Answer: The guitar's value over time is described by the 0.95 metric, indicating a 5% annual depreciation.
Step-by-step explanation:
To address this inquiry, we use an exponential decay formula:
A = P (1 - r) t
Where:
P = initial price
r = the reduction rate (expressed as a decimal)
t = time in years
A = price after t years
Substituting the known values:
A(t)=145(0.95)t.
Where
0.95 = 1-r
0.95-1 = r
-0.05 = -r
0.05 = r
Converted to percentage:
0.05 x 100 = 5%

It takes 5.22 hours to install carpet in a room. Step-by-step explanation: To start, let's explore the relationship among yards, feet, and inches. 1. 1 yard = 3 feet. 2. 1 foot = 12 inches. 3. Therefore, 1 yard = 36 inches. Now, let's convert all measurements to inches. ∵ 1 yard = 36 inches ∴ 1 yard² = (36)² inches². - Fine Floors can outfit 15 square yards of carpeting in 4 hours and 30 minutes. ∵ 15 yard² equals 15 × (36)² inches², so 15 yards² = 19440 inches². ∵ 1 hour equals 60 minutes, thus 30 minutes = 0.5 hours. Consequently, 4 hours and 30 minutes = 4.5 hours, implying Fine Floors covers 19440 inches² in 4.5 hours. The dimensions of the room are 11 feet 9 inches by 13 feet 4 inches. ∵ 1 foot = 12 inches, therefore, 11 feet 9 inches = 11 × 12 + 9 = 141 inches, and 13 feet 4 inches = 13 × 12 + 4 = 160 inches. Hence, the room’s area is 141 × 160 = 22560 inches². Using the ratio method, we have area of carpeting (in²): time of carpeting (hr) hence, 19440: 4.5 = 22560: h. By cross-multiplying, 19440h = 4.5 × 22560 yields 19440h = 101520. Dividing both sides by 19440 results in h = 5.22 hrs.
Answer:
P=x/2.2
Step-by-step explanation:
We can set up an equation to solve this.
Let P represent the number of pounds
Let X represent the number of kilograms
Knowing that 1 kilogram equals 2.2 pounds.
So, if there is 1 kilogram (X) it translates to 2.2 pounds (P).
X=2.2P
Simply rearrange the equation to determine the pounds in x kilograms. Thus, divide both sides by 2.2.
Therefore, we derive P=x/2.2
