Step-by-step explanation:
What is the molar mass of an element?
the total number of particles in one gram of the element
the mass of 6.02 x 1023 representative particles of the element
the number of amus (atomic mass units) in 6.02 x 1023 moles of the element
1.0 gram divided by the atomic weight of the element
Given:
hourly rate = 11.50
hours worked in a week = 40 hours
taxes per moth = 60
Every month may be 4 weeks or 5 weeks but we know that 1 year has 52.1429 weeks.
Let us compute for the whole year:
Earnings:
11.50 /1 hour * 40 hours/1week * 52.1429 weeks/1year
= 11.50 * 40 * 52.1429/year
= 23,985.734 per year
Taxes:
60 / per month * 12 months / 1 year
= 60 * 12/year
= 720 per year
Net earning per year
23,985.734 - 720 = 23,264.734
Net earning per month
23,264.734 ÷ 12 months = 1,938.81
You will earn 23,264.73 annually from a monthly earning of 1,938.81
Answer:
a is greater than or equal to 140
Step-by-step explanation:
Multiply both sides by 7, which cancels out the 7 and turns 20 into 140
Let 
be the two numbers. We have two pieces of information:
(the difference between the two numbers is 2)
(their product is 224)
From the first equation, we can deduce 
If we plug this expression in the second equation, we have
If you solve this equation with the usual quadratic formula you get the solutions
So, you have the following couple of solutions, recalling that x is 2 more than y:
