A property sells for $140,000 two years after it was purchased. If the annual appreciation rate is 6%, how much did the original buyer pay for it?

Answers

Answer:

$123,200

Step-by-step explanation:

0.06 x 2 = 0.12

140,000 x 0.12 = 16,800

140,000 - 16,800 = 123,200

The original buyer paid the amount of $123,200 for the property.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

The property appreciated by 6% per year, so in two years it would have appreciated by 6% × 2 years = 12%.

Once we know the total appreciation, we can subtract that value from 100% to find the original purchase price as a percentage of the final sale price.

If the property appreciated by 12%, then the original purchase price must have been 100% - 12% = 88% of the final sale price.

Now, multiply the final sale price by the original purchase price as a percentage to find the original purchase price.

So, the original buyer paid the amount = 88% × $140,000 = $123,200

Therefore, the original purchase price was $123,200.

Saji swims 1/3 mi every day. One day he had already swum 1/5 mi. How much further should he swim?

Answers

9514 1404 393

Answer:

  2/15 mi

Step-by-step explanation:

The difference of two fractions can always be computed using the pattern ...

  [tex]\dfrac{a}{b}-\dfrac{c}{d}=\dfrac{ad-bd}{bd}[/tex]

Using this pattern to find the difference of 1/3 and 1/5, we see it is ...

  1/3 -1/5 = (5 -3)/(3·5) = 2/15

Saji must swim 2/15 miles further to complete his 1/3 mile swim.

Step-by-step explanation:

The two given points are (x, C) = (60, 40) and (170, 50). These can be used in the 2-point form of the equation for a line to find the cost function.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (50 -40)/(170 -60)(x -60) +40

  y = (1/11)(x -60) +40

Draw a line segment of length 6.4 cm and divide it in to 4 equal parts. Write the length of each part. (Draw clearly) ​

Answers

Answer:

The line drawn has a length of 6.4 cm.

Also it is divided into 4 equal parts.

Hence let the measure of the each equal part be ' x '

So x * 4 parts = 6.4 cm

=> x = 6.4 cm / 4

=> x = 1.6 cm

Hence the measure of each equal part is 1.6 cm.

Hence solved !

the line y=mx+7 is perpendicular to the line y=3/4x-9. what is the value of m?

Answers

Answer:

-4/3

Step-by-step explanation:

In y=mx+b, m represents the slope. In the second line, we are multiplying x by (3/4). This represents the slope of the second line.

To find the slope of a perpendicular line, we take the negative reciprocal of the current slope. In the first line, m represents the slope. The reciprocal of 3/4 is 4/3, and the negative reciprocal of 3/4 is -4/3. This is the value of m

Ronnie sales wooden toothpicks it cost him $.10 to make a box of toothpicks he charges $1.20 per box toothpicks how many toothpicks does he need to sell to profit $1000

Answers

Answer:

910 boxes of toothpicks

Step-by-step explanation:

Create an equation to represent the situation, and let x represent the number of boxes of toothpicks.

1.20x - 0.1x = 1000

1.1x = 1000

x = 909.09

Round up to the nearest whole number:

= 910

So, Ronnie would have to sell 910 boxes of toothpicks to profit $1000.
