First find how many units of solution there is:
500* 2% = 500(.02) = 10 units
You need 10 units of solution in 'x' units of a 10% solution.
x*10% = 0.1x = 10 units -----> x = 10/0.1 = 100
100 units are needed
Answer:
rational function is the correct answer
Lxwxh using your numbers its 3x3x3 or 3³ so your answer is 27
18 is the answer because eighteenth has nth in the ending
-8
Step-by-step explanation:
The gradient or slope of a curve y is simply the derivative of the curve at a point x. So we can proceed as follows

Evaluated at x = 2, the gradient of the slope is
