Fifteen 250 ml glasses contain 3750 ml of the drink, and 750 ml of orange squash.
There are 3000 ml of water in 3750 ml of the drink.
3000 ml of water - 3750 ml of the drink
x l of water - 10 l of the drink
8 litres of water are needed to make 10 litres of this drink.
I think the answer would be 28. Hope this helps!
Answer:
Step-by-step explanation:
Consider the graphs of the 
and 
.
By equating the expressions, the intersection points of the graphs can be found and in this way delimit the area that will rotate around the Y axis.
then 
o 
. Therefore the integration limits are:
and 
The inverse functions are given by:
and 
. Then
The volume of the solid of revolution is given by:
