Answer:
0.012
Step-by-step explanation:
0.6/48.24
1. multiply numerator and denominator by 100 to get 60/4824
2. divide 60 by 4824
3. you get 0.012
( i would've written out how to get that answer but there are about 10 steps and it's really hard to type them out)
Answer:
The explanation in the procedure
Step-by-step explanation:
we know that

In this problem is correct to use the measurement
instead of
because

therefore

Answer:
The volume of the solution with 20% acid is 27 gallons and the one with 10% acid is 18 gallons
Step-by-step explanation:
Myra needs to mix "x" gallons of the solution with 20% and "y" gallons of the solution with 10%. The volume of the final solution must be 45 gallons, therefore:
x + y = 45
The concentration of acid of the final solution is:
0.2*x + 0.1*y = 45*0.16
0.2*x + 0.1*y = 7.2
Therefore we have a system of equation:
x + y = 45
0.2*x + 0.1*y = 7.2
We need to multiply the first equation by -0.1:
-0.1*x -0.1*y = -4.5
0.2*x + 0.1*y = 7.2
We now sum both equation:
0.1*x = 2.7
x = 2.7/0.1 = 27 gallons
y = 45 - 27 = 18 gallons
Answer:
I believe the answer is the second option, t is the independent variable and a is the dependent variable.
Step-by-step explanation:
This is because the amount of juice Marshall can make depends on the number of tomatoes Marshall has. Therefore, a is a dependent variable and option B is the answer.
