In january 2008, the temperature in parts of minnesota fell from 41°f to -13°f over a 24 hour period. what was the average temperature change per hour.

-2.25 degrees an hour

Step-by-step explanation:

So the temperature dropped from 41-0, so that is 41 degrees. Then it dropped 13 degrees below zero, so it dropped a total of 41 + 13 = 54 degrees total. You then have to divide that by 24 to get the average temp. change per hour, which gives you an average of - 2.25 degrees an hour, because 54/24 is 2.25, and it is negative because the temperature is dropping.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
