Answer:

To find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width. Find the area of each face that you see and then multiply each area by two to account for the face on the opposite side.

Answer:

The function rule be 100 × x

The independent variables i.e. (2, 3, and 4) are considered to be the domain

The dependent variable (200,300,400) are considered to be the range

Step-by-step explanation:

The computation is shown below:

As we know that

1 m = 100 cm

So

2 m = 200 cm

3 m = 300 cm

4 m = 400 cm

The function rule be 100 × x

The independent variables i.e. (2, 3, and 4) are considered to be the domain

The dependent variable (200,300,400) are considered to be the range

PLZ HELP 20 POINTS<br><br> Twenty-five percent of the data falls below the number
natta225 [31]
With finding the data that falls below a percentage, you need to look closely at the words. 

Notice that it said  25% of... that word "of" means to multiply. But, what are you multiplying? Well, if you look more closely at the plot, you'll see that your dot and line is lying on 58. But make sure you put 25 over 100.
 
So, your equation would be set up like this: 58 ÷ x = 100/25
We're using "x" as our way of saying, "We need to find out this number." 

After that, we'll need to multiply both sides of the equation by "x"
 
(58 ÷ x) × x = (100/25) × x

Now that you have your equation, you'll need to divide both sides by 4 to get "x". 

x = 4 ÷ 58

58 ÷ 4 = 14.5

Your answer is 14.5 of the data that falls below the number.

As we can see in the line plot below, we have:

  • 3 * 1/2 = 1.5
  • 5 * 1 = 5
  • 6 * 1 1/2 = 9

Now, adding up we have:
