Aisha measures the length of a sheet of paper and finds that it is 29 cm long. The label on the package indicates that the paper length is 32 cm. Calculate the percentage error in the measurement.
Answers
Answer:
just do the step by step and you'll probably get it because it's quite simple but hard for me to explain so just read this!
Step-by-step explanation:
In making any measurement, the chances are that our results will not be absolutely accurate. We can often compare our results with some standard or accepted value to see how closely they agree. But how much error can be allowed before the result becomes meaningless?
As you may guess, the amount of error that is acceptable varies with the situation. Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles. If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!
Percentage Error = measured value - accepted value x 100%
accepted value
Suppose, you measured the length of a table and obtained a measurement of 202 cm. A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.
The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.
I dont know the answer but I hope this helped!

Which equation can be used to solve the problem?
75 percent of what number is 150?
StartFraction 75 times 1 Over 150 times 1 EndFraction = StartFraction 75 Over 150 EndFraction
StartFraction 150 times 2 Over 75 times 2 EndFraction = StartFraction 300 Over 150 EndFraction
StartFraction 200 times 2 Over 75 times 2 EndFraction = StartFraction 400 Over 150 EndFraction
StartFraction 75 times 2 Over 100 times 2 EndFraction = StartFraction 150 Over 200 EndFraction
Answers
Answer:
200
Step-by-step explanation:
multiplying both sides by 100 and dividing both sides by 75, we have
X = 150 x 100/75
X = 200
A car has 15 gallons of gas in its tank. The car travels 35 miles per gallon of gas. It uses 135 of a gallon of gas to go 1 mile. How much gas does it use to go 100 miles?
Answers
2.86 gallons
Step-by-step explanation:
If 1/35 gallon of gas = 1 mile
To travel 100 miles,
1/35 * 100
= 0.0286 * 100
= 2.86 gallons
Therefore, the car needs 2.86 gallons of gas to travel 100 miles

Answer:
2.73 8.75
Step-by-step explanation:
n = 1
1 (DOUBLE) = 1+1 = 2
2 +3/4 = 1.5
1.5 +2 = 3.5
3.5 x 0.22 = 0.77
3.5 - 0.77 = 2.73
n = 1
1 + 3/4 = 1 + 0.75 = 1.75
1.75 (DOUBLE) = 3.5
3.5 x 2 1/2 = 8.75

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
Answers
Answer:
yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags
Step-by-step explanation:
yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8 9-ounce bags = 72 and that is less then what you have.
Answer:
Yes there will be enough popcorn for eight 9-ounce bags.
Step-by-step explanation:
" eight 9-ounce bags"
Basically
"72 ounces"
"12.75 ounces of popcorn in 3 minutes"
Basically
We need to find out how much popcorn we can make in "One Minute"
12.75÷3=4.25
Now we need to find out how much it can make in "Ten Minutes"
4.25×10=42.5
"18 ounces of popcorn in 4 minutes."
Basically:
We wanna find out how much it can make in "One Minute"
18÷4=4.5
"makes popcorn for 10 minutes"
Basically:
We need to find out how much popcorn it can make in "Ten Minutes"
4.5×10=45
Add (45) and (42.5)
45+42.5=87.5
So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.

Look at the picture and answer the question: What is the length of QS?
Answers
Step-by-step explanation:
firstly draw the triangle and label it. (you will find the picture down)
Now this remind us with the cosine rule. (you will find the picture down)
This rule says that the square of the given length of the side of a triangle is equal to the sum of the squares of the length of other sides minus twice their product and multiplied by the cosine of their included angle.
So using that rule we can say that:
[tex]QS^{2}[/tex] = [tex]QR^{2} +SR^{2} - 2(QR)(SR)(cosR)[/tex]
square root both sides, so you will have QS alone in one side.
QS = [tex]\sqrt{ [QR^{2} +SR^{2} - 2(QR)(SR)(cosR)]}[/tex]
plug in the values we have and y=this will yield:
QS = [tex]\sqrt{ [11^{2} +16^{2} - 2(11)(16)(cos38)] }[/tex] = 9.98099267 = 10
