The interior volume of a refrigerator is 25 cubic feet. The overall dimensions of the refrigerator are 50 inches by 35 inches by 69 inches. What is the approximate difference between the entire volume of the refrigerator and its interior volume?

Answers

Answer:

8725 cubic feet

Step-by-step explanation:

First, you have to figure out the volume of the refrigerator which your equation is:

length x width x height = volume

50 x 35 x 60 = 105,000 cubic inches

then you can transfer either inch to feet or feet to inch.

8750 cubic feet

to 25 cubic feet

So we have the equation 8750 - 25 = 8725 cubic feet

Answer:

The approximate difference between the entire volume of the refrigerator and its interior volume is 44.88 cubic feet

Step-by-step explanation:

What is volume?

Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.

Given,

Interior Volume = 25 cubic feet = 43200 cubic inches

The Entire volume of the refrigerator is,

=50*35*69

=120750 cubic inches

Approximate Difference

=120750 - 43200 = 77550 cubic inches = 44.88 cubic feet.

En una tienda de antigüedades una lámpara cuesta $1956 que precios representa el 25% y el 50% del precio total

Answers

Answer:

Resultados están más abajo.

Step-by-step explanation:

Dada la siguiente información:

Costo total= $1,956

Para calculate el valor parcial, debemos usar la siguiente información:

Precio proporcional= costo total* ( 1 - porcentaje de descuento)

50%:

Precio proporcional= 1,956*(1 - 0.5)

Precio proporcional= $978

25%:

Precio proporcional= 1,956*(1 - 0.75)

An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.

y = x + 15
y = −x + 8

Which of the following statements is a correct step to find x and y?

and could somebody please give me a step by step explanation

Answers

Since both equations equal y, you can combine them to x+15=-x+8
Next you need to move both variables to the same side so you can subtract x from both sides so it would be 15=-2x+8
Now you want to get the variable alone so you’d subtract the 8 from each side of the equation and you’d be left with 7=-2X
Lastly you one just one x so divide each side by -2 and you’d have 7/-2=x
x= -7/2 or -3.5

Let me know if you want further explanation of how I got x.

Answer:

x = −3.5

y = 11.5

Step-by-step explanation:

y = x + 15

y = −x + 8

[We know that y is 15 units more than x, and that −x is 8 units less than y. That can be combined into −x + 8 = x + 15 for the first variable (x), and for the second variable (y), y − 15 = −y + 8]

↓

In order to solve this, solve for the first variable in one of the equations, then substitute the result into the other equation.

↓

x = −[tex]\frac{7}{2}[/tex] = −3.5

y = [tex]\frac{23}{2}[/tex] = 11.5

Originally, a department store bought a set of dishes at a cost of $57.68 and marked it up 125%. After a month, the set of dishes had not sold, so the store marked it down 50%. What was the discounted price?

Answers

Answer:

$64.89

Step-by-step explanation:

57.68 + 1.25 × 57.68

= 57.68 + 72.1

= 129.78

The original price was $129.78.

129.78 – 0.50 × 129.78

= 129.78 – 64.89

= 64.89

The discount price was $64.89.
