1. The average wind speed in Fresno, California in August is 6,8 miles per hour. What is this speed written as a mixed number?

below

Step-by-step explanation:

The decimal 6.8 is read as 6 and 8 tenths. So, it can be written as a mixed number 6810. Step 2: The mixed number has a whole number part 6 and a fractional part 8/10 which can be reduced to lowest terms as 45.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
