To find the percent. A trick I learned in middle school was Dr. P
To turn a decimal to a percent and a percent to decimal... (look at picture)
Using that trick...
All you do is multiply $287.69 by .20
Which gives you $57.538 so you can round to either...
$57.54
Or
$57.50
Or
$58
And one of those are your answer!
Answer:
The expression is not factorable with rational numbers
Step-by-step explanation:
Let points R, S, T be the midpoints of segments AC, AB, and CB.
Triangle midline theorem states that the line segment connecting the midpoints of two sides of a triangle is parallel to and half the length of the third side.
Thus, the midline RS (where R is a midpoint of AC and S is the midpoint of AB) is parallel to BC and is half the length of the side BC:

Answer: correct choice is A
