1.08200000 x 10^8

5 -1948 Reference

 57, 909, 000

Put a decimal after the 5 and then write 7909

So we have

5.7909

Now....multiply this by 10 raised to the number of decimal places we moved the number to the left in the original number = 7

5.7909 x 10⁷

Oops...I mis-read this...... it was supposed to be    $b$/ $a$   ...!!!

Let  me revise my answer as

17, 576,000 / 260,000  = 67.6

I can't see any picture, but, based on the description, we have

V = pi  * r^2 * [(1/3) r - x] ...... where the last term in the brackets is the height

$${\frac{{\mathtt{3\,562}}}{{\mathtt{9}}}}$$ - If you want to leave it in am umproper fraction form

or

395.77778 (.7 repeating) - If you want to leave it in decimal

turn the % into a decimal. then multiply.

$${\mathtt{0.045}}{\mathtt{\,\times\,}}{\mathtt{10\,000}} = {\mathtt{450}}$$

0.75

First you need to figure out how to say the number in english. 0.75 is spoken in english is: "seventy-five one-hundredths" (2 places to the right of the decimal point is the hundreds place) 

Turn what you said into a fraction; original number on top, the placevalue on bottom. $${\frac{{\mathtt{75}}}{{\mathtt{100}}}}$$ Now you need to reduce the fraction.$${\frac{{\mathtt{75}}}{{\mathtt{100}}}} = {\frac{{\mathtt{3}}}{{\mathtt{4}}}}$$. this can be tricky if you don't know your times tables. this one was done by deviding both the top and bottom by the same number, 25 in this case... you could divide by 5, and then 5 again.$${\frac{{\mathtt{75}}}{{\mathtt{100}}}} = {\frac{{\mathtt{15}}}{{\mathtt{20}}}} = {\frac{{\mathtt{3}}}{{\mathtt{4}}}}$$

Another example: 0.125 = one hundred twenty-five thousands =$${\frac{{\mathtt{125}}}{{\mathtt{1\,000}}}} = {\frac{{\mathtt{1}}}{{\mathtt{8}}}}$$ ($${\frac{{\mathtt{125}}}{{\mathtt{1\,000}}}} = {\frac{{\mathtt{25}}}{{\mathtt{200}}}} = {\frac{{\mathtt{5}}}{{\mathtt{40}}}} = {\frac{{\mathtt{1}}}{{\mathtt{8}}}}$$ divide by 5 three times)

the answer is probably 7 just kidding its 3  hahaha lol maybe its 4

I looked at the answer to this question. I believe that everything is correct, except for the last step: I believe that the answer is 17,576,000 / 260,000 ...

A formula that can be used to find the sum of the interior angles of a polygon (regular or non-regular) is

                (n - 2)(180°)

where n is the number of sides. 

An octagon has 8 sides.

$${\mathtt{c}} = {\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{d}}$$

c= circumference (distance around a circle)

$${\mathtt{\pi}}$$= about 3.14 (um... it just "is" - to keep it simple)

d=diameter ($${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{r}}$$) (distance across the circle, through the center)

r=radius (distance from the center to the edge of a circle)

swapping d for r (and re-arranging) gets: $${\mathtt{c}} = {\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{\pi}}{\mathtt{\,\times\,}}{\mathtt{r}}$$

The answer is 4

$${\frac{\left({\left({\mathtt{1.5}}{\mathtt{\,\times\,}}{\mathtt{10}}\right)}^{{\mathtt{25}}}\right)}{\left({\mathtt{6.02}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{23}}}\right)}} = {\mathtt{419\,454.622\: \!824\: \!623\: \!735\: \!244\: \!1}}$$, Hopefully, this is what you meant.  I have NO IDEA what order of operation you were talking about.

Well, because 1/3 is 0.33... , then 2/3 is 0.66... ,So you would have the fraction be 13 2/3. 

Answer: 13 2/3

$$\frac{\left( 6-\left( -4 \right) \right)}{\left( 6-8 \right)}$$ = -5

Explanation:

x₂-x₁/y₂-y₁

 To be exact:$${\mathtt{22\,521\,008\,071\,930\,811\,247\,210\,364\,724\,710\,555\,878\,336\,746\,262\,578\,603\,045\,969\,925\,706\,618\,268\,298\,469\,415\,658\,031\,134\,405\,487.242\: \!341\: \!214\: \!456\: \!877\: \!8}} \approx {\mathtt{2.2521008071930811\times 10^{94}}}$$

7sinx=4

Sinx=4/7

X=asin(4/7)

answers will be in 1st and 2nd quadrants

-2$$\frac{1}{4}$$ = -2.25

explanation:

$$\frac{1}{4}$$ * 25 = $$\frac{25}{100}$$

You should recognize this as the difference of squares....

Take the square root of both terms ... 3x  and 4

Write these separated by a plus and then again separated by a minus, thusly :

(3x + 4 ) (3x -4)

That's it.....!!!

who knows?!?!!?!!???!??!??!!?!??!???????????????????????????

576 / 72    will give you your answer....
