Answer:
The least amount of numbers that he can work at his job to have enough for the headphones he wants is 17 hours.
Step-by-step explanation:
To find the number of hours you could divide the cost of the headphones by the amount he earns each hour so you would do $119/ 7 to get 17 and then you could check your answer with multiplication by multiplying 7 * 17 to get 119 which shows that he has to work at least 17 hours to get the headphones he wants.
$119 / 7 = 17
17 * 7 = 119
We have been given that a person places $6340 in an investment account earning an annual rate of 8.4%, compounded continuously. We are asked to find amount of money in the account after 2 years.
We will use continuous compounding formula to solve our given problem as:
, where
A = Final amount after t years,
P = Principal initially invested,
e = base of a natural logarithm,
r = Rate of interest in decimal form.
Upon substituting our given values in above formula, we will get:
Upon rounding to nearest cent, we will get:
Therefore, an amount of $7499.82 will be in account after 2 years.

Answer:
9/4
Step-by-step explanation:
1 2/7=9/7
2 1/3=7/3
--------------
9/7+7/3x+3/14+x=9
18/14+3/14+7/3x+3/3x=9
21/14+10/3x=9
10/3x=9-21/14
10/3x=9-3/2
10/3x=18/2-3/2
10/3x=15/2
x=(15/2)/(10/3)
x=(15/2)(3/10)
x=45/20
simplify
x=9/4
