Rosemary walks each week for exercise. let d represent the distance walked and h represent the number of hours spent walking.
last week: walked 18 miles in 6 hours
this week: d = 2.5h
which statement must be true?
a. this week, she walked a greater distance.
b. last week, she walked a greater distance
c. this week, she walked at a faster pace.
d. last week, she walked at a faster pace
explain the answer

Last week, she walked a greater distance

Step-by-step explanation:

Rosemary walks each week for exercise. Let d represent the distance walked and h represent the number of hours spent walking.

Last week: walked 18 miles in 6 hours

Rosemary walked (18/6) = 3 miles per hour

This week: d = 2.5h

This week she walked 2.5 miles per hour

last week she walked 3 miles per hour that is greater than 2.5 miles per hour

So , Last week, she walked a greater distance

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
