When dividing 1/8 by 2
we have to first take the reciprocal of 2
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is

we need to find the reciprocal of

which is

then

when 'of' function is used it means to multiply the 2 fractions
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators
is

answer is
Average speed is ALWAYS calculated as total distance / total time
<span>total distance is 100mi </span>
<span>total time is (50mi / 33) + (50mi / 80) </span>
<span>total time is = 1.52 + 0.625 = 2.145 </span>
<span>so average speed going to grandmothers house is 100mi / 2.145 hrs = 46.62 mph </span>
<span>on her return trip </span>
<span>x = V1 x t/2 + V2x t/2 </span>
<span>100 = 33t/2 + 80t/2 </span>
<span>100 = 113t/2 </span>
<span>t = 100x2/113 = 1.7699hrs </span>
<span>average speed = 100mi/1.7699hrs = 56.60mph</span>
Answer: m<5 is 71 degrees, m<8 is 109 degrees
Step-by-step explanation: M<5 and m<1 are corresponding angles, so they have the same angle measurement.
M<5 and M<8 are angles on a line, meaning they must add up to 180 degrees, so you subtract m<5's angle measure from 180 to find that m<8 is 109 degrees.
Hope this helps.
