Answer:
Scale is 1/6
Step-by-step explanation:
Since all sides and angles are identical these are congruent triangles
3 ways to solve:
Scale Factor = DE / AB = 12/72 = 1/6
Scale Factor = DF/AC = 7/42 = 1/6
Scale Factor = EF/CB = 11/66 = 1/6
Answer:
The answer is x=10
Step-by-step explanation:
5/6x - 10 = 1/3x -5 multiple both sides by 6
5x - 60 = 2x -30 move the terms
5x - 2x = -30 +60
3x = 30 divide by 3
x = 10

You are correct
To get the percent of increase, we will follow these steps:
1- get the difference between the two numbers:
difference = 1.8 - 1.2 = 0.6
2- divide the difference from step one by the original number (the number before the increase) and then multiply the quotient by 100 to get the percent as follows:
% of increase = (0.6 / 1.2) * 100 = 50%
Based on the above calculations, the percent of increase in the amount of iron is 50%
