The time taken to complete the entire project is 12 hours.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
75% = 9 hours
The entire project = 100%
So,
75% = 9 hours
Multiply 100/75 o on both sides.
100% = 100/75 x 9 hours
100% = 12 hours
Thus,
12 hours to complete the entire project.

peyton ran 4/5 of a mile in 1/8 of an Hour. What is Peyton's constant of proportionality in miles per hour?
Answer:
6.4 Miles Per Hour
Step-by-step explanation:
Let h be hours
Let mi be miles
We put this in equation form
4/5mi = 1/8h
In order to calculate the rate we would have to make h singular therefore we multiply both sides by 8
4/5mi * 8 = 1/8h * 8
= 32/5mi = h
= 6.4mi = h

A navy submarine descended at a rate of 4 feet per second. a. Write the descent rate as an integer. b. Write an expression to find the submarine's elevation after 5 minutes.
Answer:
1200
Step-by-step explanation:
Since the value they are asking for is in minutes, we need to convert seconds to minutes. We can do that by multiplying 4 and 60, because there are 60 seconds in a minute, and we need to find the value of one minute. Also because the value they gave is 4. When we do this, we get 240. To get the final answer, we need to multiply 240 and 5, because 240 is the descending rate per minute, and they are asking for 5 minutes. When we do this, we get 1200.
