Answer:

1. The number is 71.3

2. The number is 127.1

3. The number is 230

4. The number is 34

Step-by-step explanation:

Let's find out the numbers, x, for each case:

1. 5% of it is 5% of it is 23% of 15.5

5% = 0.05

23% of 15.5 = 0.23 * 15.5 = 3.565

Then, we have:

0.05x = 3.565

x = 3.565/0.05

x = 71.3

The number is 71.3

2. 4% of it is 31% of 16.4

4% = 0.04

31% of 16.4 = 0.31 * 16.4 = 5.084

Then, we have:

0.04x = 5.084

x = 5.084/0.04

x = 127.1

The number is 127.1

3. 4.5% of it is 23% of 45

4.5% = 0.045

23% of 45 = 0.23 * 45 = 10.35

Then, we have:

0.045x = 10.35

x = 10.35/0.045

x = 230

The number is 230

4. 5.5% of it is 17% of 11

5.5% = 0.055

17% of 11 = 0.17 * 11 = 1.87

Then, we have:

0.055x = 1.87

x = 1.87/0.055

x = 34

The number is 34

HELP 30 POINTS!!!!!

Tamiku [17]

by pythagorean formula, the last side is √(61)

by cos rule

cos A

$= \frac{ {6}^{2} + 61 - {5}^{2} }{2 \times 6 \times \sqrt{61} } \\ = \frac{72}{12 \sqrt{61} } \\ = \frac{6}{ \sqrt{61} }$

A = 39.81

What is the rise over run for the slope -11/9

Igoryamba

Answer: 11 down and 9 right

Step-by-step explanation:

Slope IS rise over run where the top number of the fraction (numerator) determines the vertical distance --> positive is up, negative is down

and the bottom number of the fraction (denominator) determines the horizontal distance --> positive is right, negative is left.

Given slope = -11/9

the numerator is -11 so the "rise" is DOWN 11 units

the denominator is 9 so the "run" is RIGHT 9 units

Accounting procedures allow a business to evaluate their inventory costs based on two methods: LIFO (Last In First Out) or FIFO

ivanzaharov [21]

Answer: The FIFO method result in lower cost of inventory than the LIFO method.

Step-by-step explanation:

In the FIFO method old inventories are used to determine cost of goods sold (COGS), which result to less income because COGS is lesser, while it is greater in LIFO.

However, in LIFO, old and outdated inventories are valued lower than the present price. It not a good indicator of ending inventory value.

B. To calculate the degree of freedom of the inventory sample given: 1. 225221, 2. 119100, 3. 100113, 4. 212200, 5. 248245.

STEP 1. Find the mean or average of the samples.

Let x be the sample average, and N the sample size which is 5

x = 225221 + 119100 + 100113 + 212200 + 248245/5 = 180975.8

STEP 2. Degree of freedom Df is given as Df = N - 1

Remember, N is the sample size given as 5.

Df = 5 - 1 = 4.

CONCLUSION:

This shows that four numbers from the samples given have the freedom to vary as long as the average remains 180975.8.
