Question:

The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate their unit rate in miles per hour?

Answer:

$\frac{3/5}{3/8} = 1 \frac{3}{5}$ mile per hour

Explanation:

Given

Distance = 3/5 mile

Time = 3/8 hour

Required

Equation to calculate their unit rate in miles per hour?

To get the equation to calculate their unit rate in miles per hour, follow the steps below;

Step 1: Determine what miles per hour represent;

We know that mile is a measure of distance and hour is a measure of time.

The ratio of these two is a measure of speed.

Hence, the question can be interpreted as write an equation to calculate their speed

Step 2: Calculate their speed

We can calculate speed using the following formula

$Speed = \frac{Distance }{Time}$

By Substitution

$Speed = \frac{3/5}{3/8}$

The above expression is the equation that can be used to calculate their unit rate in miles per hour (in other words, their speed)

Solving this expression, we have

$\frac{3/5}{3/8} = \frac{3}{5} / \frac{3}{8}$

Convert division to multiplication

$\frac{3/5}{3/8} = \frac{3}{5} * \frac{8}{3}$

$\frac{3/5}{3/8} = \frac{8}{5}$

Convert to mixed fraction

$\frac{3/5}{3/8} = 1 \frac{3}{5}$

Hence, the expression is $\frac{3/5}{3/8} = 1 \frac{3}{5}$ mile per hour

You have the following information for Waterway Industries for the month ended October 31, 2022. Waterway uses a periodic method

Sidana [21]

Answer:

Waterway Industries

A) The weighted-average cost is $28.527

B) Ending Inventory, cost of goods sold, gross profit:

(1) LIFO (2) FIFO (3) Average-cost

Ending Inventory: $2,660 $3,060 $2,853

Cost of goods sold: $7,895 $7,495 $7,702

Gross profit: $3,780 $4,180 $3,973

Explanation:

a) Data and Calculations:

Date Description Units Unit Cost Selling Price Total

Oct. 1 Beginning inventory 70 $26 $1,820

Oct. 9 Purchase 125 28 3,500

Oct. 11 Sale (95) 40 $3,800

Oct. 17 Purchase 95 29 2,755

Oct. 22 Sale (70) 45 3,150

Oct. 25 Purchase 80 31 2,480

Oct. 29 Sale (105) 45 4,725

Oct. 31 Ending inventory 100

Total: Goods available 370 $10,555

Goods sold 270 $11,675

Weighted-average cost = Cost of goods available/Units available

= $10,555/370 = $28.527 per unit

Periodic method:

LIFO:

Ending inventory:

Oct. 1 Beginning inventory 70 $26 $1,820

Oct. 9 Purchase 30 28 840

Total Ending inventory = 100 $2,660

Cost of goods sold = Cost of goods available - Ending inventory

= $10,555 - $2,660 = $7,895

Sales Revenue $11,675

Cost of goods sold 7,895

Gross profit $3,780

FIFO:

Ending inventory:

Oct. 17 Purchase 20 29 $580

Oct. 25 Purchase 80 31 2,480

Total Ending inventory = 100 $3,060

Cost of goods sold = Cost of goods available - Ending inventory

= $10,555 - $3,060 = $7,495

Sales Revenue $11,675

Cost of goods sold 7,495

Gross profit $4,180

Average-cost:

Ending Inventory = $2,853 ($28.527 * 100)

Cost of goods sold = Cost of goods available - Ending inventory

= $10,555 - $2,853 = $7,702

Sales Revenue $11,675

Cost of goods sold 7,702

Gross profit $3,973

Assuming a FICA tax rate of 7.65% on the first $127,200 in wages, 1.45% on amounts in excess of $127,200, and a federal income t

Lelechka [254]

Answer:

$154524

Explanation:

If a federal tax rate is 20% on all wages then we subtract that amount from the total wage of $206000 for the year

20% from $206000 is $41200

$206000 - $41200 = $164800

We have deducted the federal tax rate and got the amount $164800

After we apply the FICA tax rate of 7.65% on the amount $127200 we get

7.65% of $127200 is $9730,8 so the first amount we have to remember is

$127200 - $9370,8 = $117469,2

Regarding the amount that excess $127200 that amount stands at

$164800 - $127200 = $37600

We apply the 1.45% rate to the amount $37600

1.45% of the $37600 is $545,2 so the second amount we have to remember is

$37600 - $545,2 = $37054,8

We now simply add the two calculated amounts

$117469,2 + $37054,8 = $154524

So the net pay for the year is $154524

If $13,300 is invested at 3.7% interest compounded semi-annually, how much will the investment be worth in 18 years?. . A.$25,73

Alla [95]

Principal (P) = $13300
Rate of interest (r) = 3.7%
Number of times compounded in a year (n) = 2
Number of years (t) = 18 years
Then
Amount = P(1 + r/n)^nt
= 13300[1 + (0.037/2)]^36
= 13300[1 + 0.0185]^36
= 13300(1.0185)^36
= 13300 * <span>1.9346
= 25730.54 dollars
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or option "C".</span>
