A family drives to the beach. A. On the first day, the family drives 3/5 of the total distance. B. On the second day, the family drives 8/20 of the total distance. What fraction of the total distance does the family drive on these two days 19/20
18/20
15/20
20/20=1 help please

20/20: D

Step-by-step explanation:

First turn both the fractions into twentieths.

3/5 = 12/20

8/20

Then add 12/20+8/20=20/20

20/20 = 1

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.

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
