The ratio of red cars to blue cars in a parking lot was 5: 3.if there were 40 red cars, how many blue cars were there? ?

24

Step-by-step explanation:

The 5 part of the ratio represents 40 cars, thus

40 ÷ 5 = 8 cars ← value of 1 part of the ratio

3 parts = 3 × 8 = 24 ← number of blue cars

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.
