179° the process is shown in the following picture
Let the time at which the two friends are at the same distance be x. With this representation, the equation would be,
3x = 4(x - 5/60)
The value of x from the equation is 0.33, which has a units of hours. Since, we are in minutes.
minutes = (0.333)(60)
minutes = 20
Answer: 20 minutes
Answer:
8.25%
Step-by-step explanation:
First, we need to find the dollar amount of tax:
Original Price = 380
Price with tax = 411.35
Hence, Tax = 411.35 - 380 = $31.35
To find the % of tax, we divide the tax amount by the original amount. Then, multiply that answer by 100 to get the "percentage". The process is shown below:
Tax Percentage = Tax Amount/Original Amount * 100
Thus,
Tax Percentage =
Tax percentage = 8.25%
Answer:
1, 2, and ±i√8
Step-by-step explanation:
0 = x⁴ − 3x³ + 10x² − 24x + 16
Using grouping:
0 = x⁴ − 3x³ + 2x² + 8x² − 24x + 16
0 = x² (x² − 3x + 2) + 8 (x² − 3x + 2)
0 = (x² + 8) (x² − 3x + 2)
0 = (x² + 8) (x − 1) (x − 2)
The roots are 1, 2, and ±i√8.
