.0000 LOL Show WHAT to 4 decimal places?
3 x 5 = 15 so all multiles of 15 are marked with two = 10
3*7 = 21 all multiples of 21 (105 already marked) = 6
5x7 = 35 35 70 105 and 140 (but 105 already marked) = 3 total 19
Start by graphing the three points and the equation......Have you done that yet?
Just finish this:
(3x^2 + 5x^2 + 5x^2) + ( x -3x +5x) + ( 4-8+1)
I'm glad neither of us can add ! LOL ........ ~EP
Jane rate 1 job / 15 days John rate = 1 job/10 days
together 1 job / ( 1/15 + 1/10) = 1/ ( 2/30 + 3/30) = 1/ ( 5/30) = 30 / 5 = 6 days
This just seems needlessly tedious........
Go! , asinus, GO! LOL ......
x and 8x if x is a perfect square then
sqrt (x) = integer then sqrt (8x) = integer * sqrt 8 you are stuck with sqrt 8 as a factor.....not an integer
10 * 10 * 10 * 1/3 = 500 cubic inches of water
then add 10 cubic inches of ice = 510 in3 total
Are you sure you posted the numbers correctly? In particular the 20 number.....but it could be oneof the others....is there only 30 students?
The numbers don't add up....here is a Venn Diagram (bottom nember is 13)
