3147.6 x 25 = 78690 and there’s one decimal place left so add the decimal place and it’s 7869.0 and the 0 doesn’t count so it’s 7869.
Answer:
$1,951.03.
Step-by-step explanation:
To determine how much money would you have to invest at 7% compounded semiannually so that the total investment has a value of $ 2,090 after one year, the following mathematical calculation must be performed:
X x (1 + 0.07 / 2) ^ 1x2 = 2,090
X x 1,035 ^ 2 = 2,090
X x 1.071225 = 2,090
X = 2,090 / 1.071225
X = 1,951.03
Thus, $ 1,951.03 must be invested at 7% per annum compounded semiannually to have $ 2,090 in the account after one year.
5/12 of students worked on homework, what you do is you first add up the total amount of students, which is 12. That becomes our denominator. Then, we already know that there are five students doing homework. That becomes our denominator. 5/12 also cannot be simplified because 5 is a prime number, so therefore, 5/12 is in simplist form.
