To solve 7-2a-5-14=-2+3a :
1) combine like terms: 7-19 - 2a = -2 + 3a, and then -10 = 5a
2) solve this equation for a: a = -10/5 = -2.
The solution of 7-2a-5-14=-2+3a is a = -2.
Answer:
I do not know this answer to the question. I am so sorry. Ask "LucasPeed"
Step-by-step explanation:
If you need anymore help ask, Brainly. Have a nice day!
In Cartesian coordinates, the region (call it
) is the set

In the plane
, we have

which is a circle with radius
. Then we can better describe the solid by

so that the volume is

While doable, it's easier to compute the volume in cylindrical coordinates.

Then we can describe
in cylindrical coordinates by

so that the volume is

96÷120 =0.8 ⇒0.8 ×100 =80 % :))
