Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour
Hope this helps :)
Answer:
$6.48
Step-by-step explanation:
$1.50 × 4 = <u>$6.00</u>
for sales tax, $6.00 × 0.08 = <u>$0.48</u>
$6.00 + $0.48 = <u>$</u><u>6</u><u>.</u><u>4</u><u>8</u>
Answer:
rotation of 90 degrees counterclockwise centered at the origin
Step-by-step explanation:
Just look at one single point of A and what must happen to it to become the corresponding point in B.
Look at point (2, 1) in figure A. Draw a segment from (0, 0) to (2, 1).
The corresponding point in figure B to (2, 1) is (-1, 2). Now draw a segment from (0, 0) to (-1, 2). Look at the relationship between the two segments.
The segment (0, 0) to (2, 1) is perpendicular to the segment (0, 0) to (-1, 2).
The transformation is a rotation of 90 degrees counterclockwise centered at the origin.
