Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de l
Setler79 [48]

Answer:

En la primera habitación son usadas 1200 baldosas.

En la segunda habitación son usadas 600 baldosas.

Sobraron 200 baldosas.

Step-by-step explanation:

Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.

Para la primera habitación se han gastado \frac{3}{5} de las baldosas. Esto se expresa como:

\frac{3}{5}*2000

Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción \frac{n}{1}. Luego se multiplica los numeradores y denominadores. En este caso:

\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}

Para reducir la fraccion, divide 40 entre 10

\frac{6000}{5} = 6000 ÷5= 1200

Entonces <u><em>en la primera habitación son usadas 1200 baldosas.</em></u> Por lo que las que quedan se calcula como:

2000 - 1200= 800 baldosas

De esta cantidad de baldosas que quedaron, \frac{3}{4} son usadas para embaldosar la segunda habitación.  Esto se expresa como:

\frac{3}{4}*800

Resolviendo de igual manera que en el caso de la primer habitación se obtiene:

\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}= 2400 ÷ 4= 600

Entonces <u><em>en la segunda habitación son usadas 600 baldosas.</em></u> Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:

800 - 600= 200 baldosas

<u><em>Sobraron 200 baldosas.</em></u>

You pay 5.65% on the first 110,000 of income and 1.45% in excess of $110,000. Calculate the FICA tax for an employee who earns 6
Y_Kistochka [10]

Answer:

The FICA tax for an employee who earns 60,000 a year is $ 3,390.

Step-by-step explanation:

Given that you pay 5.65% on the first 110,000 of income and 1.45% in excess of $ 110,000, to calculate the FICA tax for an employee who earns 60,000 a year the following calculation must be performed:

60,000 <110,000

60,000 x 0.0565 = X

3,390 = X

Therefore, the FICA tax for an employee who earns 60,000 a year is $ 3,390.

Answer:

           \large\boxed{\large\boxed{\$ 17.60/hour}}

Explanation:

The <em>profit</em> will be the revenue less the cost.

The revenue will be the price times the number of items sold. <em>The price is $40 the piece</em>. Work with a piece.

  • Revenue = $40

The total cost of a piece is the sum of the <em>cost of the supplies</em>, the s<em>eller's fees</em> and the <em>shipping costs</em> of a piece:

  • Cost of supplies: $8.00
  • Seller's fee: 9% of $40 = 0.09 × $40 = $3.60
  • Shipping costs: $2.00
  • Total cost = $8 + $3.60 + $2 = $13.60

Profit = Revenue - Cost = $40 - $13.60 = $26.40

To find the <em>hourly profit</em> you must divide the profit of a piece by the <em>hours of labor</em> to make a piece.

  • Hourly profit = $26.40/1.5hour = $17.60/hour
