3 times 6 is 18

2/4 is larger than 2/8, so we know our answer will be a fraction; part of a whole number.

We can simplify 2/8 into 1/4, as well as 2/4 into 1/2.

Now our question is simply how many times 1/2 goes into 1/4.

1/4 ÷ 1/2

We can go ahead and turn it into a multiplication problem using keep switch flip.

Keep  Switch  Flip

 1/4        x       2/1

1/4 x 2/1

And now cross simplify.

1/2 x 1/1

And solve

2/1 x 1/1 = 1/2

1/2 is a fraction, confirming our prediction.

- cancels so, 126/9=14

The answer is 19.

what is the inverse of -2 1/2

- 2 1/2 = -5/2

So, the inverse or the reciprocal is:

-2/5

(2/8) / (2/4)=2/8 x 4/2=8/16 =1/2

The value of the 3 is the billions place.

Never mind. I just figured it out. No need for anybody to waste time on trying to figure out my problem.

2/4 is half

2/8 is a quarter 

therefore there are 2, 2/8 in 1, 2/4

sqrt(8)  =  sqrt(4 · 2)  =  sqrt(4) · sqrt(2)  =  2·sqrt(2)

[ sqrt(8) + 6 ] / sqrt(2)  =  [ 2sqrt(2) + 6 ] / sqrt(2)  

Multiply both numerator and denominator by sqrt(2);

                                     =  [ 2sqrt(2) + 6 ] · sqrt(2) / [ sqrt(2) · sqrt(2) ]

                                     =  [ 2 · sqrt(2) · sqrt(2)  +  6 · sqrt(2) ]  / 2

                                     =  [ 2 · 2 + 6 · sqrt(2) ] / 2

                                     =  [ 4 + 6 · sqrt(2) ] / 2

                                     =  2 + 3sqrt(2) 

This is a composite number. Its prime factors are:

Did you think we couldn't crack it???

it equals 14

Your rate is 7/2 =3.5 pages per hour

Your classmate =8/3 =2 2/3 pages per hour

Your combined rate=3.5 + 2 2/3= 6 1/6 pages per hour

So 37 pages can be typed in: 37/(6 1/6) =6 hours.

It depends upon how far apart they are when they start.

Daily dose = 15*0.7 mg/day

!4 day dose = 15*0.7*14 mg

Number of 2mg tablets = 15*0.7*14/2 

You can crunch the numbers!

.

6²  =  36, a perfect square.

Actually, any number to the power of 2 is a perfect square.

If you can type 7 pages in 2 hours, then you can type

      7/2 pages per hour  =  3 1/2  pages/hour.

If your classmate can type 8 pages in 3 hours, then that person can type

      8/3 pages per hour  =  2 2/3 pages per hour.

The two of you, working independently on two computers, can type  

      (3 1/2) + (2 2/3) pages per hour  =  6 1/6 pages per hour.

37 pages / (6 1/6 pages per hour)  =  6 hours.

You would have typed  (3 1/2 pages/hour) x (6 hours)  =  21 pages.

Your classmate would have typed  (2 2/3 pages/hour) x (6 hours)  =  16 pages.

5.51*10^-6 → 0.00000551

Like so:

Can you work it out from the graph?

.

6 hours

The anwser is 15/6 because You will need to devide?

sqrt(8)  =  sqrt(4 · 2)  =  sqrt(4) · sqrt(2)  =  2·sqrt(2)

[ sqrt(8) + 6 ] / 2  =  [ 2sqrt(2) + 6 ] / 2  =  [ 2( sqrt(2) + 3 ) ] / 2  =  sqrt(2) + 3

Since they are consecutive numbers, then the average of the 3 is:

216/3 =72. So, the 3 numbers would be:

72-1 =71

72+1=73, so that:

71+72+73=216.

You can solve it by using n, n+1, n+2 as well.

If this means y*tan45 = y*tan60 then no, it's just false (unless y = 0).

However, if y is a function and tan45 and tan60 are arguments then it's possible that the statement is true, depending on the function.

For example, if \(y(x)=(1+\sqrt3-2x)^2\)  then \(y(\tan{45°})=y(1)=(\sqrt3-1)^2\)  and \(y(\tan{60°})=y(\sqrt3)=(1-\sqrt3)^2\)  so y(tan45°) = y(tan60°)
