The height of glass 1 is 7.6
so, you find the volume of glass 2,= 26.376
then you subtract the answer from 80 cubic cm to get the volume of glass 1
80 - 26.376 = 53.694
then you work backwards to get the height, which is 7.6
Answer:
18 years
Step-by-step explanation:
2(8+x) = 34+x
16+2x = 34+x
-18 = -x
X = 45.
Since opposite exterior angles are congruent, you can set the 2 values equal to each other. When you solve for x, you should get 45.
Answer:
"changes the period to pi"
Step-by-step explanation:
f(t) = Sin(t),
Here, t is the period, by definition.
Multiply t by a number that is GREATER THAN 1, makes the period shorter and compressed.
Multiplying t by a number that is between 0 and 1 makes the period expanded.
For the first, if we multiply the period by a, the period becomes 
Since the problem tells us to multiply by 2, we know the period becomes compressed and becomes :

Third answer choice is right.
144 inches. 12 feet in one hour
12 inches per feet
12feet x 12 inches per foot= 144 inches
