astraxan [27]

Answer:

in six hours it would be $34.25

Step-by-step explanation:

The computation of the total cost for 6 hours is shown below:

For one hour it would be $8.50

For two hours

= $13.65 - $8.50

= $5.15

For three hours

= $18.80 - $13.65

= $5.15

For four hours

= $23.95 - $18.80

= $5.15

For five hours

= $23.95 + $5.15

= $29.10

For six hours

= $29.10 + $5.15

= $34.25

Hence, in six hours it would be $34.25

I’m very confused on this, what’s the answer? And if possible can I also have an explanation? Thank you ^^
Tatiana [17]

Answer:

58 sq in

Step-by-step explanation:

You need to cut the drawing into pieces in your mind first. Starting at the bottom, the triangle's area is 1/2bh, so it is 1/2 x 8 x 6 = 24 sq in.

Now I would cut the top triangle off, and do 1/2bh, and the height is 3 as you can tell from the right measurement of 8 minus the left measurement of 5.

1/2 x 3 x 6 = 9 sq in.

Now you have a trapezoid left. It's area is (b1 + b2)/2 x h. Base 1 (the top) is 6 and base 2 (the bottom) is 4. 6 + 4 / 2 = 5. 5 x 5 = 25 sq in.

Now just add them up: 24 + 9 + 25 = 58 sq in.
