Keiko is walking. The number of calories she has burned varies directly with the number of minutes she has walked. See the graph below.

How many minutes does Keiko walk per calorie burned?

5

Step-by-step explanation:

try 5 it should work

5 calories per minute.

The graph shows a proportional relationship where every 10 minutes, 50 calories are burned. Since it is proportional, we can divide 50 by 10 and get 5.

the answer is 5636.7

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
