A student has a part time job in which she works 4 hour shifts. Her pay scale is $5.25 hour. How many shifts must she work to earn $220?

Earning on one shift = 4**5.25= 21

to earn 220 she had to do 220/21= 10.48 shifts

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.
