B) it will cost about the same to keep the movie or to return it; she should keep it.
5 days' worth of late fees would be 5(1.50) = 7.50.
The purchase price is 9.99; 9.99+7.50 = 17.49.
If she gets a cab, she pays around $10 round trip; 10 + 7.50 = 17.50
It is roughly the same price.
Answer:
x = -1/9
Step-by-step explanation:
first let's think of x as 1x so than x^2 is basically 1x.
you bring down 8x + 1 = 0 so you have x + 8x + 1 = 0.
than you add x and 8x which equals 9x.
you bring the problem down one more time so 9x + 1 = 0.
you subtract 1 from each side so the 0 becomes because 0 - 1 is -1.
So than you bring the rest of the problem down 9x = -1
Last thing you do is divide 9 from both sides which x = -1/9.
Use the sine rule:-
x / sin 48 = 4590 / sin (180-48-55)
x / sin 48 = 4590 / sin 103
x = 4590 * sin 48 / sin 103 = 3500.8 yards to nearest tenth
You divide the numerator by the denominator, so 2 divided by 5. That gets you 0.4 which is your answer.
