Answer:
The coordinates of D are (8,3)
Step-by-step explanation:
We have quadrilateral ABCD being a parallelogram with coordinates A(3,2), B(5,4), C(10,5), and D(a,b).
We want to find the coordinates of D.
Since ABCD is a parallelogram, the diagonals AC and BD bisects each other.
The midpoint of AC is (13/2,7/2).
This is also the midpoint of BD.
By the midpoint rule:
This implies that:
Similarly,
The coordinates of D are (8,3)
16a.) π
16b.) = 7 ÷ 15
Put (7 ÷ 15) in your calculater to get 0.4666667
That multiplied by 100 and rounded to the nearest whole percent is
47%
17a.) 24 + 16 + 14 = 54
17b.) 8 ÷ 27 = 0.296
0.296 × 100 = 29.6
Rounded to the nearest whole number is 27%
