The volume of the bin is the amount of books it can contain.

455 books will fit in the bin

The dimension of the book is given as:

[tex]\mathbf{Book = 0.75ft, 0.75ft, 0.25ft}[/tex]

The dimension of the bin is given as:

[tex]\mathbf{Bin = 4ft, 4ft, 4ft}[/tex]

Start by calculating the volume of the book

[tex]\mathbf{Book = 0.75ft \times 0.75ft\times 0.25ft}[/tex]

[tex]\mathbf{Book = 0.140625ft^3}[/tex]

Next, calculate the volume of the bin

[tex]\mathbf{Bin = 4ft \times 4ft \times 4ft}[/tex]

[tex]\mathbf{Bin = 64ft^3}[/tex]

So, the number of books (n) is:

[tex]\mathbf{n = \frac{Bin}{Book}}[/tex]

This gives

[tex]\mathbf{n = \frac{64ft^3}{0.140625ft^3}}[/tex]

Cancel out the units

[tex]\mathbf{n = \frac{64}{0.140625}}[/tex]

[tex]\mathbf{n = 455.11}[/tex]

Remove the decimals

[tex]\mathbf{n = 455}[/tex]

Hence, 455 books will fit in the bin

Answer:2.11 aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer:

Step-by-step explanation:

1. & 2. & 3.  Direct Material Quantity Variance = (Planned Quantity - ActualQuantity) * Planned Price

Planned Quantity = 18,500 pounds

Actual Quantity = 18,800 pounds

Planned Price = $2.50

Direct Material Quantity Variance = (18,500-18,800)*$2.50

= - $750

Thus, the Direct Material Quantity Variance is $750 Unfavorable(As the actual quantity used is more than planned)

Answer:

Step-by-step explanation:

1. The material cost is the cost per pound multiplied by the number of pounds used.

  Planned material cost: (18,500 lb)($2.50 /lb) = $46,250

  Actual material cost: (18,800 lb)($2.54 /lb) = $47,752

  Material cost variance: $47,752 -46,250 = $1,502 . . . (unfavorable)

__

2. The material quantity is ...

  Planned: 18,500 lb

  Actual: 18,800 lb

  Material quantity variance: 18,800 -18,500 = 300 . . . pounds (unfavorable)

__

3. The direct labor rate is the labor cost divided by the labor hours.

  Planned labor rate: $16.50 per hour

  Actual labor rate: $360,000/(20,000 h) = $18.00 per hour

  Labor rate variance: $18.00 -16.50 = $1.50 . . . per hour (unfavorable)

The efficiency is assumed to be measured in units per hour of labor.

  Planned efficiency: (1 unit)/(0.5 h) = 2 units/h

  Actual efficiency: (45,000 units)/(20,000 h) = 2.25 units/h

  Efficiency variance: 2.25 -2.00 = 0.25 . . . units/h (favorable)

_____

Additional comment

Question 1 asks for the price variance, not the cost variance. The price is given in terms of dollars per pound. The variance in price per pound would be $2.54 -2.50 = $0.04 (unfavorable). We assumed the more interesting number is the cost variance, which takes into account the material quantity used.

Efficiency is usually measured in terms of useful output for a given input. For example, auto efficiency is measured in the US in terms of miles per gallon. Hence units per hour would be an appropriate efficiency measure. (Higher is better.)

In some instances, efficiency is measured in terms of the input required to obtain a given output. For example, auto efficiency is measured in metric countries in terms of liters per 100 kilometers. In that sense, the efficiency measure would be hours per unit. (Lower is better.)

Step-by-step explanation:

The 3 angles in a triangle sum up to 180° (Angle sum property of a triangle).

90° + 36° + (7x + 5)° = 180°

126 + 7x + 5 = 180

131 + 7x = 180

7x = 180 - 131

7x = 49

x = 49/7

x = 7

Answer:

x=7

Step-by-step explanation:

The sum of the angles of a triangle are 180

7x = 180-131

7x =49

The value of x is 23.78 cm and this can be determined by the cosine function.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given that a right triangle. The hypotenuse is labeled as 25 centimeters. The base is x.

Using the trigonometric functions the value of x can be determined. The cosine function can be used to determine the value of 'x'.

The cosine function is the ratio of the base to the hypotenuse.

Cos 18 = base /hypotenuse

Now, put the values of the base, hypotenuse, and the angle in the equation.

Cos 18 = x / 25

x = 23.78 cm

We assume you want the answer as a mixed number, since all of the problem numbers are given in that format.

Answer:

117, 118

Step-by-step explanation:

In order to find the pair of numbers with a sum of a number (x) whose product is maximum, you must find the numbers closest to half of x.

If the sum is odd, find the two numbers closest to half. If it is even, the largest product is half the sum multiplying itself.

In this case, with 235 being the sum, find the numbers closest to half of 235.

[tex]\frac{235}{2}[/tex] = 117.5

So, the closest numbers to half of 235 is 117 and 118.

The pair of numbers with a sum of 235 whose product is maximum is 117 and 118.
