The math team has 11 boys, 10 girls, and 1 coach. What is the ratio of coach to students?
Group of answer choices

11/1

1/21

1/11

21/1

1:21

Step-by-step explanation:

We know that if they say students they mean both boys and girls so we add 11 and 10 to make 21 and since its, (COACH,) and then student we do 1:21 and not 21:1!

1/21

Step-by-step explanation:

First we need to figure out how many students are in the class.

10 + 11 = 21

Then we need to make a ratio

1/21

For every 21 students there is 1 coach

If you look at the question it says from coach to students so we do 1 coach to 21 students which is why 21/1 is wrong

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

step-by-step explanation:

if x = 2 you have to find x to finish the problem
