Answer:

rate=1.28571428571.. (1.29) miles per minute, or 77.1428571429.. (77.14) mph

Step-by-step explanation:

<em>"use distance = rate time (d=rt) to find the number of miles per hour Etty must drive to go 45 miles in 35 minutes. ( remember time is written in hours?"</em>

distance=rate*time--- we know distance and time

45 mi= rate*35

rate=45/35

rate=1.28571428571 miles per minute, or 77.1428571429 mph

HELP!!!!
OverLord2011 [107]

Answer:

Step-by-step explanation:

You just need the distance formula here.  It's very simple to follow:

d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2    }

which, for us, looks like this:

d=\sqrt{(13-4)^2+(19-7)^2} and

d=\sqrt{9^2+12^2} and

d=\sqrt{81+144} and

d=\sqrt{225} so

d = 15

Mr. Smith offered to stay after school for an extra help session. The day after the
marissa [1.9K]

Answer:

132 students

Step-by-step explanation:

Mr Smith offers to take extra help session for students after school

The day after the help session 11 of his students were talking and found out that only 2 had stayed up for the help session

= 2/11

There were actually a total number of 24 students that stayed

We are asked to find the number of student that Mr Smith teaches throughout the day

Let x represent the number of students that were taught during the day

Therefore, the number of student that Mr Smith teaches during the day can be calculated as follows

2/11=24/x

Cross multiply both sides

2 × x = 24 × 11

2x= 264

Divide both sides by 2

2x/2=264/2

x= 132

Hence Mr Smith teaches 132 students during the day.
