The correct answer is -2 I just took the test.
He did not walk 1/2 a mile. Because it's a round-trip, it's technically 2 miles long. so, in the end, he did not walk 1/4 of the trip. Hope this helps :)
Answer:
<h2>174ft²</h2>
Step-by-step explanation:
Area of a Rectangle = L x W
L = 8
W = 6.5
Area of a Rectangle = 8 x 6.5 = 52
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 52 x 2 = 104
Area of a Rectangle = L x W
L = 8
W = 5
Area of a Rectangle = 8 x 5 = 40
Surface Area = Area of a Rectangle x Number of Rectangles
Surface Area = 40 x 1 = 40
Area of a Triangle = B x H x 1/2
B = 5
H= 6
Area of a Triangle = 5 x 6 x 1/2 = 15
Surface Area = Area of a Triangle x Number of Triangles
Surface Area = 15 x 2 = 30
Surface Area = Sum of Surface Areas =
104 + 40 + 30 = 174ft²
Answer:
there were 63,000L of water initially in the pool
Step-by-step explanation:
do 900L times the first 20 minutes to find out how much water was drained during the first 20 minutes and you get 18,000L drained
then, add 18,000L plus the rest of the 45,000L of water drained from the pool to get 63,000L of water intially in the pool
