1 mole of any substance is approximately 6.022*10^23 atoms (Avogadro's number)
So
(4.90*10^31 atoms) * (1 mole / 6.022*10^23 atoms) = 8.14*10^7 moles
Answer:
y=mx+b
Step-by-step explanation:
y=mx+b
If you know the slope m , and y -intercept (0,b) of a line (the point where the line crosses the y -axis), you can write the equation of the line in slope-intercept form .
If Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded,then he will get $33 after 2 years.
Given that Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded.
We are required to find the amount of money that Daniel will get after 2 years.
Since the amount is not compounded so interest will be same in all years as if in the first year.
The interest will be 2*30*0.05=3
The total amount including interest=30+3
=$33
Hence if Daniel has $30 in a savings account that earns 5% annually and the interest is not compounded,then he will get $33 after 2 years.

You can tell if lines are perpendicular or not by seeing if meet in a right angle. A right angle is like a square, and the lines would have to be 90 degrees.
One example is when the two lines (horizontal and vertical) meet each other at the ends.
(You MUST make sure that they are directly horizontal and vertical. If not, they will either be acute or obtuse).
I hope this helped!
Answer:
2
x=40
Step-by-step explanation:
A triangle has 180 degrees and considering that triangle ABC is similar to DEF that means they have the same angle (A=D,B=E,C=F)
180=104 +36+x
180=140+x
180-140=x
40=×
