The ratio of giraffes to elephants in the zoo is 3:1. If there are 33 giraffes in the zoo, how many elephants are in the zoo?

11

Step-by-step explanation:

33 divided by 3 is 11

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.
