Answer 2

Answer: You can turn these numbers into improper fractions. 5 1/3 can be changed to 16/3. 3 5/6 can be changed to 23/6. So now your equation is 16/3 - 23/6= ?
To do this we have to have common denominators. Since 3 times 2 can make 6, which is the other denominator then we can multiply the top which is 16 by 2 as well. This is because whatever you do to the top you have to do to the top. 16 times 2 is 32. Now we have 32/6-23/6. The denominator is going to stay the same so you don't have to worry about it. Take the numerators and subtract them.
32-23=?
You should have gotten 9.
So now you have 9 over 6. You can simplify this with a common factor which in this case is 3. 9 divided by 3 is 3. 6 divided by 3 is 2. You now have 3/2. You can simplify this back into a mixed number and that would give 1 1/2. This is because 2, the denominator, goes into 3 once with a remainder of 1. 1 over 2 is 1/2.
Your answer is 1 1/2.

What is (3x10) + (6x1) + (9x1/10) + (4x1/100) in standard form

Answers

30+6+0.9+0.04= 36.94

Standard Form just means in numbers e.g. 501.60

Writing this in huge spacing makes it easier for us:
3 * 10 + 6 * 1 + (9 * 1)/10 + (4 * 1) /100
30 + 6 + 0.9 + 0.04
= 36.94

What is the lim of (((1/x)-(1/2))/x-2) , as x approaches 2

I assume the denominator is $x-2$ .

$\lim_(x\to2)((1)/(x)-(1)/(2))/(x-2)=\n\lim_(x\to2)((2)/(2x)-(x)/(2x))/(x-2)=\n\lim_(x\to2)((2-x)/(2x))/(x-2)=\n\lim_(x\to2)(2-x)/(2x(x-2))}=\n\lim_(x\to2)-(x-2)/(2x(x-2))}=\n\lim_(x\to2)-(1)/(2x)}=\n-(1)/(2\cdot2)=\n-(1)/(4)=$

A computer is programmed to scan the digits of the counting numbers. For example, if it scans 1 2 3 4 5 6 7 8 9 10 11 12 13 then it has scanned 17 digits altogether. If the computer begins its task and scans the first 1392 digits starting at 1, what is the last counting number scanned?

Answers

I believed it is "401"

1-9 = 9 digits

10-99 = 90 which is 180

100-200 = 100 which is 300 digits

9+180= 189

1392-189= 1203

1200÷300=400 which 1200 digits

401 is the 1392 number scanned
