Answer:
V = 288
Step-by-step explanation:
To find the volume of the rectangular prism use this equation:
V = l*w*h
l = length
w = width
h = height
Now, lets assign all the variables to the numbers on the picture:
l = 12 ft
w = 4 ft
h = 6 ft
Plug these into the equation and solve
V = (12 ft)(4 ft) (6 ft)
V = 288
So, the volume of the rectangular prism is 288 .
Hope this helps!!
Step-by-step explanation:
I'll call the boxes at the bottom 1 through 6 from left to right.
1. The lines intersect
Answer: 2, 6
2. The lines are parallel
Answer: 3, 4
3. There is only one line
Answer: 1, 5
Answer:
Step-by-step explanation:
I would say the answer is 6
6 + 6 than times by two is 24
If "a" and "b" are two values of x-coordinate, and "m" is the midpoint between them, it means the distance from one end to the midpoint is the same as the distance from the midpoint to the other end
... a-m = m-b
When we add m+b to this equation, we get
... a+b = 2m
Solving for m gives
... m = (a+b)/2
This applies to y-coordinates as well. So ...
... The midpoint between (x1, y1) and (x2, y2) is ((x1+x2)/2, (y1+y2)/2)
_____
Jennifer had (x1, y1) = (-4, 10) and (x2, y2) = (-2, 6). So her calculation would be
... midpoint = ((-4-2)/2, (10+6)/2) = (-6/2, 16/2) = (-3, 8)
Brandon had (x1, y1) = (9, -4) and (x2, y2) = (-12, 8). So his calculation would be
... midpoint = ((9-12)/2, (-4+8)/2) = (-3/2, 4/2) = (-1.5, 2)
