A delivery truck drove 203 mi in 3.5 h. After unloading and loading new cargo, it traveled on another 243 mi for 4.5 h. What was
Firdavs [7]
The average speed of the truck is calculated by dividing the total distance traveled in a span of the total time given. From the given above, the total distance traveled is
                       total distance = 203 mi + 243 mi = 446 mi
and the total time it took for the whole trip is
                       total time = 3.5 h + 4.5 h = 8 h
The average speed is therefore,
                       average speed = 446 mi/8 h = 55.75 mi/h
Thus, the answer is letter A.

1. Which of these transformations are isometries? The diagrams are not drawn to scale.
lisov135 [29]

In math, an isometry is a congruent transformation in which the distance (or length) and the angle is preserved or remains the same even after the transformation.

The transformation can be translation, rotation, reflection, etc.

Let us not use this definition of isometry to answer our question, one at a time.

(I) In here, as we can see the distances 10 and 5 and the angle 43 degrees has been preserved. So, <u>this is an isometry.</u>

(II) In here, distances have been halved, so this is<u> not an isometry</u>, even though the angles have been preserved.

(III) In here, the corresponding distances and the angles have been preserved. So, <u>this is an isometry.</u>
