Answer:

b=8

Step-by-step explanation:

This is a right triangle, as we can see from the box in the corner.

We can use Pythagorean theorem to find the unknown side

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

15^2 +b^2 = 17^2

225 + b^2 =289

Subtract 225 from each side

225-225 + b^2 = 289-225

b^2 =64

Take the square root of each side

sqrt(b^2) = sqrt(64)

b = 8

ollegr [7]

Answer:

  40 mph

Step-by-step explanation:

We assume "outbound" refers to the trip <em>to the lake</em>. The ratio of speeds is inversely proportional to the ratio of times, so ...

  outbound speed : inbound speed = 4 : 3

These differ by one ratio unit, so that one ratio unit corresponds to the speed difference of 10 mph. Then the 4 ratio units of outbound speed will correspond to ...

  4×10 mph = 40 mph

Paul's average speed on the outbound trip was 40 mph.

___

The distance to the lake was 120 mi.

((3^3 - 7) • 5)/10 + ((1+3+6+9)-10)
jasenka [17]

Answer:

19

Step-by-step explanation:

(33−7)(5)/10+1+3+6+9−10

= (27−7)(5)/10+1+3+6+9−10

= (20)(5)/10+1+3+6+9−10

= 100/10+1+3+6+9−10

=10+1+3+6+9−10

=10+4+6+9−10

=10+10+9−10

=10+19−10

=10+9

=19
