You would need 438.45 inches of wrapping paper to cover the triangular prism completely. But since you can’t really cut the paper to that exact decimal you would round to 439 inches. Don’t forget to cube your answer since it’s area. Final answer should look like 429in.2
Answer:
13 by 20 inches
Step-by-step explanation:
Represent the quantities as follows:
P = 2W + 2L
L = W + 7
Then P = 2W + 2(W + 7), or P = 4W + 14
and this formula has the value 66 inches.
Thus, P = 66 inches = 4W + 14 inches, or
52 inches = 4W
Dividing both sides by 4, we get W = 13 inches.
The width is 13 inches and the length is (13 + 7) inches, or 20 inches.
Answer:
239
Step-by-step explanation:
Part A
The first thing we must do in this case is to hide the slopes of each line.
line m:
m = (- 4-3) / (0 - (- 4))
m = -7 / 4
Line n:
n = (- 2-2) / (3-1)
n= -4 / 2
n = -2
Answer:
Lines m and n are not parallel because their slopes are different.
Part B:
We look for the slope of the K line:
k = (1 - (- 3)) / (4 - (- 3))
k = 4/7
We observe that it is true that:
k = -1 / m
Answer:
The lines are perpendicular.
