how do i find the values of x and y that make the quadrilateral a parallelogram
The values of x and y that make the quadrilateral a parallelogram are, X = 25 & Y = 15
What is quadrilateral?Quadrilateral are the type of polygon who has 4 sides, on the basis of length and angle between sides we can further classify quadrilateral into following categories;
for example, Rectangle, Square, Parallelogram, Rhombus, Trapezium
Given that,
A parallelogram whose all the angles are,
(4x + 13)°, (4y + 7)°, (3x - 8)°, (5x - 12)°
It is known that,
Opposite Interior angles of parallelogram are equal
so,
⇒ (4x + 13) = (5x - 12)
⇒ x = 25
⇒ (4y + 7) = (3x - 8)
⇒ 4y + 7 = 75 - 8
⇒ 4y = 60
⇒ y = 15
Hence, the values of x and y are respectively 25, 15

triangle has vertices A( 0,0 ), B(2, 0) and C(0, 4). Angle ABC is transformed to angle A"B"C" by a rotation of 180 degrees clockwise about the origin, followed by a dilation with the origin as the center of dilation and scale factor of 3. find the coordinates of the vertices of angle A"B"C" and state whether the two triangles are similar or congruent.
Step-by-step explanation:
The pre-image points are A( 0,0 ), B(2, 0) and C(0, 4). The question is asking you to rotate the traingle 180°. Each rotation has its rules. For 180° rotation our rule is (x,y) → (-x,-y). Let's apply that to our points:
A( 0,0 ), → (0,0)
B(2, 0) → (-2,0)
and C(0, 4). → (0,-4)
Now we dilate our point ( remember the order in which you do transformation is important. Since it saids the rotation is followed that means the dilation is done second)
Our scale factor is 3. Remember when our scale factor is more than one our shape gets bigger. So our rule is (x,y) → (kx,ky). Let's apply our scale factor to all our points:
(0,0) → (0,0)
(-2,0)→( -6,0)
(0,-4) → (0,-12)
The answer is
A' (0,0) B' (-6,0) C' (0,-12)
The triangles will be similar not congruent. Remember congruent triangles have the same angles and same sizes. Similar angles have the same angles BUT different sizes. Every transformation produces congruent angles except for dilations.
A bicycle shop is selling $500 bikes at 10% off. If the sales tax is 7%, how much will the bike cost?
Answer:
The bike will cost $481.50
because
10% off of 500 is 50
so 500 - 50 = 450
Now include the sales tax which is
450 * 0.07 = 31.5
Now add the two totals to get
$481.50

20% of the tickets sold at a school carnival were early-admission tickets. If the school sold 30 tickets in all, how many early-admission tickets did it sellz?
Answer:
6 early-admission tickets.
Step-by-step explanation:
20% / 100 = 0.2 ; Dividing a percentage by 100 will give you its actual value, instead of the percentage.
0.20 x 30 tickets = 6 early-admission tickets. ; What we're saying here is that since 0.20 and 20% are the same, we can figure out what 20% of 30 is, which is 6.

Answer:
Step-by-step explanation:
the Pythagorean theorem is
c is the hypotenuse which is the side opposite of the right angle
plug the numbers into the Pythagorean theorem
[tex]x^2+(\sqrt{26})^2=13^2[/tex]
when squaring a square root, just take the number in the radical and get rid of the radical
[tex]x^2+26=169[/tex]
subtract 26 from both sides
[tex]x^2=[/tex][tex]143[/tex]
find the square root of 143
143 is prime so it can just be written as
[tex]x=\sqrt{143}[/tex]

x + y = -7
y + z = -7
x - z = 0
Answer:
Step-by-step explanation:If we add the first and second equations, we will eliminate both the x and the y.
(2x + y + z) + (2x - y - z) = (3) + (9)
2x + y + z + 2x - y - z = 3 + 9
4x = 12
x = 3
So, x must equal 3.
Now, if we put 3 into each equation, we have the following equations:
6 + y + z = 3
6 - y - z = 9
3 + y - z = 0
Now, we can move all the numbers to the right side:
y + z = -3
-y - z = 3
y - z = -3
Now, we can try to eliminate another variable. If we add the second two equations, we can eliminate y.
(-y - z) + (y - z) = (3) + (-3)
-y -z + y - z = 0
-2z = 0
z = 0 (because, if we divide both sides by -2 to isolate z, 0/[-2] = 0)
So, now we have x = 3 & z = 0.
Now, pick any of the original equations and plug these values of x & z in, and you will get y.
2x + y + z = 3
2(3) + y + 0 = 3
6 + y + 0 = 3
6 + y = 3
y = -3
So, now we have x = 3, y = -3, & z = 0.
These are the only x, y, and z values that work for all 3 equations

Noah and Lin are making paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
height (h)=
radius (r)=
Answer:
So, The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
Step-by-step explanation:
P.S - The exact ques is -
As we know that Volume of cone , V = [tex]\frac{1}{3}\pi r^{2}h[/tex]
As given,
V = [tex]9\pi[/tex]
⇒[tex]\frac{1}{3}\pi r^{2}h = 9\pi \\ \frac{1}{3} r^{2}h = 9 \\r^{2}h = 27[/tex]
So,
The possible values of h and r are
1. r = 3 , h = 3
2. r = 1, h = 27
3. r = 2, h = 6.75
In Case I-
When r = 3, h = 3
(3)² ×3 = 9×3 = 27
Satisfied
Case II-
r = 1, h = 27
(1)²×27 = 1×27 = 27
Satisfied
Case III-
r = 2, h = 6.75
(2)²×6.75 = 4×6.75 = 27
Satisfied
If the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.
What is the volume of the cone?The volume of the cone is the volume occupied by the cone. It is given by the formula,
[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h[/tex]
where r is the radius of the base, and h is the height of the cone.
Now, as it is given that cones need to hold 9 cubic inches of popcorn. therefore, the volume of the cone can be written as,
[tex]\text{Volume of the cone}= \dfrac{1}{3} \pi r^2h\\\\9 \times 3 = \pi r^2h\\\\\dfrac{9 \times 3}{\pi}=r^2 h\\\\8.5943 = r^2 h[/tex]
Thus, the product of the square of the radius and the height of the cone should be such that the result is 8.5943.
Now, let the radius of the cone be 2 inches, therefore, the height of the cone is,
[tex]8.5943 = r^2 h\\\\8.5943 = (2^2) h\\\\h = 2.1485\rm\ in[/tex]
Hence, if the radius of the base of the cone is 2 inches then the height of the cone should be 2.1485 inches.

(e) A cable customer feels that the monthly cost of cable TV increased the most. A grocery customer feels that the cost of a dozen eggs increased the most. Is it possible for both customers to be correct? Explain your response in one or two complete sentences.
Answer and explanation:
Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%
Cable TV cost increased by 21.818% of original cost
Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%
Dozen of eggs cost increased by 22.636% of original cost
Therefore both customers can't be correct, cost of a dozen of eggs increased the most.

Can someone help me find out what’s the nth formula equation
An example is where it should look like 6•5^n-1
Or 7n-4 (that’s an example) if it’s correct I’ll mark u brainiest.
Part (a)
This sequence is arithmetic because we are adding 4 to each term to get the next term. Nice work on getting the correct answer here.
To get the nth term of an arithmetic sequence, we'll use the formula below
an = a + d(n-1)
In this case, a = 14 is the first term and d = 4 is the common difference
So we have these steps
an = a + d(n-1)
an = 14 + 4(n-1)
an = 14 + 4n - 4
an = 4n + 10
Answer: 4n + 10
============================================
Part (b)
This sequence is geometric since we multiply each term by 4
The common ratio is r = 4 and the start term is a = 2.
So the nth term is....
an = a*(r)^(n-1)
an = 2*(4)^(n-1)
Answer: 2*(4)^(n-1)
