How many gallons of a 20% acid solution should be mixed with 30 gallons of a 40% solution, to obtain a mixture of 30% acid solut
Alexeev081 [22]

Answer:

30 gallons of 20% acid solution should be mixed.

Step-by-step explanation:

Let x gallons of a 20% acid solution was mixed with 30 gallons of a 40% solution, to obtain a mixture of 30% acid solution.

Therefore, final volume of the solution will be (x + 30) gallons.

Now concept to solve this question is

20%.(x) + 40%.(30) = 30%.(x + 30)

0.20(x) + 0.40(30) = 0.30(x + 30)

0.20x + 12 = 0.30x + 9

0.30x - 0.20x = 12 - 9

.10x = 3

x = \frac{3}{0.1}

x = 30 gallons

Therefore, 30 gallons of the 20% acid solution should be mixed.

10 to the 6th power multiplied by what equals 10 to the 18th power
m_a_m_a [10]
 
You're asking

            (10⁶) times (10^p) = 10¹⁸ .

When you multiply two numbers that have the same base
but different exponents, you just add the exponents.

So                                         6 + p = 18

Subtract 6 from each side:          p = 12 .

                 10⁶  x  10¹²  =  10¹⁸ .
