Answer:
<u>10.75%</u>
Step-by-step explanation:
so, you need the total price, which would be 17,850+2,150=20,000 as the whole price of the car, then you need to find what precent 2,150 is of 20,000. then use this formula for finding the precent.
2150/20000 times 100%=10.75%
50:40=x:35
5/4=x/35
times both sides by (4*35)
5*35=4x
175=4x
divide both sides by 4
43.75=x
costs $43.75
1.a sphere with a radius of three units
By definition, the volume of a sphere is:

Substituting values we have:

Rewriting we have:
2.a cone with a diameter of twelve units and a height of three units
By definition, the volume of a cone is given by:

Substituting values we have:

Rewriting we have:
I believe x=3.
4x-3(-2)=18
4x=12
x=3
