Answer:
<em><u>Part A: </u></em>(40/100)*x = 1 where x is the total contents of the bottle.
<em><u>Part B</u></em>: 1.5 Liters = the Lemon Juice
Step-by-step explanation:
Part A
Let the full contents of the bottle = x
<em><u>Equation</u></em>
Since 60% of it is lemon juice, then 100% - 60% = 40% must be water.
(60/100) * x = ?? Equation for Lemon Juice. You have to solve the water first.
(40/100) * x = 1 Equation for water
Part B
(40/100) * x = 1 change the 40% to a decimal
0.4x = 1 Divide by 0.4
x = 1/0.4 = 2.5 L
Now to find out the amount of lemon juice
0.6 * 2.5 = Lemon Juice
1.5 L = the amount of Lemon Juice.
It will take them 4.24 hours together to paint the area together
Step-by-step explanation:
If Emily takes eight hours to paint the area then she will paint 1/8 of the house in one hour
Similarly, if Mike can paint the same area in 9 hours, then he will paint 1/9 of the same area
Let x be the number of hours in which they will together paint the area.
If x hours are taken by them to paint the area then 1/x of the area will be painted in one hour
So,

It will take them 4.24 hours together to paint the area together
