Early in 2022, Pina Company switched to a just-in-time inventory system. Its sales revenue, cost of goods sold, and inventory amounts for 2021 and 2022 are shown below.
The Inventory Turnover for 2021 is 5.9 times and for 2022 is 10 times.
Inventory turnover2021
Inventory Turnover = Cost of Goods sold / Average Inventory
Cost of Goods sold = $1,165,250/[($170,000+$225,000)/2]
Cost of Goods sold = $1,165,250/($395,000/2)
Cost of Goods sold = $1,165,250/197,500
Cost of Goods sold = 5.9 times
2022
Inventory Turnover = Cost of Goods sold / Average Inventory
Cost of Goods sold = $1,525,000/[($225,000+$80,000)/2]
Cost of Goods sold = $1,525,000/($305,000/2)
Cost of Goods sold = $1,525,000/152,500
Cost of Goods sold = 10 times
Therefore the Inventory Turnover for 2021 is 5.9 times and for 2022 is 10 times.

The half life of the radioactive Rutherford-265 is;
13.1 hours.
What is the half-life of the radioactive Rutherford-265?It follows from the task content that the given function represents the decay function of the radioactive material. Since half-life corresponds to the point at which only half of the starting material remains, hence we have;
(1/2) = e ^(-0.053t)
By taking the natural log of both sides, we have;
-0.6931 = -0.053t
Hence, t = -0.6931/ -0.053 = 13.1 hours.

Zarko and Manchu are two ctas that like to catch fish in the pond in their backyard. Zarko can catch 5 fish evry hour, while manchu can catch 2 fish every half an hour. How long did it take them to catch 27 fish in all,
It takes 3 hours for the cats to catch 27 fish in the pond.
How long did it take them to catch 27 fish in all?Zarko can catch 5 fish per hour.
Manchu can catch 2 fish every 0.5 of an hour, so in an hour, the cat would catch 2 times that, which is 4 fish.
When working together, the cats can catch 4 + 5 = 9 fish per hour
If the cats work for x hours, then they catch 9*x fish.
To get the time that takes them to catch 27 fish we just need to solve the linear equation:
9x = 27
Solving for x:
x = 27/9 = 3

5. Kal Tire installs automobile tires on a first-come first-served basis. A random sample of 50 customers experienced an average wait time of 93.7 minutes. Assume that the standard deviation of total wait time for all customers is 20.6 minutes. Determine the margin of error for a 95% confidence interval for this sample.
5.7099 is the margin of error.
What is standard deviation ?
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.
Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
According to the question,
The standard sampling error of the sample mean is σₓ ,
The sampling distribution is: N (u,σₓ/n)
Therefore,
By using the standard deviation formula:
σₓ = √∑(xi -μ)/N
Where,
∑= population standard deviation
N= the size of the population
xi= each value from the population
μ =the population mean
So ,
σₓ = [tex]\frac{20.6}{\sqrt{50} }[/tex] = 2.913
Since, a = 1- 95% = 0.05
therefore [tex]Z\frac{a}{2}[/tex] = (1-0.005 x 2) = 1.959964
Here, the margin of error for a 95% confidence interval for this sample is given by:
[tex]Z\frac{a}{2}[/tex] * σₓ = 1.959964 x 2.913
= 5.7099

Compare the process of solving |x – 1| + 1 < 15 to that of solving |x – 1| + 1 > 15. Check all of the following you included in your response. Both absolute values would need to be isolated first. You would need to write a compound inequality for each. Both compound inequalities would compare x – 1 to –15 and 15. The inequality with “<” would use an “and” statement, while the “>” would use an “or” statement.
The required Comparison of the inequalities are
The |x – 1| + 1 > 15 represents the value of x lies between 13<x<15.The range of values encompassing the region's junction is (-13, 15).
If x is more than or equal to 15, then x-11+1>15 indicates the value of x is greater than or equal to 13. None of the regions in the intersection are empty.What is inequality?When comparing two numbers, an inequality indicates whether one is less than, larger than, or not equal to the other.
We take into account the various variables of the inequality
|x – 1| + 1 > 15
Therefore
|-x-1|+1-1<15-1
|-x-1|-1 <14
13<x<15
The required region lies between the inequality -13 <x< 15.
Simplify the inequality Ix-11+1 > 15 we get,
|x-1|+1 > 15
|x+1| +1-1 >15-1
|x-1| > 14
x> 15

If x has a value between -13 and x + 15, then the expression "|x-1|+1+115" is true. The range "(-13, 15)" contains the intersection of the region.If "|x-1|+1>15" then either "x >15" or "x-13" applies to the value of x. This region's intersection is unoccupied.Read more about inequalities

We have an exponential growth. The domain is the set of all real numbers and the range is R: (0, ∞).
What can we say about the exponential function?Here we have the exponential function:
[tex]h(x) = 125^x[/tex]
Notice that the base, 125, is larger than 1, which means that we have an exponential growth.
So, as x increases, also does h(x).As x decreases, also does h(x).Now, the domain of any exponential equation is the set of all real numbers.
For the range, as x tends to negative infinity, the function will tend to zero.
And as x tends to infinity, h(x) also tends to infinity.

MATH: FINDING HALF LIFE PT 1
Answer:
15.4 years
Step-by-step explanation:
An investment is doubled when it is twice its initial value. The equation can be solved for the value of t that makes this true.
SetupIn the exponential equation for investment value, the factor y₀ is the initial value of the investment. We want to find t when y = 2y₀.
2y₀ = y₀·e^(0.045t)
SolutionDividing by y₀ gives ...
2 = e^(0.045t)
Taking natural logarithms, we have ...
ln(2) = 0.045t
Dividing by the coefficient of t gives its value:
t = ln(2)/0.045 ≈ 15.4
The investment will be doubled after 15.4 years.
__
Additional comment
The continuously compounded interest rate for this investment is 4.5%. The doubling time is 0.693 divided by this: 0.693/0.045 ≈ 15.4. This relationship holds for any sort of continuous compounding.

[<Answer>] (2):
Hello! I'm Avery. And I'm here to help! :)
----------------------------------------------------------------------------------------------------------
[<The Explanation>}:
Sally has pet snail that fell into a well.
(Depth of the well = 16 feet)
Snail climbs up 5 feet but each night it slides back down 4 feet.
So the snail climbs up per day = 5 feet - 4 feet = 1 feet.
Number of days snail took to reach at 11 feet = 11 × 1 = 11 feet
Remaining distance to cover by the snail = 16 - 11 = 5 feet
Number of days to cover remaining 5 feet to reach the top of the well = 1 day
Therefore, snail will take 12 days to reach the top of the well.

Step-by-step explanation:
let x be the measure of the angle of elevation of the sun.
tan(x) = 10/14

x = tan⁻¹ (10÷14) = 35.537677791974°
………………………………………………
let y be the measure of the angle of elevation of the sun
where the shadow decreases to 5m.

Answer:
a) 35.54°
b) 63.43°
Given following:
length of pole: 10 meterits shadow: 14 meterDetermining, the shadow is adjacent side and length of the pole is the opposite side. Hence, use the tan rule. Let the angle be x.
(a)
[tex]\sf tan(x) = \dfrac{opposite}{adjacent}[/tex]
[tex]\sf tan(x) = \dfrac{10}{14}[/tex]
[tex]\sf x = tan^{-1}(\dfrac{10}{14} )[/tex]
[tex]\sf x = 35.54^{\circ \:} \quad (rounded \ to \ nearest \ hundredth )[/tex]
(b) If the shadow decreases to 5 meter.
[tex]\sf tan(x) = \dfrac{opposite}{adjacent}[/tex]
[tex]\sf tan(x) = \dfrac{10}{5}[/tex]
[tex]\sf x = tan^{-1} (\dfrac{10}{5})[/tex]
