Which sentence is an example of an objective summary from Cynthia Crossen's "A Culinary Wasteland"?
A. Furthermore, Mr. Schlosser's appraisal is not comprehensive but a hodgepodge of impressions, statistics, anecdotes and prejudices.
B. As a stickler about statistics, I was disturbed by Mr. Schlosser's cavalier manipulation of data, which produced some startling — and, frankly, unbelievable — "facts."
C. Americans are addicted to cheap, bad food, he argues, and like all addictions, this one exacts broad and often unseen costs from the community.
D. Taking individual responsibility for one's impact on the global economy is far more complicated than just saying no to fast food, as Mr. Schlosser advises.

A rectangular garden has a width of 10 feet and a length of 14 feet. A cement walkway is added around the outside of the garden. The area of the garden and the walkway together are 320 square feet. What is the width of the walkway
Answers
Answer:
The width of the walkway is of 12.86 feet.
Step-by-step explanation:
Area of a rectangle:
The area of a rectangle of length l and width w is given by:
A = lw
A rectangular garden has a width of 10 feet and a length of 14 feet.
So the area of the rectangular garden is of 10*14 = 140 square feet.
The area of the garden and the walkway together are 320 square feet.
So the area of the walkaway is of 320 - 140 = 180 square feet.
What is the width of the walkway
It has the same length of the garden, of 14. So
[tex]14w = 180[/tex]
[tex]w = \frac{180}{14}[/tex]
[tex]w = 12.86[/tex]
The width of the walkway is of 12.86 feet.

1) x² + x + 3 = 0 use the discriminant to tell whether the equation has two solution
Answers
Answer:
The equation does not have any real solutions.
The equation only has two imaginary solutions.
Step-by-step explanation:
Step 1
Use Discriminant to check how many solutions does the equation have.[tex] \large{D = {b}^{2} - 4ac}[/tex]
Let a = 1, b = 1 and c = 3 from the given equation.
[tex]D = {(1)}^{2} - 4(1)(3) \\ D = 1 - 12 \\ D = - 11[/tex]
Since the value of D is in negative. Therefore, the equation does not have any solutions.
Discriminant

Answer: -pi/4 and 3pi/4
Step-by-step explanation:
Whenever you're given an inverse trig function like this, think "tangent of what gives me -1?" There are multiple ways in which you can solve this; knowing how tangent work, guess checking sin/cos to get -1, or using a calculator. The only way tangent can be an integer is if the sine and cosine of the angle are equal.

A force of 90 Newtons is applied to a 20 cm2 surface.
The force applied is then increased by 5 Newton’s and the surface area is increased by 5 cm^2
Answers
The given question is incomplete. The complete question is:
A force of 90 Newton's is applied to a [tex]20cm^2[/tex] surface. The force applied is then increased by 5 Newton's and the surface is increased by [tex]5cm^2[/tex]. What percentage does the outcome decrease by
Answer: The outcome decreases by 15.5 %
Step-by-step explanation:
Pressure is defined as the ratio of force per unit area.
[tex]Pressure=\frac{Force}{Area}[/tex]
Case 1: [tex]P_1=\frac{90N}{20cm^2}=4.5Ncm^{-2}[/tex]
Case 2: [tex]P_2=\frac{95N}{25cm^2}=3.8Ncm^{-2}[/tex]
Decrease in pressure = [tex]P_1-P_2[/tex] = [tex](4.5-3.8) Ncm^{-2}=0.7Ncm^{-2}[/tex]
Percentage decrease = [tex]\frac{0.7}{4.5}\times 100\%=15.5\%[/tex]
Thus the outcome decreases by 15.5 %

To make an international telephone call, you need the for the country you are calling. The codes for country A, country B, and C are three consecutive integers whose sum is 90. Find the code for each country.
Answers
Answer: 3 consecutive integers
x = 1st integer (country A)
x + 1 = 2nd integer (country B)
x + 2 = 3rd integer (country C)
whose sum is 114
x + (x + 1) + (x + 2) = 114...combine like terms
3x + 3 = 114
3x = 114 - 3
3x = 111
x = 111/3
x = 37 <== country A
x + 1 = 37 + 1 = 38 <==country B
x + 2 = 37 + 2 = 39 <== country C
Step-by-step explanation:
Answer:
29, 30, 31
Step-by-step explanation:
(x) + (x+1) + (x + 2) = 90
3x + 3 = 90
x = 29
(29) + (30) + (31) = 90

a) μ = {x: x is a positive counting number less 25}
Answers
Answer:
As the givens set μ has 24 elements.
Therefore,
Cardinality = 24Step-by-step explanation:
Given
μ = {x: x is a positive counting number less 25}
The set of natural numbers is often termed as the Counting number set.
As the counting numbers are less than 25.
Thus, the set μ is:
μ = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}
We know that cardinality of the set is the number of elements in a given set.
As the givens set μ has 24 elements.
Therefore,
Cardinality = 2412. Ryan deposited $3,500 in a savings account with
