The equation is 500<7.50<950
then you solve for x
then you get 66.66<x< 126.66
this means that to make $500 you need to work at least 66.66 hours and to make $950 you need to work for at least 126.66 hours
Step-by-step explanation:
x=√7+√5, y=√7-√5
therefore, xy = (√7+√5)(√7-√5) = 7-5 = 2.
Hope this helps you.
Answer:
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.

Answer:
Time taken = 9987.38 years
Step-by-step explanation:
We have plutonium-240 decays according to the parent function
k is the decay constant,0.00011
k = 0.00011
We need to find how long will it take 27 grams of plutonium-240 to decay to 9 grams.
Q(t) = 9 g
Q₀ = 27 g
Substituting
Time taken = 9987.38 years
