This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
Answer:
x = 4 2/3
Step-by-step explanation:
x = 5 - 1/3
x = 4 2/3
45% of 20
20 times 0.45
= 9
The answer is 9
Answer:
Radius is 5/π or 1.59
Step-by-step explanation:
C = 2πr
<u>Step 1: Solve for r</u>
C = 2πr
10/2 = 2πr / 2
5 / π = πr / π
5/π = r
Answer: Radius is 5/π or 1.59
