A) The number of cans of soup in ending inventory is 19.

B) The cost of the ending inventory under LIFO, FIFO, and the weighted average is as follows:

LIFO                                  $17.15

FIFO                                 $25.65

Weighted average          $21.47

The inventory methods include First-in, First-out (FIFO), Last-in, First-out (LIFO), Weighted Average, and Specific Identification.

FIFO assumes that the physical flow of goods during sales follows the chronological sequence of their acquisition.

LIFO assumes that the first goods acquired are the last to be sold.

The Weighted Average uses an average to determine the costs allocated to ending inventory and the cost of goods sold.

Specific Identification identifies the specific goods sold with their costs.

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)

FIFO:

Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)

Weighted Average

Ending inventory = $21.47 (19 x $1.13)

If on the third day, she earns three times as much as the second day. The amount that she earn on the first day is $856.

Let  a = Amount earned on the first day

Let b = Amount earned on the second day

Let c = amount earned on the third day

Let a + b + c =2568,

Hence,

2b + b +3b =2568

6b =2568

b =2568/6

b =428 second day

So,

a = 2b

a =2(428)

a =856 first day

Thus

c = 3b where b = 428

c=3(428)

c=1284 third day

Check:

a +b + c = $2568

856 + 428 + 1284 = $2568

The pitcher that has the lowest number of runs allowed per inning is Randy.

In order to determine the pitcher with the lowest number of runs per innings, divide the number of runs of each player by the number of innings of that player.

Division is the process of determining the quotient of two or more numbers. It is the process of putting a number into equal groups using another number.

Number of runs per innings = number of runs / number of innings

Number of runs per innings for Randy : 2 / 3 = 0.667

Number of runs per innings for Felix : 4 / 5 = 0.80

Number of runs per innings for Johan: 5 / 7= 0.714

Here is the complete question:

The total distance traveled by the patient in 1 hour and 10 minutes is 10.6 kilometers.

The distance is the length from one point to the end.

For our purpose, distance represents the product of speed and time.

Diameter of the bicycle's wheel = 590 mm

Speed (Revolutions) per minute = 82 rpm

Time riding the bicycle = 1 hr and 10 minutes = 70 minutes

1 Kilometer = 1,000,000 Millimeters

Distance per rotation = pi x diameter

= 3.14 x 590

= 1,852.6 mm/minute

Total distance traveled in kilometers = (1,852.6 x 82 x 70) ÷ 1,000,000

= 10,633,924 ÷ 1,000,000

The pH of the liquid which is 3.886 indicates that it is more acidic than coffee.

The pH of a solution gives a measure of the concentration of hydronium ions in the solution, and therefore, indicates the level of acidity or basicity of the solution.

pH values ranges from 0 to 14, with solutions that are more acidic having a pH of less than 7, while basic solutions have a pH of more than 7.

The given pH of coffee = -4.886

The concentration of the liquid = 10 × The concentration of the ions in coffee

If the triangle is equilateral then the sum of any two interior angles is same otherwise, with any isosceles triangle, we get different sums and therefore the friend is wrong.

Answer:

No.

Step-by-step explanation:

An isosceles triangle has two sides of equal length.  Therefore, only two of its interior angles are congruent.

The exterior angle of a triangle is equal to the sum of the two opposite interior angles (remote interior angles).  Therefore, as not all of the three interior angles of an isosceles triangle are congruent, all the exterior angles will also not be congruent.

In a case where the expression is give as volume V of a fixed amount of a gas varies directly as the temperature T and inversely as the pressure P, then the pressure will be 7kg/cm^2.

V = k T/ P

and V= 70 cm^3

T = 420 kelvin

P = 18 kg/cm^2

where K is constant of proportionality,

70 =( k * 420) / 18

k = (70 * 18) / 420

k= 3

Then we were given that the pressure=?

T = 140 kelvin

Answer:

Step-by-step explanation:

You want to know whether the pairs of equations describe lines that are parallel, perpendicular, or neither.

Parallel lines have the same slope. When the equations are written in slope-intercept form, the coefficients of x are identical.

Perpendicular lines have opposite reciprocal slopes. When the equations are written in slope-intercept form, the product of the x-coefficients is -1.

Solving the first equation for y gives ...

  y = 2x +2

The x-coefficients are 2 and -2, so the lines are neither parallel nor perpendicular.

Solving the first equation for y gives ...

  y = 2/4x -1 = 1/2x -1

The x-coefficients are 1/2 and -2, which have a product of -1. These lines are perpendicular.

Solving the second equation for y gives ...

  y = 2x -7/2

The x-coefficients are 2 and 2, which are identical. These lines are parallel.
