Hello from MrBillDoesMath!
Answer: 9/25
Discussion:
My first observation is that both 36 and 100 are even numbers, so let's divide each by 2.
36/100 = 18/50
Again, 18 and 50 are even numbers so let's divided each by 2
= 18/50 = 9/25
While I didn't write it out, my statement "divide them by 2" is really this:
36/100 = ( 36/2) / (100/2) = (18) /50 = ( 18/2) / (50/2) = 9/25
Confusing, isn't it!
A shorter, but equivalent, approach is to divide the numerator and denominator by 4.
Regards, MrB.
The number is 175
greater than 100 less than 200, 10-5=5, 5+2=7

c=sqrt(45)
Answer:x = 164686.592598
Step-by-step explanation:
219379.01−x/x = 0.3321
−x+219379.01/x = 0.3321
Step 1: Multiply both sides by x.
−x+219379.01≈0.3321x
−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)
−1.3321x + 219379.01 = 0
−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)
−1.3321x = −219379.01
−1.3321x/−1.3321 = −219379.01/−1.3321
(Divide both sides by -1.3321)
x = 164686.592598
The final answer is x=12
So the ladder will reach 12 feet up
