Use the formula 42600 ÷ (6.9 ÷<span> 100) to calculate this !

</span>42,600 ÷ (6.9 ÷ 100) = <span>617391.304348. Round this to 617391 since you can't sell a percentage of a book.
</span>
To check this, calculate 6.9 percent of 617391.304348. 0.069 · 617391.304348 = 42,600.

10$ is spent on 2 big pails and 1 small one. A smail pail cosf half as much as each big one. How much is spent on a big pail? Ho

Mila [183]

Answer:

<u>$4</u> is spent on a big pail and <u>$2</u> is spent on a small pail.

Step-by-step explanation:

Given:

10$ is spent on 2 big pails and 1 small one.

A small pail cost half as much as each big one.

Now, to find the amount spent on a big pail and on a small pail.

Let the cost of a big pail be $x.$

And the cost of small pail be $\frac{x}{2} .$

As given, there are 2 big pails.

And the total money spent = $10.

According to question:

$(x+x)+\frac{x}{2}=10$

$2x +\frac{x}{2}=10$

$\frac{4x+x}{2} =10$

$\frac{5x}{2} =10$

<em>Multiplying both sides by 2 we get:</em>

$5x=20$

<em>Dividing both sides by 5 we get:</em>

$x=4.$

<em>The cost of a big pail</em> = $4.

<em>So, the cost of a small pail</em> = $\frac{x}{2} =\frac{4}{2}=\$2.$

Therefore, $4 is spent on a big pail and $2 is spent on a small pail.

In a bag of 100 marbles comprised of many colors, 25 are blue. suppose marbles are selected at random.

satela [25.4K]

Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:

$\binom{5}{3}=\frac{5!}{(5-3)!3!}$

$=\frac{120}{2 \times 6}$

$=\frac{120}{12}=10$

Therefore, there are 10 ways we could arrange 3 blue marbles.
