Answer: 3.4 h
Explanation:
1) The basis to solve this kind of problems is that the speed of working together is equal to the sum of the individual speeds.
This is: speed of doing the project together = speed of Cody working alone + speed of Kaitlyin working alone.
2) Speed of Cody
Cody can complete the project in 8 hours => 1 project / 8 h
3) Speed of Kaitlyn
Kaitlyn can complete the project in 6 houres => 1 project / 6 h
4) Speed working together:
1 / 8 + 1 / 6 = [6 + 8] / (6*8 = 14 / 48 = 7 / 24
7/24 is the velocity or working together meaning that they can complete 7 projects in 24 hours.
Then, the time to complete the entire project is the inverse: 24 hours / 7 projects ≈ 3.4 hours / project.Meaning 3.4 hours to complete the project.
Answer:
i think the question is incomplete but
Tina at an average contains each package of
50 sheets ÷ 8 pack
6.205 of sheet in each pack
125 sheets ÷ 3 packs
caz contain at average 41.60 sheet average
but where the juan packs of paper that's why question is incomplete
Use x as the base variable. All others as x+(extra amount).
Answer:
nominal rate of interest is 31.7 %
Step-by-step explanation:
given data
payment = $1000
time = 2 year
rate = 4%
CPI = 100
CPI final yer = 127.7
to find out
nominal rate of interest
solution
we know nominal rate of interest formula that is
nominal rate of interest = real interest rate + inflation rate .........1
so here inflation rate is express as
inflation rate = ( CPI final year - CPI ) / CPI × 100 ...........2
put here value
inflation rate = ( 127.7 - 100 ) / 100 × 100
inflation rate is 27.7 %
so from equation 1
nominal rate of interest = real interest rate + inflation rate
nominal rate of interest = 4% + 27.7%
nominal rate of interest is 31.7 %
