Answer:
you need 100ml of 5X TAE and 400ml of water.
Step-by-step explanation:
You need to use a rule of three:
where:
and
Therefore:
Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
Well. To put it simple, let's start off with an equation to help figure out this problem:
16/8 = ? / 2.55
(16 ounces are in a pound btw)
8 x 2 = 16
2.55 x 2 = 5.1
meaning:
16/8 = 5.1/2.55
Answer: 5.1 ounces of barley can be purchased with $2.55
Hope this helped! :D
I pretty sure the answer is 1 !!!
Answer:
Step-by-step explanation:
Case I: use common logs:
2x log 3 = log 4, or 2x(0.47712) = 0.60206
Solving for x, we get 0.95424x = 0.60206, and then x = 0.60206/0.95424.
x is then x = 0.631
Case II: use logs to the base 3:
2x (log to the base 3 of 3) = (log to the base 3 of 4)
This simplifies to 2x(1) = 2x = (log 4)/log 3 = 1.262. Finally, we divide this
result by 2, obtaining x = 0.631
Well I would say r×±3=4 that is what I would say it is but I don't know if it's right
