Answer: 30 m
Step-by-step explanation: i think this is correct and i apologize if it’s not, but there’s two ways you could do this. 1: initial X increase/decrease in decimal form. in this case, 24 X 1.25 (125% in decimal form). 2: you could figure out what 25% of 24 meters is in the same way as method 1, and then multiply that answer by five to get 125%. i reallyyy hope this helped and if it’s wrong i’m really sorry, but good luck!

The distnace around a two dimensional shape
In this question, you want to make 10 liters 20% concentration solution by mixing 5% and 40% concentration. There should be multiple answers to this question. Assuming that the total volume of 5% and 40% solution equal to 10L(no solution wasted), then you can determine the volume of solution needed. The formula should be:
if x would be the of volume 40% solution, then the volume of 5% would be:
10 L= 40% solution volume+ 5% solution volume
10 L= x + 5% solution volume
5% solution volume= 10l-x
Then the volume calculation would be:
volume20%*concentration20%= volume40%*concentration40% + volume5%*concentration5%
10 liter * 20%= x liter*40% + (10- x) liter*5%
10l * 20%= x liter * 35% + 10 liter*5%
x liter *35 = 10l * 20 - 10l *5= 10l*15
x liter = 10l *15/35= 4.28 L= 4.3L
The volume of 40% solution= 4.3L
The volume of 5% solution= 10L- 4.3L= 5.7L
