Answer:
Thus, n = 4 is the solution.
Step-by-step explanation:
1. perform the indicated multiplication, obtaining 3n + 24 = 36
2. Subtract 24 from both sides: 3n = 12
3. Solve this result for n: n = 12/3. Thus, n = 4 is the solution.
X is how much it costs for one hour, so when you multiply it by 3 1/2, you get the amount of money charged for 3 and a half hours.
Answer:
the interest earned amount is $1,114.251
Step-by-step explanation:
The computation of the interest earned is shown below:
But before that the future value is
= Present value × (1 + rate of interest)^number of years
= $7,250 × (1 + 0.10)^1.5
= $7,250 × 1.10^1.5
= $8,634.251
Now the interets earned is
= $8,634.251 - $7,250
= $1,114.251
Hence, the interest earned amount is $1,114.251
Answer:
? = 10
Step-by-step explanation:
Let " ? " be x.
5 / x = x / 20
x * x = 5 * 20
x² = 100
[ 100 = 10 x 10 = 10² ]
x² = 10²
x = 10
