Addition can be defined as the process of adding two numbers such that the result is the combined value of the two numbers.

To make a profit the Better builder company needs to add all the expenses and the profit they need to make. Therefore, the sum can be written as,

Total Bil = $672.25 + $86.77 + $39.41 + $180.96 + $204.35 + $225

              = $1408.74

HURRY PLEASE When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6? The ratios are equivalent to 5:6. The ratios are equivalent to 6:5. The ratios are greater than 5:6, as the factors become greater. The ratios are greater than 6:5, as the factors become greater.

Answers

Answer:

The ratios are equivalent.

Step-by-step explanation:

If you multiply both 5 and 6, the ratio stays the same.

5:6 = 10:12 = 15:18 = 20:24 etc.

You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.

24/20 = 1.2

15/18 = 1.2

10/12 = 1.2

6/5 = 1.2

9:25 y 33:41:38 a que unidades de tiempo se refieren?

Answers

Answer:

Se refieren a las unidades de tiempo del sistema sexagesimal

9:25 son 9 minutos y 25 segundos

33:41:38 son 33 horas, 41 minutos y 38 segundos.

Step-by-step explanation:

El sistema sexagesimal se utiliza para medir tiempos y ángulos.

El tiempo se mide en horas,minutos y segundos

En cambio, los ángulos se miden en grados,minutos y segundos.

Los dos puntos '':'' sirven para separar las unidades.

La base de este sistema es el número 60 :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 hora

Eso en cuanto a tiempo

En cuanto a grados :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 grado

Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos

Entonces, 9:25 son 9 minutos y 25 segundos

Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).

Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

7x-(6x-1)=2. What is the answer?

Answers

Answer:

x=1

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x−(6x−1)=2

7x+−1(6x−1)=2(Distribute the Negative Sign)

7x+−1(6x)+(−1)(−1)=2

7x+−6x+1=2

(7x+−6x)+(1)=2(Combine Like Terms)

x+1=2

x+1=2

Step 2: Subtract 1 from both sides.

x+1−1=2−1

A music company sells CDs for a particular artist. The company has advertising cost of $4,000 and recoding costs of $10,000; Their cost for manufacturing, royalties, and distribution are $5.50 per CD. They sell the CDs to Mage-Mart for $7.20 each

Answers

Answer:

Instructions are below.

Step-by-step explanation:

Giving the following information:

Fixed costs= 4,000 + 10,000= $14,000

Unitary variable cost= $5.5

Selling price= $7.2

To calculate the number of units to be sold to break-even, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 14,000 / (7.2 - 5.5)

Break-even point in units= 8,235 units

In dollars:

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 14,000 / (1.7/7.2)

Break-even point (dollars)= $59,294

Now, imagine the company requires a profit of $50,000:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point in units= 64,000/1.7

Break-even point in units= 37,647 units

Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio

Break-even point (dollars)= 64,000 / (1.7/7.2)

Break-even point (dollars)= $271,059

2(n+2)=4n+1-2n

Whats the answer

Answers

Answer:

no solution

Step-by-step explanation:

Given

2(n + 2) = 4n + 1 - 2n ← distribute parenthesis on left side

2n + 4 = 2n + 1 ( subtract 4 from both sides )

2n = 2n - 3 ( subtract 2n from both sides )

0 = - 3 ← not possible

This indicates the equation has no solution

The original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.

To solve the equation 2(n + 2) = 4n + 1 - 2n, we can simplify and then solve for the variable n.

First, distribute 2 to the terms inside the parentheses:

2n + 4 = 4n + 1 - 2n

Next, combine like terms on the right side:

2n + 4 = 2n + 1

Now, subtract 2n from both sides to isolate the n term:

2n - 2n + 4 = 2n - 2n + 1

4 = 1

Since 4 is not equal to 1, there is no solution to this equation.

Therefore, the original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.
