Find the distance between the points (8, – 7) and ( – 4,9). Hint: Use the Pythagorean theorem

1 answer:

6 0

8+4=12
9+7=16
12^2=144
16^2=256
144+256=400
square root of 400 is 20

therefore the distance from (8, -7) to (-4,9) is 20.

Answer:

The radius of the sphere is $6\ cm$

Step-by-step explanation:

we know that

The volume of a sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

In this problem we have

$V=288\pi\ cm^{3}$

substitute and solve for r

$288\pi=\frac{4}{3}\pi r^{3}$

simplify

$288*3/4=r^{3}$

$r^{3}=216$

$r=6\ cm$

Naddik [55]

Answer:

Company A is 1.99 times B.

Step-by-step explanation:

Company A charges:

$A=70.50+0.50=\$71/mile$

Company B charges:

$B=35.50+0.09=\$35.59/mile$

We just need to divide A by B:

$x=A/B=1.99$

Therefore, company A is 1.99 times B.
