Ziann’s weekly earnings were proportional to the number of hours she worked. This table shows the number of hours Susan worked and the amount she earned.
How much money did Ziann earn per hour?

Answers

Answer:

Can't answer.

Step-by-step explanation:

We know that Ziann's earnings were proportional to the hours she worked, but the table shows how much Susan earned, so we don't know how much Ziann earned. We are not told that Ziann and Susan are the same person.

Susan's earnings:

$47.50/(5 hours) = $9.50/hour

According to the table, Susan earned $9.50 per hour.

Please define the following terms:

mercantilism, import, export, enumerated article, legislature, indentured servant, Navigation Acts, Dominion of New England, English Bill of Rights.

Answers

Answer:

Mercantilism is an economic policy that is designed to maximize the exports and minimize the imports for an economy. It promotes imperialism, tariffs and subsidies on traded goods to achieve that goal

Import is to bring in (merchandise, commodities, workers, etc.) from a foreign country for use, sale, processing, reexport, or services.

Export is to ship (commodities) to other countries or places for sale, exchange, etc.

enumerated article is under the English navigation Acts, those commodities that could be shipped only to England or other English colonies; originally included sugar, tobacco, cotton, and indigo.

legislature is a deliberative body of persons, usually elective, who are empowered to make, change, or repeal the laws of a country or state; the branch of government having the power to make laws, as distinguished from the executive and judicial branches of government.

An indentured servant or indentured laborer is an employee (indenturee) within a system of unfree labor who is bound by a signed or forced contract (indenture) to work without pay for the owner of the indenture for a period of time

The Navigation Acts, or more broadly the Acts of Trade and Navigation, was a long series of English laws that developed, promoted, and regulated English ships, shipping, trade, and commerce between other countries and with its own colonies.

The Dominion of New England in America was an administrative union of English colonies covering New England and the Mid-Atlantic Colonies.

The English Bill of Rights was an act signed into law in 1689 by William III and Mary II, who became co-rulers in England after the overthrow of King James II. The bill outlined specific constitutional and civil rights and ultimately gave Parliament power over the monarchy

A Taxi cab costs $1.50 for the first mile and $0.75 for each additional mile. Which equation could be solved to find how many miles you can travel for $10, given that “x” is the number of additional miles? (Also solve this equation for the number of additional miles.)
A. 1.5x +0.75 = 10; x =6.17
B. 0.75x + 1.5 = 10; x = 11.333..
C. 1.5x -0.75 =10; x =7.17
D. 0.75x – 1.5 =10; x =15.33

Answers

Answer:

Step-by-step explanation:

I just used a calculator and did the math

it's b. 1.5 is the initial price for the first mile. then for each mile they add .75 meaning 1.5 + .75x = 10

A store sells a hoodie for $45, the sales tax rate in this state is 8%. What is the total price with sales tax applied?

Answers

The answer is $48.60.

The hoodie by itself has a price of $45. If the sales tax if 8% of the price you’d have to calculate the sales tax and add it to the net amount.

(45)(.08) = 3.60

(45) + 3.60 = 48.60

$48.60. multiply 45 by 0.08 to find the tax, which is $3.60. add the price plus the tax and you have the end price, which is $48.60
