Triangle MNO is dilated to form new triangle PQR. If angle
is congruent to angle R. what other information will prove that the two triangles are similar by the AA similarity postulate?
Side ON is congruent to side RQ.
Angle Nis congruent to angle
Side MN is congruent to side PQ.
Angle M is congruent to angle Q.
Please help
Answers
Answer:
Angle N is congruent to Angle Q.Step-by-step explanation:
If triangles MNO and PQR are similar, then the corresponding sides are propotional and the corresponding angles are congruent.
Angle M corresponds to Angle P.Angle N corresponds to Angle Q.Angle O corresponds to Angle R.So, we know by gvein that angles O and R are congruent. We only need another angle congruence to use the AA postulate of similarity.
Therefore, the right answer is the second choices, because Angle N must be congruent to Angle Q.
Answer: B: Angle N isn’t congruent to angle Q
Step-by-step explanation: You have to follow the letters MNO and PQR. We know O is congruent to R to get another angle we would use Angle N and Q because of the order since Angle M and angle Q aren’t in the same order and we’re not dealing with sides only Angles.

Answers
The value of x in the model that makes the equation true is: b. x = 2.25
We can find the value of x that makes the equation true by applying our knowledge of how to model equations.
From the image given:
On your left, we have -x, in three places which can be translated to as: [tex]3 \times -x = -3x[/tex]On the left also, we are given [tex]10 \times 1 = 10[/tex]We can model the left side as:[tex]-3x + 10[/tex]
On your right, we have x in five places which can be translated to as: [tex]5 \times x = 5x[/tex]On the right also, we are given [tex]8 \times -1 = -8[/tex]We can model the left side as:[tex]5x - 8[/tex]
The equation would be:[tex]-3x + 10 = 5x - 8[/tex]
Solve the equation for the value of x. Collect like terms.[tex]-3x - 5x = - 8 - 10\\\\-8x = -18[/tex]
Divide both sides by -8[tex]x = \frac{-18}{-8} \\\\x = 2.25[/tex]
Therefore, the value of x in the model that makes the equation true is: b. x = 2.25

Where does the point T(5,-2)T(5,−2)T, left parenthesis, 5, comma, minus, 2, right parenthesis lie?
Answers
Answer:
Point T is on the circle
Step-by-step explanation:
To check where the point lies, we need to find its distance to the center of the circle.
The distance between two points (x1, y1) and (x2, y2) is given by:
[tex]distance = \sqrt[2]{(x2 - x1)^{2} + (y2 - y1)^{2}}[/tex]
If the first point is O(0,0) and the second is T(5, -2), we have:
[tex]distance = \sqrt[2]{(5 - 0)^{2} + (-2 - 0)^{2}}[/tex]
[tex]distance = \sqrt{29}[/tex]
The distance between the points is equal the radius of the circle, that means the point T is on the circle.

Write the equation of the line with the following characteristics. Parallel to y=7x+2 through the point (0,0)
Answers
Answer:
y = 7x - 5
Step-by-step explanation:
y = 7x+2 we see the gradient is 7 (x 0) + 2 = Since the line is parallel to y= 7x +2
The new line has a slope of 7 + 2 as the intercept at y.
y - 0 = 7 ( x - 0)
y - 1/7 = x - 0
y = 7x - 5
As 7 -5 = 2
Hence equation of line becomes y=7x.
What is Equation of line?You must ensure that both equations have the same slope in order to find an equation for a line that is parallel to another. The m reflects your slope value in the general equation of a line, y=mx+b.
How to solve?Now given line y=7x+2 ,this line is parallel to another line which passes through origin(0,0)
Hence putting 0,0 in general equation to find equation of parallel line
⇒y=mx+c
⇒0=m(0)+c
⇒0=c
where m=7 as parallel lines have same slope.
Hence equation of line becomes y=7x.

Calculate the interquartike range (IQR=Q3-Q1) of the following data 17, 18, 18, 19, 20, 21, 21, 23, 25
Answers
Answer:
4
Step-by-step explanation:
20 is the median
so before and after 20 is the Q3 and Q1
Q1 is 18
Q3 is 22
22 minus 18
The Interquartile range, IQR of the numbers is 4
The process of calculating the above Interquartile Range, IQR is as follows;
The given numbers in the data set are;
17, 18, 18, 19, 20, 21, 21, 23, 25
The required information;
Calculate the inter quartile range IQR = Q₃ - Q₁
The method;
The numbers in the data set are to be arranged in increasing order from smallest to largest number to give;
17, 18, 18, 19, 20, 21, 21, 23, 25 (The numbers were already arranged)
The values of first quartile, Q₁, and the third quartile, Q₃ are then found as follows;
The first quartile, Q₁ = The (n + 1)/4 th term
The third quartile, Q₃ = The 3·(n + 1)/4 th term
Where;
n = The number count in the data set = 9
Therefore:
Q₁ = The (9 + 1)/4 = The 2.5 th term = 18 + (18 - 18) × 0.5 = 18
Q₃ = The 3 × (9 + 1)/4 th term = 7.5 th term = 21 + (23 - 21) × 0.5 = 22
IQR = Q₃ - Q₁
Therefore;
IQR = 22 - 18 = 4
The Interquartile Range, IQR = 4

No, the distance from (3, 0) to (2, StartRoot 6 EndRoot) is not 3 units.
No, the distance from (0, 0) to (2, StartRoot 6 EndRoot) is not 3 units.
Answers
Answer:
The correct option is;
No, the distance from (0, 0) to (2, √6) is not 3 units
Step-by-step explanation:
The given parameters of the question are as follows;
Circle center (h, k) = (0, 0)
Point on the circle (x, y) = (3, 0)
We are required to verify whether point (2, √6) lie on the circle
We note that the radius of the circle is given by the equation of the circle as follows;
[tex]Distance \, formula = \sqrt{\left (x_{2}-x_{1} \right )^{2} + \left (y_{2}-y_{1} \right )^{2}}[/tex]
Distance² = (x - h)² + (y - k)² = r² which gives;
(3 - 0)² + (0 - 0)² = 3²
Hence r² = 3² and r = 3 units
We check the distance of the point (2, √6) from the center of the circle (0, 0) as follows;
[tex]\sqrt{\left (x_{2}-x_{1} \right )^{2} + \left (y_{2}-y_{1} \right )^{2}} = Distance[/tex]
Therefore;
(2 - 0)² + (√6 - 0)² = 2² + √6² = 4 + 6 = 10 = √10²
[tex]\sqrt{\left (2-0 \right )^{2} + \left (\sqrt{6} -0 \right )^{2}} = 10[/tex]
Which gives the distance of the point (2, √6) from the center of the circle (0, 0) = √10
Hence the distance from the circle center (0, 0) to (2, √6) is not √10 which s more than 3 units hence the point (2, √6), does not lie on the circle.
