A painter built a ladder using 18 rungs. The rungs on the ladder were 5.7 inches apart and 1.1 inches thick. What is the distance from the bottom of the lowest rung to the top of the highest rung?
Answers
The distance from the bottom of the lowest rung to the top of the highest rung 116.7 inch
What is Unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Total rungs = 18
distance between rungs = 5.7 inch
thickness = 1.1 inches
So, the distance from the the lowest rung to top of highest rung is
=18* 5.7 + 17* 1.1
=116.7 inch

Let us also assume the cost of 1 pear = y dollars
Then we can form two equations from the details given in the question. Based on those details the required answer to the question can be easily deduced.
3x + 8y = 14.50
And
6x + 4y = 14
Dividing both sides of the equation by 2 we get
3x + 2y = 7
2y = 7 - 3x
y = (7 - 3x)/2
Putting the value of y from the second equation in the first equation we get
3x + 8y = 14.50
3x + 8[(7 - 3x)/2] = 14.50
3x + 4 (7 - 3x) = 14.50
3x + 28 - 12x = 14.50
- 9x = 14.50 - 28
- 9x = - 13.5
9x = 13.5
x = 13.5/9
= 1.5
Putting the value of x in the second equation we get
6x + 4y = 14
(6 * 1.5) + 4y = 14
9 + 4y = 14
4y = 14 - 9
4y = 5
y = 5/4
= 1.25
So we can find from the above deduction that the cost of 1 apple is 1.5 dollars and the cost of 1 pear is 1.25 dollars
Then
Cost of 2 apples = 2 * 1.5 dollars
= 3.0 dollars
So the cost of 2 apples is $3 and the cost of 1 pear is $1.25.

Answer:
36 1/8 feet
Step-by-step explanation:
x = height of house in feet
2"/8.5' = 8/5"/x

The total of T-shirts is proportional to the total of players, which means 15 players = 15 t-shirts.
What is a proportion?
A proportion describes the number of elements from one category compared to the number of elements in another. For example, if there are 15 boys and 15 girls in a classroom the number of girls and boys is proportional.
How are the number of t-shirts and players related?
These have a proportional relationship because for every player it is expected there is a determined t-shirts number and this number can only increase if the players increase.
1 t-shirt per player:
36 players = 36 t-shirts
2 t-shirts per player:
36 players = 72 t-shirts
