Decimal to percentage

Answers

To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right. This is done in the example below. Each decimal in Example 1 went out two places to the right of the decimal point.

The decimal you take it as it was of a hundred if it is just of 2 numbers

0.36= 36%

If it is of 3 numbers or more you can use decimals

0.873= 87.3%

What is the steepest line possible and what is its slope?

Answers

A slope is a descending line where the X and Y axis are indirectly proportion .For eg(if slope is coming down Y axis gets bigger and X axis gets smaller.

The steepest line possible is the ending point of the graph or any given value(Note this rule may not be logical on algebric graphs)

A 5-foot ladder is leaning against a 4-foot wall. How far must the bottom of the ladder be from the base of the wall so that the top of the ladder rests on the top of the wall.

Answers

This is a classic example of a right angled triangle where the ladder is the hypotenuse and the wall and the base of the wall are the other 2 sides of the triangle.
  
Since it is a right angled triangle, Pythagorean theorem will be applied to it. 

So, we use the formula - 
hypotenuse^2 = side1^2 + side2^2

Here, h
ypotenuse (ladder) = 5 feet, side1 (wall) = 4 feet, side2 (base of the wall) = unknown.

So, we have, 5^2 = 4 ^2 + side2^2
==> side2^2 = 5^2 - 4^2 
==> side2^2 = 25 - 16
==> side2^2 = 9
==> side2 = square root (9)
==> side2 = 3

So, the final answer is --> the bottom of the ladder is 3 foot away from the base of the wall.
A right angled triangle is formed here.
By Pythagoras theorem,
H² = B² + L²
where L is the altitude (wall), B is the base (ground) and H is the hypotenuse (ladder).
⇒ 5² = B² + 4²
⇒ 25 = B² + 16
⇒ B² = 25 - 16 = 9
⇒ B = 3
The bottom of the ladder must be 3 feet away from the base of the wall.
