Answer;-1.5238095238
First step; 8/15

8/15 = 0.53 and so on in a repeating form. (0.53333333333)

Divide; 0.53 / -0.35

= -1.5238095238

Remember, when dividing fracitons, invert and multiply or
(a/b)/(c/d)=(a/b)(d/c)=(ad)/(bc)

also, (+)/(-)=(-)

convert -0.35 to fraction
-0.35=-0.35/1=-3.5/10=-35/100

now we have
(8/15)/(-35/100)
we know the end result is negative so discard that
(8/15)/(35/100)
35/100 simpifies to 7/20
(8/15)/(7/20)
invert ane multiply
(8/15)(20/7)
(8*20)/(15*7)
160/105
32/21
negative
-32/21

If DE = 37 cm and EF = 16 cm, then what are the possible lengths for DF so that DE,EF, and DF can form a triangle? Explain your

chubhunter [2.5K]

Answer:

The length of DF must be between 21 and 53.

Step-by-step explanation:

In a triangle, the length of two sides added together must exceed the length of the 3rd side. So, since EF is the shortest of the two givens, we know that EF + DF must be greater than DE. So we can plug in these numbers to find the minimum.

EF + DF > DE

16 + DF > 37

DF > 21

Now, for the upper maximum, we know that the two given lengths must be greater than the length of DF. So again, we can solve for the maximum using the amounts.

DE + EF > DF

37 + 16 > DF

53 > DF

With these two in mind, we know that DF must be between 21 and 53
