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.

Answer 1

Answer:

Answer: B

Step-by-step explanation:

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

Answer 2

Answer:

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

A sociologists was investigating the ages of grandparents of high school students. From a random sample of 10high school students, the sociologist collected data on the current ages, in years, of the students' maternal grandparents. A. One of the sociologist's research questions was about the mean difference in age without regard to which grandparent is older. The interval constructed in part (a) does not address such a question. Based on the sample of high school students, give the value of the point estimate for the mean difference in age that could be used to address the sociologist's question.

Simplify the following expression. 4a^-2b

A.) b/4a^2
B.)4b/a^2
C.)1/4a^b2

Answers

ANSWER

The correct answer is B

$\frac{4b}{ {a}^(2) }$

EXPLANATION

The given exponential expression is

$4 {a}^( - 2) b$

We can rewrite this as,

$4b * {a}^( - 2)$

We need to simplify to obtain a positive index, so we apply the following property,

${a}^( - m) = \frac{1}{ {a}^(m) }$

This implies that,

$4b * {a}^( - 2) = 4b * \frac{1}{ {a}^(2) }$

This will finally simplify to,

$4b * {a}^( - 2) =\frac{4b}{ {a}^(2) }$

Therefore the correct answer is B

the measures of an exterior angle and the adjacent interior angle add p to 360 because they form a linear plane?

Answers

Sadly, I can't see the picture you're looking at as you make that statement.
But I'm pretty sure that when you combine an exterior angle with the interior
angle adjacent to it, you'll wind up with 180°, because they form a linear line.
There actually isn't any such thing as a linear plane.

Is 7 weeks less or greater than 52 days

Answers

Hey there! :) So 7 weeks = 49 days, right? In order to get 49, you do 7(weeks) x 7(days per week) and get 49. Now, we compare. 49 < 52. 52 is greater.

Hope it helps! :D Have a great evening!

What is a Quadratic Equation?

In algebra, a quadratic equation is any equation that can be rearranged in a standard form where x represents an unknown, and a, b, and c represent known numbers, where a ≠ zero.

Conclusion: If a = zero, then the equation is linear, no longer quadratic, as there's no ax^2 term.

9 $x^(2)$ +12x+4=0
