Answer:
Step-by-step explanation:
To find the volume of the sphere we need to know its radius.
And the radius can be found with the information we have about the surface area.
The formula for the surface area is as follows:
from this formula we clear the radius r:
and we substitute the known value of the surface area, and also the value of 
:
and now that we know the radius we find the volume:
the volume of the sphere is 
Answer:
20 tea bags
Step-by-step explanation:
if 5 is 1 gallon then you do 5x4=20
It is prime, it has no factors besides 1,23
Answer:
1. if x + 5 = 12, then x = 7
<u>:Subtraction property of equality</u>
2. If x + y = 20, and y = 5, then x + 5 = 20.
<u>:Substitution property of equality</u>
3. If 2x3 = 11, then 11 = 2x - 3.
<u>:Symmetric property of equality</u>
Answer:
3 miles
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles
This is the change in miles / change in time.
Chang in miles = 3
Change in time = 1
Slope = 3/1
Slope = 3
