The cost per ounce of the first bottle is $0.415 and the second bottle is $0.699.
The first bottle has the better deal because if you were to have 14 ounces of the first type of shampoo, it would only cost $5.81
Unfortunately I'm unable to understand
At a book fair, a tote bag cost $3.50 each. You spend a total of $19. How many did you buy in addition to one tote bag?6
When simplifying you need to be able to divide both the top and bottom number in the fraction by one of their factors. A number will be fully simplified when they become a prime number or have one as the numerator.
Answer:
Sine is equal to opposite over hypotenuse in right triangles. Let's say we have a 3-4-5 right triangle, the side opposite the 90° angle is 5, and 5 is also the hypotenuse. 5/5 = 1
Therefore, in all right triangles, the side opposite the 90° angle is equal to the hypotenuse, and anything over itself is equal to one.
(Not sure if this is a mathematically correct way to explain it, but it makes the most sense to me.)
