A pool can be filled to 15,000 gallons of water. It takes 9 gallons per minute to fill the pool. How much minutes does it take to fill the pool?

Answers

Answer:

1666.7 minutes

Step-by-step explanation:

To find out how many minutes it takes to fill the pool, you can use the formula:

Time (minutes) = Total volume / Flow rate

In this case, the total volume of the pool is 15,000 gallons, and the flow rate is 9 gallons per minute.

Time (minutes) = 15,000 gallons / 9 gallons per minute

Time (minutes) = 1,666.67 minutes (rounded to two decimal places)

So, it takes approximately 1,666.67 minutes to fill the pool.

What property or properties were used to prove that the expressions are equivalent?
commutative and distributive properties
associative and distributive properties
associative and commutative properties
associative property

Answers

The proof used the distributive property and the associative property of multiplication.

Option B is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the liketerms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To be specific, the distributiveproperty was used to break down the expression 4t + t as:

4t + t = (4 + 1)t ________(1)

And then the associativeproperty was used to rearrange the terms as:

(4 + 1)t = 5t ________(2)

From (1) and (2)

We have shown that 4t + t is equivalent to 5t.

Thus,

The proof used the distributive property and the associative property of multiplication.

If x and y are negative integers and x – y = 1,
what is the least possible value for xy?

Answers

x=y+1
Least possible value for y(y+1)? Well, it appears for y halfway between the roots (you know what a parabola is, don't you?). That y is -0.5, so let's calculate -0.5*0.5, which is -0.25.
The least possible value is -\frac{1}4
Well, not really :)) The two values must be both negative, so we can't take one of them to be 0.5! As we lower the values, however, the product grows, reaching 0 when x=0 and y=-1, and further increasing as x and y lower. Thus, we would actually take x=0 and y=-1.

Bety compró 16 pares de calcetas, entre blancas y negras, y pagó $339. Los pares de calcetas blancas cuestan $24 y las negras $19. Plantea el sistema de ecuaciones y resuelve por el método que creas conveniente. Después toma foto y súbela en donde se indica.

Answers

Answer:

Sistema de ecuaciones:

x+y= 16

24x+19y=339

Respuesta:

x=7, y=9

Step-by-step explanation:

Con la información del enunciado puedes plantear las siguientes ecuaciones:

x= cantidad de calcetas blancas

y= cantidad de calcetas negras

x+y= 16 (1)

24x+19y=339 (2)

Para resolver las ecuaciones, debes iniciar despejando x en 1:

y=16-x (3)

Después, debes reemplazar (3) en (2) y despejar x para encontrar su valor:

24x+19(16-x)=339

24x+304-19x=339

5x=339-304

x=35/5

x=7

Luego, puedes reemplazar el valor de x en (3) para encontrar y:

y=16-x

y=16-7

y=9

De acuerdo a esto, x= 7, y=9.

A student made a model of a building. The model was 3 feet high and 12 feet wide. The building is 720 feet wide. Which proportion correctly show how to find the height of the building?

Answers

Ok, so what we do is simply divide 720 by 12
720/12=60 next you just multiply whatever part of the building by 60 in order to get a correct proportion in this case we are doing 60*3=180 and the answer is the height of the building must be 180 feet.
