A marathon is 131\5 miles long. If 4 people divide the distance equally, how many miles does each person need to run?

328.75 miles

Step-by-step explanation:

Step one:

given data

A marathon is 131\5 miles long (note the format of the length of the marathon  1315 miles)

We are required to divide the length of the marathon by 4

=1315/4

=328.75 miles

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
