Answer:
24
Step-by-step explanation:
u can do mental math or use a calculator
Drawing this on a paper, will give you 5280 west, then 2460 north and then straight back to the start.This will give you a triangle. The way to answer this is to first compute the total square footage of the area in problem, then divide by 43,560 which is the square footage in an acre.
So putting this mathematically: 5280 x 2460 = 12988800 (total sq footage in the box) / 2 (cut it in half to get the square footage of the triangle)
= 6494400 (total square footage of triangle) /43560 (square footage in an acre
= 160 acres.
The percentages for each acid are:
- 0% acid ⇒ percentage disolved = 0%
- 33% acid ⇒ percentage disolved = 1%
- 66% acid ⇒ percentage disolved = 2%
- 100% acid ⇒ percentage disolved = 4.2%
<h3>
How to get the percentages?</h3>
Here we just need to use the given formula:
For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:
For the 33% acid we have:
- initial mass = 10.1g
- final mass = 10g
Then:
For the 66% acid:
- initial mass = 10g
- final mass = 9.8g
for the 100% acid:
- initial mass = 9.9g
- final mass = 9.5g
