A certain brand of coffee comes in two sizes. An 11.5-ounce package costs 3.19. A 30.6-ounce package costs 7.98. Find the unit price for each size. Then state which size is the better buy based on the unit price. Round your answers to the nearest cent.
Answers
The size that is the better one is 30.6-ounce package costs 7.98.
How to calculate the cost?The 11.5-ounce package costs 3.19. The price per package will be:
= 3.19 / 11.5
= 0.27
A 30.6-ounce package costs 7.98. The cost per package will be:
= 7.98 / 30.6
= 0.26
In this case, it should be noted that the cheaper one.is the better buy. This was illustrated as the 30.6-ounce package costs 7.98.

Show that there exist a rational number a and an irrational number b such that a^b is irrational.
Answers
Answer:
In explanation below.
Step-by-step explanation:
Presumably, the proof you have in mind is to use a=b=2–√a=b=2 if 2–√2√22 is rational, and otherwise use a=2–√2√a=22 and b=2–√b=2. The non-constructivity here is that, unless you know some deeper number theory than just irrationality of 2–√2, you won't know which of the two cases in the proof actually occurs, so you won't be able to give aa explicitly, say by writing a decimal approximation.
g if you randomly select 850 credit card users, what interval will contain the sample proportion for 95% of samples of that size?
Answers
The Confidence interval is (0.85,1.05) which contain the sample proportion for 95%of samples size.
Confidence interval is an interval with a confidence level. Confidence interval is always constructed on basis of sample , p = sample statistic - margin of error to sample statistic + margin of error
Confidence interval for a proportion are calculated using the following formula:
p= ( p' - Z√p'(1-q')/n , p'+ Z √p'(1-p')/n ) ---(1)
where, p' ---> sample proportion for sucess
1-p' -----> sample proportion for failure
Z --> Z-value (statistic value)
n---> sample size
we have given that,
sample size ( n)=850 , sample proportion (p') = 0.95 and population proportion= 0.75
a) mean of sample of proportion is same as poplution proportion i.e 0.75 ..
1 -p' = q' = 0.05
Using the formula for margin of error ,
M .E = Z √ p'q'/n ---(2)
as the Z-value for given proportion is 13.46
putting all values in equation( 2) we get,
M.E = 13.45 √0.95×0.05/850 = 0.1005
Now, we shall calculate the confidence interval for given data
confidence interval (p)
= ( 0.95 - 0.100 , 0.95 + 0.100)
p= ( 0.85 , 1.05)
Hence,confidence interval(CI) is (0.85, 1.05).

Relative to ground level, what is the elevation of the hole after placing the bush in the hole?
Enter your answer as a simplified fraction. NOT MIXED NUMBER
Answers
The elevation of the hole after placing the bush in the hole is 17/8 feet
How calculate the elevation of the hole after placing the bush in the hole?
Given: Davis digs a hole at a rate of 3/4 feet every 10 minutes
After digging for 40 minutes, Davis places a bush in the hole that fills exactly 7/8 feet of the hole
This involves subtraction and multiplication of fractions
Since the rate of digging = 3/4 feet every 10 minutes
Thus, after digging for 40 minutes, the depth will be:
3/4 × 4 = 3 feet
If Davis places a bush in the hole that fills exactly 7/8 feet of the hole, the remaining depth or elevation will be:
3 feet - 7/8 feet = 17/8 feet
Therefore, after placing the bush in the hole, the elevation of the hole is 17/8 feet

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides. Look at the triangle ABC, where BC² = AB² + AC² is present. The base is represented by AB, the altitude by AC, and the hypotenuse by BC in this equation.
The distance between the courthouse and the library is 12 kilometres and the distance between the courthouse and the city pool is 13 kilometres. Let the distance between the library and the community pool be x and it can be observed that the Courthouse, library and Community hall form a sort of right-angled triangle
So, using Pythagoras theorem, we get
[tex]13^2=x^2+12^2\\x^2=169-144\\x^2=25\\x=5 km[/tex]
So, the library is 5 kilometres far from the community pool.

Two rectangular walls need to be painted. They are each 12 feet high and 23 feet
wide. It costs $1.50 per square foot for paint. How much will it cost to paint the
walls?
Answers
The amount that it will cost to paint the walls, given the cost per square foot and the dimensions of the rectangular walls is $828
How to find the cost?First, find the area of the rectangular walls by the formula for the area of a rectangle which is:
= Length x Width
The area of the rectangles is therefore:
= 12 x 23
= 276 feet ²
The area of the two rectangular walls is:
= 276 + 276
= 552 feet ²
The cost to paint the walls is:
= Area of walls x cost per square feet to paint

If there are 6 oz. left, and Sasha drank 1/3 of half the bottle, then that means she drank 3 oz, since 6 is 2/3 of 9, which means that half of the bottle was 9 oz. 9 oz. is half of 18 oz, which means that there were 18 ounces in the full bottle.
a fruit basket contains apples, oranges, and tangerines in the ratio 3:2:5, respectively. what is the total number of apples, oranges, and tangerines in the fruit basket?
Answers
The total number of apples, oranges, and tangerines in the fruit basket is in the ratio 10 or 10x
In mathematics, a ratio is a comparison of two or more numbers that indicates their sizes in relation to each other.
A ratio compares two quantities by division, with the dividend or number being divided termed the antecedent and the divisor or number that is dividing termed the consequent.
We know that : the ratio of apples : oranges : tangerines = 3 : 2 : 5.
The total number of apples, oranges, and tangerines in the fruit basket is the total number of ratio, that is 3 + 2 + 5 = 10.
Because of the question is not contain information about the number of pieces, we can describe the dividend with x (or unknown value). So, the total number of apples, oranges, and tangerines in the fruit basket with ratio, that is 10 or 10x.

The value of all the missing angles is in the measure of m∠1 = 88°, m∠2 = 42°, and m∠3 = 113°.
We know that,
Sum of all angles of triangle = 180°.
Therefore, m∠3 + 42° + 25° = 180°.
m∠3 = 180° - 67°
m∠3 = 113°
Vertical angles: Vertical angles are the angles that are opposite to each other when two lines cross.
We know that,
Vertical or opposite angles have equal measures.
So, 42° and m∠2 are vertical or opposite angles.
Therefore, the value of m∠2 = 42°.
Similarly, for m∠3, We know that,
Sum of all angles of triangle = 180°.
∴ ∠1 + ∠2 + 50° = 180°.

Find the value of the variables in the figure. Explain your reasoning.
Answers
The value of the variables in the figure is x = 60 degrees and y = 10 degrees.
From the figure:
x + 120 = 180 (since consecutive interior angles equal to 180)
x = 180 - 120
x = 60 degrees.
3y + 40 + 3x - 70 = 180(since supplementary angles = 180)
3y + 3x - 30 = 180
3(y + x) = 180 + 30
y + x = 210/3
y + x = 70
substitute x value
y + 60 = 70
y = 70 - 60
y = 10 degrees.
Therefore the value of the variables in the figure is x = 60 degrees and y = 10 degrees.

Jacob reduced the size of a painting to a width of 3. 2 inches. What would be the new height if the painting was originally 42. 88 inches in width and 33. 5 inches tall?.
Answers
The new height of painting by Jacob will be 2.5 inches.
The ratio and proportion will be used to relate the original and reduced dimensions of painting. The original width and height = 42.88/33.5. Let us assume the new height be x. So, new width and height = 3.2/x. Equating these two fractions -
42.88/33.5 = 3.2/x
Rewriting the equation according to x
x = (3.2 × 33.5) ÷ 42.88
Performing multiplication in numerator
x = 107.2 ÷ 42.88
Performing division on Right Hand Side of the equation
x = 2.5
