It helps to think of a simpler problem. Let's say mpg is 20 and 10% higher on a smooth road.

How many miles will you get with one gallon on a regular road?

How many more miles will you get on a smooth road? 10% more, right? How much is that?

OK - so you've now solved a simpler problem. Use the exact some process to solve your, more complicated, problem.

HELP ASAP PLZ :)

Natalija [7]

for the triangle...

b=2h

a=(1\2).bh=648

(1/2).2h.h=648

h2=648

h-18|2 in

h=36|2 in

for the rectangle...

L=3+w

a=l+w=648

{3+w}w=648

w2+3w-648=0

Only positive W values make sense here..

w-24=0

w=24 in

So..

L=3+24

Segment AB is completely rotated about the y-axis to form a 3-D figure. Find the volume of the figure. The

Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = $\frac{4}{3}$ x $\frac{22}{7}$ x $(6)^{3}$

= $\frac{88}{21}$ x 216

= 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.
