This would be 6.05 * 10^7. I explained the cocnept of scientific notation in a different answer

8200 would be 8.2 * 10^3 in scientific notation

No, this number is not written in scientific notation.

Proper scientific notation is "a * 10^b" where "a" is a number between 1 and 10 and "b" is an exponent.

This basically means that "a" will be multiplied by 10 "b" times. When something is multiplied by 10 to a certain power (exponent), the value of the exponent is the number of places the decimal point will move. Positive exponents move the decimal point to the right, negative exponents move it to the left. If there are no more numbers to move the point, a zero is put in place of the number.

Examples:

5.6 * 10^4 = 56000.=56000  the point moved right four places because the ten was to the fourth power.

3.1 * 10^-7= .00000031 = 0.00000031 the point moved 7 places to the left because the ten was to the negative seventh power

Out of a deck of cards (which always has 52 cards) there are four suits, so 1/4 of all the cards will be of the suit spades. 1/4 of 52 is 13 cards. The thirteen cards will be numerical cards from 2-10 and the face cards (King, Queen, Jack and Ace). So the cards that would be a spade greater than 2 and less than 9 (non-inclusive) would be these six cards: 3,4,5,6,7 and 8. The odds of drawing one of those cards would be 6/52 or 3/26 when you simplify. The odds against drawing one of those six would be 46/52 or 23/26 when simplified. Hope this is helpful!

It sounds like on the opposite sides of a straight line are three angles, one lone angle (180 degrees) on one side and two angles (supplementary angles that together equal 180 degrees) on the other. So if one of the angles is 140 degrees then you can find the other angle by subtracting from 180:

180-140=40

angle A is 40 degrees
