Basically, every zero a number has to the end, the higher the scientific notation will be. Because 1000 has three zeroes, 10^5 will go to 10^8. So, you will travel 7.5 x 10^8 miles.
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
640/79=8...8
79 goes through 640 8 times
(1/2)(3/6)=1/4
The probability of rolling a head (or tail for that matter is 1/2)
The probability of rolling less than 4 with a die is 3/6)
Thus the probability of both occurring is 1/4
<span>C/9 - 8 = 17
------------
Simplify
1/9c - 8 = 17
----------------
Add 8 to each side
1/9c - 8 + 8</span><span> </span><span>= 17 + 8
1/9c = 25
--------------------
Multiply each side by 9
9 * 1/9c = 9 * 25
c = 225</span>
