Are the triangles congruent Why or why not triangle congruence ASA and AAS?
Answers
ΔABC and ΔRQM are congruent triangles. They are congruent by either ASA or AAS.
Two triangles are said to be congruent if their all corresponding sides are equal and all corresponding angles are equal in measure.
For the given question,
We know that the sum of all angles of a triangle is 180°.
For ΔABC,
∠A + ∠B + ∠C = 180°
42° + 53° + ∠C = 180°
95° + ∠C = 180
∠C = 85°
For ΔABC and ΔRQM,
∠A = ∠R
∠C = ∠Q
AB = RM
So, by the AAS postulate, ΔABC and ΔRQM are congruent triangles.
For ΔRQM,
∠R + ∠Q + ∠M = 180°
42° + 85° + ∠M = 180°
∠M = 53°
For ΔABC and ΔRQM,
∠A = ∠R
∠B = ∠M
AB = RM
So, by the ASA postulate, ΔABC and ΔRQM are congruent triangles.
Therefore, ΔABC and ΔRQM are congruent triangles. They are congruent by either ASA or AAS.

What is the name of concurrency for medians of a triangle?
Answers
The concurrency point for medians of a triangle is known as centroid.
A median is a line drawn from one of the vertices of a triangle that bisects the side opposite to the vertex. Since there are 3 vertices in a triangle, there are also 3 medians in a triangle. A median divides the triangle into 2 equal halves.
The 3 medians of a triangle intersect at a point inside the triangle. This point is known as the centroid of the triangle. It is the center point of a triangle and divides the medians in the ratio of 2 : 1.
Thus, the name of concurrency for medians of a triangle is centroid.

The product of 5 and the sum of 3 and a number is 20.
Answers
Answer:
The product of 5 and the sum of 3 and 1 is 20
Step-by-step explanation:
Equation:
5*(3+x)=20
15+5x=20
5x=5
x=1
You need to multiply 5 by three and x
5 (3 + x) = 20 5*3 = 15 5*x = 5x
Second step: Add 15 to both sides
15-15 = 0 20-15 = 5
15 + 5x = 20
-15 -15
Step three: Divide 5 from both sides
5x/ 5 = x
5/5 = 1
5x = 5
X= 1

What is the point of concurrence of perpendicular bisectors of a triangle?
Answers
The points of concurrency of perpendicular bisectors of triangle is circumcenter.
A point of concurrency shared by three or more lines is referred to as a single point of concurrency. Constructed lines in triangle interiors are excellent places to look for points of convergence.
When you construct a triangle's medians, perpendicular bisectors, angle bisectors, or altitudes, you create a point of concurrency for each of them.
Because the triangle can have four distinct types of line segments, it can have four distinct points of convergence. Each point of concurrency represents the intersection of a particular type of line segment: centroid, circumcenter, incenter, and orthocenter.
The centroid of the triangle is the point of convergence shared by the three medians.The point at which the triangle's three angle bisectors intersect is known as the incenter.The three perpendicular bisectors will intersect at the circumcenter, which is a point of convergence.The orthocenter is the point at which the three altitudes/heights of a triangle intersect.Thus, the points of concurrency of perpendicular bisectors of triangle is circumcenter.

Answers
A dairy farmer needs to mix 450 pounds of protein supplement, 30 pounds of protein ration and 480 pounds of high-grade protein ration.
Given that, a dairy farmer wants to mix a 45% protein supplement.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let x be number of pounds farmer wants to mix a 45% protein supplement.
Here,
0.45x + 0.15(1200-x) = 0.40(1200)
⇒ 0.45x +180-0.15x = 480
⇒ 0.30x=480-180
⇒ 0.30x=300
⇒ x=300/0.30
⇒ x=1000
Here, 45% of 1000
= 450 pounds
15% of (1200-100)
= 0.15×200
= 30 pounds

Using the compound interest formula, if the account compounds at 4.8% monthly and he withdraws $500 monthly, it will take Steve 33 years, 7 months (403 months) to reduce $100,000 to a balance (future value) of $0.
What is the difference between the future and present value?The future value is the compounded present value, while the present value is the discounted future value.
However, with periodic withdrawals, a present value that compounds at an interest rate into the future can become $0 (future value) after some periods.
The time (period) Steve reduces his inheritance to $0 can be computed using an online finance calculator as follows:
I/Y (Interest per year) = 4.8%
PV (Present Value) = $100,000
PMT (Periodic Payment) = $-500
FV (Future Value) = $0
Results:
N (# of periods) = 403.164
Sum of all periodic payments = $-201,581.83

An isosceles triangle therefore has both two equal sides and two equal angles.
What is traiangle?
A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
What is isosceles triangle?
An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
Any triangle with (at least) two equal sides is said to be isosceles. The remaining side in the previous illustration has length in addition to the two equal sides. This characteristic equates to the triangle's two angles being equal. Therefore, an isosceles triangle has two equal sides as well as two equal angles. The Greek words iso (same) and skelos are the source of the name (leg).
An equilateral triangle is one in which all of its sides are equal, whereas a scalene triangle is one in which none of its sides are equal. Therefore, an equilateral triangle is a specific example of an isosceles triangle that has equal sides and angles on all three of its faces. The isosceles right triangle is yet another unique instance of an isosceles triangle.
The Pythagorean theorem can be used to determine the height of the isosceles triangle shown in figure:
[tex]h = \sqrt{b^2-\frac{1}{4}a^2 }[/tex]
Consequently, the region is given by:
A=1/2ah
A = [tex]\frac{1}{2}a\sqrt{b^2-\frac{1}{4}a^2 }[/tex]

A firm has the marginal-demand function where D(x)=-1400x÷√25-x² is the number of units sold at x dollars per unit. Find the demand function given that D=17,000 when x=3 per unit.
The demand function is D(x)=
Answers
The equation of the demand function is D(x) = 1400√(25-x²) + 11400
How to determine the demand function?From the question, we have the following parameters that can be used in our computation:
Marginal demand function, D'(x) = -1400x÷√25-x²
Also, we have
D = 17000, when the value of x = 3
To start with, we need to integrate the marginal demand function, D'(x)
So, we have the following representation
D(x) = 1400√(25-x²) + C
Recall that
D = 17000 at x = 3
So, we have
17000 = 1400√(25-3²) + C
Evaluate
17000 = 5600 + C
Solve for C
C = 17000 - 5600
So, we have
C = 11400
Substitute C = 11400 in D(x) = 1400√(25-x²) + C
D(x) = 1400√(25-x²) + 11400
Hence, the function is D(x) = 1400√(25-x²) + 11400

Answers
Y = 1x – 2 is the equation for linear regression.
Explain about the linear regression equation?
A linear regression line is represented by the equation Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of a line, b, is equal to the intercept of that line, which is the value of y when x = 0.
Based on the value of another variable, linear regression analysis can be used to predict the value of a variable. You want to be able to predict the dependent variable. You create a forecast about the value of the other variable using the independent variable.
A positive linear relationship exists if the slope of the line is positive, meaning that when one rises, the other rises as well.
Y = -2 -1 x
Y= -2 -1x
Y = 1x - 2
