Divide the number of respondents saying it was useful by the total number
63/85 = 0.74
6.9 = 6.9 / 1
Numerator = 6.9 × 10 = 69
Denominator = 1 × 10 = 10
Numerator / Denominator = 69 / 10
Simplifying our fraction
= 69/10
= 69/10
= 6 9/10
Answer: estimate 7
exact: 6 7/15
Step-by-step explanation: for the estimate round 3 4/5 to 4 and 2 2/3 to 3 and 4 + 3 = 7
for the exact number convert 3 4/5 to 3 12/15
and convert 2 2/3 to 2 10 /15
then add 3 + 2 = 5
and 12/15 + 10/15 = 22/15
convert 22/15 to a mixed number which is 1 7/15
then 5 + 1 7/15
answer 6 7/15

So hmm notice the picture below
that's the 30-60-90 rule, notice your triangle, the bottom-left-angle is a right angle, 90°, the angle atop is 30°, so the angle on the bottom-right has to be 60°, thus is a 30-60-90 triangle, and as you can see on the triangle on the left in the picture, those are the ratios for it
so 8 will be x, what is the longer leg or side in yours then? well, is
Answer:
-15/4
Step-by-step explanation:
slope = change in y / change in x = (-7 - 8) / (7 - 3) = -15/4
