Answer:
31.77 yd/sec
Step-by-step explanation:
<u>Conversions:</u>
- 1 mile = 1760 yards
- 1 hour = 3600 seconds
<u>Given:</u>

Therefore, to convert 65 mph to yards per second:

1\10 has the greatest value as it is the smallest number diving one
When two lines cross like this, sum of measures of opposite angles is 180.
this means that:
measure angle AEC + measure angle BED = 180
4x-40 + x+50 = 180
5x +10 = 180
5x = 170
x = 34
therefore:
measure angle AEC = 4x-40 = 4(34)-40 = 96
measure angle BED = x+50 = 34+50 = 84
ANSWER

EXPLANATION
We want to evaluate

Use indices to rewrite the expression as:

We know that

So we rewrite the expression to obtain;

This gives us;

This simplifies to
