The right answer to 1b is 1 5/8 and the right answer to number 1e is 1 3/7. The way I solved this was by starting out adding two fractions at a time...
1b). 5/8 + 5/8 + 3/8
5/8 + 5/8 = 10/8 or 1 1/4
10/8 + 3/8 = 13/8 or 1 5/8.
1e). 5/7 + 1/7 + 4/7
5/7 + 1/7 = 6/7
6/7 + 4/7 = 10/7 or 1 3/7

Answer: 87 feet
Step-by-step explanation:
The angle between the pilling is 60°
The adjacent side of the right angle is 150
So let the distance between the pilling be y, that is opposite side.
Opposite / adjacent = tan (60°)
y / 150 = tan (60)
y × tan (60°) = 150
Divide both side by tan (60°)
y = 150 / tan (60°)
y = 150 / 1.7321
y = 87 feet
This cube has 6 faces, and all side lengths are equal.
The volume of a cube with sides of length L is given by L^3.
The problem says that the volume is 7^3, which means that each side is 7
The surface area of a cube of length L is 6*L^2. Since L = 7, the surface area is:
6*7^2 = 6*49 = 294 cm^2
C is the answer.........................
Well, a y-intercept is a the point on a graph where the x value equals 0, because the point sits exactly on the y-axis. In this case, the y-intercept would be (0, -9).
