Answer 1

Answer: The buyer will save 18k dollars

Step-by-step explanation:

He is saving 18k becuase that is 8 percent of 21k

Answer 2

Answer:

The 20 year 8% year loan is more economicalThe buyer will save $159650

Step-by-step explanation:

Use the given formula to calculate each option and compare.

Option 1

P = $210000r = 8.5% = 0.085t = 30n = 1

Find the PMT:

[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.085)/(1-(1+0.085)^{-30})=19541[/tex]

Find the total interest amount:

30*$19581 - $210000 = $377430

Option 2

P = $210000r = 8% = 0.08t = 20n = 1

Find the PMT:

[tex]P(r/n)/(1-(1+r/n)^{-nt})=210000*(0.08)/(1-(1+0.08)^{-20})=21389[/tex]

Find the total interest amount:

20*$21389 - $210000 = $217780

We see option 2 reveals less interest amount, so is more economical.

Saving on interest:

$377430 - $217780 = $159650

2) (–8, –4)

3) (–7, 8)

4) (8, –7)

Answers

Answer:

r = 8 and

s = -7

Step-by-step explanation:

(2r + 4s = - 12)/2 =

r +2s = -6

r = -2s - 6

Substitution:

6 (-2s -6) + 7s = -1

-12s - 36 + 7s = -1

-5s = 36-1

s = 35/-5

s = -7

6r + 7(-7) = -1

6r - 49 = -1

6r = 49-1

r = 48/6

r = 8

Answers

Answer:

1113.75

Step-by-step explanation:

The formula for simple interest is as follows: Simple interest = principal balance x interest rate x term of the loan

P=4500

i= 0.055

t=4.5

multiplying them together we get

1113.75

The reason that this is simple interest is because compound interest increases over time as an exponential

Kristen babysits 38 hours a week for $6.80 per hour. She earns an additional $224.00 in tips . How much did she make in 1 week?

Answers

Answer:

$502.40

Step-by-step explanation:

Kristen works 38 hours for $6.80 per hour.

We multiply her pay and the hours she worked:

                   38 × 6.8 = 258.4

Thus, she makes $258.40/week

                   Now we add her tips, which would be the equation 258.4 + 224

     258.4 + 224 = 502.4

So, she made $502.40 in 1 week

Rocco loves making spaghetti with his grandmother. They make homemade tomato sauce by adding pureed tomatoes, sugar, salt, olive oil, and water. He notices that after he stops stirring, he sees a greasy film at the top of the red liquid. What does this tell you about his sauce mixture?

Oil floats on water because it is less dense I believe. So that would be the oil on top of the sauce(the oil is on top because of the water that was also added).

Answer:

30; -5 is 5 units away from 0 and V is 25 units away from 0, and 5 + 25 = 30.

Step-by-step explanation:

To find the distance between point T, which has a value of -5, and V, which has a value of 25, we should find the absolute value of each number and then add those numbers together.

So, the absolute value of -5 is 5 and the absolute value of 25 is 25. 25 + 5 = 30, and this is the length of TV.

a) 128
b) 126
c) 130
c) 124

Answers

Answer:

I believe there is an error with the problem

Step-by-step explanation:

3*6*2 + 2*6*3 + 6*2 = 36+36+12 = 84

The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126 so option (b) will be correct.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

An expression is a mathematical proof of the equality of two mathematical expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

Given the expression

ab² + 2ab + a²

Now,

a = 6 and b= 3

So,

⇒  6(3)² + 2(6)(3) + 6²

⇒  36 + 54 + 36

126

Hence "The answer of the expression ab² + 2ab + a² for a = 6 and b = 3 will be 126".
