Answer:
51
Step-by-step explanation:
First you put all your numbers in order from least to greatest
Then you go from left to right crossing out the numbers
And which ever one is in the middle is the median.
Answer:
(x, y) = (6, 2)
Step-by-step explanation:
You solve for x and y by writing equations that reflect the relation applicable to the given geometry.
The diagonals of a parallelogram bisect each other. That means the halves of each diagonal are equal.
2x -4 = 4y . . . . . . down diagonal
x +4 = 7y -4 . . . . . up diagonal
__
We can subtract the first equation from 2 times the second equation to eliminate the x-variable.
2(x +4) -(2x -4) = 2(7y -4) -(4y)
2x +8 -2x +4 = 14y -8 -4y . . . . . . eliminate parentheses
12 = 10y -8 . . . . . . . . . . . . . . . . . collect terms
20 = 10y . . . . . . . . . . . . . . . . . . add 8
2 = y . . . . . . . . . . . . . . . . . . . . divide by 10
Substituting into the second equation gives ...
x +4 = 7(2) -4
x = 6 . . . . . . . . . . . . subtract 4
The values of x and y are (x, y) = (6, 2).
_____
The lengths of the diagonals are 20 and 16.
Answer:
im guessing its d
Step-by-step explanation:
First you need to find the Circumference
C = 2 pi r = 2 * 3.14 * 5.5 = 34.54
Arc measure / 360 = 7.7 / 34.54
Arc measure = 7.7 * 360 / 34.54
Arc measure = 80.25
Answer:
80.25 if you are using pi = 3.14
80.2 if you are using pi = 3.141592....
