Answer: 7 hours 15 minutes, 6 hours 45 minutes, 5 hours 12 minutes, 6 hours 6 minutes

Step-by-step explanation:

7 1/4 hours = 7 hours + 1/4 × 60 = 7 hours 15 minutes

6 3/4 hours = 6 hours +3/4 × 60 = 6 hrs 45 mins.

5 1/5 hours = 5 hours + 1/5 × 60 = 5 hrs 12 mins.

6 1/10 hours = 6 hours + 1/10 × 60 = 6 hours 10 mins.

A four-door sedan costs$35000 with a residual value of $2000. Its service life is five years. Using the declining balance method
larisa [96]

Answer:

At the end of the 2 year, the book value of the truck is $12,600

Step-by-step explanation:

we know that

<u><em>Double declining balance method</em></u> is a form of an accelerated depreciation method in which the asset value is depreciated at twice the rate it is done in the straight-line method.

Step 1

Determine the straight-line depreciation rate

Divide the total cost by the number of years in the asset's useful life.

\frac{\$35,000}{5}=\$7,000

Step 2

Then, multiply that number by 2 and that is your Double-Declining Depreciation Rate

7,000(2)=\$14,000 -----> is the depreciation for Year 1

Step 3

At the end of the first year, the book value of the truck is

\$35,000-\$14,000=\$21,000

Step 4

For Year 2, we will apply the same formula to the book value of the truck by the end of Year 1

\frac{\$21,000}{5}=\$4,200

4,200(2)=\$8,400 -----> is the depreciation for Year 2

therefore

At the end of the 2 year, the book value of the truck is

\$21,000-\$8,400=\$12,600

The histogram presents the compressive strengths of a sample of concrete blocks hardened for 28 days.
dusya [7]

Answer:

The question is not complete but I have uploaded the image to complete the question.

The missing rectangle has a relative frequency of 0.15, and this is the same as the height.

Step-by-step explanation:

Let us define what a frequency and relative frequency are

The frequency of a datum is the number of times a given item (datum) appears in the data set.

While the relative frequency is the fraction or proportion of times taken from the whole in which an item/datum occurs.

So, from the image I uploaded, the relative frequency column represents the height of the histogram. Let the height of the missing rectangle be <em>x.</em>

Therefore the heights of the rectangles written from left to right are 0.05, 0.1, 0.15, <em>x, </em>0.25, 0.2, and 0.1.

From the definition of relative frequency, the total sum of relative frequency is 1, if represented as decimals or fractions it can either be expressed in percentage, or decimal (fractions). In this question, it is represented in decimal, and the sum of all the relative frequency is 1.

0.05 + 0.1 + 0.15 + <em>x </em>+ 0.25 + 0.2 + 0.1 = 1 ;

0.85+ <em>x </em>=1

Therefore, <em>x </em>= 1 - 0.85= 0.15

For 80 guests you will need 80/10 = 8 times more than for 10 guests:

8*9.50 = $76
