Answer:
7 minutes
Step-by-step explanation:
The scientist changes the temperature for the solution at a rate of -7°C per minute. We need to find out how long it'll take for the solution's temperature to change from 0°C to -49°C. So, we divide -7 by -49 to find out how long it will take:
-49 / -7 = 7
It will take 7 minutes for the temperature to reach -49°C.
No it should be a 50% chance because the first roll is a independent variable, 6/12=1/2
Answer:
252 cubic yards

So to find the volume, we need to multiply the width, length and height. So we have 12*7*3 or 84*3 or 252.
Step-by-step explanation:
do 590 divided by 90 if that doesn't work multiply it
Answer:
36π inches which is 113.10 inches to the nearest hundredth
Step-by-step explanation:
