W Rosa counted some animals at a farm. 5 of them were pigs and 20
were other animals. If this trend continues and she counts 10 more
animals, how many of them will be pigs?

Answer

2

Step-by-step explanation:

The ratio of pigs to other animals would be 5:20, which is 1:4 simplified.

That means that the amount of pigs is a quarter of other animals.

1+4 = 5

10/5 =2

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.
