Subtract 6.7 from 20. This is 13.3. Divide 13.3/5 is 2.66. That is the answer
Answer:
y = -13
Step-by-step explanation:
5y + 2(y - 2) = 8y - 3(7 - 10)
5y + 2y - 4 = 8y - 21 + 30
7y - 4 = 8y + 9
-4 = y + 9
-13 = y
y = -13
Answer:
The determinant of the matrix given is -49
Step-by-step explanation:
We are given determinant
The determinant can be found as follows
Now solving:
So, determinant of the matrix given is -49
First find the volume of the cylinder, then the volume of the cone, and after you can add the two volumes.
Cylinder:
V = π r^2 h
h = 12 inches
r = 4 inches
V = π(4^2)(12)
V = 192π
Cone:
V = 1/3 π r^2 h
h = 6 inches
r = 4 inches
V = 1/3 π (4^2)(6)
V = 32π
Now adding the two volumes, 192π + 32π = 224π cubic inches
