Find the circumference of the pool. I guess you guys here mostly replace pi with 3.14 so that's what we will do. C = 3.14(16) and that gives us a circumference of 50.24 ft.
Answer:
Joe: 3 hrs
Janet: 6hrs
Step-by-step explanation:
joe takes x hours
so in 1 hr he does 1/x of the garden
janet takes 2x hours
so in 1 hr she does 1/(2x) of the garden
In one hour together they do 1/2 of the garden
1/x + 1/(2x) = 1/2
2/(2x) + 1/(2x) = 1/2
3/(2x) = 1/2
Cross multiply
6 = 2x
x = 3
Joe: 3 hrs
Janet: 6hrs
Answer:
0.56
Step-by-step explanation:
im not really sure on this one but i know u have to divide ..
In one dimensions (i.e. with standard numbers and not points with more coordinates) the midpoint is the same as the average.
The average of two numbers is their sum divided by two.
So, we have -4+20=16. Divide this by two to get 8.
