Answer:
0.5
Step-by-step explanation:
Answer:
2.8 in
Step-by-step explanation:
The volume of any shape is given as the product of base area and height. Therefore, V=Ah
Where A is cross sectional area, h is height
For a triangular, the cross sectional area is given by ½lw where l is length and w is width.
Now v=½lwh
Given that v=4 in³
4=½lwh
8=lwh
Considering the given choices, l can be 2.8 in
Add the two numbers in your ratio and divid if from one hundred
This would equal 20
So to find the percentage for the colours as they are time the two ratio number to get 40:60 this is also the percentages.
If you add five more blue parts in to the ratio and leave the red alone you will get 2:8 this would give you a 80% blue part.
So the answer is
5 parts of blue are needed to make the mixture 80% blue.
