En la casa de la familia de Trevor viven 6 personas (incluyendo a Trevor) y hay 3 baños. En el último mes, cada
persona se bañó durante un promedio de 480 minutos y utilizó un promedio de 72 litros de agua al bañarse
(en todo el mes). El agua cuesta 0.20 dólares por litro.
¿Cuánto dinero gastó la familia de Trevor en total en agua al bañarse el mes pasado?
dólares.

Answers

Answer 1

Answer:

La familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

                                                       

Step-by-step explanation:

El costo del agua viene dado por:

[tex] C = \$0.20/L [/tex]   (1)

Y cada persona de la familia de Trevor gasto en promedio 72 litros de agua. Si la familia tiene 6 integrantes (incluido Trevor) entonces:

[tex] A = 72 L*6 = 432 L [/tex]    (2)

Entonces, toda la familia usó 432 litros de agua en promedio en todo el mes.

Para saber el dinero total gastado por la familia debemos multiplicar la ecuación (1) y la ecuacion (2):

[tex] C = \$0.20/L*432 L = \$86.4 [/tex]

Por lo tanto, la familia de Trevor gastó 86.4 dólares al bañarse en todo el mes.

Espero que te sea de utilidad!                                    

Answer 2

Usando proporciones, hay que la familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.

En la casa, hay 6 personas.Cada persona utilizó un promedio de 72 litros de agua.

Por eso, en todo, 6 x 72 = 432 litros de agua fueron usados.

Cada litro cuesta $0.2. De esa forma, el total de dinero gasto es de:

T = 0.2 x 432 = 86.4.

La familia de Trevor gastó 86.4 dólares en total en agua al bañarse el mes pasado.

Jackson's rectangular bedroom has an area of 80 square feet. The area of his bedroom is 10 times that of his rectangular closet. If the closet is 2 feet wide, what is its length? BE SURE TO ADD A LABEL TO YOUR ANSWER.

Answers

Answer:

Length of the rectangular closet = 4 feet

Step-by-step explanation:

Area of his bedroom = 80 square feet.

The area of his bedroom = 10 times that of his rectangular closet.

Let x = area of his rectangular closet.

80 = 10 * x

80 = 10x

x = 80/10

= 8

x = 8 square feet

If the closet is 2 feet wide, what is its length?

Area of the rectangular closet = length × width

Let y = Length of the rectangular closet

8 Square feet = y feet × 2 feet

8 = 2y

y = 8/2

= 4

y = 4 feet

Length of the rectangular closet = 4 feet

Shortbread Cookies Makes about 3 dozen cookies 3/4 shortening 1/2 t salt 9/4 granulated sugar I 1/2 t baking soda 1/4 eggs 2 c. cake flour 1/2 vanilla extract food coloring 1/4 butter flavoring

Answers

Answer:

3/8 shortening, 1/4 t salt, 9/8 sugar, 3/4 baking soda, 1/8 eggs, 1 c. Cake flour, 1/4, vanilla extract, 1/8 butter flavoring

Step-by-step explanation:

Half all your fractions, by doubling the numerator and denominator, then deviding the numerator by 2.

The amount require for 1 and half dozens is

3/8 shortening 1/4 t salt 9/8granulated sugar 3/4t baking soda 1/8 eggs 1 c. cake flour 1/4 vanilla extract food coloring 1/8 butter flavoring

What is Unitary Method?

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Let's first list the data that we currently have. The number of ice creams is 5. It costs $125 for 5 ice creams.

Step1 :Let's start with finding the price of one ice cream. Divide the entire cost of ice cream by the total number of ice creams to get at that. A single ice cream will cost you 125 divided by the amount of ice creams, or 25 cents. Consequently, 1 ice cream costs $25.

Step 2: To calculate the price of three ice creams, multiply the price of one ice cream by the quantity. Cost of 1 ice cream x number of ice creams = 25 x 3 = $75 is the price of 3 ice creams. The final cost is $75, which is the price of three ice creams.

Given:

Shortbread Cookies Makes =3 dozen cookies

3/4 shortening

1/2 t salt

9/4 granulated sugar

3/2 t baking soda

1/4 eggs

2 c. cake flour

1/2 vanilla extract food coloring

1/4 butter flavoring

Above we have ingredients according to 3 dozen but we want to have ingredients for 1 and half dozen which is half of 3 dozen

So, we will just make half of the amount of above ingredients present

Shortbread Cookies Makes =1 and 1/2 dozen cookies

3/4 x 1/2 = 3/8 shortening

1/2 x 1/2 = 1/4 t salt

9/4 x 1/2 = 9/8granulated sugar

3/2 x 1/2 = 3/4t baking soda

1/4 x 1/2 = 1/8 eggs

2 x 1/2 =1 c. cake flour

1/2 x 1/2 = 1/4 vanilla extract food coloring

1/4 x 1/2 = 1/8 butter flavoring

We know that for example 2/4=4/8 so it is multiplied by 2. In this problem the fractions are 2 2/4 and 6 1/8. We are subtracting so you would first multiply the fraction that’s going to subtracted from the other fraction 2 3/4= 2 6/8. Now that we have our fractions we can subtract 6 1/8-2 6/8 this would leave us with 3.375 which is equal to 3 3/8.

P.S. this is a Percent increase/decrease
from: 600
to: 1400

%/100 = differences of to and from/ from ( before the number )
( no negative difference, bigger number subtract smaller number)

Answers

Answer:

133.33333333 percent

the diffrence is 800

Step-by-step explanation:

[(1400 - 600) / 600] × 100%

= 1.3333333333 × 100%

= 133.33333333%

Answer:

133.33% increase

Step-by-step explanation:

This is a percent increase, and to solve for one you need to know the following formula

[tex]|\frac{new~value~-~original~value}{original~value}| *100[/tex]

Plugging it in;

New value = 1400

Old value = 600

[tex]|\frac{new~value~-~original~value}{original~value}|= |\frac{1400-600}{600}| = |\frac{800}{600}| = 1.333333333[/tex]

1.3333333 as a percent is

133.33%

So you have an increase of 133.33%

Write the slope-intercept form of the equation of the line through the point (-1,-5) with a slope of 5/6.

Answers

Answer:

5/6x+4 1/6=y

Step-by-step explanation:

The equation to find a slope-intercept is mx+b=y

m=slope

x=x coordinates

y=y coordinates

b= y intercept

m=5/6

x=-1

y=-5

b=4 1/6

Y intercept:

5/6(-1)+b=-5

-5/6+b=-5

b=4 1/6

However, it asks for an equation of the line, not (-1,-5), so we only need to write m and b, but not x and y.

So: 5/6x+4 1/6=y
