Answer:

a. about 15.51 miles, rounded to 15.5 miles

b. about 31.02 miles, rounded to 31 miles

Step-by-step explanation:

Sunday Monday Tuesday Wednesday Thursday Friday Saturday

10 20 40 80 160 320 640

1280 2560 5120 10240 20480 40960 81920

81920/5280 = 15.51515151, rounded to the nearest tenth of a mile, 15.5 miles

Question b asks for how many miles in total has he ran. That means we have to add each of the values shown above and that equals to 163830 feet.

Divide that by 5280 and that equals 31.02 miles, rounded to the nearest tenth, 31 miles.

Point B is the center of a circle, and AC is a diameter of the circle. Point D is a point on the circle different from A and C.

BA and BD are radii of the circle, so triangle ABD is isosceles. Then angles BDA and BAD are congruent, and the remaining (central) angle ABD has measure

$m\angle ABD=(180-2\cdot20)^\circ=140^\circ$

Angles ABD and CBD are supplementary, so

$m\angle CBD=(180-140)^\circ=40^\circ$

and the answer is E.
