No, but the ignorance of math can be very painful  --  spending too much for a loan, buying something you cannot afford, not having the right amount of insurance, voting for persons who do not understand economics, etc.

Only when you laugh........

Math is dumb.

YEAH....BRITTANYJ....!!!!....Finally....a team we can agree on !!!!!!....Steeler fan for life....!!

Do multiplications (from left ot right) before you do additions and subtractions.

35 - 3 * 3 * 2 + 5

=  35 - 9 * 2 + 5

=  35 - 18 + 5

Now do the additions and subtractions, from left to right:

=  17 + 5

=  22

Here is a bee:

That's as much as  know about it......

I suggest that:

1) you graph each one; this will tell whether or not the rocket was ever high enough (100 + feet) and whether or not if flew far enough (where was the rocket when x = 80?).

2) you replace x with 80 in each equation to see where the rocket was when x = 80. If the value is close to zero, it could have started the fire; if it is not close to zero, it couldn't have started the fire.

Some possibilities are:

--  use the Pythagorean Theorem

--  use sin, cos, tan

--  use the Law of Sines, the  Law of Cosines

It would be best if you gave specific problems, so we know what you need to know.

7 + 2(4x - 2) + 10

Do multiplication before you do add, so use the distributive property:

7 + 2(4x) - 2(2) + 10

7 + 8x - 4 + 10

Simplify by combining 7 - 4 + 10  =  3 + 10  =  13:

8x + 13      <---   answer

Im gonna guess 40 - 20 win for steelers!!! wooohooo! :D Go Steelers!

The probability of getting heads on any flip is (1/2)....this is the same probability of getting tails on any flip.

And the probability of getting 3 heads is (1/2)³......and he probability of getting tails on the rest of the flips is (1/2)¹⁵  ...... and we can choose any 3 of the 18 flips to have the heads occur....so we have

C(18,3)(1/2)³(1/2)¹⁵ =  about .0003 = about .03%

Because there are several items to consider:  the Pythagorean Theorem, sin, cos, and tan, 

it would be better if you gave us some specific problems.

In 45 minutes, Joseph would have written 1,920 words

There is more than one way to attack this problem.

One way is to, first, find how many words he types per minute:     1200 / 25  =  48 words per minute

And then:  at this rate for 45 minutes, he can type  48 x 45  =  2160 words.

What is the question?

In both degrees and radians, 10003sin(36) ≠ 1.33sin(02).

I'm going to assume that you mean completing a square in an algebraic equation.

Example:  2x² - 6x + 4  =  0

Step 1:  If the x² term has a coefficient other than 1, divide all terms by that number.

             Here the coefficient is 2, so divide all terms by 2:

             --->     x² - 3x + 2  =  0

Step 2:  Move the constant term to the other side:

             Here, subtract 2 from both sides:

             --->     x² - 3x          =  -2

Step 3:  Divide the coefficient of the x-term by 2, square that answer, and add that value to both sides:

             --->  -3 ÷ 2  =  -3/2                        (divide by 2)

             --->   (-3/2)²  =  9/4                       (square that answer)

             --->   x² - 3x + 9/4  =  -2 + 9/4       (add to both sides)

Step 4:  Simplify the constants:

            --->   x² - 3x + 9/4  =  1/4

Step 5:  Factor:

            --->  (x - 3/2)(x - 3/2)  =  1/4

            --->   (x - 3/2)²  =  1/4

Step 6:  Find the square root of both sides (don't forget the ± sign):

            --->   (x - 3/2)  =  ±√(1/4)

            --->   x - 3/2  =  ±1/2

            --->  x  =  3/2 ± 1/2

            --->   x  =  2  or  x  =  1

If this is the type of problem you had in mind, but don't understand some of the steps, please ask.

Each rotation of the wheel covers one circumference.

A circumference = 2·Π·r     --->     circumference  =   2·Π·30  =  60Π cm  ≈  188.49556 cm per circumference

How many circumferences are there in 41 radians?

     Since there are 2Π radians in one circumference,

             there will be 41 / (2Π) circumferences  ≈ 6.52535 circumferences

Putting this together, 6.52535 circumferences and each circumference ≈  188.49556 cm

     6.52535 x 188.49556 ≈  1230 cm

Thanks geno3141

If the ratios are 1:3:5, write them as:  1x, 3x, and 5x.

Since they are the three angles of a triangle, their sum is 180:   --->   1x + 3x + 5x  = 180°

--->   9x  =  180°

--->    x  =  20°

--->   x  =  20°     and     3x  =  60°     and     5x  =  100°

The quotient of a number and three is:  x/3

If  x/3  =  -4,  then multiply both sides by 3:

--->   x  =  -12

jewishnerd thats the formula for area of a triangle. Im not sure how this would answer the question. Please stop trolling the forums

The formula is Base*Hight/2     Your Welcome.
