Answer:
24 hours
Step-by-step explanation:
Kristen = 8 hours
Kristen and Courtney = 6 hours
Courtney = x hours
in six hours kirsten can do 6/8 of the job
6/8 = 3/4
So kirsten is going to be doing 3/4 of the job
Courtney is only going to do 1/4 of the job
Number of hours it takes Courtney to do the job
6/x = 1/4
Cross product
6 * 4 = x * 1
24 = x
x = 24 hours
It will take Courtney 24 hours to type a 50-page paper on her own
Answer:
You have to do 8/100 * 20
Step-by-step explanation:
This would be 5/9 / 3/4 = 5/9 * 4/3 = 20/27 pages per minute
Answer:
Step-by-step explanation:
The perimeter if a plane figure is the total distance around the figure.
Therefore, the perimeter of the given triangle is a + b + c
Perimeter = 5.57 + 8.76 + 8.7 = 23.03 yards.
The formula for determining the area of a triangle is expressed as
Area = 1/2 × base × height
From the diagram,
Base = 8.7 yards
Height = 5.3 yards
Area = 1/2 × 8.7 × 5.3 = 23.055 square yards
I think you do 20(20+x)=31(31+x). Basically you need to set up a proportion
