A mermaid has a terrarium that measures 42 inches × 10 inches × 9 inches. She also has a box that measures 3 inches × 3 inches × 3 inches. Every minute, the mermaid fills the box with sand from her backyard and then pours the sand into the terrarium. How many minutes does it take the mermaid to fill three-quarters of the terrarium with sand?

Answers

9514 1404 393

Answer:

  105 minutes

Step-by-step explanation:

The volume of the terrarium is ...

  V = LWH

  V = (42 in)(10 in)(9 in) = 3780 in³

The volume of a box is ...

  V = (3 in)(3 in)(3 in) = 27 in³

Then the number of boxes it takes to fill the terrarium is ...

  (3780 in³)/(27 in³/box) = 140 boxes

The mermaid wants to fill it 3/4 full, so only needs 3/4 this number of boxes. That is 105 boxes. At the rate of 1 per minute, ...

  it will take 105 minutes to fill 3/4 of the terrarium

Which of the following ordered pairs, when graphed on a standard
coordinate plane, is located in quadrant I?

Answers

Answer:[tex]\boxed{\boxed{\sf{(-2\frac{1}{3},\frac{1}{3})}}}[/tex]Solution Steps:

______________________________

1.) First you need to graph all the ordered pairs:

(I have included the graph below)

2.) Then you determine which pairs are in the top left quadrant:[tex]=(-2\frac{1}{3},\frac{1}{3})[/tex]

So your answer is only [tex]\bold{(-2\frac{1}{3},\frac{1}{3})}[/tex].

x=10 and y=10 is it intercepting parallel or same line?

Answers

Answer:

Parallel lines have the same slope. Because the functions \displaystyle f\left(x\right)=2x+3f(x)=2x+3 and \displaystyle j\left(x\right)=2x - 6j(x)=2x−6 each have a slope of 2, they represent parallel lines. Perpendicular lines have negative reciprocal slopes. Because −2 and \displaystyle \frac{1}{2}

are negative reciprocals, the equations, \displaystyle g\left(x\right)=\frac{1}{2}x - 4g(x)=

2

1

x−4 and \displaystyle h\left(x\right)=-2x+2h(x)=−2x+2 represent perpendicular lines.

Answer:

Intercepting.

Step-by-step explanation:

The line x=10 is a straight vertical line going through all the points where x=10, as the equation suggests.

The line y=10 is a horizontal line going through all the points where y=10.

When you graph them, they intersect in a perfect cross.

A system of linear equations is shown below. 3x+5y=9 2x+3y=5 which ordered pair shows the solution to the system

Answers

Answer:

(-2,3)

Step-by-step explanation:

Given data

the system of linear equation is presented as

3x+5y=9-----1

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

solve simultaneously

3x+5y=9-----1  X 2

2x+3y=5-----2  X3

subtracting 2 from 1

 6x+10y=18

-6x+9y=15

0x+y=3

y= 3

put y= 3 in 1

3x+5(3)=9-----1

3x+15=9

3x= 9-15

3x= -6

x= -6/3

x= -2

Hence the ordered pair is (-2,3)

Answers

Answer:

[tex] \large \boxed{f(8) = 27}[/tex]

Step-by-step explanation:

Goal

Find f(8)

Given

Equation

[tex]f(x) = \frac{1}{2} {x}^{2} - ( \frac{1}{4} x + 3)[/tex]

Step 1

Substitute x = 8 in the equation and replace f(x) with f(8).

[tex]f(8) = \frac{1}{2} {(8)}^{2} - ( \frac{1}{4} (8) + 3)[/tex]

Step 2

Evaluate the value of f(8).

[tex]f(8) = \frac{1}{2} (64) - ( \frac{8}{4} + 3) \\ f(8) = 32 - ( \frac{2}{1} + 3) \\ f(8) = 32 - (2 + 3) \\ f(8) = 32 - (5) \longrightarrow 32 - 5 \\ f(8) = 27[/tex]

Hence, the value of f(8) is 27.

How do I graph y=2/3x-4

Answers

Step-by-step explanation:

In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.

The length of the subway is 900 miles.If 1 inch represents 45 miles ,what is the length of the subway on the map

Answers

Answer:

Step-by-step explanation:

The length of the subway is 900 miles.

So if 1 inch is 45....we want to find it for 900 miles

900/45 = 20

So it will be 20 inches for 900 miles

Check by using ratio

1 : 45

2 : 90

3 : 135

4 : 180

5 : 225

6 : 270

7 : 315

8 : 360

9 : 405

10 : 450

11 : 495

12 : 540

13 : 585

14 : 630

15 : 675

16 : 720

17 : 765

18 : 810

19 : 855

20 : 900

1 - 20 = inches

45 - 900 = miles

So for 900 miles, it will be 20 inches long
