Answer: The value of the car in 2021 will be $11,276.31.

Step-by-step explanation:

If r is the depreciation rate and P is the initiial amount , then the amount after t years is given by:-

$A=P(1-\dfrac{r}{100})^t$

Given: P=21000, r=8.5% , t= 2021-2014= 7

Plug all the values in the formula, we get

$A= 21000(1-\dfrac{8.5}{100})^7\\\\\Rightarrow\ A=21000(1-0.085)^7\\\\\Rightarrow\ A= 21000(0.915)^7\\\\\Rightarrow\ A= 21000(0.5369670)\approx11276.31$

The value of the car in 2021 will be $11,276.31.

Leila is considering buying her first home. The house she is interested in buying is priced at $125,000. Leila can put down a $2

PIT_PIT [208]

Answer:

* The monthly mortgage payment is $629.53 ⇒ answer C

Step-by-step explanation:

* Lets explain how to solve the problem

- Leila is considering buying her first home

- The house she is interested in buying is priced at $125,000

∴ She can put $20000 down payment

* Lets find the balance to be paid off on mortgage

∴ The balance = 125000 - 20000 = 105000

- She qualifies for a 30-year mortgage at 6%

* Lets find the rule of the monthly payment

∵ $pmt=\frac{\frac{r}{n}[P(1+\frac{r}{n})^{tn}]}{(1+\frac{r}{n})^{tn}-1}$ , where

- pmt is the monthly mortgage payment

- P = the initial amount

- r = the annual interest rate (decimal)

- n = the number of times that interest is compounded per unit t

- t = the time the money is invested or borrowed for

∵ P = 105000

∵ r = 6/100 = 0.06

∵ n = 12

∵ t = 30

∴ $pmt=\frac{\frac{0.06}{12}[105000(1+\frac{0.06}{12})^{30(12)}}{(1+\frac{0.06}{12})^{30(12)}-1}$

∴ $pmt=\frac{0.005[105000(1.005)^{360}]}{(1.005)^{360}-1} =629.528$

* The monthly mortgage payment is $629.53

A taxi in new york city charges a flat fee of $3.50, plus $0.75 for every mile traveled. How much would a 6 mile taxi ride cost?

REY [17]

So, you start off with $3.50 you travle 6 miles every mile is 0.75 that means you would need to multiply 6 by 0.75.

6
0.75
it equals 4.5

So we have $4.50 we need to add $3.50 and in total $0.50 plus $0.50 would be a dollar + 3 dollars plus $4 would be 7 so 7 +1 is 8. and 8 is the answer.

If a 100.8g cement bag has 20.35 kg removed from it. what is the new weight of the bag

kykrilka [37]

100.80 kg - 20.35 kg = 80.45 kg . . . . the new weight of the bag

It's a pretty straightforward subtraction problem. As with any decimal addition or subtraction, you line up the decimal points and extend any numbers with zeros to make the number of decimal places match.

Bill is bisecting an angle with technology Which of the following describes his next step?

maw [93]

Answer:

Mark point E where the circle intersects segment BC

Step-by-step explanation:

Apparently, Bill is using "technology" to perform the same steps that he would use with compass and straightedge. Those steps involve finding a point equidistant from the rays BD and BC. That is generally done by finding the intersection point(s) of circles centered at D and "E", where "E" is the intersection point of the circle B with segment BC.

Bill's next step is to mark point E, so he can use it as the center of one of the circles just described.

___

<em>Comment on Bill's "technology"</em>

In the technology I would use for this purpose, the next step would be "select the angle bisector tool."
