David is the first 4 in the ratio 4:3:4. We know that David gets 44 sweets. We also know that Paul gets 44 sweets because he is the other 4 in the ratio. To find out how many sweets 3 is equal to, you need to find the unit rate. To do this, you can divide 44 by 4 to know how much 1 equals. When you divide 44/4, you get 11. This means that 1 is 11. To find out what three is, you can multiply 11 by 3 to get 33. The question asks how many sweets are there altogether, so you must add 44+33+44. This equals 121.
30^2=900 55^2=3025 900+3025=3925 Square root of 3925==64.6298 This is Pythagoras Theorem where A^2+B^2=C^2 square root of C is answer hope this helped, the answer is 64.63
