Answer:
154 in^3
Step-by-step explanation:
Apparently, the outside diameter is 6 inches, so the outside radius is 3 inches. The inside radius is shorter by the wall thickness, so is 3 -1.25 = 1.75 inches.
The volume formula is ...
V = πr^2·h = π(1.75 in)^2(16 in) ≈ 49π in^3 ≈ 153.94 in^3
The approximate inside volume is 154 cubic inches.
Let the number of 2 point shots Sarah made = X
Let the number of 3 point shots Sarah made = Y
Total number of shots Sarah made in all is 8 and it is already given in the problem.
Now in the question, it is also given that Sarah made three times as many 2 point shots as 3 point shots.
Then
X = 3Y
Now we can easily write the equation as
X + Y = 8
3Y + Y = 8
4Y = 8
Y = 8/4
Y = 2
Then the number of 2 point shots Sarah made = 2 * 3
= 6
So Sarah made a total of 6 two point shots.
Answer:
a=7
Step-by-step explanation:
-52 = -17 -5a
Add 17 to each side
-52+17 = -17-5a+17
-35 = -5a
Divide by -5
-35/-5 = -5a/-5
7=a
