It is scale factor at 1/14.
What does scale factor mean?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller). For instance, by increasing each side by, say, 2, we can expand the size of a rectangle with sides of 2 cm and 4 cm.
The fundamental equation to determine a figure's scale factor is written as, Scale factor is equal to the difference between the dimensions of the new and old shapes.

There are 3 computer games she can brought at $75.
Unitary method
Unitary method is defined as the process of finding the value of a unit and then the value of a required number of units.
Given,
Arianna buys computer games from an online store.
Each game she orders costs $22 and shipping for her total is $9.
Arianna can spend no more than $75.
Here we need to find how many computer games did Arianna Brought.
Let x be the number of computer games she brought.
We know that,
Cost for one game = $22
Shipping cost = $9.
She spent = $75.
So, it can be written as,
=> 22x + 9 = 75
=> 22x = 75 - 9
=> 22x = 66
=> x = 66/22
=> x = 3.
So, she can brought 3 computer games at $75.

What is the price of a perpetuity that has a coupon of $55 per year and a yield to maturity of 2.5%? the price of the perpetuity is $?
The price of the perpetuity is $2200
What is price of the perpetuity?The present value of a perpetuity is determined by simply dividing the amount of the regular cash flows by the discount rate. A growing perpetuity includes a growth rate that increases the cash flows received each period going forward.
Given:
coupon=$55
yield to maturity=2.5%
As, we know price of the perpetuity is determined by dividing the coupon by the yield to maturity.
So,
price=coupon/yield to maturity
price=$55/2.5%
price=$2200
Hence, the price of the perpetuity is $2200

An equilateral triangle is inscribed in a circle of radius 2r. express the area a within the circle but outside the triangle as a function of the length 3x of the side of the triangle.
The expression for the area within the circle but outside the triangle as a function of the length 3x of the side of the triangle is [tex]\frac{88r^2}{7}-\frac{9\sqrt{3} }{2}x^2[/tex].
It is given that:-
Radius of circle = 2r
Length of side of equilateral triangle = 3x
We have to find the expression for the area within the circle but outside the triangle as a function of the length 3x of the side of the triangle.
We know that,
Area of circle = [tex]\pi R^2[/tex]
Where R is the radius of the circle.
We have R = 2r
Area of an equilateral triangle = [tex]\frac{\sqrt{3} }{2}a^2[/tex]
Where, a is the length of side of equilateral triangle.
a = 3x
Hence,
Expression = [tex]\pi R^2-\frac{\sqrt{3} }{2}a^2[/tex]
Expression = [tex]\frac{22}{7}*(2r)^2-\frac{\sqrt{3} }{2}*(3x)^2 = \frac{88r^2}{7}-\frac{9\sqrt{3} }{2}x^2[/tex].

If a person with an hourly pay of $9.50 per hour gets a 20$ raise, what is the new hourly pay?
Percent formula, show your work
======================================================
Work Shown:
20% of $9.50 = 0.20*9.50 = 1.90
You earn an extra $1.90 on top of the $9.50 already there. So the new wage is 9.50 + 1.90 = 11.40 dollars per hour
-----------
Shortcut:
1.20*9.50 = 11.40
Think of 1.20 as 100% + 20% = 1 + 0.20 = 1.20, and this represents an increase of 20%
