The volume of a prism is worked out by first calculating the area of the surface and then multiplying that figure by the length of the prism

You would multiply the width, by the height, by the length.

Hope this helps! (:

1. 7 and -7 are both 7 units away from 0. They are 14 units away from each other. Absolute value helps because rather than 7+(-7) being 0 absolute value makes anything positive so it becomes 7+7=14 to be able to count the units between the two.

2. 5 and -5 are both 5 units away from 0. They are 10 units away from each other. Absolute value helps because rather than 5+(-5) being 0 absolute value makes anything positive so it becomes 5+5=10 to be able to count the units between the two.

3. 2 and -2 are both 2 units away from 0. They are 4 units away from each other. Absolute value helps because rather than 2+(-2) being 0 absolute value makes anything positive so it becomes 2+2=4 to be able to count the units between the two.

Hope that helps

What is the fraction twelve twentieths in its simplest form

Alla [95]

You mean $\frac{12}{20}$ or $\frac{20}{12}$ ?

If you had meant, $\frac{12}{20}$ , then the simplest form of this fraction would be - $\frac{3}{5}$

Divide both parts of the fraction by 4, and you get $\frac{3}{5}$ the simplest form of the fraction.
Finding out the simplest form of a given fraction is nothing else than cancelation.

Flop it, you have with you - $\frac{20}{12}$
Flop the simplest form of the previous fraction, that's $\frac{5}{3}$

If you had meant $\frac{20}{12}$ , then this will certainly be of any use to you.

HOW TO UNDERSTAND THAT THE FRACTION IS IN ITS SIMPLEST FORM?
Maybe, you are just simplifying and simplifying...but you don't even know when to stop. You can understand whether a fraction is in its simplest form or not by seeing that the numerator and the denominator have a common factor to divide it by, or not.

For instance, consider the case here - $\frac{3}{5}$ or $\frac{5}{3}$ <span>. We can't divide it any further. So, we know that it is in its simplest form.
</span>
L O N G Process:
Well, if you want to divide it by the smallest common factor to its larger, then --
$\frac{12}{20}$ or $\frac{20}{12}$

1) Divided by 2 = $\frac{6}{10}$ or $\frac{10}{6}$

2) Next, also by 2 = $\frac{3}{5}$ or $\frac{5}{3}$

That took much longer, right.<span> So, it is more preferable to divide the fraction by the possible largest common factor, you can guess of.</span>

Which of the following best describes rotational symmetry

Gala2k [10]

Answer: B

Step-by-step explanation:

A best describes the quality of symmetry, not specifically rotational symmetry.

C applies to that of A.

D applies to flipping an image across an axis.

B specifically outlines the symmetry of an object when rotated, thus B would be the most precise answer.
