(intro) Slope is change in y divided by change in x (axes). Here, the y axis is depth and the x axis is hours. So, the slope is change in depth between any two points, divided by the change in hours between the same points. The slope of this line is half a foot depth divided by 2 hours.
a) So, the slope is 0.5 / 2 = 0.25, or 1/4.
b) The graph shows a constant rate of change because the line is straight (it increases at the same speed. If the line was curving, it would not be a constant rate of change).
c) Yes, because the line has a constant rate of change now.
Becky =B
Min =M
B =2M and B + M = 42.
(2M) + M= 3M = 42 and so M=42/3=14.
B = 2M so it's 14*2=28
Becky scored 28 points.
Answer:
After 7 hours Tevin will catch Enrique
Step-by-step explanation:
We have given speed of Enrique is 20 mph
Tevin left traveling after 2 hours of Enrique
Speed of Tevin is 28 mph
When Tevin catches Enrique will cover same distance
Let Enrique is traveling for t hours
Then Tevin will travel for t-2 hours
We know that distance = speed × time
So 
t = 7 hours
So after 7 hours Tevin will catch Enrique
Answer:
h*h=10*10+3*3
h*h=100+9
h*h=109
square root of h=square root of 109
h=10.44
Volume of a cylinder=πr^2h
=πx2.5x2.5x12
=πx75
=235.62 cubic inches
