Answer:

Part A:Using Pythagorean Theorem a² + b² = c²

Part B: Unknown

Step-by-step explanation:

Part A: Its literally on your paper "Pythagorean Theorem in Three Dimensions"

Part B: you would need 2 sides of the triangle to use Pythagorean Theorem or at least 1 side and 1 angle in Trigonometry. But Part B just gives 1 side being 10 ft (base).

so the triangle would look like:

10² for the base.

x² for the guy wire.

y² for the pole.

to my knowledge its not possible to find the answer of the wire with only 1 side.

Show Work Find the slope (5,-3), (-7,0)

Alex777 [14]

You'd use the equation y2-y1/x2-x1

0-(-3)/-7-5 = 3/-12 = -1/4

So -1/4 would be the slope
m= -1/4

Paul travel to the lake and back. The trip took 3 hours and the trip back took 4 hours He averaged 10 mph faster on the trip the

ollegr [7]

Answer:

40 mph

Step-by-step explanation:

We assume "outbound" refers to the trip to the lake. 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.

During the first hour of operation the farm stand owner sold 15% of the apples he had. On the second hour he sold 20% of the rem

Lelechka [254]

Answer:

200 kg

Step-by-step explanation:

First hour he sold 15% (remaining is 85%)

Second hour he sold 20% of remaining (which is 85%) -- so he sold $(0.2)(0.85)=0.17$ , which is 17% (remaining 85-17=68%)

Third hour he sold 25% of remaining (which is 68%) -- so he sold $(0.25)(0.68)=17$ , which is 17%

In third hour he sold 34, so 17% is 34. To find total he initially had, we need to find (100%). We can setup the ratio (letting x equal his initial amount):

$\frac{0.17}{34}=\frac{1}{x}\\0.17x=34\\x=\frac{34}{0.17}=200$

Initially the farm stand owner had 200 kg of apples.
