Step-by-step explanation:

Answer:

Option (A)

Step-by-step explanation:

Correct proof to prove the vertical angles are congruent :

1). Linear pairs of angles are supplementary.

   m∠2 + m∠3 = m∠3 + m∠4

2). By subtracting m∠3 from both the sides of the above equation.

3). By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are vertical angles.

Therefore, Option (A) is incorrect in which Angelina showed that linear pairs of angles are complementary.

4x + 6 + 5x + 3 = 90

9x +9 = 90

( Subtract 9 from 9 and 90 )

9x = 81

( Divide 9x and 81 by 9 )

x = 9

Answer: 6042.23

Step-by-step explanation:

P0=d(1−(1+rk)−Nk)(rk).

We have P0=$1,200,000,r=0.0195,k=12,N=20, so substituting in the numbers into the formula gives

$1,200,000=d(1−(1+0.019512)−20⋅12)(0.019512),

that is,

$1,200,000=198.602327d⟹d=

The total interest payable is $4,68,000.

Given,

An executive wishes to take out a $1,200,000 mortgage.

The yearly interest rate on the loan is 1.95% and the loan is for 20 years.

Payments will be made monthly.

Calculate the total interest payable.

Round your answer to the nearest thousand dollars.

It is given by:

SI = (P x R x T) / 100

P = principal amount

R = rate

T = time

We have,

P = $1,200,000

R = 1.95%

T = 20 years

SI = (P x R x T) / 100

SI = (1200000 x 1.95 x 20) / 100

SI = (1,200,000 x 195 x 20) / 100 x 100

SI = 120 x 195 x 20

SI = $4,68,000

Thus the total interest payable is $4,68,000.

Answer:

3.75 or 3 3/4

Step-by-step explanation

Ok the denominators aren't the same so were going to make them the same by them changing into the same number.

we can do thins by timesing 5 by 4=20 and 4 timesing by 5=20

So now that the denominators are the same we have to times 1 by 4 since it denominator was times by same thing with 3 except that only get times by 5.

1 x 4=4 and 3 x 5=15 so now our two fractions are 15/20 and 4/20

15 divided by 4=3.75 and there's our answer.

we get the .75 because it is 3 more so 3 4 x3 =12 that's where we get 3 and then there is 3 left and 3/4 of and 3/4=0.75 and then you combined them to make 3.75.

Answer:

Before solving these, we must know;

· A 90° angle forms a right angle.

· A 180° angle forms a straight angle.

· Any angle greater than a 90° angle is considered an obtuse angle (x > 90 = obtuse).

· Any angle less than a 90° angle is considered an acute angle (x < 90 = acute).

Now just eyeing these, I can tell that;

1. Is acute, because it looks like it is smaller than a 90° angle(right angle).

2. Is straight, because it looks fairly like a straight line(which measures 180°).

3. Is obtuse, because it looks greater than a 90° angle(right angle).

4. Is right, because it looks exactly like a 90° angle(right angle).

Step-by-step explanation:

Since [tex]cos(\frac{\pi}{2})=0[/tex], the denominator will be 0, and the result would be indeterminate.

However, notice that [tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}=2[/tex] by L'Hopital's Rule:

[tex]\lim_{x \to \frac{\pi}{2}} \frac{sin(2x)}{cos(x)}\\\\\frac{2cos(2x)}{-sin(x)}\\ \\\frac{2cos(2(\frac{\pi}{2}))}{-sin(\frac{\pi}{2} )}\\\\\frac{2cos(\pi)}{-1}\\ \\\frac{-2}{-1}\\ \\2[/tex]

Answer:

Well supplementary means that both the angles add up to 180

We know that the measure of angle 3 is 13 degrees.
The measure of angle 4 is unknown
And the total of angles 3 and 4 are 180.
So you can make an equation

13 + x = 180
Solve for x

x= 167

Measure of angle 4 is 167

m< 4 = 167 degrees

Answer:

8r + 9p

Step-by-step explanation:

Combine like terms. Like terms are terms with the same variables as well as the same amount of said variable.

In this case, combine 12p with -3p

8r + 12p - 3p

8r + (12p - 3p)

8r + 9p

8r + 9p is your answer.

~

While adding such algebraic expressions, we combine the like terms which contains the same variables infact same degree of variables.

Given expression:

Here 12p and 3p are like terms because they are having same variable that is p. So, we can compute any operation like hear it's subtraction.

➝ 8r + (12p - 3p)

➝ 8r + 9p

Now no more like terms are there, So the final answer is 8r + 9p. And we are done!

The function shown on the graph has the same rate of change, but a higher starting point

Fine the diagram needed attached.

The rate of change of the line is the slope of the line. The standard equation of a line is expressed as y = mx + b;

Given the equation y = 5x + 5, the rate of change of the expression is 5.

For the given graph, the slope of the graph is expressed as:

(2, 4) and  (0, -6)

m = -6-4/0-2

m =-10/-2

m = 5

Hence the rate of change of the graph is 5.

Answer:

Part A: its linear

Part B: it is a function

Step-by-step explanation:

Resolviendo el sistema de ecuaciones veremos que:

Aqui tenemos el sistema de ecuaciones:

Niña + niño = 51kg

Niño + perro = 46 kg

Niña + perro = 41kg

Para resolver esto, lo primero que debemos hacer es aislar una variable en una de las ecuaciones, por ejemplo, podriamos aislar "perro" en la tercera:

perro = 41kg - niña

Ahora reemplazamos eso en la segunda para obtener:

niño + (41kg - niña) = 46kg

niño - niña = 46kg - 41kg = 5kg

niño = niña + 5kg

Ahora logramos obtener la variable "niño" en terminos de la variable "niña". Podemos reemplazar esto en la primera ecuacion del sistema.

niña + niño = 51kg

niña + (niña + 5kg) = 51kg

2*niña = 51kg - 5kg = 46kg

niña = 46kg/2 = 23kg.

Ahora que sabemos esto, usamos las otras ecuaciones para encontrar el peso del niño y el perro:

niño = niña + 5kg = 23kg + 5kg = 28kg

perro = 41kg - niña = 41kg - 23kg = 18kg.
