An envelope with 96 bookmarks in it has a mass of 1467 grams. The same envelope with 49 bookmarks in it has a mass of 762 grams.

masya89 [10]

If $m$ is the mass of the envelope and $b$ the mass of one bookmark, then

$\begin{cases}m+96b=1467\\m+49b=762\end{cases}$

We have

$(m+96b)-(m+49b)=1467-762\implies47b=705\implies b=15$

Then

$m+96\cdot15=1467\implies m+1440=1467\implies m=27$

so the envelope has a mass of 27 grams.

A triangle has two sides of lengths 4 and 5. What value could the length of the third side be?

Olin [163]

Answer:

2, 3, 4, 5, 6, 7 or 8.

Step-by-step explanation:

We know that the sum of two sides on a triangle should ALWAYS be greater than the third side. Then we have:

5-4 < x < 5 + 4

1 < x < 9

Therefore, the lenght of the third side could be any number between 1 and 9. If the lenght of the third side is an integrer, then the lenght could be:

2, 3, 4, 5, 6, 7 or 8.

Deion misses 4% of the free throws he attempts in a seaon. how many total free throws did he attempt if he missed 17

Burka [1]

He has thrown 425 free throws if he missed 17

<h3>How to determine the total number of free throws?</h3>

The given parameters are:

Proportion of free throw missed, p = 4%

Number of free throw missed, n = 17

Let the total number of throws be N.

So we have

n = p * N

Substitute the known values in the above equation

17 = 4% * N

Divide both sides by 4%

N = 425

Hence, he has thrown 425 free throws if he missed 17
