Answer:

Karson's average speed on his way home was 28 miles per hour.

Step-by-step explanation:

Since Karson drove from his house to work at an average speed of 35 miles per hour, and the drive took him 20 minutes, if the drive took him 25 minutes and he used the same route in reverse, to determine what was his average speed going home, the following calculation must be performed:

60 = 35

20 = X

20 x 35/60 = X

700/60 = X

11.666 = X

25 = 11,666

60 = X

60 x 11.666 / 25 = X

27.99 = X

Therefore, Karson's average speed on his way home was 28 miles per hour.

Bogle Company purchased machinery for $320,000 on January 1, 2014. Straight-line depreciation has been recorded based on a $20,0
horrorfan [7]

Answer:

$66,000

Step-by-step explanation:

Data provided in the question:

Purchasing cost of the machine = $320,000

Salvage value = $20,000

Useful life of the machine = 5 years

The gain on selling of the machine = $6,000

Now,

The annual depreciation of the machine

= [Cost - salvage value] ÷ ( Useful life )

= [ $320,000 - $20,000 ] ÷ 5

= $60,000

Accumulated depreciation from January 1, 2014 to May 1, 2018

= Annual depreciation ×  (Duration from January 1, 2014 to May 1, 2018 )

= $60,000 × ( 4 years 4 months )

= $60,000 × \frac{52}{12} years      

[48 months + 4 months = 52 months]

= $260,000

Therefore,

Book value on May 1, 2018 = Cost - Accumulated depreciation

= $320,000 - $260,000

= $60,000

Now,

Gain = Selling cost - Book value

$6,000 = Selling cost - $60,000

or

Selling cost = $66,000

Hence,

cash Bogle received from the sale of the machinery was $66,000

Amanda bought g gallons of paint for $16.55 per gallon and t pints of paint thinner for $5.97 per pint. Write an expression to r
Neporo4naja [7]

Answer:

total \ cost =16.55(8) +5.97(3)=150.31

Step-by-step explanation:

Amanda bought g gallons of paint for $16.55 per gallon and t pints of paint thinner for $5.97 per pint

Total amount = rate per gallon times gallons + rate per pint times  pints

total amount =16.55 g +5.97 t

amanda bought 8 gallons of paint and 3 pints of paint thinner

g=8 and t=3, substitute the values and find total cost

total \ cost =16.55(8) +5.97(3)=150.31

Each week, Allen earns $70 for every shift he works at the diner and $12 for every dog-walking job. He uses the expression 70x +
Gwar [14]

Answer:

  A. coefficients: 70, 12; variables: x, y.

  B. 2 terms: 70x, 12y; separated by an addition symbol

  C. 70x

Step-by-step explanation:

We will answer the questions in the context of this problem. In other problems, the meaning of "coefficient", "variable", and "term" may be different.

__

A. The coefficients are the numbers; the variables are the letters. Then the coefficients are 70 and 12; the variables are x and y.

__

B. Each product is a term. Terms are separated by the + sign. There are two terms in this expression, one on either side of the + sign. When an expression is written with no parentheses, the terms are separated by + or - signs. (Often, we think of the minus sign as being part of the coefficient of the term. Then we can say terms are separated by + signs. 10x + (-32y), for example.)

__

C. When you match the coefficients to the numbers in the problem statement, you see that the number matching the earnings at the diner is <em>$70 per shift</em>. If we assume that x represents the number of shifts worked at the diner, then the term 70x will represent the total earned from the diner. It is the product of the earnings per shift and the number of shifts.
