4(5) or 4x5=20
20-12=8 so the answer is 8
Answer:
Nancy's heart rate is higher than Lee's heart rate.
Step-by-step explanation:
Equation for the heart beats of Lee is,
y = 1.2x
And the heart beats of Nancy is represented by the graph.
Higher the slope of the line = Faster the hear rate.
Slope of line represented by y = 1.2x,
m = 1.2
Similarly, slope of the line given in the graph = 
= 
= 1.25
Since, slope of the line representing Nancy's heart rate is greater than slope of the line representing Lee's heart rate.
Therefore, Nancy's heart rate is faster than Lee's heart rate.
B.) <span>counterclockwise 270°
We know, In order to change the nature of rotation, we have to subtract the angle from 360 degrees.
So, 360 - 90 = 270 [ & don't forget to change clockwise to counterclockwise ]
Hope this helps!</span>
Answer:
It is an iscoceles trapezoid but, one corner is unnoticeably off by 1. I think it would still be an iscoceles trapezoid.
