Suppose an amount increases by 100%, then decreases by 100%. Find the final amount. Would the situation change if the original i

Anarel [89]

Well to solve this, lets plug in some numbers. Lets assume that for now, the starting number is 2. If it increases by 100%, bringing it up to 4, then decreases 100%, it is brought down to zero. Now one thing to note is that any number decrease by 100% is automatically zero. Watch, we start with two, it is then increased by 150%, bringing it up to 5, then decreased by 100%, bringing it back down to zero. In conclusion, 100% cannot be specified as a value, but rather a relation. 100% represents the entire number, meaning that if you are decreasing a number by 100%, you are basically subtracting the number by itself!

Jackson finds a cat stuck in a 20ft tree. Luckily he has a 25foot ladder. If the ladder leans against the tree leaving 6ft of sp

Hello!

This makes a triangle

The cat is 20 ft high

The triangle is 20 feet high

The is 6 ft between the ladder and the tree

The base is 6 ft long

You use the Pythagorean theorem to solve this

$a^{2} + b^{2} =c^{2}$

a and b are the base and height

put in the values you know

$6^{2} + 20^{2} = c^{2}$

square the numbers

36 + 400 = $c^{2}$

Add

436 = $c^{2}$

Take the square root of 436

20.9 = c

Since this is lower than the length of the ladder the ladder is long enough

The answer is yes

Hope this helps!
