Answer:
120 mph
Step-by-step explanation:
Distance = rate * time
D = 70 miles
t = 35 minutes
So that gives us:
70 mi = r(35 min)
Divide both sides by 35 min:
70/35 mi/min = r
simplify:
2 mi/min = r
If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:
2 * 60 = 120
120 mph = r
B & F Are The Only Two Points I Believe
Answer:
52,500
Step-by-step explanation:
We can convert the word problem into an equation:
1.36x= 71,400
x represents the number of people in the previous population
We divide both sides by 1.36
x=52,500
The previous population was 52,500!
Hope this helps!
Answer:
Q matches to a and P matches to b
Step-by-step explanation:
This is a volume question so we can use the volume of a cylinder to see which one corresponds to what. Volume of a cylinder is 
h. We know that the heights of the cylinders are the same since the diagram says so. We also know pi is the same since thats a constant. The only thing thats different is the radius (as you can see radius of P is bigger than Q). If the radius of P is bigger than Q and all the other things are the same (height is the same and pi is the same), then that automatically means that P has more volume than Q. More volume means more time to fill up. Since Q has less volume, it will take less time to fill up. So now we look at the graph. A shows that the height of water increases at a faster rate than that of B. This is because there is less volume in that container (less volume=less time to fill up). Therefore a matches to Q and therefore b matches to P
