It is given in the question that in the lemon squash 2 parts concentrate is added to 5 parts of water. Thus it makes the concentrate to water ratio as 2:5 or . Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:
Where x is the amount of water to be added, in ml (milliliters).
Cross multiplication of the above equation will give us:
Dividing both sides by 2 we will get:
Thus, if we put 90ml of concentrate in a glass, the water that should be added must be 225 ml.
Step-by-step explanation:
Area of one side of the shed
5*4=20
she painted 4 sides so 20*4 =80
Triangle that is part of the pyramid as the roof of the shed has a side of 5. Using the Pythagorean theorem,
we need to find the square root of 18.75 to find the height of the triangle which is
that is the height
(base x height) /2 is the formula for a right triangle. there are 2 of these right triangles per side of the roof. so we need to multiply the numbers by 8
this number gives us 43.30127019
we can finally add that number to 80 to get the total surface area Zoe painted which is 123.3012702
