Answer:

16km

Step-by-step explanation:

Since its a right angle triangle we can use the pythogorean theorem, which is a^2 + b^2 = c^2

So if we apply it to this situation we get,

12^2 + b^2 = 20^2

144 + b^2 = 400

b^2= 400 - 144

b^2= 256

b= 16

So the answer is 16km

Hope this helped :)

I need to know the answer to this problem. Thanks. I will name Brainliest to the correct answer :)
trapecia [35]

Answer:

422

Step-by-step explanation:

Large rectangle

A = 2(lw+wh+lh)

A = 2(7*10+10*5+7*5)

A = 310

Small rectangle

A = 136

Now the squares that connect both, 4*3

Since you have 1 on each rectangle, the total area for this is 24

add 310 + 136 and substract 24

A class of 33 students elected a class treasurer. There were 11 votes for Candidate A and 15 votes for Candidate B. The remainin
vovangra [49]
To start out, notice that you want the percent of voters that chose candidate A, not the percent of the class that chose candidate A.

Your fraction should be "number that chose candidate A" out of "number of voters," which is the same thing as saying:  
"number that chose candidate A" divided by "number of voters"

1) The numerator of the fraction should be the number of votes for candidate A, which is 11.

2) The denominator of the fraction should be the number of voters. You're told that "t<span>here were 11 votes for Candidate A and 15 votes for Candidate B," so there are:
</span>11 + 15 \: total \: votes

3) Finally put parts 1 and 2 together into a fraction and multiply by 100 to get your percent. That is your final answer:
\frac{11}{11+15}  \times 100

----

Answer: Top right choice, \frac{11}{11+15} \times 100

PLEEEEEEEEEEASSEEEEEEE ANSWER QUESTION IS DOWN BELOW WORTH 15 POINTS each
Svetllana [295]

A ratio shows us the number of times a number contains another number. The ratio of the volume of the model to the volume of the original is 27/2744.

<h3>What is a Ratio?</h3>

A ratio shows us the number of times a number contains another number.

Given that the scale factor is 3:14. Therefore, the ratios can be written as,

(a) The ratio of the surface area of the model to the surface area of the original  is,

Surface area Ratio = (3/14)² = 9/196

(b) The ratio of the volume of the model to the volume of the original.

Volume Ratio = (3/14)³ = 27/2744

(c) The ratio of the width of the model to the width of the original.

Width Ratio = 3/14
