Aaron took out a 30-year mortgage for $70,000. His monthly mortgage payment is $466. How much will he pay over 30 years? Interest rate = 7%

Answers

Answer:

[tex]\text{ \$167,760}[/tex]

Explanation:

Here, we want to get how much will be ppaid over the course of 30 years

From the question, we have it that he pays $466 monthly

Now, to get the amount he will pay over the course of the years, we have to understand that there are 12 months in a year

The total number of months for which he will be paying will be:

[tex]30\times\text{ 12 = 360}[/tex]

He will be paying $466 per month for a total of 360 months

So, the total amount he is to pay is the product of this two

Mathematically, that would be:

[tex]360\times466\text{ = 167,760}[/tex]

INT ALGEBRAL: 1. Write an equation that passes through (0,5) and is parallel to 3x+5y=6

Thank you for your help, and please do show work! I will be looking to give the Brainliest answer to someone!

Answers

The equation of the parallel line is y = -3/5x + 5

How to determine the line equation?

The equation is given as

3x + 5y = 6

The point is also given as

Point = (0, 5)

The equation of a line can be represented as

y = mx + c

Where

Slope = m and c represents the y-intercept

So, we have

3x + 5y = 6

This gives

5y = -3x + 6

Divide

y = -3/5x + 6/5

By comparing the equations y = mx + c and y = -3/5x + 6/5, we have the following

m = -3/5

This means that the slope of y = -3/5x + 6/5 is -3/5

So, we have

m = -3/5

The slopes of parallel lines are equal

This means that the slope of the other line is -3/5

The equation of the parallel line is then calculated as

y = m(x - x₁) +y₁

Where

m = -3/5

(x₁, y₁) = (0, 5)

So, we have

y = -3/5(x + 0) + 5

Open the brackets and evaluate

y = -3/5x + 5

Hence, the parallel line has an equation of y = -3/5x + 5

ExplanationPart a)

We know that two triangles are similar if two pairs of corresponding angles are equal.

In this case, we have:

• Angles EDC and ABC are right angles. Then, these angles are equal.

,

• Angles DCE and ACB are ,vertical angles,. In other words, they are opposite angles made by two intersecting lines. Vertical angles are ,congruent,, then these angles are equal.

Answer

Since the above condition is fulfilled, triangles ABC and EDC are similar.

Part b)

When two triangles are similar, their corresponding sides are in the same ratio.

f A and B are independent events with P(A)=0.3 and P(B)=0.7, find P(A AND B). Provide your answer below:

Answers

If A and B are independent events with P(A) = 0.3 and P(B) = 0.7, then the value of P(A AND B) = 0.21

A and B are independent events

Independent events are events that does not depends on any other events.

Probability is the ratio of number of favorable outcomes to the total number of outcomes

The value of P(A) = 0.3

The value of P(B) = 0.7

If A and B are independent events, then P(A AND B) = P(A) × P(B)

Substitute the values in the equation

P(A AND B) = 0.3 × 0.7

= 0.21

Hence, if A and B are independent events with P(A) = 0.3 and P(B) = 0.7, then the value of P(A AND B) = 0.21

A grocery store sales for $522,000 and a 25% down payment is made a 20 year mortgage at 7% is obtain compute and amortization schedule for the first three months round your answer to two Decimal place if necessary

Answers

The value of the mortgage (the real amount to be financed) is A = $391,500.

The annual interest rate is r = 7%. We must convert it to montly decimal rate:

r = 7 / 12 / 100 = 0.005833

Note: The decimals will be kept in our calculator. Only two decimal places will be shown in the results.

The monthly payment is R = $3,034.13 which includes interest and principal.

For the first month, the loan has not been paid upon, so the interest for this period is:

I = $391,500 * 0.005833 = $2,283.75

From the monthly payment, the portion that goes to pay the principal is:

$3,034.13 - $2,283.75 = $750.38

So the new balance of the loan is:

$391,500 - $750.38 = $390,749.62

Thus, for payment 1:

Interest - Payment on Principal - Balance of Loan

$2,283.75 - $750.38 - $390,749.62

Repeating the calcuations for the second payment:

The interest for this period is:

I = $390,749.62 * 0.005833 = $2,279.37

From the monthly payment, the portion that goes to pay the principal is:

$3,034.13 - $2,279.37 = $754.76

So the new balance of the loan is:

$390,749.62 - $754.76 = 389,994.86

The table is updated as follows:

Interest - Payment on Principal - Balance of Loan

$2,283.75 - $750.38 - $390,749.62

$2,279.37 - $754.76 - $389,994.86

For the third month:

The interest for this period is:

I = $389,994.86 * 0.005833 = $2,274.97

From the monthly payment, the portion that goes to pay the principal is:

$3,034.13 - $2,274.97 = $759.16

So the new balance of the loan is:

$389,994.86 - $759.16 = $389,235.70

The final updated table is:

Interest - Payment on Principal - Balance of Loan

$2,283.75 - $750.38 - $390,749.62

$2,279.37 - $754.76 - $389,994.86

$2,274.97 - $759.16 - $389,235.70

She started her drawing with theballoons, which she wanted to make all the same size.She drew a circle for the balloon and found the radius, which was 9cm. How big around will all ofAudrey's balloon drawings be?——Please help me.

Answers

Audrey drew a circle for the balloon, this circle has a radius of 9 cm.

To know how big the baloon is you have to determine its circumference.

To calculate the circumference of a circle you have to multiply its diameter by number pi:

[tex]C=d\pi[/tex]

The formula is C=dπ

The diameter is twice the circle so the diameter of the baloon is:

[tex]\begin{gathered} d=2r \\ d=2\cdot9 \\ d=18\operatorname{cm} \end{gathered}[/tex]

The calculation for the diameter is:

d=2r

d=2*9

d=18cm

So the circumference of a circle with diameter 18cm is:

[tex]\begin{gathered} C=18\pi \\ C\cong56.548\operatorname{cm} \end{gathered}[/tex]

For this balloon:

C=18π

How to interpret the graph?

From the coordinates of this graph, we can reasonably infer and logically deduce that it models a straight line, shows a proportional relationship and can be represented by using a linear function.

Mathematically, a proportional relationship can be represented by the following equation:

g = kc

Where:

k is the constant of proportionality.g represent the pounds of grapes.c represent the cost of grapes in dollar.

Next, we would determine the constant of proportionality (k) for the data points shown on this graph as follows:

k = g/c

k = 1/2 or 0.5

Therefore, the linear equation is given by g = 0.5c.

For the amount of dollar needed at g = 1, we have:

g = 0.5c

c = g/0.5

c = 1/0.5

c = $2.

(A) A shipment of 10 cameras will likely have 6 defectives. If a person buys 2 cameras, what is the probability of getting 2 defectives?(B) What are the odds in favor of getting a defective camera?

Answers

To solve the exercise, you can use the formula of the binomial distribution:

[tex]\begin{gathered} P(x)=\binom{n}{x}p^x(1-p)^{n-x} \\ \text{ Where } \\ n\text{ is the number of trials (or the number being sampled)} \\ x\text{ is the number of successes desired} \\ p\text{ is the number of getting a success in one trial} \end{gathered}[/tex]

So, in this case, we have:

[tex]\begin{gathered} n=10 \\ p=\frac{6}{10}=0.6 \end{gathered}[/tex]

Because "success" is that there are defective cameras, 6 defective cameras out of 10 in total.

For part A, we have:

[tex]\begin{gathered} x=2 \\ P(x)=\binom{n}{x}p^x(1-p)^{n-x} \\ P(2)=\binom{10}{2}\cdot0.6^2\cdot(1-0.6)^{10-2} \\ P(2)=\binom{10}{2}\cdot0.6^2\cdot(0.4)^8 \\ P(2)=45\cdot0.36\cdot0.00065536 \\ P(2)=0.0106 \end{gathered}[/tex]

Therefore, the probability of getting 2 defective cameras is 0.0106.

For part B, we have:

[tex]\begin{gathered} x=1 \\ P(x)=\binom{n}{x}p^x(1-p)^{n-x} \\ P(1)=\binom{10}{1}\cdot0.6^1\cdot(1-0.6)^{10-1} \\ P(1)=\binom{10}{1}\cdot0.6^1\cdot(0.4)^9 \\ P(1)=10\cdot0.6\cdot0.000262144 \\ P(1)=0.0016 \end{gathered}[/tex]

What is the value of an edge length of the larger prism in centimeterMecand vou answer and now in the bubbles on your answer document. Be sure to use thecorect place value

Answers

Ok, we have here two similar prisms, which means that the length of every sides of one prism is proportional to the correspondent side of the other prism.

From this, we have the following relation: (7/2.8) = (x/11.2)

Multiplying both sides by 11.2, we got: x = (11.2*7)/2.8 = 28 cm.

SOLUTION

We want to solve the question below

We can see that a matrix was subtracted from another. In Addition or subtraction of matrix, we just add or subtract the element. So

We have in the first row

[tex]\begin{gathered} -20-(-5)=x \\ -20+5=x_ \\ x=-15 \end{gathered}[/tex]

And

[tex]\begin{gathered} 16-1=y \\ 15=y \\ y=15 \end{gathered}[/tex]

Hence x = -15 and y = 15, the first option is correct
