[tex] \bigstar \: \underline{ \underline{ \tt{Question}}} : [/tex] In The Given Figure , M And N Are

Answers

Answer 1

Answer:

See Below.

Step-by-step explanation:

We are given two intersecting circles with centers M and N.

And we want to prove that: I) PQ ⊥ MN and that II) PR = RQ.

Since MP and MQ are radii of the same circle:

[tex]MP\cong MQ[/tex]

Likewise, since NP and NQ are radii of the same circle:

[tex]NP\cong NQ[/tex]

And by the Reflexive Property:

[tex]PQ\cong PQ[/tex]

Therefore, by SSS Congruence:

[tex]\Delta MPN\cong \Delta MQN[/tex]

By CPCTC:

[tex]\displaystyle \angle PMN\cong \angle QMN[/tex]

And by the Reflexive Property:

[tex]MR\cong MR[/tex]

And since they are the radii of the same circle:

[tex]MP\cong MQ[/tex]

Therefore, by SAS Congruence:

[tex]\Delta MPR\cong \Delta MQR[/tex]

Therefore, by CPCTC:

[tex]PR\cong RQ[/tex]

Note that PQ is a chord in Circle M.

Therefore:

[tex]\text{Segment $MN$ bisects chord $PQ$}[/tex]

In a circle, a segment that passes through the center of the circle that is perpendicular to a chord also bisects the chord.

And conversely, a segment that passes through the center of a circle that bisects a chord in the circle is also perpendicular to the chord.

So:

[tex]\displaystyle PQ\perp MN[/tex]

Answer 2

Answer:

Step-by-step explanation:

First step is to prove triangle MPN ad MQN are congruent.

MP=MQ, radius of circle M

NP=NQ, radius of circle N

we have two S in SAS  and for A, we need to prove angle MPN = MQN

consider triangle QMP, it is isosceles so angle MPQ = MQP

consider triangle QNP; it is isosceles so angle  QPN = PQN

combining the two above

angle MPN = MPQ+QPN = MQP+PQN = MQN

By SAS, triangle MPN and MQN are congruent

By symmetry, MN is perpendicular to PQ

It also disects PQ so PR = RQ

Solve the system of equations x+2y=-16 and x+6y=-28 by combining the equations.

Answers

Answer:

x= -18 y=-5/3

Step-by-step explanation:

Answer:

x = -10

y = -3

Step-by-step explanation:

When combining the equations, we must ensure that one of the two variables will cancel out. The easiest way to do this will be to multiply one of the equations by -1, such that the x will cancel out once they are added together. This can be done with either equation, but I will do it for the first one.

This gives us the system:

[tex]\left \{ {{-x-2y=16} \atop {x+6y=-28}} \right.[/tex]

We can then add the two equations by combining each of the terms:

[tex](x - x) + (6y - 2y) = (-28 + 16)\\(0) + (4y) = (-12)\\4y = -12\\y = -3[/tex]

Now that we have the value for y, we substitute it back into any of the original equations and solve for x:

[tex]x + 2y = -16\\x + 2(-3) = -16\\x - 6 = -16\\x = -10[/tex]

To check our work, we substitute both x and y into the other original equation:

[tex]x + 6y = -28\\(-10) + 6(-3) = -28\\-10 - 18 = -28\\-28 = -28[/tex]

The average number of slam dunks between the sophomore basketball league members is 20. The average number of slam dunks between the sophomore and junior basketball league members is 30. If there are 40 members in the sophomore league and 20 members in the junior league, how many slam dunks are made in the junior league?

Answers

Answer:

The sum of the slam dunks made in the junior league is 1,000 slam dunks

Step-by-step explanation:

The known parameters are;

The average number of slam dunks between the sophomore basketball league members, μ₁ = 20

The average number of slam dunks between the sophomore and junior basketball league members, μ₃ = 30

The number of members of the sophomore league, n₁ = 40

The number of members of the junior league, n₂ = 20

We get;

The sum of the scores of the sophomore league members, S₁ = μ₁ × n₁

∴ S = 20 × 40 = 800

The sum of the scores of the sophomore and junior league members combined, S₃ = (n₁ + n₂) × μ₃

∴ S₃ = (40 + 20) × 30 = 1,800

The sum of the slam dunks made by the junior league members, S₂ = S₃ - S₂

∴ S₂ = 1,800 - 800 = 1,000

∴ The sum of the slam dunks made in the junior league, S₃ = 1,000

There are 22,521 more people living in the suburbs of a city than in the city. If 17,245 people live in the​ city, how many people live in the​ suburbs?

Answers

Answer:

Number of people in the suburbs= 39,766

Step-by-step explanation:

Giving the following information:

22,521 more people are living in the suburbs of a city than in the city.

Number of people in the city= 17,245

To calculate the number of people that lives in the suburbs, we need to use the following formula:

Number of people in the suburbs= Number of people in the city + 22,521

Number of people in the suburbs= 17,245 + 22,521

Number of people in the suburbs= 39,766

Answers

Answer:

When Kiran is 13, his aunt will be 28.

When Kiran's aunt is 60, he will be 45.

Step-by-step explanation:

Hope this helps!

Answer:

a) 28 (kiran's aunt when kiran is 13)

b) 45 (kiran when kiran's aunt is 60)

Step-by-step explanation:

first

let kiran's age be k

kiran's aunt= 15 + k

when kiran is 13, kiran's aunt is 15+13

15+13= 28

when kiran's aunt is 60;

15+k = kiran's age

60 = 15+ k

k = 60-15

k = 45

If you have 2 cans of tomato soup, 3 cans of chicken soup, 2 cans of cheese soup, 2 cans of potato soup and 1 can of beef soup what is the probability that he will choose a ca of tomato and a can of cheese soup

Answers

Answer:

1/25

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

probability of choosing a can of tomato and a can of cheese soup = probability of choosing a can of tomato x probability of choosing a can of cheese soup

total number of cans = 2 + 3 +2 + 2 + 1 = 10

probability of choosing a can of tomato = number of can of tomato / total number of cans

= 2/10 = 1/5

probability of choosing a can of cheese soup = number of can of cheese soup / total number of cans

= 2/10 = 1/5

1/5 x 1/5 = 1/25

The complete exercise with the answer options is as follows:

Mancini's Pizzeria sells four types of pizza crust. Last week, the owner tracked the number sold of each type, and this is what he found.

Type of Crust Number Sold

Thin crust            364

Thick crust             240

Stuffed crust             176

Pan style            260

Based on this information, of the next 3000 pizzas he sells, how many should he expect to be thick crust? Round your answer to the nearest whole number. Do not round any intermediate calculations.

Answer:

692 thick crust pizzas

Step-by-step explanation:

With the data given in the exercise, we must first find the total number of pizzas, then we must find the proportion between the thick crust pizzas and the total number of pizzas, finally we must propose a rule of three to find the new proportion of crust pizzas thick on a total of 3000 pizzas.

Type of Crust Number Sold

Thin crust            364

Thick crust             240

Stuffed crust             176

Pan style            260

total pizzas  : 1040

Now we must calculate for 3000 pizzas how much would be the total of thick crust pizzas.For that we must use the relationship found, that is, in 1040 pizzas there are 240 thick crust pizzas

1040→240

3000→x

x= [tex]\frac{3000x240}{1040}[/tex] = 692

Now we have a new proportion that out of 3000 pizzas there are a total of 692 thick crust pizzas

Answer:

The height is 8 inches

Step-by-step explanation:

Well to find the volume of a cylinde like this, he formula is Base * height.

To find the base we need to find the area of the circle.

a=πr^2

The radius is 3 inches, 3^2=9

Since π is suppose to be 3.14 multiply

9*3.14= 28.26

We know that the cylinder can hold 231 cubic inches. So technically it can fill (x) 28.26 inches.

solve the equation

28.26x=231

Divide

231/28.26

The answer would be about 8 inches

Select all equations whose graphs have a vertex with x-coordinate 2

A. y=(x-2)(x-4)
B. y=(x-2)(x+2)
C. y=(x-1)(x-3)
D. y=x(x+4)
E. y=x(x-4)

Answers

Answer:

C

Step-by-step explanation:

because you have to foil then do -b/2a

By finding the x-coordinate of each vertex, we will see that the correct options are C and E.

How to identify the x-value of the vertex?

For a quadratic equation of the form:

y = (x - a)*(x - b)

Where a and b are the roots, such that a < b, the x-value of the vertex is given by:

a + (b - a)/2

With that, we can check the x-value of the vertex of each option.

A) y=(x-2)(x-4)

The x-value of the vertex is:

2 + (4 - 2)/2 = 3

B)  y=(x-2)(x+2)

The x-value of the vertex is:

-2+ (2 - (-2))/2 = 0

C)  y=(x-1)(x-3)

The x-value of the vertex is:

1 + (3 - 1)/2 = 2

D) y = x(x+4) = (x - 0)*(x + 4)

The x-value of the vertex is:

-4 + (0 - (-4))/2 = -2

E)  y=x(x-4) = (x - 0)*(x - 4)

The x-value of the vertex is:

4 + (0 - (4))/2 = 2

So the two options that have a vertex with x-coordinate 2 are options C and E.
