A teacher has to grade 50 tests She can grade 4 tests in 6 minutes How long would it take her to grade all the tests?

Around 33 minutes, but 33.3333333 to be more precise. Here's the reason, you have to find a rate so its task over time (4/6) which comes out to .333333333333. So then since you have a rate you'd multiply. So .3333333333333*50= 33.3333333

∙ 9y agoShe takes 6 minutes to grade 4 tests. That is 6/4 = 1.5 minutes for each test.
So 50 tests @ 1.5 minutes each = 50*1.5 = 75 minutes.

A grading machine can grade 48 multiple-choice tests in 1 minute how long will it take the machine to grade 300 test how would you set that up as a proportion?
48 = 300 1____x If it takes 1 minute to grade 48 then it will take "x" amount of minutes to grade 300. The first fraction has to equal the second fraction when they are cross multiplied together. 1 times 300 has to equal 48x. Divide both by 48 and you will get x = 6.25 minutes (6 and a quarter minutes) which equates to six minutes 15 seconds.
How can a spreadsheet be used by a teacher?
Apart from the mundane record-keeping and grade calculation tasks, a teacher can produce unique answer keys for mathematically oriented tests. As an example, the teacher can give chemistry tests where the 'seed' numbers for the quantities would be the students' birthdays or some multiple thereof. If the student was born on the 15th, 15 would be the seed. A typical question would be: "How many grams of water would be produced by completely reacting (seed x 3) grams of oxygen with excess hydrogen?" That makes it unlikely that students could simply copy correct answers from neighbors. Grading is a snap because, for each test, the teacher would simply update the seed number on the spreadsheet grading key.
You got a 61 percent on your test and you had a 92 percent in the class the tests are worth 70 percent of your grade what would your new grade be?
it depends how many grades in the class you have.
If you missed 4 on a test with 26 questions what is your finnal grade?
That depends on your teacher's or schools practice. If they "grade on a curve" then all the tests taken will be distributed on a Gaussian bell probability curve. So if you are the only one who missed 4 questions and everybody else missed more you will get the highest grade; but of you are the only one who missed 4 questions and everybody else mised fewer, then you will get the lowest grade. In my school only a few teachers graded on a curve; most would have given a B for missing 4 out of 26 equally important questions. UH UH!If you missed 4 out of 26, you would still get a A-.I aked my teacher and she said yes.

Would shredding services be helpful to a teacher?
I would think that a shredding service would not be helpful to a teacher. Teachers need to keep too many files and tests so they can look at a students work and evaluate how they are doing. If they get rid of anything and make a mistake on a students grade or paper they need to be able to see where they made a mistake and fix it.

What is a curve grade?
Alot of times if a class makes a low grade, your teacher will decide to "curve" it. All this means is that he/she is giving you extra points. For example, if you make an 89 and your teacher gives a 3 point curve, your new grade would be a 92.
