Answer:
Mme Q spent more time answering emails from students by 10 minutes
Step-by-step explanation:
Here we have
Time spent by Mme Q in answering mails on Friday given by
5/6 Hour = 50 minutes and
7/12 Hour = 35 minutes
Total time spent on Friday = 85 Minutes or
5/6 + 7/12 = 17/12 Hours
Time spent by Mme F in answering mails on Friday given by
1/2 Hour = 30 minutes and
3/4 Hour = 45 minutes
Total time spent on Friday by Mme F = 75 Minutes or
1/2 + 3/4 = 5/4 Hours
Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.
EXPLANATION
Price of shoes = $5.50

Answer:
here you go
Step-by-step explanation:
1 is = 2 is >
As you can see in the picture, all the points lie on the same line, so they are collinear. The line follows an equation with the general form of:
y = mx + b
where m and b are the constants
The b parameter is the y-intercept. This is the point at which the line intersects the y-axis. From the graph, b = 0. The other constant is the slope m. You can choose any two points, the answer would just be the same.
m = (y₂ - y₁)/(x₂ - x₁)
Suppose point 1 is (2,1) and point 2 is (3,1.5).
m = (1.5 - 1)/(3 - 2) = 1/2 or 0.5
Therefore, the answer is either 0 or 0.5. From the choices, the answer would be letter C.
