Answer:
B, (11/2,-6)
Step-by-step explanation:
to get the midpoint of two endpoints, simply take the average of each corresponding coordinate
midpoint: ((Rx+Sx)/2,(Ry+Sy/2)).
((9+2/2),(-4+-8/2)) = (11/2,-12/2) = (11/2,-6)
the midpoint formula in general is : ((x+x1)/2),(y+y1)/2))
where x1 is the initial or first x coordinate, y1 is the initial or first y coordinate, x is the second, last, or final x coordinate. and y is the second, last, or final y coordinate.
Answer:
(c) 22
Step-by-step explanation:
The range of a set of data is found from a box and whisker plot by subtracting the lower whisker value from the upper whisker value:
range = 66 -44 = 22
The range in the number of pretzels is 22.
Answer:
Step-by-step explanation:
Becuase the moon is completely covering the sun for 7 minutes
1. The figure is a prism: V = lwh = (12.1)(5.3)(4.2) = 269.3 cu. cm.
2. The figure is also a prism but the base is triangular: V = 1/2*b*h*l = 1/2*(13)*(sqrt(3)/2*13)*24 = 1756.3 cu. yd.

Answer:
(6,3)
Step-by-step explanation:
y=2/3 x - 1
y=-1/2 x + 6
Since both equations are equal to y, we can set them equal
2/3 x - 1 =-1/2 x + 6
We have fractions, so I will multiply by 6 to clear the fractions
6(2/3 x - 1) =(-1/2 x + 6)6
Distribute
4x -6 = -3x +36
Add 3x to each side
4x+3x -6 = -3x+3x +36
7x -6 = 36
Add 6 to each side
7x-6+6 = 36+6
7x = 42
Divide each side by 7
7x/7 = 42/7
x =6
Now we need to find y
y =2/3x -1
y = 2/3(6) -1
y = 4-1
y=3
(6,3)
