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.

What is the value of the variable in the equation, r-17=22 *


please help me with this for brainliest and a cupcake

Answers

Answer:

Step-by-step explanation:

Example

With numbers

18+4=22

18+4−4=22−4

18=18

With variables and numbers

x+4=22

x+4−4=22−4

x=18

We subtract 4 from both sides. Example

Which of the following numbers is a solution to the equation? x = 2, 7,  or 8?

14−x=7

Here you are given the numbers 2, 7 and 8. One of these numbers will satisfy the equation. If you don't know the solution right away, you can investigate which of the given numbers gives results in the correct answer by plugging in the different values of x.

Answer: x=7

Example

8x=64

8⋅x=64

Which number should you multiply 8 by to get a product of 64? By using the multiplication table, we know that the number is 8.

8⋅8=64

When we solve an equation, we figure out what value of x (or any other variable) makes the statement true (satisfies the equation).

Answer: r = 39. Add 17 to both sides and you’re left with r on the left and 39 on the right.

On a recent math quiz, Georgia got 35 out of 40 questions correct. Rounded to the nearest percent, what was Georgia's score on this quiz?

Answers

Answer:

80%

Step-by-step explanation:

Answer

(87.5) rounded would be 88

Step-by-step explanation:

35/40 divid eatch side by 2 to get 17.5/20 now the fraction can go into 100 eveanly. 20x5=100 and 17.5x5=87.5. 87.5/100

Choose Yes or No to tell if the fraction 3/5 will make each equation true.
7/20 + 3/5 = 19/20 (yes/no)
3/5 + 3/10 = 3/15 (yes/no)
1/2 + 2/3 = 3/5 (yes/no)
1/10 + 1/2 = 3/5 (yes/no)

William gets a student loan to pay for his college tuition. He borrowed $2,500 for 10 years at an interest rate of
8%. How much will William pay in interest on this loan?

Answers

Answer:

2897.31

Step-by-step explanation:

I'm going to assume two things

The interest rate is compoudning annually

There is only one payment (at the end of the 10 years)

To find the amount of interest paid on this loan we first need to calculate the future value (or accumulated value)

FV=PV(1+i)^n

Plug in our numbers

2500(1+.08)^10

Run this through a calcuatlor and get 5,397.31

This is the future value and the question is asking for the interest paid which is just the FV-PV

Which means we have

5,397.31-2500

our answer is 2897.31

Answer:


2897.31
