Sin2x = 2 sinx cosx
so 12 sinx cosx = 6 sin2x Answer
DBJ + ABJ = 90
DBJ = ABC
DBC + ABC = 90
JBC + DBC + ABJ = 90
And last but not least:
ABJ = 28
Answer:
17:3 is 68:12 simplified
15 slices will be eaten in 10 minutes
Step-by-step explanation:
first off 17:3 is 68:12 simplified (both 68 and 12 go into 4 resulting in 17 and 3)
you have to divide 10 by 2 which will give you 5
and then multiply by 3
to get 15
3) Answer: 8:9 (Defense:Offense)
16 and 18 need to be simplified. They're both divisible by 2, getting 8:9, and can't be simplified any more or they won't be whole numbers.
4) Answer: 1:3 (Hit:Bat times)
5 and 15 are divisible by 3, making 1 and 3.
5) Answer: 1:65 (Hours:Miles)
3 and 195 is divisible by 3. (195 is divisible by 3 because 1+9+5=15, getting the sum of numbers will get a smaller number, and if that number, 15 in this case, is divisible by 3, then the larger number is divisible by 3. 195/3=65, so 1:65
6) Answer: 1:3 (Potatoes:Servings)
8 and 24 is divisible by 8, getting 1 and 3.
