Sin 30= x/8
X= sin 30*8
X=4
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!

Step-by-step explanation:

There are approximately 4 weeks per month.
Mr. Gleason will take home 1100 x 4 weeks = $4,400 per month.
The total budget - his take home pay is the amount his wife will need to make:
5,600 - 4,400 = $1,200
Now divide the total amount she needs to make by how much she brings home per hour:
1,200 / 10 = 120
She needs to work 120 hours per month.
The answer is D.
