10÷2/3 = 10*3/2 = 15
ok, thanks
For this problem you can work backwards. If it is 6 years after Jacob is three times his age. First, subtract 6 from 39. 39 - 6 = 33. Then, divide by 3, 33÷3 = 11. So his age is 11.
g(2) = 2(2^2) + 2(2) - 1 which equals 11. g(11) = 2(11^2) + 2(11) - 1 which is 263.
the 2 fractions aer 1/4 and 2/3. If u check this 1/4 * 2/3 is 2/12 which equals 1/6. If u add the 2 1/4 plus 2/3 the sum is 11/12.
The probability that this will happen is 1/54. If you count the numer of ways you can get 18 and 17, (6,6,6),(6,6,5),(6,5,6),(5,6,6) that is 4 ways. There are 6^3 = 216 total possibilities 4/216 = 2/108 = 1/54
the answer is 4 because in the smaller triangle the hypotenuse is twice 1 so it is 2. In the larger triangle the hypotenuse is twice 2 so 2 times 2 is 4 so x=4.
10 choose 2 is 45 because 10!/(10-2)!*2 equals 10!/8!*2 10!/8! is 90 90 divided by 2 is 45. 8 choose 3 is 56. 45*56 is 2520 so the answer is 2520.
45√3
are the triangles equilateral?
