<u>Given:</u>
Ratio of white and blue paint is 2:3
Total quantity of paint is 20 litres
<u>To find:</u>
Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7
<u>Solution:</u>
The ratio 2:3 totals 20 that is 
So, the quantity of white paint in the mixture is 
and the quantity of blue paint in the mixture is 
Now, to get the final ratio as 1:7, Mary should have 
of blue paint. So, she need to add 
.
Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

Answer:
<h2>BC = 11.9</h2>
Step-by-step explanation:
To solve for BC we use sine
sin ∅ = opposite / hypotenuse
From the question
AC is the hypotenuse
BC is the opposite
So we have
sin 58 = BC / AC
sin 58 = BC / 14
BC = 14 sin 58
BC = 11.87
BC = 11.9 to one decimal place

Step-by-step explanation:
The answer is <span>25; it represents the hourly wage for the worker
</span>
<span> y = 8x + 25
x is hours
y depends on x hours so y-intercept represent the hourly wage.
The y-intercept is y when x = 0:
y = 8x + 25
x = 0
____
y = 8 * 0 + 25
y = 0 + 25
y = 25</span>
