Monica [59]

A scientist needs 60 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution. How many liters of each does he need to make the needed 60 liters of 60% acid solution?

----------------

Equation:

acid + acid = acid

----------------------

0.40x + 0.70(60-x) = 0.60*60

-----

40x + 70*60 - 70x = 60*60

 

-----

-30x = -10*60

x = 20 liters

----

Gabe needs 20 liters of the 40% solution.

He also needs 40 liters of the 70% solution.

I'm rather stuck on this question
White raven [17]

Answer:

m<a = 30°

m<b = 90°

m<c = 60°

Step-by-step explanation:

Angles a, b, and c are all angles on a straight line.

Angles on a straight line add up to 180°.

Therefore, a + b + c = 180°

Given that a:b:c = 1:3:2, the measure of each can be calculated as follows:

Measure of each angle = the ratio proportion of that angle ÷ total ratio proportion * 180°

m<a = \frac{1}{6} * 180 = 30

m<b = \frac{3}{6} * 180 = 90

m<c = \frac{2}{6} * 180 = 60
