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.

BRAINLIEST INCLUDED! The cost of a pair of boots was $40. They now cost $25. Determine the percent of decrease. Enter your response with an explanation of your process.

Answers

Answer:

37.5 percent

Step-by-step explanation:

First, work out the difference (decrease) between the two numbers you are comparing(which is 15 in this case) . Next, divide the decrease by the original number and multiply the answer by 100.(15/40=0.375 times 100=37.5) If the answer is a negative number, this is a percentage increase

I think the answer would be 37.5% decrease. The boots are $15 less than before so you set 15 over 40 equals x over 100. Cross multiply 40 by x and 15 by 100 to get 40x=1,500. You then divide 1,500 by 40 to get x=37.5 which is your percent decrease. I hope this helped :)

The quotient of a number decreased by 7 and -2 is -10.

Answers

Step-by-step explanation:

First, a quotient is the answer to a division equation.

So its like y÷z=x

X is our quotient.

Since x is -10 when decreased by 7 and -2, we can write:

x-7-(-2)=-10

x-7+2=10

x-5=10

x=15

We now know that x is 15.

Using that, we can write out our equation.

Since you say do not solve, i have purposefully NOT solved this.  

You should use y as a dividend and z as a divisor!

Good luck.

it’s subtraction, so you must subratct 113 by 72, then your answer will be B= 41

so you start with taking 180-113 because that straight line is made up of 2 angles that equal 180, you’ll get 67 then the three angles of a triangle will add up to 180 so you’ll do 67+72=139 and subtract that from 180 to find your missing angle which is 180-139=41 so

Answers

Answer:

6

Step-by-step explanation:

first let's find all the possible combinations excluding 6+6 to get 12 using addition, we exclude 6+6 because we can't have the same integer for different variables. these are 0+12, 1+11, 2+10, 3+9, 4+8, and 5+7(also the other way around but i start with these). using common sense, I started higher because there is no way d = 0 and e= 12, so i went from 5+7 down. through trial and error and some luck, 5+7 was the correct combination. let's insert the numbers with their variables. d = 5 and e = 7. now we figure out, what minus 5 is 7? if you learned fact families in kindergarten, you'd know to find this out you add 5+7, which is 12. now we divide 12 by 2, because it's the same number added together to get this number, so you now get 6+6. does the equation make sense? (6+6) - 5 = 7, that checks out, and 5+7=12.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently.

Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300.

Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn.

Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.

Answers

Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12
