The skyscraper will have 78 floors when it is finished.
A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
Let's assume that the total number of floors in the skyscraper is "x".
According to the problem, the builder has built 1/6 of the floors.
So the number of floors built by the builder is:
= (1/6)x
The problem also tells us that the builder has built 13 floors.
So we can set up the equation:
(1/6) x = 13
To solve for "x", we can multiply both sides by 6:
x = 78
Therefore,
The skyscraper will have 78 floors when it is finished.

Answer: About 80 yards
Step-by-step explanation:
Answer: 85
Step-by-step explanation:
Writing an Equation
Find the length of each side and add them up to get the total perimeter.
We know that there are 6 sides, AB, BC, CD, DE, EF, and FA
We also know that AB = ED and BC = CD = EF = FA
So the total perimeter would be AB + BC + CD + DE + EF + FA = 2AB + 4BC
Finding length of AB
This line goes from (-2,2) to (2,2) so we can find the length by subtracting the x coordinates since the y coordinates are the same
AB = 2 - (-2) = 4
Finding length of BC
Using the Pythagorean Theorem, we can find the length of BC
This line goes from (2,2) to (3,0)
The vertical distance (a) is |0-2| = 2
The horizontal distance (b) is |3-2| = 1
So
Total length
Using the equation 2AB + 4BC to find the perimeter we get
=
=
=
Since is approximately 9, we'll substitute in 9 (assuming we don't have a calculator)
≃ 8 + 9
= 17 units
Converting units
Each unit is 5 yards, so use this ratio get the perimeter in yards
17 units * 5 = 85 yards
