Answer: 1.41 hours
<u>Step-by-step explanation:</u>
Geoff: 2.5 hours = 1 job
Max: 3.25 hours = 1 job
Together: 
⇒ 
⇒ 3.25x + 2.5x = 8.125
⇒ 5.75x = 8.125
<u>÷5.75 </u> <u> ÷5.75 </u>
x = 1.413
Answer:
8:27
Step-by-step explanation:
1 way to do it is...
The volume of a sphere is 4/3*pi*r^3. Plugging in 2 and 3 in for the radii you get the volumes are about 33.51 and 113.1, which is an 8:27 ratio.
Another way to do it is...
The ratio of the radii is 2:3 and a radius is 1-dimensional. The volume, however is 3-dimensional. To get from 1-D to 3-D, you have to cube the numbers. 2^3 is 8 and 3^3 is 27, so the ration is 8:27.
Answer:x+85=x+105
x+x=105+85
2x=190
x=190/2
x=95
