Please help will give brainliest!CheapBuys, a large bulk store, sells cases of bottled water for $13.49. There are 48 bottles in each case and the bottles are 12 ounces each. Sarah remembers that the vending machine at work sells the same size bottle for $0.75 per bottle. Calculate the cost for one bottle and tell if Sarah should buy bottled water by the case or not.

A: Buying in bulk will not save her any money since the bottles in the case and the bottles from the vending machine are both about 75 cents each.

B: The cost per bottle at CheapBuys is approximately 28 cents, so Sarah will save a considerable amount of money by buying water in bulk rather than from the vending machine.

C: Each bottle of water in the case from CheapBuys is 35 cents, so she should buy the case instead of buying it at work.

D: The case of water is $13.49. Since the individual bottles are cheaper in the vending machine, Sarah should buy the bottles at work.

Answers

Answer: B

Step-by-step explanation:

$13.49 ÷ 48 = $0.28  per bottle in the case

Answer:

Step-by-step explanation:

Step 1:

Cost of 1 case of water with 48 bottles - $13.49

Step 2:

Calculate cost of 1 bottle of water - (Cost of 1 case)/(Number of bottles)

13.49/48 = $0.28

Answer: B

Find the angle measure that makes the statement true.

Sin 25° = Cos ____ °

Answers

Answer:

          sin 25° = cos 65°

Step-by-step explanation:

We have trigonometric result

                  sin θ = cos (90 -θ)

Here we asked to convert Sin 25°  in to cosine.

So,

          sin 25° = cos (90 -25) = cos 65°

          sin 25° = cos 65°
65. 

You simply have to put cos-1(sin(25))
