Given: △RMN and △QPN where RN=NQ and ∠R=∠Q
To prove: △RMN ≅△QPN
Proof:- In △RMN and △QPN
∠R=∠Q............[given]
RN=NQ............[given]
∠RNM=∠PNQ............[vertically opposite angles]
∴△RMN ≅△QPN [by ASA Congruence Postulate ]
Therefore,C. is the right answer. ASA Congruence Postulate proves that △RMN and △QPN are congruent.
ASA Congruence Postulate states that is two angles and the included side is equal to the two angles and the included side of the other triangle, then the triangles are said to be congruent.
Write an equation of the line containing the point (3,1) and perpendicular to the line 4x−3y=5.
Final answer:
To find the equation of the line perpendicular to 4x-3y=5 that passes through (3,1), we determine the negative reciprocal of the original line's slope, which is -3/4, and use the point-slope form to establish the new line's equation:
y = (-3/4)x + 13/4.
Explanation:
To write an equation of the line containing the point (3,1) and perpendicular to the line 4x−3y=5, first, we need to find the slope of the given line by rearranging the equation into slope-intercept form (y=mx+b), where m is the slope.
The line 4x - 3y = 5 can be rewritten as 3y = 4x - 5, or y = (4/3)x - 5/3. This gives us a slope of 4/3. The slope of a line perpendicular to this will be the negative reciprocal, hence the perpendicular slope is -3/4.
Next, given the point (3,1), we can use the point-slope form of a line's equation, which is y - y₁ = m(x - x₁), where (x₁,y₁) is the point the line passes through, and m is the slope. Substituting the values, we get y - 1 = (-3/4)(x - 3).
Finally, to express the equation in slope-intercept form (y=mx+b), we expand and simplify: y - 1 = (-3/4)x + 9/4, which gives us y = (-3/4)x + 13/4 as the equation of the line.
If the discriminant is 16 in a quadratic equation what is true about its solutions
If the discriminant in a quadratic equation is 16, a positive number, then the quadratic equation will have two distinct real solutions.
Explanation:In mathematics, particularly in quadratic equations, the discriminant plays a vital role in determining the nature of the solutions. The discriminant in a quadratic equation is the part under the square root in the quadratic formula, and it is usually represented by the symbol Δ (Delta). The quadratic formula is given by x = [-b ± sqrt(Δ)] / 2a. Now, if the discriminant is 16 (a positive number), then the quadratic equation will have two distinct real solutions. This is because the square root of a positive number yields two real numbers (one positive and one negative) which provide the two solutions when substituted back into the quadratic formula.

what strategies can be used to divide whole numbers?
Tickets for the baseball games were $2.50 for general admission and 50 cents for kids. If there were six times as many general admissions sold as there were kids tickets, and the total receipts were $7750, how many of each type of ticket were sold?
The number of tickets sold of each type is required.
Number of general tickets sold is 3000 and kids tickets is 500.
The cost of general tickets is $2.5
Cost of kids tickets is $0.5
Number of general tickets sold = x
Number of kids tickets sold = y
Total value of tickets sold = $7750
Now,
[tex]x=6y[/tex]
[tex]2.5x+0.5y=7750\\\Rightarrow 2.5(6y)+0.5y=7750\\\Rightarrow 15.5y=7750\\\Rightarrow y=\dfrac{7750}{15.5}\\\Rightarrow y=500[/tex]
[tex]x=6\times 500=3000[/tex]
Number of general tickets sold is 3000 and kids tickets is 500.

Evaluate S5 for 300 + 150 + 75 + … and select the correct answer below.
Answer:
581.25
Step-by-step explanation:
Use the formula for when the last term is unknown. It is [tex]s_{n} = \frac{a_{1} - a_{1} (r)^{n} }{1-r}[/tex].
For this equation [tex]s_{n}[/tex] (sum of the numbers)= [tex]s_{5}[/tex], [tex]a_{1}[/tex] (amount of first term) = 300, r (ratio)= .5, and n (number of terms) = 5. Knowing this, we plug them into the equation. It would look like: [tex]s_{10} = \frac{300 - (300)(0.5)^{5} }{1-0.5}[/tex].
First, we solve the exponents. 0.5 to the fifth power = .03125. Now multiply it by the nearest number in parentheses, which is 300. You should get 9.375.
Now, subtract that from 300. 300 - 9.375 = 290.625. Your numerator is 290.625.
Simplify your denominator. 1 - 0.5 = 0.5.
Divide.
[tex]\frac{290.625}{0.5} = 581.25[/tex]

Louis spent 12 hours last week practicing guitar. If 1/4 of the time was spent practicing chords, how much time did Louis spend practicing chords?
Final answer:
Louis spent a total of 3 hours practicing chords last week, which is 1/4 of the total 12 hours he dedicated to practicing guitar.
Explanation:
Louis spent 12 hours last week practicing guitar. To calculate the amount of time he spent practicing chords, we need to find 1/4 of 12 hours since 1/4 of the time was dedicated to chords.
Here is the calculation:
Divide the total time by 4 to find 1/4 of 12 hours: 12 hours ÷ 4 = 3 hours.
So, Louis spent 3 hours practicing chords last week.

Based only on the information given in the diagram, which congruence theorems or postulates could be given as reasons why ABC LMN?
Answer:
D, E, and F
Step-by-step explanation:
D. SAS can be used, side-angle-side. The angle is the right angle in both and right angles always are congruent since they can only measure 90 degrees. The heights of both triangles are marked with the same number of slashes, so they are congruent; likewise, the bases are marked with the same number of slashes, so they are congruent. Since the angle is between the sides, or included, this is SAS.
E. HL can also be used since the hypotenuses of both triangles are marked with the same number of slashes, they are congruent. We already decided the legs of both were congruent to each other.
F. LL (which is also exactly the same as SAS) can also be used since we already decided that the legs in both triangles are congruent.
More information about the diagram and angles and sides is needed to determine the congruence theorems or postulates that can be applied.
Explanation:In order to determine which congruence theorems or postulates can be used to prove that triangles ABC and LMN are congruent, we need more information about the diagram and the given angles and sides. Without that information, it is not possible to determine which congruence theorems or postulates can be applied.

Describe the steps in solving the linear equation 3(3x-8)=4x+6
The value of x is 6.
Given,
3(3x-8)=4x+6
We need to solve for x and show steps by steps.
What are the properties used in solving a linear equation?Distributive property of multiplication over addition.
: a ( b + c ) = a x b + a x c
Distributive property of multiplication over subtraction.
: a ( b - c ) = a x b - a x c
Combining like terms.
: cx + ax + b = x (c + a) + b
: cx - ax - b = x (c - a) + b
We have,
3(3x-8)=4x+6
Removing the brackets.
3x(3x) - 3x8 = 4x + 6
9x - 24 = 4x + 6
Subtracting 4x on both sides.
9x - 24 - 4x = 4x + 6 - 4x
5x - 24 = 6
Adding 24 on both sides.
5x - 24 + 24 = 6 + 24
5x = 30
Dividing 5 into both sides.
5x/5 = 30/5
x = 6
Thus the value of x is 6.
