The x-coordinate of the midpoint is the average of the x-coordinates
of the ends.
The average of the ends is 1/2(-3+0) = -1.5 .
The y-coordinate of the midpoint is the average of the y-coordinates
of the ends.
The average of the ends is 1/2(-4+2) = -1
The midpoint of the segment is <em>(-1.5, -1)</em>.
Answer: B. Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.
Step-by-step explanation:
The options include:
A. Jessie earned a total commission of $800 in the first week and x dollars in the second week.
B. Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.
C. Jessie sold 1 car in the first week, earning $800, and x number of cars in the second week, earning a total commission of $1,200.
D. Jessie earned a commission of $800 on each car in the first week and $400 on each car in the second week, selling x number of cars each week.
The situation that could be described by this expression will be option B "Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car". This will be:
= (400 × 2) + 400(x)
= 800 + 400x
Given:
A figure of a triangular prism.
Height of triangular base =
yd
Base of triangular base = 4 yd
Height of prism = 4 yd.
To find:
The volume of the triangular prism.
Solution:
Volume of a triangular prism is:
...(i)
Where, B is the area of triangular base and h is the height of the prism.
Area of triangular base is:




Putting
and h=4 in (i), we get




The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.
