Answer: 
<u>Step-by-step explanation:</u>
1st marble and 2nd marble
<span>2.607 x 10^13 dollars per person.
Avogadro's number is approximately 6.0221409x10^23.
So divide by the 231 million people. Giving
(6.0221409 x 10^23) / (231 x 10^6) = 0.02607 x 10^17
= 2.607 x 10^15 pennies
But we want dollars, so divide by 100
2.607 x 10^15 / 100 = 2.607 x 10^13 dollars</span>

Step-by-step explanation:
Answer:
y = 2/3x - 1
Step-by-step explanation:
Find the slope:
2y = 3x - 5
2/2y = 3/2x - 5/2
y = 3/2x - 5/2
Slope is 3/2
In order for a line to be perpendicular the slope in the equation should be flipped. 3/2 becomes 2/3.
Perpendicular equation:
y = 2/3x + b
b is going to be equal to the y intercept of the point they gave us, so -1.
Answer: y = 2/3x - 1
