Answer:
0.09
Step-by-step explanation:
Divide 1.25 by 5 which is 0.25, and 2.04 by 6 which is 0.34
Then subtract the answers 0.34-0.25=0.09
Answer:
12. $65.90, 13. 36.04cm
Step-by-step explanation:
12. the circumference of the circle is 2pi*r. lets say x is the circumference so x = 2*pi*3.8 = 23.876m. multiply x by 2.76 to get 65.898, round to get 65.90
13. the area of a circle is pi*r^2. the area of the pizza is 12*85=1020cm^2. divide by pi to get 324.676 cm^2. then find the square root to get r=18.019 cm. the diameter = 2r so multiply by 2 to get 36.038cm. I'm not sure what the problem wants to round to so you can round it yourself.
note: for these two problems i used the full pi instead of 3.14. using 3.14 will give you a different answer so it just depends. If the problem wants you to use 3.14, simply resolve the problems and use 3.14 instead of pi wherever required.
It should be k= 4 or -1/3
Answer: The required average is $576.
Step-by-step explanation:
Since we have given that
Percent of customers not returning each year = 25%
Average customer lifetime =
Percent of margin on the average bill = 60%
Cost per visit = $12
Number of times each year visited = 20 times
So, Average expense by each customer per year =
Average margin = 60% of 240 =
Average non discounted gross profit during a customer's lifetime is given by
Hence, the required average is $576.
