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.

Answer:
I think x is 34.75.
Step-by-step explanation:
Same side interior angles are supplementary to each other. Angle C and angle E are congruent to each other.

write the following sets in explicit form and determine the cardinality of
each set.
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 = 24Put the expressions in order from least to greatest value
Answers
Answer:
Least: [tex]\sqrt[6]{64}[/tex]
2nd least: ([tex]\sqrt{64}[/tex])²
2nd greatest: [tex]\sqrt{81}[/tex] · [tex]\sqrt{81}[/tex]
Greatest: 1/64^-2
Step-by-step explanation:
[tex]\sqrt[6]{64}[/tex] = 2
([tex]\sqrt{64}[/tex])² = 64
[tex]\sqrt{81}[/tex] · [tex]\sqrt{81}[/tex] = 9 · 9 = 81

At the not much fun amusement park, Otaka Shawa paid $25.75 for three game of mini-marbles-golf and two rides on the slow-go-karts,while Soren Derkeister paid $35.75 for four games of mini-marbles-golf and three rides on the slow-go-karts. How much did each activity cost?
Answers
3m + 2g = 25.75
4m + 3g = 35.75
We’ll take the top equation and solve for g in terms of m.
2g = -3m + 25.75
g = (-3m + 25.75)/2
Then substitute that mess, um, expression, I to the second equation to solve for m.
4m + 3[(-3m + 25.75)/2] = 35.75
4m + (-9m + 77.25)/2 = 35.75
4m -4.5m + 38.625 = 35.75
-0.5m = -2.875
0.5m = 2.875
m = 5.75
Now we pick an equation, plug in the numerical value of m, and solve for a numerical value of g
3m + 2g = 25.75
3(5.75) + 2g = 25.75
17.25 + 2g = 25.75
2g = 8.50
g = 4.25
Checking the math:
4m + 3g = 35.75
4(5.75) + 3(4.25) = 23 + 12.75 = 35.75
Mini marbles golf cost $4.25, slow go karts cost $5.75.
Find c. Round to the nearest tenth.
Answers
Answer:
Step-by-step explanation:
A = 150°
B = 12°
C = 180 - (150 + 12) = 18°
b = 10 cm
Apply the sine rule:
[tex] \frac{b}{sin(B)} = \frac{c}{sin(C)} [/tex]
Plug in the values
[tex] \frac{10}{sin(12)} = \frac{c}{sin(18)} [/tex]
Multiply both sides by sin(18)
[tex] \frac{10}{sin(12)}*sin(18) = \frac{c}{sin(18)}*sin(18) [/tex]
[tex] \frac{10*sin(18)}{sin(12)} = c [/tex]
c = 14.9 cm (nearest tenth)

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.

Answers
Answer:
13
Step-by-step explanation:
The velocity is given by:
[tex]\displaystyle v(t)= -2t + 8[/tex]
And the total distance given the velocity is given by:
[tex]\displaystyle \int_{a}^{b}|v(t)|\, dt[/tex]
So, the total distance traveled by the particle from t = 1 to t = 6 will be:
[tex]\displaystyle d=\int_{1}^{6}|-2t+8|\, dt[/tex]
The absolute value tells us that:
[tex]\displaystyle |-2t+8| = \left\{ \begin{array}{ll} -2t+8 & \quad x \leq 4 \\ -(-2t+8) & \quad x > 4\\ \end{array} \right[/tex]
So, split the integral into two parts:
[tex]\displaystyle d=\int_{1}^{4} (-2t+8)\, dt+\int_{4}^{6}(-(-2t+8))\, dt[/tex]
Integrate:
[tex]\displaystyle d=(-t^2+8t)\Big|_{1}^{4}+(t^2-8t)\Big|_{4}^{6}[/tex]
Evaluate:
[tex]\begin{aligned} d&=[(-4^2+8(4))-(-1^2+8)]+[(6^2-8(6))-(4^2-8(4)]\\ &= [16-7]+[-12-(-16)]\\ &=9+4 \\ &=13 \end{aligned}[/tex]

Demi has 221 songs on her phone. The songs take up 884 megabytes of storage . Each song takes up same amount of space . How many megabytes do 135 of these songs take up?
Answers
Answer:
540 megabytes
Step-by-step explanation:
We will first need to find out how much space a singular song will take up. We will do this by the storage taken up (884) by the number of songs she has:
884 / 221 = 4 mb taken up per song
Then we want to find out how many megabytes 135 of these songs take up, so we will multiply the mb taken up per song (4) by the number of songs we want to find (135):
4 x 135 = 540 megabytes

Abel saved 43 more nickels than dimes. After he spent 17 dimes he had twice as many nickels than dimes. How many coins did he have left?
Answers
Answer:
180 coins
Explanation:
N = number of nickels (no nickels spent)
D = number of dimes initially saved
D' = number of dimes left after spending
1) N = D + 43
2) D' = D - 17
3) N = 2*D' = 2*(D - 17)
Set equations 1) and 3) equal to each other and solve for D:
D + 43 = 2*(D - 17)
D + 43 = 2*D - 34
D = 43 + 34 = 77
N = D + 43 = 77 + 43 = 120 nickels left
D' = D - 17 = 77 - 17 = 60 dimes left
Total coins left = 120 + 60 = 180 coins (I hope this is not too confusing for you)
Number of nickels 120, number of dimes 60 and total number of coins 180.
Given that, Abel saved 43 more nickels than dimes. After he spent 17 dimes he had twice as many nickels than dimes.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let
N = number of nickels (no nickels spent)
D = number of dimes initially saved
D' = number of dimes left after spending
N = D + 43 ..........(1)
D' = D - 17 ..........(2)
N = 2×D' = 2×(D - 17) ..........(3)
Set equations (1) and (3) equal to each other and solve for D:
D + 43 = 2×(D - 17)
D + 43 = 2D - 34
D = 43 + 34 = 77
N = D + 43 = 77 + 43 = 120 nickels left
D' = D - 17 = 77 - 17 = 60 dimes left
Total coins left = 120 + 60 = 180 coins
Therefore, number of nickels 120, number of dimes 60 and total number of coins 180.
