Q.1A.). Tim has a scale model of an airplane which says it is in a 1:15 ratio what shoes that mean? Answer: It means that the scale model of the Airplane; Tim has is 15 times smaller than it's real size.
Q.2B.). If a scale factor is LESS than one, then the object will scale REDUCTION or WRITTEN as a FRACTION; bigger to smaller dimensions.
Q.3C.). If a scale factor is GREATER than one, then the object will scale A SKETCH; to larger dimensions.
Summary: A scale factor describes how much larger; or smaller; The enlarged shape is compared to the original shape.
• A description of a dilation includes the scale factor (or ratio) and the center of the dilation.
• The center of dilation is a fixed point in the plane.
• If the scale factor is greater than 1, the image is an enlargement (a stretch).
• If the scale factor is between 0 and 1, the image is a reduction (a shrink).
• If the scale factor is 1, the figure and the image are congruent.

The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
Given data:
The numbers of books read by Greta are 2.
The expression for the given statement is,
1 month = 2 books
Multiply the above expression by 16 onn both sides.
16(1 month)=16(2 books)
16 months= 32 books
Thus, 32 books read by Greta in 16 months.
The heights (in inches) of 13 plants are 6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16, and 17. What is the interquartile range o

The given heights:
6, 9, 10, 10, 10, 11, 11, 12, 12, 13, 14, 16, 17.
The first step is to find Median in order to divide the above series into lower and upper quartiles.
To find the median, just cross out the first and the last value until you left with the single value, as the number of elements is odd.
Like first 6 would cancel the last 17,
second number 9 would cancel the second last number 16,
and so on.
By doing above exercise, we are left with 11.
So the median = 11.
Now any number below the median 11 would be in lower quartile series, while other half would be in upper one.
To find the lower quartile, find the median of 6, 9, 10, 10, 10, 11:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:
The two elements are: 10, 10.
Take average = (10 + 10) / 2 = 10
So lower quartile = 10
To find the upper quartile, find the median of 12, 12, 13, 14, 16, 17:
Now the numbers are even; therefore, we would do the above-mentioned exercise of cancelling first and the last element until we are left with just 2 elements:
The two elements are: 13, 14.
Take average = (13 + 14) / 2 = 13.5
So Upper quartile = 13.5
The interquartile range = Upper Quartile - Lower Quartile = 13.5 - 10.0 = 3.5
So the correct option is (A) 3.5

Answer</h2>
Domain is (5, ∞), {x| x is greater than 5} for all integer n
Range is (-∞, ∞), {y| y belongs to Reals numbers}
<h2>
Explanation</h2>
Set up the equation for x
or,
x > 5
So the domain is all values of x greater than 5 to infinity.
Range is set of all correct or valid values of y.
Range = (-∞, ∞), {y| y belongs to Reals numbers}
