used to find the percent change, p, in the number of employees is:
Given that, Over the course of a year, a company goes from 115 employees to 124 employees.
Given that "p" represents the percent change
Percentage change equals the change in value divided by the absolute value of the original value, multiplied by 100.
Change in number of employees = present count – previous count
So, change in number of employees = 124 – 115 = 9
The equation that is used to find the percent change is:
The answer is: The diameter is 4 centimeters.
The explanation is shown below:
1. The volume of the cylinder is:
Where is the radius (
) and
is the height (
).
Then:
2. The total volume of the 12 spheres is:
3. The volume of the cylinder and the total volume of all the 12 spheres, are equal, therefore:
4. Now, you must solve for the radius:
5. The diameter is:
Answer:
A. =
Step-by-step explanation:
of the students wore shorts.
of the students wore jeans.
Converting the fractions of the students who wore shorts and jeans respectively;
= 0.25
= 0.25
This means that the ratio of students who wore shorts is the same as that of students who wore jeans.
