Answer:
a: 70 degrees, b: 140 degrees
Step-by-step explanation:
Each of the sets of angles must add up to 180 degrees.
180 - 110 = 70
180 - 40 = 140
Answer:
The doubling time of this investment would be 9.9 years.
Step-by-step explanation:
The appropriate equation for this compound interest is
A = Pe^(rt), where P is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
If P doubles, then A = 2P
Thus, 2P = Pe^(0.07t)
Dividing both sides by P results in 2 = e^(0.07t)
Take the natural log of both sides: ln 2 = 0.07t.
Then t = elapsed time = ln 2
--------- = 0.69315/0.07 = 9.9
0.07
The doubling time of this investment would be 9.9 years.
Answer:
The number of hours of work for first two weeks is 44 hours .
Step-by-step explanation:
Given as :
The money paid by company as per hour = $25 per hour
The hiring bonus money = $100
The total money paid for first two weeks = $1200
Let The number of hours of work for first two weeks = n
<u>According to question</u>
Total money paid for first two weeks = hiring bonus money + money paid by company as per hour × number of hours of work for first two weeks
i.e $1200 = $100 + $25 × n
Or, $1200 - $100 = $25 × n
Or, $1100 = $25 × n
∴ n = ![\dfrac{1100}{25}](https://tex.z-dn.net/?f=%5Cdfrac%7B1100%7D%7B25%7D)
i.e n = 44
So, The number of hours of work for first two weeks = n = 44 hours
Hence, The number of hours of work for first two weeks is 44 hours . Answer
