Answer: a discount of 25%
Step-by-step explanation:
if you take any number and take 10 percent off then 15 percent off it’s even but 25 percent off is a better discount because it takes more money off the original price
Answer:
1.11
Step-by-step explanation:
If you know all the side lengths of a right triangle, you can use trigonometry ratios to find sines, cosines, and tangents.
sin(x) = opposite / hypotenuse
cos(x) = adjacent / hypotenuse
tan(x) = opposite / adjacent
If we are finding the tangent of angle X, we can see that the opposite side is 72 units and the adjacent side is 65 units.
Using the ratio, we can conclude that tan(x) = 72/65.
Use your calculator to divide, and you will get 1.10769, which is approximately 1.11.

5. is 19.53 Use the Pythagorean Theorem. The length of the ladder is the hypotenuse and 19 is the vertical side and the 4.5 is the horizontal side.
7. y= 20.4
I don't know the rest.
Answer:
b. y+10=-(x-3)
Step-by-step explanation:
<span>In this case, every bottle has 500 mg of caffeine with a standard deviation of 25 mg. The equation of a bottle will be: 500 +/- 25mg caffeine per bottle.
To calculate a carton containing 30 bottles, you just need the equation with 30. It will become: (500x30) +/- (25x30)mg= 15000 +/- 750 mg of caffeine per carton</span>
