I think you would do 897 divided by 50. Tell me if im wrong.

To find the number of steps between each landing in an 897-step stairwell with 50 landings, divide the total steps by the number of segments, resulting in approximately 17 to 18 steps per segment.

Step by Step Solution:

To determine how many steps are between each landing in an 897-step stairwell with 50 landings, follow these steps:

Therefore, each segment will have approximately 17 or 18 steps.

Answer:

-4( -2x^2 -3x+4)

Step-by-step explanation:

8x^2+ 12x-16​

Factor out a 4 from each term

4 (2x^2 +3x-4)

We can also factor out a negative 4

-4( -2x^2 -3x+4)

it is the first one -4(-2x^2-3x+4)

Answer:

20x² - 10x - 30

Step-by-step explanation:

Height = 5

Width = 4x² - 2x - 6

Area of rectangle = length × breadth

Area of triangle = height × width

Area = 5 × (4x² - 2x - 6)

Area = 20x² - 10x - 30

Area of the rectangle is 20x² - 10x - 30

The number of items carol can buy is 225.

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Given that Carol bought some items at a variety store. All the items were the same price, and she bought as many items as the price of each item in cents. The items cost 10 cents, she would have bought 10 of them.) Her bill was $2.25.

The number of the items will be calculated as below:-

1 dollar = 100 cents

2.25 dollars = 2.25 x 100 cents

2.25 dollars = 225 cents.

It is given that the number of items bought is equal to the number of cents.

Therefore, the number of items carol can buy is 225.

Let x represent the number of times Joe should expect the spinner to land on green.

We have been Joe has a spinner. The probability of landing on green is 3/8. Joe spins the spinner 184 times. We are asked to find the number of times Joe should expect the spinner to land on green.

We will use proportions to solve our given problem.

[tex]\frac{\text{Green}}{\text{Total}}=\frac{3}{8}[/tex]

Upon substituting our given values in above equation, we will get:

[tex]\frac{x}{184}=\frac{3}{8}[/tex]

[tex]\frac{x}{184}\cdot 184=\frac{3}{8}\cdot 184[/tex]

[tex]x=3\cdot 23[/tex]

[tex]x=69[/tex]

Therefore, Joe should expect the spinner to land on green 69 times.

Step-by-step explanation:

The solution is 2( 14 + w ) = 54. The width of the frame is 13 inches.

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Perimeter of the rectangle = 2(length+width)

Given the parameters are;

Rectangular picture frame has a perimeter of 54 inches. The height of the frame is 14 inches.

Perimeter of the rectangle = 2(length+width)

Perimeter = 2( 14 + w )

2( 14 + w ) = 54

Solving;

28 + 2w = 54

2w = 54 - 28

2w = 26

w = 13

The width of the frame is 13 inches.

To find the width of a rectangular picture frame when the perimeter is 54 inches and the height is 14 inches, we start by understanding the formula for perimeter of a rectangle, which is P = 2l + 2w, where P is the perimeter, l is the length (or height), and w is the width. In this case, we are given that the perimeter (P) is 54 inches and one dimension (the height/length, l) is 14 inches.

Substitute the known values into the perimeter formula to get 54 = 2(14) + 2w. Simplify the equation by first multiplying 2 by 14, which gives 54 = 28 + 2w. To isolate w, subtract 28 from both sides of the equation: 26 = 2w. Finally, divide both sides by 2 to find the width: w = 13 inches.

The solution is 54 = 2(14) + 2w = 28 + 2w. The width of the frame is 13 inches.

Over (-2, ∞) the graph of function y = | x + 2| is increasing.

Given that,
To determine over what interval the graph of y = |x + 2] increases.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
y = | x + 2|
Since from (∞, -2), the graph is decreasing, but at -2 the graph has zero ordinate and afterward, the graph starts increasing. So, over (-2, ∞) the graph of function y = | x + 2| is increasing.

Thus, over (-2, ∞) the graph of function y = | x + 2| is increasing.

Option D or 3

Step-by-step explanation:

It says so on edge 2020. I thought it was option c, but it is D. Can anyone tell me whyyyyyy.

The solution is, the scale factor of this dilation is option D. 3.

A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.

here, we have,

given that,

Line segments X Y and X prime Y prime.

From the point of dilation, the distance to point Y is 3 and the distance to point X is 2.

The distance from point Y to Y prime is 6, and the distance from X to X prime is 4.

Hence, The solution is, the scale factor of this dilation is option D. 3.
