Answer:
5.429
Step-by-step explanation:
The decimal representation of 5 3/7 is the repeating decimal ...
It can be rounded to any desired precision, such as ...
- 5.4
- 5.43
- 5.429
- 5.4286
- 5.42857
- 5.428571
- ...
The answer is C bc they just add the 0
do you have something you want us to answer or....
My teacher taught me a simple equation for these types of problems:
(percent of solution × amount of solution) + (percent of solution × amount of solution) = (percent of solution × total amount of solution)
in simple terms: %amount + %amount = %total amount
We know don't know how much gallons of 60% solution we need so it will be represented as x. We dont know the total amount either so it would have to be both solutions added together so 50 + x. Now lets solve:
(0.60)(x) + (0.24)(50) = (0.50)(50 + x) simplify/ distribute
0.6x + 12 = 25 +0.5x get all xs on one side and numbers on other
0.1x + 12 = 25
0.1x = 13 divide both sides by 0.1 to find x
x = 130
You need 130 gallons of 60% solution.
