1,279 * 4 + 3 = 5,019
Answer:
1662/10000
Step-by-step explanation:
Fine increase = 78 - 65 = 13
Increase rate = 13/65 x 100% = 20%
Discounted amount = 560 - 476 = 84
Discount rate = 84 / 560 x 100% = 15%
7 patties. 1/8 times 7 is 7/8
You can use a graphing calculator, or you can replace sin^2 by 1-cos^2 and solve the quadratic.
.. (1-cos^2) -cos^2 = 1 -cos
.. -2cos^2 = -cos
.. cos(2cos -1) = 0
The zero-product rule tells you
.. cos = 0 . . . . . . angle = π/2 +kπ
.. cos = 1/2 . . . . . angle = ±π/3 +2kπ
