How do you round 87,147 to the nearest 100

I want to take you through the steps of rounding so that you can do it with this number, and any other number.

Step 1 - Find the column in question.
Step 2 - Look to the number immediately to the right of this number.
Step 3 - If this number is great than or equal to 5, add 1 to the column in question.
Step 4 - If this number is 4 or less, don't add the 1
Step 5 - Since this number is to the left of the decimal, make all numbers to the right of this number a 0.

Using the example provided of 87,147 to the nearest hundred.
The hundreds column is the third column to the left of the decimal. Ones, Tens, Hundreds. In this case, the 1.

The number immediately to the right of this number is 4.

This number is 4 or less, so we don't add 1 to the hundreds column.

We set all numbers to the column in question to be 0.

I get 87,100.

Good luck.

Let me know if you have any questions.

Y=x^2-7x+4, y=-8x^2+56x-86

Since the y-variable is isolated in both equations, set the two right sides of the equations equal
Combine all like terms on one side of the equal sign
9x^2-63x+90=0. factor out the 9 to get 9(x^2-7x+10)=0
Now solve the equation (x^2-7x+10)=0. The solutions are x=5 and x=2
Calculate the y-value tof be y=-6
The two solutions are (2,-6) and (5,-6)
Graphically, here is how the two curves intersect. One intersection point in the screen capture is (2,-6). You can read that the other intersection point is (5,-6)

Write each quadratic equation in standard form. . identify the values of a,b,and c. . ...

  • Solve (x + 2)(x + 3) = 12.
    It is very common for students to see this type of problem, and say:
      "Cool! It's already factored! So I'll set the factors equal to 12 and
      solve to get x = 10 and x = 9. That was easy!"

    Yeah, it was easy; it was also (warning!) wrong. Besides the fact that (10 + 2)(9 + 3) does not equal 12, you should never forget that you must have "(quadratic) equals (zero)" before you can solve.
    So, tempting though it may be, I cannot set each of the factors above equal to the other side of the equation and "solve". Instead, I first have to multiply out and simplify the left-hand side, then subtract the 12 over to the left-hand side, and re-factor. Only then can I solve.
      (x + 2)(x + 3) = 12
      x2 + 5x + 6 = 12
      x2 + 5x - 6 = 0
      (x + 6)(x - 1) = 0
      x + 6 = 0 or x - 1 = 0
      x = -6 or x = 1
    Then the solution to (x + 2)(x + 3) = 12 is x = -6, 1

One number is 11 more than another number. Find the two numbers if three times the larger number exceeds four times the smaller number by 4.

Do you need help doing your homework?

If so, here's a first attempt. It may be correct, and it may not be.
It's up to you to understand the process, and to make any needed corrections.

X minus 11 equals Y.
So, X is larger than Y.
So, 3 times X minus 33 equals 3 times Y.
Thus 3 times X equals 3 times Y plus 33.
Also, 3 times X minus 4 equals 4 times Y.

So, (3 times Y plus 33) minus 4 equals 4 times Y.

Thus 0 times Y plus 29 equals 1 times Y.

So, Y equals -27.

One divided by zero equal to infinity,why

This is from wikipedia:

When division is explained at the elementary arithmetic level, it is often considered as a description of dividing a set of objects into equal parts. As an example, consider having ten apples, and these apples are to be distributed equally to five people at a table. Each person would receive 08f04ddc176e330c394dee13c81120bb.png = 2 apples. Similarly, if there are 10 apples, and only one person at the table, that person would receive a4e39866af487b126593d0aaaa7d5ab9.png = 10 apples.

So for dividing by zero - what is the number of apples that each person receives when 10 apples are evenly distributed amongst 0 people? Certain words can be pinpointed in the question to highlight the problem. The problem with this question is the "when". There is no way to distribute 10 apples amongst 0 people. In mathematical jargon, a set of 10 items cannot be partitioned into 0 subsets. So ed9f7cc4d52d9a98f859e594a77b31b7.png, at least in elementary arithmetic, is said to be meaningless, or undefined.

Similar problems occur if we have 0 apples and 0 people, but this time the problem is in the phrase "the number". A partition is possible (of a set with 0 elements into 0 parts), but since the partition has 0 parts, vacuously every set in our partition has a given number of elements, be it 0, 2, 5, or 1000. If there are, say, 5 apples and 2 people, the problem is in "evenly distribute". In any integer partition of a 5-set into 2 parts, one of the parts of the partition will have more elements than the other.

In all of the above three cases, ed9f7cc4d52d9a98f859e594a77b31b7.png, 760e263bbe0c0151e575941291b5c190.png and 285df902469bec95c2ddff4ea625c573.png, one is asked to consider an impossible situation before deciding what the answer will be, and that is why the operations are undefined in these cases.

To understand division by zero, we must check it with multiplication: multiply the quotient by the divisor to get the original number. However, no number multiplied by zero will produce a product other than zero. To satisfy division by zero, the quotient must be bigger than all other numbers, i.e., infinity. This connection of division by zero to infinity takes us beyond elementary arithmetic (see below).

A recurring theme even at this elementary stage is that for every undefined arithmetic operation, there is a corresponding question that is not well-defined. "How many apples will each person receive under a fair distribution of ten apples amongst three people?" is a question that is not well-defined because there can be no fair distribution of ten apples amongst three people.

There is another way, however, to explain the division: if we want to find out how many people, who are satisfied with half an apple, can we satisfy by dividing up one apple, we divide 1 by 0.5. The answer is 2. Similarly, if we want to know how many people, who are satisfied with nothing, can we satisfy with 1 apple, we divide 1 by 0. The answer is infinite; we can satisfy infinite people, that are satisfied with nothing, with 1 apple.

Clearly, we cannot extend the operation of division based on the elementary combinatorial considerations that first define division, but must construct new number systems.

The settings on my Peavey Q215FX dual 15 band graphic equalizer w/fls have been changed and I am unsure where they were set at and what the correct settings should be.

Assuming that you eq is installed in your system correctly add a source like a cd of the type of music you will be putting through the system. Now starting at 0 on all frequencies adjust to your liking. Try to avoid going above 0 as much as possible because this will be adding to that particular frequency and could damage your speakers if done incorrectly.

If there is too much bass lower your sliders to the left. If there is not enough highs boost the sliders to the right up to about half way then start decreasing the bass to get the desired effect. Small increments is important.

I found that if you go to your local music store the people there are more than willing to help you.
