Answer:
24¾
Step-by-step explanation:
8/18=11/x
x=11×18/8
x=198/8
x=24¾
Answer:
(y2-y1)/(x2-x1)
Step-by-step explanation:
Average rate of change is just using the slope formula: (y2-y1)/(x2-x1)
This is the order from smallest to greatest: -10,-5,0,5,10
The point-slope form is:

So, here, you just plug in values:

It would be + 1 because remember, the '-' sign just means the opposite of, not subtraction in this case. Also, m = slope.
Answer:
21806 basketballs are needed to fill the gym
Step-by-step explanation:
We have to find both volumes in the same units, so I will use feet for the dimensions, the volume will be in cubic feet. Each feet has 12 inches.
Volume of the gym:
The volume of the gym(rectangular base with height) is given by the multiplication of its dimensions. So
cubic inches
Volume of the basketball:
The basketball is an sphere, so its volume is

In which r is the radius, which is half the diameter.
28.5 inches in diameter, so 2.375 feet in diameter, radius of 1.1875 feet. The volume of the basketball is:
cubic inches
How many basketballs are needed to fill the gym?
This is given dividing the volume of the gym by the volume of a basketball. So
152640/7 = 21805,7
Rouding up
21806 basketballs are needed to fill the gym
