Sue earns 20$ per hour. how much does she earn in 1/4 of an hour

The answer is 5$

Step-by-step explanation:

If he earns 20 dollars in 1 hour, then in 1/4 of an hour he will earn:

Since  1 hour=60 minutes

He earns 20 dollars in 60 minutes

There for he will earn (20/60)=1/3 dollars in one minute

1/4 of an hour=(1/4)×60=15 minutes

To get the amount he earns in 1/4 of an hour or 15 minutes,

=(Number of minutes in 1/4 of an hour)×Amount he earns in 1 minute)=(15×1/3)=5 dollars

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
