Answer:
$3.80 per book
Step-by-step explanation:
I divided 19 by 5 to get the price per book
$1.90 for each pendant
Can you please give me the brainliest answer? I am trying to get to the next rank, and my friend and I are competing :)
Your answer is correct. Indeed:
- In order to find the degrees per minute, you have to divide the full rotation angle (which is 360deg) by the number of minutes (which is 60):
360deg ÷ 60min = 6 deg/min
- In order to find how many minutes have passed, you subtract the times:
1h50m - 1h25m = 0h25m
- You then find how many degrees correspond to 25minutes:
6 deg/min × 25 min = 150deg
- Lastly, you transform degrees into radiants, through the proportion:
deg : 180 = rad : π
Therefore,
150 : 180 = rad : π
rad = (150×π)/180 = 5π/6
You make 2 2/7 an improper fraction (16/7) and then you subtract 8/7 from 16/7 and you get 1 1/7 (or 8/7) as your final answer
Answer:
no real solutions
complex solutions: x = 0.5±i√10.75, y = -2.5±i·3√10.75
Step-by-step explanation:
The graph shows the line and parabola do not intersect, so there are no real solutions to this system of equations.
__
However, the complex x-solutions can be determined from the graph to be ...
x = 0.5 ±i√10.75
The corresponding y-values can be found from the equation
y = 3x -4 = 3(0.5 ±i√10.75) -4
y = -2.5 ± i·3√10.75
