one common factor of 2 numbers is 40 another common factor is 10 if both numbers are less than 100 what are the two numbers
Answers
Answer 1
Answer:
so, if one common factor is 40, then they also have all the factors of 40 in common: 2,4,5,8,10... so we don't need to know that the other common factor is 10.
but there are only two multiples of 40 smaller than 100: 40 and 80. and if those numbers are not the same number, then they must be 40 and 80!

Convert 9 1/2 into a mixed fraction: 19/2. Now, multiply with 6 which in fraction form is 6/1 19/2 times 6/1 equals 114/2
Now you can divide 114/2 which is 57 inches squared.

The right answer for the question that is being asked and shown above is that:
This can be answered using the Pythagorean Theorem. h2 = a2 + b2 h = square root (8^2 + 5^2) h = square root (64 + 25) h = square root (89) in h = 9.4 in
So the correct answer is 9.4 in given the dimension 5 inches and 8 inches.
Is 102 divisible by 4 5 6 9 or 10 PLEASE HELP I AM FAILING AND ABOUT TO CRY!!!!
Answers
It can't be divided by 5 or 10 since when you count by 10's the numbers end in only zeros and when you count by 5 it is either 5 or 0 (5, 10, 15, 20 and so on).
9 will only work if the digits in the answer add up to 9. 18: 1+8=9 99: 9+9=18 and 1+8=9 So it can't be divided by 9 102: 1+0+2=3 (not 9)
That leaves 6 and six works - here's why. There is a rule for 3's that says that the sum of the digit must add up to 3, 6 or 9. Look: 3x1 = 3 3 x 2 = 6 3 x 3 = 9 3 x 4 = 12 and 1+2=3 3 x 5 = 15 and 1+ 5 = 6 3 x 6 = 18 and 1+ 8 = 9 3 x 7 = 21 and 2 +1 = 3 and so on - do you see the 3,6,9 pattern repeating.
Six follows the same rule except the number must be even. Look above to see that 6 works with 6, 12 and 18 but not the others. So 102 is divisible by 3 (1+0+2 = 3) AND it is an even number - therefore it is divisible by 6. Here's proof: 6 x 15 = 90 and 102 is 12 more than 90 and six goes into that 12)
I hope that this will help you feel better. I don't want you to cry. :-)
