In US usage, nickel is a five cent coin, struck by the United States Mint. It is composed of 75% copper, and 25% nickel, and is issued since 1866. It has a diameter of 21.21mm or 0.835 inch, and a thickness of 1.95mm or 0.077inch. To make a bunch of coins, tall 100 inches, we'll need 1299 coins, when it's the case, with five cents coins. Quarter, for example, has different dimensions, as well as thickness, so the number of coins will be different.

The number of nickels coins that are needed to made a stack of 100 inches tall is \boxed{1299}.

Further explanation:

Given:

The stack of nickels is 100 inches tall.

Explanation:

\boxed{1{\text{ dime}} = \$ 0.10}.

\boxed{1{\text{ dime}} = \$ 0.10}.

\boxed{1{\text{ quarter}} = \$ 0.25}.

A nickel is 5 cents.

The nickel is a cylindrical shape coin.

The thickness or height of the nickel coin is 0.077{\text{ inch}}.

The diameter of the nickel coin is 0.835{\text{ inch}}.

The radius of the nickel coin can be obtained as follows,

\begin{aligned}{\text{Radius}} &= \frac{{0.835}}{2}\\&= 0.4175{\text{ inches}} \\\end{aligned}

The number of nickels coins that are needed to made a stack of 100 inches tall can be obtained as follows,

\begin{aligned}{\text{Number of coins}} \times {\text{thickness of coin}} &= 100{\text{ inches}} \\n\times 0.077 &= 100\\n&= \frac{{100}}{{0.077}} \\n&= 1298.70\\n &= 1299\left( {{\text{approximately}}} \right) \\\end{aligned}

The number of nickels coins that are needed to made a stack of 100 inches tall is \boxed{1299}.

How did the British victory in the French and Indian War lead to the American Revolution?
victus00 [196]

Answer:

<h2>d. British debt after the French and Indian War led to increased taxation in the colonies.</h2>

Explanation:

The Seven Years War was fought in Europe from 1756-63.  That conflict as it extended to colonial territories in the New World was known as the French and Indian War.  The war had cost the British treasury 70 million pounds, which doubled their national debt.  The British felt they were entitled to tax the colonies for military protection against Indian tribes.

We might also note that France's loss in that war played a role in the American Revolution too.  Losing the conflict in North America to the British didn’t sit well with France. So, when the colonial Americans broke out in revolution against the British monarchy (in large measure about the taxation issue), France devoted enormous financial aid (as well as officer support) to the Americans. The cost to France for supporting America’s revolution added up to 1 billion livres  (about 4 billion in today’s dollars).
