What is the main reason Dylan uses the word uses the word “lonesome” to describe Hattie Carroll’s death?
lawyer [4039]

The correct answer is B. No one stood up for her

The song primarily addresses the racism prevalent in our nation. Dylan highlights that the murderer was not penalized initially; he was released on the night of the homicide due to his wealth, and during the trial, he received only a six-month term instead of a meaningful punishment. Hattie Carroll was largely overlooked in this scenario.

For each store what is the ratio of the number of cans to the price? Super saver 12 pack 4 for $10, shop smart 24 pack 2 for $9,
tester [3938]

At Super Saver, 4 packs are priced at $10, which gives us 12 × 4 = 48 cans for ratio calculation. The ratio translates to 48 cans for $10, or 4.8 cans per dollar. For Shop Smart, similarly, 24 × 2 results in 48 cans priced at $9, creating a ratio of 48 cans for $9, or 5 1/3 cans per dollar. At Price Busters, 12 × 3 results in 36 cans for $9, translating to a cost of 3 cans per dollar. Overall, Shop Smart offers the best value per can, followed by Super Saver, and lastly Price Busters.

Translate to an algebraic expression n−1 increased by 110%
tester [3938]

Answer:

Part 1) The algebraic expression can be represented as 1.10(n-1)  or 1.10n-1.10

Part 2) The algebraic expression is represented as \frac{1.10}{n}

Step-by-step explanation:

Part 1) The expression (n-1) raised by 110%

Recognizing that

110%=110/100=1.10

thus,

The algebraic representation of (n-1) increased by 110% translates to 1.10 multiplied by (n-1).

1.10(n-1)

Expanded

1.10n-1.10

Part 2) The expression n^(-1) raised by 110%

<pGiven that

110%=110/100=1.10

therefore, the representation of n^(-1) increased by 110% becomes 1.10 multiplied by n^(-1).

Remember that

n^{-1}=\frac{1}{n}

thus,

1.10(n^{-1})=1.10\frac{1}{n}=\frac{1.10}{n}

jane lives 1 3/8 miles from the airport. She drove from her house to the airport and back 2 times. How far did Jane drive? Move
Leona [4187]

Response:

5\frac{1}{2}\ mi

Detailed explanation:

We are aware that

1\frac{3}{8}\ mi=\frac{1*8+3}{8}=\frac{11}{8}\ mi

She made the trip between her residence and the airport twice.

Therefore,

Multiply the distance from her house to the airport by 4.

(4)*\frac{11}{8}=\frac{11}{2}=5\frac{1}{2}\ mi
