Answer:

<u>2 Meters deep.</u>

Step-by-step explanation:

If you multiply 36.8 m by 20m, you would get the base area of 736 m^2. If you divide that by 1472, you would get 2 meters deep.

To find the depth (aka "height") you must use the volume formula

Volume = length x width x height

In this case:

The amount of water the pool can contain will equal to the volume

Volume = 1,472 m

length = 36.8 m

width = 20 m

height = unknown (let's make this h)

^^^Plug these numbers into the formula given above

1,472 = 36.8 x 20 x h

1,472 = 736h

Isolate h by dividing 736 to both sides

1,472/736 = 736h/736

This pool is 2 meters deep

Hope this helped!

nadezda [96]

Answer:the cost of renting one movie is $1.5

the cost of renting one video game is $5.2

Step-by-step explanation:

Let x represent the cost of renting one movie.

Let y represent the cost of renting one video game. One month melissa rented 12 movies and 2 video games for a total of $29. This means that

12x + 2y = 29 - - - - - - -1

The next month she rented 3 movies and 5 video games for a total of 32$. This means that

3x + 5y = 32 - - - - - - - - 2

Multiplying equation 1 by 5 and equation 2 by 2, it becomes

60x + 10y = 145

6x + 10y = 64

Subtracting,

54x = 81

x = 81/54 = 1.5

Substituting x = 1.5 into equation 2, it becomes

3x + 5y = 32

3×2 + 5y = 32

5y = 32 - 6 = 26

y = 26/5 = 5.2

Which pair represents the same complex number?

lorasvet [3.4K]

For this case we have the following complex number:
1 + i
Its equivalent pair is given by:
root (2) * (cos (pi / 4) + i * sin (pi / 4))
Rewriting we have:
root (2) * (root (2) / 2 + i * (root (2) / 2))
(2/2 + i * (2/2))
(1 + i)
Answer:
option A represents a pair with the same complex number

<h2>Answers:</h2>

Question 1: The equations share the same slope, but different y-intercepts.

Question 2: Option B (y = 2x + 1)

<h2>Explanations:</h2><h3>For Question 1:</h3>

Both equations are written in slope intercept form.

$y = mx+b\\\\\text{m - slope}\\\text{b - y-intercept}$

The equations we have are:

$\left \{ {{y=2x} \atop {y=2x-7}} \right.$

Both equations share the same slope of 2. However, they have different y-intercepts.

y = 2x can be written as y = 2x + 0.

Usually if you only have the slope in your equation then the y-intercept is the origin, or (0, 0).

The second equation's y-intercept is -7. It takes 'b's place.

<h3>For Question 2: </h3>

We are given a graph and we need to find a equation.

According to the graph, the line passes at (0, 1). 1 is the y - intercept.

Since y = 2x + 1 is the only option with 1 as the y - intercept, it should be the correct answer.

I'll do the slope as well to verify our answer.

I will use the points (-1, -1) and (1, 3).

$m=\frac{3-(-1)}{1-(-1)}=\frac{4}{2} =\boxed{2}$

The correct answer should be $y = 2x+1$ .

Hope this helps you.
