Answer:
3.456 rounded to the nearest tenth would be 3.5.
Step-by-step explanation:
To round we look at the next smallest place value (i.e. the number to the right of the place you're rounding to).
If the number to the right is 5 or larger, you increase the number you're rounding to by (+1).
If the number to the right is smaller than 5, you keep the number you're rounding to the same.

Answer:
$7.488 or $7.49 (rounded)
Step-by-step explanation:
In order to find the amount of money at the end of 4 years, you have the find the amount of money after one year. So, the first step is to multiply 6.24 by .05 to get the percent gained in one year. This is .312. Then, you multiply the amount from the first year by four, for the other years, and get 1.248. That is how much you will earn in four years. Now, to get the total of all the money in the bank account after four years, you add 1.248 to 6.24. This sums up to 7.488 which is your answer. Hope this helps :)
The formula is
A=p (1+r/k)^kt
3000=150 (1+0.025/12)^12t
Solve for t
3000/150=(1+0.025/12)^12t
Take the log
Log (3000/150)=12t×log (1+0.025/12)
12t=Log (3000/150)÷log (1+0.025/12)
T=[Log (3000/150)÷log (1+0.025/12)]÷12
T=(log(3,000÷150)÷log(1+0.025÷12))÷12
T=119.954 years
Answer:
c) M/40
Step-by-step explanation:
The share of each company was originally M/10. Now it is M/8. The increase is ...
M/8 -M/10 = M(1/8 -1/10) = M(10-8)/(10·8) = M/40
