What real life object could a triangular prism be used for

Veseljchak [2.6K]

We can start out simple, so here's some:

If you ever drew a sea saw as a child, or seen it, you probably had seen a part that looks like a triangular prism. It's somewhere in the structure.

Many building infrastructures have them. The roofs of many houses are pointed in some what of a triangle like shape so that rain water can roll off of them easier.

Hope these two help or at least spark some ideas!

Anna earned 22 points on her last test. If there were 40 possible points, what was her percent grade?

dimulka [17.4K]

Answer:

55%

Step-by-step explanation:

Since Anna earned 22 points, and there was a total of 40 points, this means that she scored 22 out of 40 points. You can simplify this by dividing the denominator and numerator by 2. Then, you can multiply both the numerator and denominator by 5 to get a number out of 100.

$\frac{22}{40} = \frac{11}{20}=\frac{55}{100}*100%=55%$
