I'd suggest you write "6 2/5," not "6 and 2/5."
6 2/5 rotations
-------------------- =
2 2/3 seconds
32
---
5 32 3
------- = ------ * -----
8 5 8 Reduce that 32/8: obtain 4.
---
3
Then we have
4(3)/5, or 12/5 rotations per sec.
Sqrt(1-3x)=x+3
[sqrt(1-3x)]^2=(x+3)^2
1-3x=(x+3)(x+3)
1-3x=x^2+6x+9
-3x=x^2+6x+8
0=x^2+9x+8
The answers are -1 and -8 BUT, we have to plug them back into the original equation to make sure we don't get a negative under the square root sign.
After doing this, we realize that only -1 works, so the answer is x=-1
Sorry that this took forever to answer. I was thinking of a good way to explain this, and if you need any further explanation, message me:)
Best wishes:)
14.5% = 0.145 = 145/1000
14.5 = 14500/1000
<span>So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.</span>
