Mr. Hammond is the volunteer coordinator for a company that puts on running races. Last year, the company organized 7 short race
worty [1.4K]

Answer:

28 short race volunteers

76 long race volunteers

Step-by-step explanation:

Let :

Short races = a

Long races = b

LAST YEAR:

7a + 8b = 804 - - - - (1)

THIS YEAR:

11a + 5b = 688 - - - (2)

Multiply (1) by 5 and (2) by 8

35a + 40b = 4020

88a + 40b = 5504

Subtract

-53a = - 1484

a = 1484 / 53

a = 28

Put a = 28 in equation (1)

7(28) + 8b = 804

196 + 8b = 804

8b = 804 - 196

8b = 608

b = 76

28 short race volunteers

76 long race volunteers

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>

Rina8888 [55]

Interesting question.

It will describe a multi step proof if the givens have to be restated.


It does depend on theorems and postulates or could.


Geometric statements require that they logically fall into the pattern needed for a proof. This statement is also true.


But the best answer is D. If you provide 1 counterexample, you don't need to go any further. <<<<< Answer.
