You put the decimal over a number with one more digget. if the number was .66 you would make it 66/100 if the number was .777 you would make the fraction 777/1000
Bill paints 1/2 per hour. Bob paints 1/3 per hour. 1/2x+1/3x=1
The multiplier each year is 1.02, so the multiplier for 7 years is 1.02^7.
220,000*1.02^7 ≈ 252,700
_____
4 significant figures is usually good enough for most real-world problems. (Unless you're counting pennies on your billion-dollar investment.)
It is 100 because 10 times 10 = 100.
Area= Length times Width
Answer:
- 20 -5k = 4
- the LCM of the denominators is 10
Step-by-step explanation:
I find it convenient to do the problem in the reverse order: find the LCM, then distribute. That way, I'm not distributing a fraction.
The LCM of 2 and 5 is their product: 2·5 = 10. Multiplying the equation by 10 gives ...
5(4 -k) = 4
Now, distributing, we get ...
20 -5k = 4
