Deep Blue, a deep sea fishing company, bought a boat for $250,000. After 9 years, Deep Blue plans to sell it for a scrap value o
Leona [4166]

Answer:

Hence, utilizing linear depreciation gives us 17222.22.

Step-by-step explanation:

The boat's initial value is noted to be $250,000.

The straight-line depreciation method for calculating a boat is as follows:

Cost of the boat is $250,000.

Deep Blue anticipates selling it for $95,000 after 9 years.

Employing the formula, we calculate:

(250000-95000)/9=155000/9=17222.22

Thus, the outcome using linear depreciation is 17222.22.

A salesperson has to drive 500 miles. For the first three hours she drove at 65 mi/h. For the next two hours she drove at 55 mil
AnnZ [3877]
       Short answer: 195
First, you multiply 65 by 3, yielding 195 miles.
Then, multiplying 55 by 2 gives you 110 miles.

By summing both distances, you arrive at 305.
From 500, if you subtract 305, you find =195.

The market price of a house is directly proportional to the total area of the house in square feet. If the price of a 1,500 squa
zzz [4022]

Answer:

The cost for a 2,000 square foot house is \$400,000

Detailed explanation:

Recall that if two variables x and y vary directly, the relationship can be written as y/x=k or y=kx.

Define:

x as the house area in square feet

y as the price of the house

Given point (1500, 300000)

Calculate proportionality constant k:

k=y/x

Insert values:

k=300,000/1,500=200

The direct variation equation is:

y=200x

For x = 2000:

Calculate y:

Replace x in equation:

y=200(2,000)

y=\$400,000

(Please Hurry!) Which expression is equivalent to the following complex fraction?
lawyer [4008]

Answer:

The equivalent expression for the provided complex fraction is

\frac{-2x+5y}{3x-2y}

Step-by-step explanation:

To simplify the complex fraction, calculating the numerator and denominator individually is effective.

Numerator:

\frac{-2}{x} + \frac{5}{y}\\ = \frac{-2y + 5x}{xy}

Denominator:

\frac{3}{y} + \frac{-2}{x}\\ = \frac{3x - 2y}{xy}

Resolving the complex fraction:

[\frac{-2}{x} + \frac{5}{y}] / [\frac{3}{y} + \frac{-2}{x}]\\= [\frac{-2y + 5x}{xy}] / [\frac{3x - 2y}{xy}]

=\frac{-2y + 5x}{xy} * \frac{xy}{3x - 2y}

Common terms in the numerator and denominator will cancel out (Cross multiplication):

= \frac{-2y + 5x}{3x - 2y}
