You'll need to give a bit more information for the question to be answered. You can only calculate the percentage of error if you know what the mass of the substance *should be* and what you've *measured* it to be.
In other words, if a substance has a mass of 0.55 grams and you measure it to be 0.80 grams, then the percent of error would be:
percent of error = { | measured value - actual value | / actual value } x 100%
So, in this case:
percent of error = { | 0.80 - 0.55 | / 0.55 } x 100%
percent of error = { | 0.25 | / 0.55 } x 100%
percent of error = 0.4545 x 100%
percent of error = 45.45%
So, in order to calculate the percent of error, you'll need to know what these two measurements are. Once you know these, plug them into the formula above and you should be all set!
You didn't supply any rules or constraints so.... 1 in., 1 in., and 1 in.
You can use the Pythagorean Theorem to check if the side lengths are appropriate.
–this is true.

Answer:
2:1
Step-by-step explanation:
I think I'm not 100 percent sure
Answer: 115% increase
Step-by-step explanation: To solve, we need to subtract the first value fro the second value. The formula is Percent Change = ((Second Value – First Value) ÷ First Value) x 100%
700,000-326,000=374,000. Then, divide the difference by the first value.
374,000÷326,000=1.1472392638≈1.15
1.15×100%=115%
Thus, the approximate percent of increase in the bales produced during that 21-year period is 115% increase
