Answer: 200 literes will be used in an hour
Step-by-step explanation:
1. 150 divided by 45 mins = 3.3 recurring
2. 3.3 recurring times 60 ( 60 mins in an hour) = 200
1=10
<span>2=20 </span>
<span>3=29 </span>
<span>4=37 </span>
<span>5=44 </span>
<span>6=50 </span>
<span>7=55 </span>
<span>8=59 </span>
<span>It would cost them $80 dollars to eat seperately so they saved $21.

Ok so we are gonna find the area or the rectangles on the object
Area of rectangle 1 = length x width
= 6 x 20
= 120 m square
Multiply the area of rectangle 1 by 2 because there are two same shaped rectangle.
120 x 2
=240 m square
Area of rectangle 2 = 30 x 6
= 180 m square
Multiply the area of rectangle 2 by 2 because there are two same shaped rectangle.
180 x 2
=360 m square
Area of rectangle 3 = 30 x 20
= 600 m square
Multiply the area of rectangle 3 by 2 because there are two same shaped rectangle.
600 x 2
=1200 m square
Then add all the area of the rectangles.
240 + 360 + 1200
= 1800 m square
Therefore the surface area is 1800 m square
Answer:
the first one
Step-by-step explanation:
The first equation is -5m+15
and the first one is 15-5m
Which is basically the same thing.
Glad to help
