I got the answer c and if I am correct then it is repeating also
Answer:
169 : 289
Step-by-step explanation:
Since the figures are similar then
linear ratio of sides = a : b, then
ratio of areas = a² : b²
ratio of sides = 52 : 68 = 13 : 17
ratio of areas = 13² : 17² = 169 : 289
Answer:
Step-by-step explanation:
Out of 30 numbers, half is multiple of 2 and the third is multiple of 3.
We have 15 even numbers and 10 multiples of 3. Out of 10, half is even numbers and therefore counted twice.
<u>So we subtract 5 to get:</u>
<u>If we chose one ticket at random the probability is:</u>
- P(2x or 3x) = 20/30 = 2/3 or 66.66%
Based on your comment about the question, You would have to subtract 55 - 12, to find the remaining amount to get 12 up to 55, which would be 43 ;D
