PLZ HELP -geometry- Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(1,3), H(4,3), J(5,1), and K(2,1).
The coordinates are ( , ).
Answer:
The coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].
Step-by-step explanation:
Diagonals are represented by line segments GJ and KH. Since quadrilateral is a parallelogram, then coordinates of the intersection are located at midpoint of each diagonal ([tex]M(x,y)[/tex]). That is:
[tex]M(x,y) = G(x,y) + \frac{1}{2}\cdot \overrightarrow {GJ}[/tex]
[tex]M(x,y) = G(x,y) +\frac{1}{2}\cdot [J(x,y)-G(x,y)][/tex] (1)
If we know that [tex]G(x,y) = (1,3)[/tex] and [tex]J(x,y) = (5,1)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:
[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot [(5,1)-(1,3)][/tex]
[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot (4,-2)[/tex]
[tex]M(x,y) = (1,3) +(2,-1)[/tex]
[tex]M(x,y) = (3,2)[/tex]
There is another form:
[tex]M(x,y) = K(x,y) +\frac{1}{2}\cdot \overrightarrow{KH}[/tex]
[tex]M(x,y) = K(x,y) + \frac{1}{2}\cdot [H(x,y)-K(x,y)][/tex] (2)
If we know that [tex]K(x,y) = (2, 1)[/tex] and [tex]H(x,y) = (4,3)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:
[tex]M(x,y) = (2,1) + \frac{1}{2}\cdot [(4,3)-(2,1)][/tex]
[tex]M(x,y) = (2,1) + \frac{1}{2} \cdot (2,2)[/tex]
[tex]M(x,y) = (2,1) + (1,1)[/tex]
[tex]M(x,y) = (3,2)[/tex]
Therefore, the coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].

Evaluate the expression 5+(-3x)for the given x-values. A. X=3. B. X=1/3. C.X=-3
Answer:
a. [tex]5 + (-3x) = -4[/tex]
b. [tex]5 + (-3x) = 4[/tex]
c. [tex]5 + (-3x) = 14[/tex]
Step-by-step explanation:
Given
[tex]5 + (-3x)[/tex]
Required
Evaluate
(a) x = 3
[tex]5 + (-3x) = 5 + (-3*3)[/tex]
[tex]5 + (-3x) = 5 + (-9)[/tex]
Remove bracket
[tex]5 + (-3x) = 5 -9[/tex]
[tex]5 + (-3x) = -4[/tex]
(b) x = 1/3
[tex]5 + (-3x) = 5 + (-3*1/3)[/tex]
[tex]5 + (-3x) = 5 + (-1)[/tex]
Remove bracket
[tex]5 + (-3x) = 5 -1[/tex]
[tex]5 + (-3x) = 4[/tex]
(c) x = -3
[tex]5 + (-3x) = 5 + (-3*-3)[/tex]
[tex]5 + (-3x) = 5 + (9)[/tex]
[tex]5 + (-3x) = 14[/tex]

Ben has 6 children. He gives each child 2 - pies. How many pies does he neer).
Answer:
12 pies
Step-by-step explanation:
No. of children = 6
No. of pies given to each child = 2
Total no. of pies needed by Ben;
6 x 2 = 12
[tex] \huge \underline \pink {answer}[/tex]
number of children Ben has = 6
number of pies given to each child = 2
number of pies Ben need = 6×2 = 12
hence Ben needs 12 pies..

Answer:
[tex]\frac{7}{8}[/tex]
Step-by-step explanation:
Find the average by adding the 2 fractions and dividing the sum by 2
[tex]\frac{1}{2}[/tex] + 1 [tex]\frac{1}{4}[/tex]
= [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{2}{4}[/tex] + [tex]\frac{5}{4}[/tex]
= [tex]\frac{7}{4}[/tex]
Then
[tex]\frac{7}{4}[/tex] ÷ 2
= [tex]\frac{7}{4}[/tex] × [tex]\frac{1}{2}[/tex]
= [tex]\frac{7}{8}[/tex]
Write down the value of angle y, giving a reason for your answer
Y=
Other angle given is 67 degrees
Answer:
y would be 67 as well.
Step-by-step explanation:
they are alternate interior angles. hope it helps
In part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.
What is the triangle?In terms of geometry, the triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
Part(a)
We have a triangle shown in the picture.
The two lengths of a triangle are equal.
The angle opposite to the sides will be equal.
As we know,
The triangle's interior angles add up to 180°.
180 = 55 + 55 + x
x = 180 - 110
x = 70 degrees
In part (b)
There are two parallel lines shown in the picture.
The angle y will be the same as 67 degrees because two parallel lines are cut by a transversal line.
Thus, in the part (a) the missing angle of a triangle is 70 degrees and in part (b) the missing angle is 67 degrees.

convert 225° to a radian measure in lowest terms
Answer:
To convert degrees to radians, multiply by π180° π 180 ° , since a full circle is 360° 360 ° or 2π 2 π radians. 225°⋅π180° 225 ° ⋅ π 180 ° radians.

The options are 19,200 , 17,600, 15,200, 12,000 I give crown ;-)
Answer:
15,200 ft^2
Step-by-step explanation:
The shape of the playground can be thought of as two rectangles.
The rectangle on the left side measures 2.5 inches by 3 inches.
The rectangle on the right side has a width of 1 inch. The length along the bottom side measures 4.5 inches - 2.5 inches = 2 inches
total area = LW + lw
total area = 3 in. * 2.5 in. + 2 in. * 1 in.
total area = 7.5 in. + 2 in.
total area= 9.5 in.^2
Now we need to convert to the actual area from the scale drawing area.
1 in. = 40 ft
9.5 in.^2 * (40 ft / in.) * (40 ft / in.) = 15,200 ft^2
Answer: 15,200 ft^2

A car travel 140 miles in 3 hours (with a constant speed). How far can it travel in 7 hours (with the same speed)?
Answer:
326.666miles
Step-by-step explanation:
v=distance/time (v=d/t)
d=140 miles
t=3hrs
v=d/t, v=140/3, v= 46.666mph
v=46.666mph
t=7hrs
d=?
v=d/t, d=vt, d=46.666mph x 7hrs, d= 326.666miles
