We know that Bonnie complete her paper route in 45min. So, in 1min she can complete:
![\frac{1}{45}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B45%7D)
of her paper route.
We need to know <span>how long it would take Jean alone, then we will call
this time
x. Working together they last 18min, so </span>in 1min they can complete:
![\frac{1}{18}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B18%7D)
of the paper route.
The paper route working together satisfies the following equation:
![\frac{1}{18} = \frac{1}{45} + \frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B18%7D%20%3D%20%5Cfrac%7B1%7D%7B45%7D%20%2B%20%5Cfrac%7B1%7D%7Bx%7D)
Solving this equation:
![\frac{1}{x} = \frac{1}{18} - \frac{1}{45} = \frac{45-18}{810} = \frac{27}{810}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bx%7D%20%3D%20%5Cfrac%7B1%7D%7B18%7D%20-%20%5Cfrac%7B1%7D%7B45%7D%20%3D%20%20%5Cfrac%7B45-18%7D%7B810%7D%20%3D%20%20%5Cfrac%7B27%7D%7B810%7D)
![x = \frac{810}{27} = 30min](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B810%7D%7B27%7D%20%3D%2030min)
Finally:
It takes 30min to complete the paper route by Jane alone.
Answer: C. not given
Step-by-step explanation:
formula for volume of sphere: V=(4/3)πr³
V=(4/3)πr³
V=(4/3)(3.14)(3)³
V=(4/3)(3.14)(27)
V=113 in³
Answer:
65 i believe
Step-by-step explanation:
first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
