1) find the perfect square closest to the number
2) take that square root, and then divide your number by that number
3) take the average of the perfect square root (the whole number) and the result of dividing your original number by that root.
Example: Approximate square root of 27
Closest perfect square: 25
Square root: 5
27 ÷ 5 = 5.4
Average between 5 and 5.4 = 5.20
5.2² = 27.04. Fast and not a bad approximation!
50/50, because there are three colors and 6 beads so...
Answer:
(x+2)
Step-by-step explanation:
factor out the equation and get
(x+2)(6x-5)
Answer:
6 2/3 mL
Step-by-step explanation:
Multiply thru by 100 to get:
1000 + 60x = 30*40 + 30x
30x = 200
x = 6 2/3 mL (amt. of 60% solution needed in the mixture)
