Answer:
25.5 mph
Step-by-step explanation:
So Bradley's speed can be modeled by the equation y=2x+40 where y=speed, x=time in hours after noon, and b=initial speed
So 12:15 is 15 minutes after noon, which is also 0.25 or 1/4 of an hour after noon. This is the x-value. Plug this into the equation to get his speed at 12:15
y=2(0.25)+40
y=0.5+40
y=40.5
So his speed was 40.5 at the time and since he was going 15 miles over the speed limit, the speed limit is 15 less than his speed
40.5 - 15 = 25.5
Answer:
10 and like 2/3 of a book
Step-by-step explanation:
8 books divided by 3 months would be 2 and 2/3 a month, and if they are both going the same rate each month, Jesse would be reading 10 and 2/3 books in 4 months.
Answer:
6 batches
Step-by-step explanation:
if he has 11 cups, and it takes 11/6 cups per batch, then he should be able to make 6 batches.
11 cups=66/6 cups
66/6 ÷ 11/6=6
Just use this formula
V= 1/2 bxhxl
