National Textile installed a new textile machine in one of its factories at a cost of $250,000. The machine is depreciated linea

kirill115 [55]

Answer:

The required expression is $y=250,000-24,000 t$

Step-by-step explanation:

Consider the provided information.

National Textile installed a new textile machine in one of its factories at a cost of $250,000.

That means for 0 year the cost of the machine is $250,000.

This can be written as: (0, 250,000)

Over 10 years with a scrap value of $10,000

That means for 10 year the cost of the machine is $10,000.

This can be written as: (10, 10,000)

Now first find the rate of change:

Rate of change=m= $\frac{Rise}{Run}=\frac{10,000-250,000}{10-0}$

Rate of change=m= $\frac{Rise}{Run}=\frac{-240,000}{10}$

Rate of change=m= $\frac{Rise}{Run}=-24,000$

Now use the point-slope form of an equation of a line with the point (0, 250,000), we can find the required expression.

$(y-250,000)=-24,000(t-0)$

$y-250,000=-24,000 t$

$y=250,000-24,000 t$

Hence, the required expression is $y=250,000-24,000 t$

(Please show your work) (1 kwh = 3400 BTU’s 1 gallon = 8 pounds of water) The water coming into a dishwasher from a water heater

shtirl [24]

Answer:

5700 BTU

Step-by-step explanation:

Data provided in the question:

1 kwh = 3400 BTU’s

1 gallon = 8 pounds of water

Initial temperature = 50°F

Final temperature = 100°F

Water used by dishwasher = 10 gallons

Electrical energy used = 0.5 kwh

Now,

Water used in pounds = 10 × 8 = 80 lb

Total electrical energy used in BTU = 0.5 × 3400 BTU [ as 1 kwh = 3400 BTU]

Total electrical energy used in BTU = 1700 BTU

Energy used by water = Water used by dishwasher × Change in temperature × Specific heat of water

[ Specific heat of water = 1 BTU / °F.lb ]

Thus,

Energy used by water = 80 × 1 × ( 100 - 50 )

= 4000 BTU

Hence,

Total energy used = 1700 BTU + 4000 BTU = 5700 BTU

The rule as a mapping for the translation of a rectangle is (x, y) → (x – 2, y + 7). Which describes this translation?

maksim [4K]

Answer:

The answer is a translation of 2 units to the left and 7 units up

Step-by-step explanation:

we know that

In the rule for the translation of a rectangle

(x, y) → (x – 2, y + 7).

the term (x-2) means a translation of 2 units to the left

the term (y+7) means a translation of 7 units up

Therefore,

The answer is a translation of 2 units to the left and 7 units up....

2. Rich wrote a novel that sells for n dollars each. He received a bonus of $50,000 to sign the

Yuki888 [10]

The equation which represent total amount of income he earns from selling book is, $A=50000+\frac{109}{100}bn$

Since, Selling price of one novel is n dollars

So, selling price of b books is, $n*b=nb$

Since, he receives 9% commission on each book sale.

So, total commission he receives on selling of b books is,

$nb*\frac{9}{100}=\frac{9}{100}nb$

And also he received a bonus of $50,000 to sign the contract to write the book,

So, total amount of income he earns is represented by A,

$A=50000+bn+\frac{9}{100}bn\\\\A=50000+\frac{109}{100}bn$
