Each group take 5 mins to do 2yds
2 groups so in 5 mins, 4 yards gets cleaned

how many yards per mile is 1760

2 miles=2*1760=3520

find how many times of the 5 mins they have to clean (remember 4 yds per 5 mins)
3520/4=880
that means 880 times 5mins=4400mins=73hrs and 20mins

Answer:

10 2/15 hours

Step-by-step explanation:

If we have a candle that is 11 2/5 inches tall

It burns 1 1/8 inches per hour.  We need to divide to see how long the candle will last

11 2/5 ÷ 1 1/8

I will convert the mixed numbers to improper fractions

11 2/5 = (5*11+2)/5 = 57/5

1 1/8 = (8*1+1)/8 = 9/8

57/5 ÷ 9/8

Copy dot flip

57/5 * 8/9

456/45

Now we change it back to a mixed number

45 goes into 456  10 times with 6 left over

10 6/45

This simplifies to 10 2/15

A student was asked to find the slope of the line through the points (4,8) and (-3,5). His answer, <img src="https://tex.z-dn.ne
evablogger [386]

Answer:

m=\frac{-3}{-7}

Step-by-step explanation:

Given the following question:

Point A = (4, 8) = (x1, y1)
Point B = (-3, 5) = (x2, y2)

In order to find the slope any two points given we use the formula to find slope or rise/run.

m=\frac{y2-y1}{x2-x1}
m=\frac{5-8}{-3-4} =\frac{-3}{-7}
m=\frac{-3}{-7}

The reason why the students answer is incorrect because he substituted incorrectly. More specifically the run part of the formula for slope. The formula for slope goes x2 - x1 which means it should be -3 - 4, not -4 - 3, which will give you the answer -7.

Hope this helps.
