Select the correct answer. William recorded data to determine the relationship between the time usage, x, and the percentage of charge left on his mobile phone, y. He graphed the data and drew the line of best fit. The equation of the line of best fit is y = -10x + 100. About how many hours will it take for the phone lose its charge completely?
A. about 5 hours
B. about 10 hours
C. about 20 hours
D. about 22 hours
E. about 24 hours

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
