To calculate the slope, you can use the formula
In this case,
Your slope is 0/3, which does not make sense so there should be something incorrect about your points.
Answer:
1767.1 inches cubed
Step-by-step explanation:
The volume of a ball, or a sphere, is: 
, where r is the radius.
Here, the radius is r = 7.5. So, plug in this value: 
562.5 pi is about 1767.1 inches cubed.
Thus, the volume is 1767.1 inches cubed.
Hope this helps!
Answer: D = -8
Step-by-step explanation:
combine like terms
Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.
Answer: 4 hours 30 minutes
Step-by-step explanation: 36/8 = 4.5 hours
