Answer:

Triangles are congruent due to SAS

Angles are congruent due to CPCTC

Step-by-step explanation:

In order to prove the congruency of the angles, we have to prove the congruency of the triangles.

ME=MR is given so that is a side

They share angle M so that is an angle

And, MA=MN which is given so that is a side.

The two triangles are congruent due to SAS postulate

So the angles are equal due to CPCTC

Angles E and R are congruent as they are the corresponding parts of two congruent triangle.

Given is a figure which shows two connected triangles ΔEMA and ΔRMN,

We need to prove ∠E ≅ ∠R.

Considering the triangles,

ME = MR [given]

MA = MN [given]

∠M is common angle in both triangles,

So, ΔEMA ≅ ΔRMN by SAS postulate.

So, ∠E ≅ ∠R by CPCTC.

Hence proved.

Q.3 - The table and the graph each show a different relationship between the same two variables, x and y:


How much more would the value of y be in the table than its value on the graph when x = 11?

Answers

Because y=20x in this table, the value of y is worth 20 times as much as the value of 11.

How can I tell which graph represents the function's graph?

A feature's graph In a plane of the form (x, f(x)), all factors have the form f. As a side note, the graph of f may also be thought of as the graph of y = f. (x). Because of this, a feature's graph is a particular case in the graph of an equation.

When it comes to graphing, what exactly is the axis?

To explain the graph's meaning and the measuring devices, an axis is a line drawn to the graph's aspect or backside. It is possible to provide information about what the graph shows by labeling the x-axis, the horizontal line at its lowest point.

Answers

Answer:

1/3^3

Step-by-step explanation:

The answer is 1/3^3 or 1/27 because 3^2 is 9 and 3^-5 is 1/243. This results in the equation 9 x 1/243. When simplified you get 1/3^3 or 1/27.

3^2(3^-5) = 3^2-5 = 3^-3 = 1/3^3

Answer:

[tex]\huge\boxed{\sf x =28 \textdegree}[/tex]

Step-by-step explanation:

Given that,

∠IAK = 62°

∠IAK + ∠IAD = 90° (Complementary angles)

62 + ∠IAD = 90°

Subtract 62 to both sides

∠IAD = 90 - 62

∠IAD = 28°

∠IAD = ∠ACB (Corresponding angles are equal)

So,

∠ACB = 28°

∠ACB = ∠GCJ (Vertically opposite angles are equal)

So,

28° = x°

OR

x° = 28°

[tex]\rule[225]{225}{2}[/tex]

Answer:

28 degrees

Step-by-step explanation:

If two lines cross each other, it makes 4 angles, and 2 angles from opposite sides have the same length. Since line KL and line IJ crossed, angle KAI and angle LAJ will have the same angle.

--> Angle LAJ is 62 degrees

If we look closely, there is a triangle ABC, and since the question said that line KL and line FG is perpendicular, the angle ALG will be 90 degrees.

We know that in a triangle, there are three angles, and the angle measures combined equals 180.

Since we know two angles: 90 and 62, we take them away from 180 to find the last angle BCA.

--> 180 - 90 - 62 = 28

--> Angle BCA = 28 degrees

Like I said at the beginning, if two lines cross each other, opposite angles are the same size. So angle x will also be equal to angle BCA, which is 28 degrees.

Angle x = 28 degrees

Maybe that I'm wrong, Only one way to find out.

We want to combine any like terms and distribute the signs properly to the terms in the parentheses.

First, remove the parentheses by distributing the signs:

[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]

The simplified form is [tex]-x + 9[/tex].

Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

Determine the zeros, and explain what these values mean in the context of the problem.

x = 9, x = 18; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 9, x = 18; The zeros represent the number of monthly memberships when no profit is made.
x = 6, x = 12; The zeros represent the number of monthly memberships that produces a maximum profit.
x = 6, x = 12; The zeros represent the number of monthly memberships when no profit is made.

Answers

Answer: the zeros are at (6,0) and (12,0) where no profit is made.

option D

Step-by-step explanation: you can find the zeros ( the x-intercepts), by either graphing out the function or factoring it.

in this scenario, there is no y increase, which means 0 profit.

A(8,4)
B(10,4)
C(13,-1)
D(8,-1)
What is the length of the side AD?

Answers

Answer: 5

Step-by-step explanation:

If the sides of A is (8,4) and the coordinates of D is (8-1), the same value in both coordinates are 8 and the different values are 4 (A) and -1 (D). We will take the absolute values (AV) of both when added: |4 + -1|.

The answer will be 5 grids (or whatever measurements the question uses).

The answer is 5 units because if you have a graph you can count from (8,4) to (8,-1) and it equals 5

What is the total amount due after 6 months on an initial loan of $1,400 at 12.5% annual interest.

Answers

Answer:  $1487.50

Step-by-step explanation:

hey there again!

Facts:

Principal (starting amount): $1,400

Annual interest rate: 12.5% of the principal. Whenever you get an annual interest rate as a percentage, its always that percentage of the starting amount.

Time given: 6 months, 1/2 a year

the question asks "total amount due' in 6 months. Basically, we want to know how much they will have in their account after 6 months.

Step 1: Find how much interest he will get in 6 months as a percentage.

6 months is 1/2 of a year, so find 1/2 of 12.5

1/2 of 12.5

1/2 x 12.5

0.5 x 12.5

6.25%

Step 2: Find how much interest he gets, but as a number.

Principal: $1400

6.25% of 1400= $87.50

Step 3: Find the total amount of money he will have after 6 months.

he starts with 1400, and gets an additional $87.50 added to his account after 6 months. How much does he have now?

To answer this, add to find the total:

87.50+1400= $1487.50

The answer is 1487.50 :)

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%

Answers

1) figure out interest amount

400x.12= 48

2) add interest and loan amount

400+48= 448

You would have to pay back $448 in total after one year.

What is the amount on the loan?

The simple interest formula can be expressed as;

I = P × r × t

Where I is interest, P is principal, r is interest rate and t is time.

Given the parameters:

Principal P = $400 (the initial loan amount)

Rate r = 12% = 12/100 = 0.12

Time t = 1 year

Interest = ?

To determine the interest, we can use the above formula for simple interest:

I = P × r × t

Interest = $400 × 0.12 × 1

Interest = $48

Money to be paid back will be:

Amount = Principal + Interest

Amount = $400 + $48

Amount = $448

Therefore, the accrued amount to be paid is $448.

Karl has 5 blue pencils, 3 yellow pencils and 2 black pencils. If Karl selects 2 pencils at random from his pencil case, without replacement, what is the probability that both pencils are not yellow?

Answers

In total you have 10 pencils but only 2 of them are yellow. Therefore when simplify this, the changes of not picking a yellow pencil is 8/10 which simplify to 4/5. There’s a 4/5 chance neither pencils will be yellow
The probability is 42/90 simplified to 7/15

Equation: probability of first non-yellow pencil x probability of second non-yellow pencil
7/10*6/9= 42/90= 7/15

There are 7 total pencils that are not yellow but because you don’t put the non-yellow pencil back there is a decrease in both the non-yellows and total pencils!

The answer is C. Why? Well, see below!

A would be incorrect because the problem is asking what the area of the stamp would be. In order to find area, we multiply length and width by each other. The given equation we initially had shows division, and would therefore be incorrect. B would be incorrect because although the equation has the correct evaluation symbol, the formula for identifying length would be L = A / W, which means length equals area divided by width. Because the area is 1/4 in this problem, the expression used for evaluation would be 1/4 divided by 1/5. D is incorrect because, like B, the evaluation expression would be 1/4 divided by 1/5.
