Step-by-step explanation:
Pete's Convenience Store has a beginning inventory of 12 cans of soup at a cost of $.85 each. During the year, the store purchased 4 at $.95, 6 at $1.05, 7 at $1.35, and 8 at $1.50. By the end of the year, 18 cans were sold. Calculate (A) the number of cans of soup ending inventory and (B) the cost of ending inventory under LIFO, FIFO, and weighted average. (Round your final answers to the nearest cent.)
A) The number of unsold cans of soup (ending inventory) is 19.
B) The various costs of the ending inventory under LIFO, FIFO, and the weighted average are as follows:
Ending Inventory
LIFO $17.15
FIFO $25.65
Weighted average $21.47
How are the inventory methods different?FIFO assumes that the physical flow of goods sold should follow the chronological sequence of purchases or production.
LIFO assumes that the first goods acquired are the last to be sold.
The Weighted Average uses an average to determine the cost of ending inventory and the cost of goods sold.
Description Units Unit Cost Total
Beginning inventory 12 $0.85 $10.20
Purchases 4 $0.95 $3.80
Purchases 6 $1.05 $6.30
Purchases 7 $1.35 $9.45
Purchases 8 $1.50 $12.00
Total 37 $41.75
Sales 18
Ending inventory 19 (37 - 18)
Average cost = $1.13 ($41.75/37)
LIFO:
Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)
Cost of goods sold = $24.60 ($41.75 - $17.15)
FIFO:
Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)
Cost of goods sold = $16.10 ($41.75 - $25.65)
Weighted Average:
Ending inventory = $21.47 (19 x $1.13)
Cost of goods sold = $20.34 (18 x $1.13)

Answer:
A. x = 12, y = 11, z = 2
Step-by-step explanation:
\(x + y + z = 25\)
\(5x + y + 9z = 89\)
\( - 7x + 6y + 6z = - 6\)
Solve explicitly for 2 variables then substitute them into the third equation. Solving for x and z is a bit easier in this case.\(x = 25 - y - z\)
Substitute this in 5x + y + 9a = 89 then solve for z\(5(25 - y - z) + y + 9z = 89\)
\( - 5y + y - 5z + 9z = 89 - 125\)
\(4z - 4y = - 36\)
\( \frac{4z - 4y}{4} = \frac{ - 36}{4} \)
\(z = y - 9\)
Substitute both x and z into the third equation\( - 7(25 - y - (y - 9)) + 6y + 6(y - 9) = - 6\)
\( - 175 + 7y + 7y - 63 + 6y + 6y - 54 = - 6\)
\(26y - 292 = - 6\)
\(26y = 286\)
\(y = 11\)
Find z then find x by substituting the values you found.\(z = 11 - 9 = 2\)
\(x = 25 - 11 - 2 = 12\)
Values for x, y and z are:\(x = 12\)
\(y = 11\)
\(z = 2\)

A zoologist recorded the speed of two cheetahs. Cheetah A ran 17 miles in 8 minutes. Cheetah B ran 56 miles in 20 minutes. Which statement is correct?
Cheetah A has a higher ratio of miles per minute than Cheetah B because 17 over 8 is less than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is greater than 56 over 20.
Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is less than 56 over 20.
Both cheetahs have the same ratio of miles per minute.
The answer would be C - "Cheetah B has a higher ratio of miles per minute than Cheetah A because 17 over 8 is less than 56 over 20."

Solve the equation 25z2 − 140 = 29 by using square roots.
A. z = ±13/5
B. z = ±7/5
C. z = ±29/7
D. no real solutions
Answer:
Option A, \(z =\) ± \(13/5\)
Step-by-step explanation:
Step 1: Add 140 both sides
\(25z^2 - 140 = 29\)
\(25z^2 - 140 + 140 = 29 + 140\)
\(25z^2 = 169\)
Step 2: Divide both sides by 25
\(\frac{25z^2}{25} = \frac{169}{25}\)
\(z^2 = 6.76\)
Step 3: Square root both sides
\(\sqrt{z^2} = \sqrt{6.76}\)
\(z =\) ± \(2.6\)
\(z =\) ± \(13/5\)

Answer: See explanation
Step-by-step explanation:
1. Let the small number be x
Then, the bug number will be: x + 25
Therefore, x + x + 25 = 131
2x + 25 = 131
2x = 131 - 25
2x = 106
x = 106 / 2
x = 53
Small number= 53
Big number = x + 25 = 53 + 25 = 78
2. Let the small number be x
Then, the bug number will be: x + 14
x + x + 14 = 58
2x + 14 = 58
2x = 58 - 14
2x = 44
x = 44/2
x = 22
Small number = 22
Bug number = 22 + 14 = 36
The numbers are 22 and 36.
3. Let number of basketball sold be x
Therefore, number of football sold will be x+3.
Therefore, x + x + 3 = 27
2x + 3 = 27
2x = 27 - 3
2x = 24
x = 24/2
x = 12
12 basketball were sold
Number of footballs sold = 12 + 3 = 15
4. Let calories in bowl of soup x
Hamburger = 2 × x = 2x
Therefore, x + 2x = 738

x = 738/3
x = 246
There are 246 calories in bowl of soup
Calories in hamburgers = 246 × 2 = 492 calories

Find the missing angle and side measures of Delta*ABC , given that
m angle A = 50 deg , m angle C = 90 deg , and CB = 16
The missing angle is <B= 40 degree and missing side length is AB = 12.25 and AC = 19.068.
To find the missing angle and side measures of ΔABC, we can use the properties of a triangle.
Given:
∠A = 50°
∠C = 90°
CB = 16
We can start by finding the measure of ∠B:
∠A + ∠B + ∠C = 180° (Sum of angles in a triangle)
50° + ∠B + 90° = 180°
∠B + 140° = 180°
∠B = 180° - 140°
∠B = 40°
Now, using Sine law
CB/ sin A = AB / sin C
16 / sin 50 = AB / sin 90
16 / 0.766044 = AB
AB = 12.25
Again 12.25 = AC/ sin B
12.25 = AC / sin 40
AC = 19.068

A zip wire runs between two posts, 25m apart. The zip wire is at an angle of 10∘ to the horizontal. Calculate the length of the zip wire.
The length of the zip wire is approximately 25.42 meters.
To calculate the length of the zip wire, we can use trigonometry and the given information about the angle and the distance between the two posts.
Given:
Distance between the two posts: 25m
Angle of the zip wire to the horizontal: 10°
We can use the trigonometric function cosine (cos) to find the length of the zip wire. Cosine relates the adjacent side to the hypotenuse of a right triangle.
In this case, the adjacent side is the distance between the two posts (25m) and the hypotenuse is the length of the zip wire that we want to calculate.
Using the cosine function:
cos(angle) = adjacent/hypotenuse
cos(10°) = 25m/hypotenuse
To find the hypotenuse (length of the zip wire), we can rearrange the equation:
hypotenuse = 25m / cos(10°)
Using a calculator or trigonometric tables, we can find the value of cos(10°) to be approximately 0.9848.
Therefore, the length of the zip wire is:
hypotenuse = 25m / 0.9848 ≈ 25.42m

The population of a town increased from 3700 in 2005 to 5900 in 2009. Find the absolute and relative (percent) increase.
Absolute increase:
Relative increase:
%
The absolute increase in population is 2200, and the relative increase is approximately 59.46%.
To find the absolute and relative increase in population, we can use the following formulas:
Absolute increase = Final value - Initial value
Relative increase = (Absolute increase / Initial value) * 100%
Given the population in 2005 is 3700 and the population in 2009 is 5900, we can calculate the absolute and relative increase as follows:
Absolute increase = 5900 - 3700 = 2200
To calculate the relative increase, we need to divide the absolute increase by the initial value and then multiply by 100:
Relative increase = (2200 / 3700) * 100% ≈ 59.46%
Therefore, the absolute increase in population is 2200, and the relative increase is approximately 59.46%.
The absolute increase represents the actual difference in population count between the two years, while the relative increase gives us the percentage change relative to the initial value. In this case, the population increased by 2200 individuals, and the relative increase indicates that the population grew by approximately 59.46% over the given period.
Note that the relative increase is expressed as a percentage, which makes it easier to compare changes across different populations or time periods.

e^x=10^(x-1)
Answer:
Step-by-step explanation:
This equation represents the relationship between the exponential functions y = e^x and y = (10^(x-1)). These two functions are equal to each other for all values of x. This can be shown by taking the natural logarithm of both sides of the equation, which gives us:
ln(e^x) = x-1
In this equation, ln(e^x) is equal to x, since the natural logarithm of an exponential expression with a base of e is the exponent. Therefore, we can simplify the equation by taking the natural logarithm of both sides:
ln(10^(x-1)) = x-1
e^(x-1) = 10^x
The two functions e^x and 10^(x-1) are the same function with different bases, so they follow the same pattern. The fact that these two functions are equal to each other for all values of x can also be shown by graphing the two functions and seeing that they overlap perfectly.
