Hello!

If there are 32 people in total in the class, and 20 of them are girls, that means there are 12 boys in the class

so the ratio of boys to girls is 12:20

to get simplest form, divide by the greatest common factor. which in this case, is 4.

12 / 4 = 3

20 / 4 = 5

your final answer is: boys:girls, 3:5

I hope this helps, and have a nice day!

Why can’t one of the names be PNM, or MPN for the plane? But MNP can? What’s the difference, and why?

Savatey [412]

The names PNM and MPN are perfectly valid. The order of the letters doesn't matter. In fact, there are 6 ways to name this plane if we just use the 3 letters. If we include "plane Z", then there are 7 total ways to name the plane.

For some reason, your teacher wants P to be the third letter as s/he mentioned MNP and NMP. But again, the order doesn't matter.

Which expression is equivalent to 6(3+0.05)?

Gnesinka [82]

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .
