The smallest number of schools would be if all the schools entered the max amount of teams they could. So we first just want to say as many schools as possible entered 4 teams.
So here just divide 247 by 4.
That would be 61 R3
So we say that 61 schools entered with four teams. Now there are 3 teams extra. We can assign these to just one school, because a school can enter 3 teams. So then the total amount of schools entered in the XYZ contest, in this case, would be 62.
Find minutes per mile by dividing time by distance:
45 minutes / 6 miles = 7.5 minutes per mile
Now multiply his speed by each distance:
7.5 x 9 = 67.5 minutes
7.5 x 15 = 112.5 minutes
Now subtract the two:
112.5 - 67.5 = 45 minutes more
Answer:
A) 3hrs
Step-by-step explanation:
Fission is the action of dividing or splitting something into two or more parts.
So, we're going to continuously multiply our answers by 2 until we get 360
10 x 2 = 20 30min
20 x 2 = 40 1hr
40 x 2 = 80 1hr 30min
80 x 2 = 160 2hrs
160 x 2 = 320 2hrs 30min
320 x 2 = 630 3hrs
1.5 is the correct answer :)
Answer:
x = 1
Step-by-step explanation:
If you plug in 1 in both equations you will get 3 as your answer as it is the intersection of those two functions.
