36 w x 48 hr = 1728 worker hours to complete the job
1728 w h /24 w = 72 hrs for only 24 workers
\(55\% \text{ off means you pay }(100\%-55\%) = 45\%\\ 45\% \text{ of }\$65 = (0.45)65 = \$29.25\)
EP i think you are assuming that this is a regular octagon which it may well not be.
Just in case you are unsure :
density = mass/volume
9 x 10 = 90 divisible by 15
99 x 100 = 9900 divisible by 4 and 15
999 x 1000 = 999 000 divisible by 4 and 15 see a pattern here?
B: 2400 cents /80 cents/magnet = 30 magnets 2400/120 = 20 magnets
4800 total / (30 + 20 magnets) = 96 cents/magnet
Instead of bashing, we can use the formula: \(\frac{n(n+1)}{2}\)\(\) , so \(\frac{9*10}{2}=9*5=\boxed{45}.\)
Nobody else can, though!
Sure, why not?
1+2+3+4+5+6+7+8+9 = 45!
\(d=\frac{m}{V}\), density=d, m=mass, and V=volume.
density=mass divided by volume
Hint: Try to set up an equation.
Solution: To start off, we have \(9x-26=5x+26.\) \(4x=52, x=13\) and plug it back at \(5x\) to get your answer.
Should be \(13*5=\boxed{65}.\)
I have always enjoyed mathematics recreationally.
Many people do.
It means an exponent follows
It means that a number has an exponet
for example - 2^2 = 22
^ is referring to an exponent! It means an exponent follows a number, for instance, 576^2 means 576 to the power of 2 or 576²
If you know my grammar is messed up, why don't you know what 1+1 is and 1*1 is?
