Answer:

2.5

Step-by-step explanation:

You must ensure your fractions have common denominators. For this equation you must convert 2/3 into something over 6, so you will multiply 2/3 by 2 and end up with 4/6.

7-4=3, and 1/6-4/6=-3/6

3(18/6)-3/6=2.5(15/6) or if you have paper and pencil just subtract normally.

7 1/6-4 4/6=2 3/6, or 2.5

Answer:

$2\frac{1}{2}$

Step-by-step explanation:

7-4=3

now let's change the denominator by finding the lcd (lowest common denominator)

factors of 3: 3, 6, 9, 12...

factors of 6: 6, 12, 18, 24...

both 3 and 6 has 6 as their lcd

3 x 2= 6

1/6 -4/6= -3/6

REDUCE

-1/2

3-1/2

2 1/2

Solve this system of linear equations. separate x and y values with a comma. 7x=-67-11y 5x=-73-11y

Aleks [24]

Answer:

3, -8

(x is equal to 3 and y is equal to -8)

Step-by-step explanation:

The system:

{ 7x=-67-11y

{ 5x=-73-11y

Finding a value for x:

7x=-67-11y -> x = $-\frac{67}{7}$ - $\frac{11y}{7}$

Solving for y by plugging in our x:

[Equation] 5x = -73 -11y

[Plug-in] 5( $-\frac{67}{7}$ - $\frac{11y}{7}$ ) = -73 -11y

[Distribute the 5] $-\frac{335}{7}$ - $\frac{55y}{7}$ = -73 -11y

[Multiply by 7] 7 ( $-\frac{335}{7}$ - $\frac{55y}{7}$ ) = (-73 -11y) 7

[Simplify] -335 - 55y = -511 - 77y

[Add 335 and 77y to both sides] 22y = -176

[Divide by 22] y = -8

Plug in our y to solve for x:

5x = -73 -11y

5x = -73 -11(-8)

5x = -73 + 88

5x = 15

x = 3

Have a nice day!

A right prism has a base that is an equilateral triangle. The height of the prism is equal to the height of the base. If the vol

Romashka [77]

Answer:

Lengths of the sides (there are 3 sides in an equilateral triangle) of the base of prism is 5.72cm each.

Step-by-step explanation:

As the base of triangular prism is equilateral:

∴ Area of base = (√ 3 / 4)× (side)²

According to question:

height of prism = height (side) of base

Volume of prism = 81 cm³,

∴ Volume of prism = Area of base x height

⇒ 81 cm³ = (√ 3 / 4)× (side)² × height ∵ side = height

⇒ 81 cm³ = (√ 3 / 4)× (side)³

⇒ 81 × (4/√3) cm³ = side³

⇒ ∛(81 × (4/√3) cm = side

⇒ side = 5.72cm

Miller Company’s total sales are $123,000. The company’s direct labor cost is $14,760, which represents 30% of its total convers

lana66690 [7]

Direct labor cost = $14760

This is 30% of total conversion cost so, conversion cost = 14760/30%

= $49200

Total conversion cost = Direct labor + Manufacturing overhead

Manufacturing overhead = Total conversion cost - Direct labor

=49200-14760 = $34440

Hence, The total manufacturing overhead cost= $34440

Direct labor = $14760

This is 40% of prime cost. So total prime cost = 14760/40%

= $36900

Total prime cost = Direct material + Direct labor

Direct material = Total prime cost - Direct labor

= 36900 - 14760 = 22140

Hence, the total direct materials cost = $22140

Total manufacturing cost = Direct materials + Direct labor + Manufacturing overhead

= 22140+14760+34440 = $71340

Variable selling and administrative cost = 5% of 123000

=$ 6150

Total variable cost = Direct materials + Direct labor + Sales commission

= 22140 + 14760 + 6150 =$43050

Fixed selling and administrative expense = Total selling and administrative expense - Sales commission = 18450-6150 = $12300

Total fixed cost = Manufacturing overheads + Fixed selling and administrative expense

= 34440+12300 = $46740

Total contribution margin = Sales - Total variable cost

= 123000 - 43050 = $79950
