Answer:

A = 12 ft

Step-by-step explanation:

Perimeter ( of SQUARE) B = 64

  then each side = 64/4 = 16

AREA of SQUARE C = 400

    side X side = 400

        then side = sqrt 400

Now use Pyhtagorean Theorem to find leg of right triangle that is

   side A  Side B  hypotenuse Side C

A^2 + 16^2 = (sqrt 400)^2

A^2 = 400 - 256

A^2 = 144       then A = 12  Ft

When James family went on the road to the carnival they were stuck in traffic. After a 20 minutes they are were 30 more miles le
Assoli18 [71]

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Are the fractions 1/5 , 5/5 , and 5/1 equivalent?Explain.
NeX [460]
<span><u><em>Answer:</em></u>
They are not equal

<u><em>Explanation:</em></u>
<u><em>Let's take a look at each one of them separately:</em></u>
</span>\frac{1}{5}<span> : This fraction is in the simplest form. It is equivalent to 0.2
The fraction is formed by dividing one part over five

</span>\frac{5}{5}<span> : This fraction is not in the simplest form. We can divide 5 by 5 and the answer would be 1. Therefore, </span>\frac{5}{5}<span> is equivalent to 1

</span>\frac{5}{1}<span> : This fraction is not in the simplest form. We can divide 5 by 1 and the answer would be 5. Therefore, </span>\frac{5}{1}<span> is equivalent to 5.

Based on the above, we can cnfirm that 0.2 , 1 and 5 are not equivalent.
Therefore, the given fractions are not equivalent

Hope this helps :)</span>

How many different triangles can be constructed using angle measurements 81 52 and 47? I need the answer really fast and like ri
solniwko [45]
The options are:
A) exactly one triangle;
B) no triangles;
<span>C) more than one triangle.</span>

First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180

We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.

With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.

Hence, the correct answer is C) more than one triangle.
