The Last answer is correct. For math problems i suggest photo math for cellular devices.
<span>Note D = r(t)
20min = 1/3 hr and 10min = 1/6 hr
(1/3hr)30mph + (1/6hr)3mph = 10.5 mi, the total distance traveled.
total distance / total time = average speed = 10.5/(1/3 + 1/6) = 10.5/(2/6 + 1/6)
10.5mi/.5hr = 21mph
Hope This Helps

Answer:
900 degrees
Step-by-step explanation:
This question is asking you to figure out what all the angles in the shape add up to. There is actually a formula for this: a function of the number of sides that a polygon has.
> Memorize this formula if you will need to do these kinds of problems for your tests/quizzes!
(n - 2) * 180
Since this polygon has 7 sides, we substitute n = 7 into the formula, and solve.
(7 - 2) * 180
5 * 180 = 900
The sum of the interior angles of the polygon shown is 900 degrees.

Answer:
it's 180 because 15 boxes multiplied to 12 is 180 all in all marbled
