We are given with an 18 student class that is working a project worked by pairs. Each pair works on a project. In this case, there are 9 teams of 2 individuals working on a single project. Hence for a year or school year, there are 9 projects accomplished each time.
Answer: D: 17.3
Step-by-step explanation:
I believe its D because the house and the ground is a 90 degree angle, and at 60 degree angle is a 20 foot ladder. alright then 90 plus 60 = 150 degrees.
then add the twenty foot ladder with each choice for the answer:
A: 20 + 6.1 = 26.1
B: 20 + 10.0 = 30
C: 20 + 14.1 = 34.1
D: 20 + 17.3 = 37.3
The answer would be D because it is the closer number to 150. Because it says " which is the closest height up the house the ladder reaches?" The answer is D the closest number. I HOPE THIS HELPS YOU! =D

Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y =
x - 4 → with m = 
y = x + 1 → with m = 1
y = -
x - 3 → with m = - 
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = -
x - 3 are Perpendicular since 2 × -
= - 1
Answer:
B.
Step-by-step explanation:
We see (-10) repeating six times. This means the product would be 6(-10). To simplify this, 6 × (-10) = -60.
