The volume of a rectangular prism is length times width times height, the answer is 40 inches cubed for Mindys prism and 40 centimeters cubed for MAtts prism.
Answer:
see below
Step-by-step explanation:
To find the coordinates of the midpoints, add the x's and divide by 2 and add the y's and divide by 2.
The coordinates of D, the midpoint of AB, (1+3)/2 will be the x-coordinate and (4+0)/2 will be the y-coordinate.
D (2,2)
You could also see this on a graph, see image.
E, the midpoint of AC has the x-coordinate (1+-3)/2, which is -1 and y-coordinate (4+-2)/2 which is 1.
E is (-1,1)
Then we are able to calculate the slope of DE and BC.
To calculate slope, subtract the y's and put that on top of a fraction and subtract x's and put that on the bottom of a fraction. If the slopes are the same the segment are parallel.
Slope of DE:
(2-1)/(2--1)
= 1/3
Slope of BC:
(0--2)/(3--3)
=2/6
=1/3
The slopes of BC and DE are equal, so the segments are parallel.
(Alternatively, you could show that Triangle ABC and Triangle ADE are similar. Then find the segments parallel because corresponding angles are congruent.)
Answer:
20
Step-by-step explanation:
There are 15 in 600. There would then be 2.5 for 100, but we round that to 3. There are 1 per every 40 in 200, so we have 19. We have 20 left, and could expect at least one, so it is 20. :)
The slope of the line is the line of best fit, and it shows that even though all the points are different, they are all in the same area and they are increasing
