Answer:
C 117
Step-by-step explanation:
<2 = 63 vertical angles
<2 = <4 alternate interior angles
<4 + <7 = 180 straight line
63 +<7 = 180
subtract 64 from each side
<7 = 180-63
<7 = 117
Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:
Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =
Since the volume of the cylinder does not changes, we can write:
Rate of change of volume:
Puttiung values, we get
Thus, the radius is decreatsing at a rate 0.78 cm per second.
Answer:
43 1/12
Step-by-step explanation:
Add them together
First we have to have equal denominators
6 3/4 can also be 6 9/12
36 1/3 can also be 36 4/12
We add them to get 42 13/12
12/12 is 1 so we add 1 to 42 and get 43 1/12
Hope this helps
