Answer:

score = 63

Step-by-step explanation:

1.  To write the proportion take the score of the test over the number of points and set it equal to the percent over 100

score         90

----------- = -----------

70               100

Using cross products

100 * score = 90*70

100 score = 6300

Divide by 100

100/100 * score = 6300/100

score = 63

You would use the pythagorean theorem. a² +b² =c²

side² +side² = hypotenuse²

So for 1) 8² + 15² = c²
64+225=c²
289=c²
√c² = √289
c = 17

2. 7²+24² =c²
49+576= c²
c²=625
√c²= √625
c = 25

3. 5²+13²=c²
25+169=c²
c² = 194
√c² = √194
c = 13.93

4. 24² + 45² =c²
576 + 2025 =c²
c² = 2601
√c² = √2601
c = 51

5.
Plug each choice into the pythagorean theorem. a² +b² =c²

3²+4² = 5²
9+16= 25
25=25

6²+8²=10²
36+64=100
100=100

16²+63²=65²
256+3969=4225
4225=4225

8²+9²=10²
64+81=100
145=100 Since 145 does not equal 100 it is not a right triangle

Before rock climing, fernando, who is 5.5 ft tall, wants to know how high he will climb. He places a mirror on the ground and wa
aleksandrvk [35]

Answer: 31. 16 ft

Step-by-step explanation:

The other part of the question is:

If the mirror is 34 feet from the cliff side, determine the height of the cliff.

We can solve this problem with geometry, if we imagine two righ triangles (figure attached):

-One formed by Fernando, who is 5.5 ft tall, and the ground

-The other formed by the height x of the cliff, the cliff side and the ground.

In addition both triangles are congruent, hence we can use the following relation to find x:

\frac{5.5 ft}{x}=\frac{6 ft}{34 ft}

Iolating x:

x=31.16 ft This is the height of the cliff
