Answer: three pieces.
The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.
Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.
1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.
Let x = total distance he covered
3x/4 by bus
1/2 . x/4 = x/8 by jogging
the remaining distance = x/8 by walking
thus x/8 = 800ft
x = 8 . 800 = 6400ft
Answer:
A = 3W² + W + 1/8πW²
Step-by-step explanation:
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
A = 3W² + W + 1/8πW²
