Quadrilateral ABCD has vertices AC-3.6), B(6,0), C(9. -9), and D(0, -3). Prove that ABCD is a) a parallelogram
Answers
9514 1404 393
Explanation:
The quadrilateral will be a parallelogram if the diagonals bisect each other. That will be the case if the sums of their end-point coordinates are the same.
A + C = (-3, 6) +(9, -9) = (6, -3)
B + D = (6, 0) +(0, -3) = (6, -3)
Both diagonals have their midpoint at (3, -1.5), so the diagonals are mutual bisectors. The figure ABCD must be a parallelogram.
___
The midpoint of AC is (A+C)/2 = (6, -3)/2 = (3, -1.5).
A, B & C lie on a straight line. D, C & E lie on a different straight line. Angle y = 117° and angle z = 63°. Work out x
Answers
Consider the below figure attached with this question.
Given:
A, B & C lie on a straight line. D, C & E lie on a different straight line.
[tex]\angle y=117^\circ,\angle z=63^\circ[/tex]
To find:
The value of x.
Solution:
A, B & C lie on a straight line.
[tex]m\angle ABD+m\angle DBC=180^\circ[/tex] (Linear pair)
[tex]y+m\angle DBC=180^\circ[/tex]
[tex]m\angle DBC=180^\circ-y[/tex]
According to the exterior angle theorem, the measure of an exterior angle of a triangle is equal to the sum of two opposite interior angles.
[tex]m\angle DBC+m\angle BDC=m\angle BCE[/tex] (Exterior angle theorem)
[tex]180^\circ-y+z=x[/tex]
[tex]180^\circ-117^\circ +63^\circ =x[/tex]
[tex]126^\circ =x[/tex]
Therefore, the value of x is 126 degrees.

Step-by-step explanation:
I think this is an arithmetic series, so
Sn = 26/2[2(1) + (26 - 1)2]
Sn = 13[2 + 50]
Sn = 13[52]
Sn = 676

A = 1
B = 3
C = 5
D = 7
...
Z = 51

You need to translate all the points to the right 3 and up 6
Therefore, you are going to use this formula:
(x,y) ⇾ (x + 3, y + 6)
This is the same format as the previous problem, if you have noticed.
Using this, plug in each coordinate, starting with P (5, -1)
(5, -1) ⇾ ( 5 + 3, -1 + 6)
(5, -1) ⇾ ( 8, 5 )
P[tex]^{1}[/tex] = (8, 5)
Now point Q, (0, 8)
(0, 8) ⇾ (0 + 3, 8 + 6)
(0, 8) ⇾ ( 3, 14 )
Q[tex]^{1}[/tex] = (3, 14)
And last but not least, the point R, (7, 5)
(7, 5) ⇾ (7 + 3, 5 + 6)
(7, 5) ⇾ ( 10, 11 )
R[tex]^{1}[/tex] = (10, 11)
Therefore, P[tex]^{1}[/tex] = (8, 5), Q[tex]^{1}[/tex] = (3, 14), R[tex]^{1}[/tex] = (10, 11) is your answer. This is the 4th option or D.
Hope this for you to understand this a bit more! =D

Determine the volume of the rectangular prism.
Answers
Answer:
50 ft³Step-by-step explanation:
We know the formula for a rectangular prism is length × width × height
We also know all the sides so we can rewrite the formula replacing variables.
The length is 8, the width is 2[tex]\frac{1}{2}[/tex] and the height is 2[tex]\frac{1}{2}[/tex]
8 × 2[tex]\frac{1}{2}[/tex] × 2[tex]\frac{1}{2}[/tex]
Multiply which ever way is easy for you. I am just multiplying from left to right.
8 × 2[tex]\frac{1}{2}[/tex] = 20
20 × 2[tex]\frac{1}{2}[/tex] = 50
Now we get 50. Before we put our answer as 50, there are two more steps.
First we need to add the measurement unit which is feet or ft
We also need to add ³ since it is volume
50 ft³ is our final answer

Alex has a pile of 2p coins. She swapped exactly half of them for the same number of 10p coins.
Now she has £4.20
How much money did alex have initially?
Answers
Answer:
£8.4
Step-by-step explanation:
Since she swapped half and now has £4.20, then multiply that by 2
4.20 × 2 = 8.4
Alex initially had £8.4
The initial amount of Alex's 2p coins is £8.40
Let the initial worth of 2p coins = y
Half of y = y/2 The value of y/2 = £4.20The amount of money Alex had initially = yWe can then solve for the worth of y, which is the titla amount Alex had initially ;
y/2 = £4.20Multiply bith sides by 2 (y/2)×2 = £4.20 × 2 y = £8.40Therefore, the amount of money Alex had initially is £8.40
