Answer:

17 inches

Step-by-step explanation:

Given

P = 51 --- Perimeter of rectangle

Required

The length of the original square

The perimeter is calculated as

51 = 2(L + W)

Divide by 2

25.5 = L + W

The rectangle and the square have the same length.

So:

L = 2W

25.5 = L + W becomes

25.5 = 2W + W

25.5 = 3W

Divide both sides by 3

W = 8.5

Recall that:

L = 2W

L = 2 * 8.5

L = 17

Pls help question b
Snowcat [4.5K]

Answer: 44

Step-by-step explanation:

1/5 of the slab are grey implies that 4/5 are yellow.

The ratio of grey to yellow is thus given as :

1/5 : 4/5

which is 1 : 4

Therefore , the ratio of grey to yellow is 1: 4

The total ratio = 1 + 4 = 5

To calculate the number of yellow , we use the formula

number of yellow = \frac{ratio of yellow}{total ratio} X  total number of slabs , that is

number of yellow = \frac{4}{5} X 55

number of yellow slab = 44

A function f(x) is graphed on the coordinate plane.
Sidana [21]

Answer: y = - 4x + 2


Explanation:


The graph shows a linear function, which is a first degree polynomial, whose form is ax + b.


The rule or fucntion is f(x) = y = ax + b. This form is called the slope-intercept form, because the coefficient a is the slope of the line and b is the y-intercept.


The graph permits you to calculate both parameters.


1) The slope, a is defined in this way:

  • a = rise / run = [change in y] / [change in x] = [y₂ -y₁] / [x₂ - x₁]
  • you can use the points (0, - 2) and (-1,2):

       ⇒ a = [ 2 - (-2) ] / [ -1 - 0 ] = 4 / (-1) = - 4

2) b, the y-intercept, is the value of the function, y, when x = 0. In the graph you can see that this is - 2. b =  - 2.


3) Substituting the values of a and b in the form y = ax + b, you the rule:

  • y = - 4x - 2

See attachment for the number line that compares the numbers 5.3, 5 1/5 and 5

<h3>How to plot the numbers on the number line?</h3>

The numbers are given as:

5.3, 5 1/5 and 5

We start by representing the numbers as decimals (i.e. real numbers).

So, we have:

5.3, 5.2 and 5

Reorder the numbers in ascending number (i.e. from least to greatest)

So, we have

5, 5.2 and 5.3

Next, we plot the numbers on a number line using a scale of 0.1

This can be visualized as

5        5.2      5.3

See attachment for the number line that compares the numbers 5.3, 5 1/5 and 5
