After working with fractions for a while, you may be able to 'feel' which is larger, but to be SURE, convert each to a fraction with a common denominator

4/5    =   8 /10

3/2    =   15 /10       Now you can easily see which is larger.......

Find the AREA of the triangular face     1/2 (base)(height)

    then multiply the area by the LENGTH of the prism to find the volume in ft³

What is \(0.4\overline 8+0.3\overline 7\ ?\)

Hello Guest

\(0.4\overline 8+0.3\overline 7=0.8\overline 6\\\)

\(100\cdot 0.8\overline6=86.\overline6 \)

- \(10\cdot 0.8\overline6=\ 8.\overline6\)

  \(\overline{90\cdot 0.8\overline6=78}\)

\(0.4\overline 8+0.3\overline 7=0.8\overline 6=\dfrac{78}{90}=\color{blue}\dfrac{13}{15}\)

Answer:

5.4

Solution:

12% of 45

method 1:  1% of 45 is .45, so .45x12=5.4

method 2:   10%=4.5.  2%=10%/5=0.9.  4.5+0.9=5.4

0.000388358. That is the at least probability for one specific month, such as January. It should be multiplied by 12 to get: 0.004660296

The same applies to exact probability:  0.000341045  x 12 ==0.00409254 [which agrees exactly with Melody's answer!]

It can be 3,5,6, or 7. (It can't be 4, because that forms a 3-4-5 right triangle.) Thus, there are \(\color{brown}\boxed{4}\) options. 

Not sure

It is 237/40 as a fraction with integer numerators and denominators.

Can you put it as a fractoin plz? Thanks.

Hi Melody:

What do you think of this approach:

First person ==Any month ==12/12

2nd person different from the 1st ==11/12

3rd person different from the first two ==10/12

.

.

And so on to the 12th person ==1/12

So, the probability that the first 12 persons have a different month each is: 12! / 12^12 ==0.0000537232 1709

Or: The probability that at least 2 share the same month is: 1  -  0.0000537232 1709==0.9999462768 - almost a certainty!! Now, I'm stuck on the remaining 6 !!. If the first 12 have each a different month, then the 13th will have 100% chance of sharing his/her month with one of the first 12!! What about the 14th person, and the 15th, 16th, 17th and 18th??
