Answer:
You spent 40% of your budget on office supplies.
Step-by-step explanation:
1. First take the total budget:
$25
2. Then take the money you spent on office supplies and divide it by the total budget to find the ratio you spent:
3. Finally multiply the ratio by a hundred to find the percentage of the budget you spent on office supplies:
%
Therefore, you spent 40% of your budget on office supplies.
Answer:
Factor:
9x2 – 64
=(3x+8)(3x−8)
3x – 8
Answer:
To start off, this fraction needs to be rationalized; you can't have a radical in the denominator. So, you multiply both the numerator & denominator by the same number (so as to not mess up the proportion of numerator:denominator; it's like multiplying by 1) & get the radical out of the denominator. What number would that be? sqrt5.
So we have (sqrt6/sqrt5)•(sqrt5/sqrt5).
To simplify that, we get (sqrt6•sqrt5)/(sqrt5•sqrt5).
This can be rewritten as:
sqrt(6•5)/sqrt(5•5)
= sqrt30/sqrt25
Now, sqrt25 = 5, so that problem is solved as such:
sqrt30/5
I'm thinking sqrt30 can't be simplified any further. If it can, do so.
Hope this helps!
