Answer:
Step-by-step explanation:
The water has to be 100% - 60% = 40%
100% represents both water alcohol (I think that's what you meant).
40% of 250 = 40/100 * 250 = 10000/100 = 100 mL
So 100 mL = water
150 mL = alcohol.
Answer:
Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
When you have the prism's base area (
) you just have to multiply:

(V = volume)

Answer:
G= 56/3
Step-by-step explanation:
56/3 is an ugly number if you ask me but it was the answer I got, and here's how I got it!
So first off you want to change -49 to a positive and add it to 7! This will change the equation to 3g=56, from here just divide 56 by 3! Which if you don't turn into a fraction it'll just be a really long number. So g=56/3! If you have any more questions feel free to ask!
Do 14 times n which give you 14n. and divide by 3.
Answer: (14n)/3
