You must get a common denominator of 100. Transfer 594 7/25 to 14857/25 by multiplying 594 by 25. Then multiple 25 and the numerator by 4. For your answer of 59428/100. Then add 59428/100 + 8937/100 for the answer of 68365 then divide it by 100. overall answer should be 683.65. hope this helps
Based on function transformations, the graph of y= cos(2θ), is the same as the graph of <span>y= cos(θ), with a component B of 2, in which case, it means the period is the only thing that differs
well the period for this function will then be </span>

so, the graph of is, the same as y= cos(θ), just shrunk by half horizontally
The answer would be 25 because all of the others are prime numbers, meaning they can only be divided by themselves and 1. So it would be C.
Not sure is this is right but if the chemist wants to make the solution 35% acidic then he can use all of the 30% acid and 5% of the 45% acid.
