1 answer:

3 0

Hello!

If we want to find the mean (average) of any set of numbers, all you need to do is add the set together, then divide by how many numbers are in the set.

When we add all the numbers we get: 100

Next we just divide by the number of people which is 10: 100 divided by 10 is 10

So, the mean age of the swimmers on the team is an even number of 10.

The number of pencils in one pack = 6

= > $118 \times 2$

=> 236 Pencils

We know that a pack contains 6 pencils, so the number of pack that has to be bought , in order to have 236 pencils will be

On substituting the values

=> $\frac{236}{6}$

=> 39.33

What is the weight of a bowling ball with a 5 in. radius if we know that one cubic inch weighs 1/100th of a pound?

lorasvet [3.4K]

<h2>Greetings!</h2><h3>To find the total area of the bowling ball, which we presume is spherical, the equation is:</h3>

$\frac{4}{3}$ πr³

<h3>So we know that the radius is 5, so we can substitute that into the equation:</h3>

$\frac{4}{3}$ x π x 5³ = 523.599 or 524 to 1dp.

<h3>Seeing as this is 524 cubic inches, we can convert this into pounds by dividing this by 100, because one cubic inch weights $\frac{1}{100}$ as stated.</h3>

524 ÷ 100 = 5.24lb

<h3>So your answer would be B, 5.24lb.</h3>
<h2>Hope this helps!</h2>
