Question:What percentage of the British regiment were casualties in this battle?

Solution:To find the percentage of casualties:

160/800 × 100 = 20%

So, 20% of the British regiment were casualties in this battle.

Problem #2: (French Fort Supplies Used)Scenario:A French fort started with 1,200 barrels of supplies at the beginning of the winter. By the end of the winter, 960 barrels had been used.

Question:What percentage of the total supplies were used by the end of the winter?

Solution:To find the percentage of supplies used:

960 / 1200 × 100 = 80%

So, 80% of the supplies were used by the end of the winter.

Number Theory:

Problem #1: Prime Soldiers in British BattalionScenario:A British battalion had 257 soldiers at the start of the campaign. The commander wanted to split the soldiers into equal groups for different tasks, but the number of soldiers seemed difficult to divide evenly.

Question:Is the number of soldiers in the battalion, 257, a prime number? If not, what are its divisors?

Solution:To determine if 257 is a prime number, we check if it has any divisors other than 1 and itself. After checking divisibility by prime numbers up to the square root of 257 (which is approximately 16), we find that 257 is not divisible by any primes.

Therefore, 257 is a prime number, and its only divisors are 1 and 257.

Problem #2: Greatest Common Divisor of Supply ShipmentsScenario:During the war, two French supply shipments to Fort Duquesne arrived with different numbers of barrels. The first shipment had 84 barrels, and the second had 126 barrels. The soldiers needed to divide the barrels into the largest equal groups possible, ensuring that each group received the same number of barrels from both shipments.

Question:What is the greatest number of barrels that each group can receive from both shipments?

Solution:To find the greatest number of barrels that can be equally divided, we need to find the greatest common divisor (GCD) of 84 and 126. The factors of 84 are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84, and the factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.

The greatest common divisor is 42.

Therefore, each group can receive up to 42 barrels from both shipments.

Geometry:

Problem #1: (Fort Layout Perimeter Calculation)Scenario:A British fort during the French and Indian War was designed as a rectangular structure with a length of 120 feet and a width of 80 feet. The soldiers needed to build a protective wall around the entire fort.

Question:What is the total perimeter of the fort that the soldiers need to cover with the wall?

Solution:The formula for the perimeter of a rectangle is:

P = 2 × (L + W)

Where L is the length and W is the width. Substituting the values:

P = 2 × (120 + 80) = 2 × 200 = 400 feet

The total perimeter of the fort is 400 feet.

Problem #2: (Area of a Circular Cannon Placement)Scenario:At a French fort, the soldiers placed a circular cannon platform with a diameter of 10 feet. They needed to know the area of the platform to ensure it was large enough to hold their equipment.

Question:What is the area of the circular cannon platform?

Solution:The formula for the area of a circle is:

A = πr2

First, find the radius by dividing the diameter by 2:

R = 10/2 = 5 feet

Now calculate the area:

A = π × 52 = π × 25 ≈ 3.14 × 25 = 78.5 square feet

The area of the circular cannon platform is approximately 78.5 square feet.

Trigonometry:

Problem #1: Height of a Flagpole at the FortScenario:At a British fort during the French and Indian War, a flagpole is mounted on top of the fort's wall. A soldier standing 50 feet away from the base of the flagpole measures the angle of elevation to the top of the flagpole as 30 degrees.

Question:What is the height of the flagpole?

Solution:We can use the tangent function, where:

tan(θ) = opposite/adjacent

In this case, the angle θ = 30∘ the adjacent side is 50 feet, and the opposite side is the height of the flagpole (let’s call it h).

tan(30∘) = h/50

Using tan(30∘) ≈ 0.577:

0.577 = h/50 ​

Solve for h:

h = 0.577 × 50 = 28.85 feet

The height of the flagpole is approximately 28.85 feet.

Problem #2: Distance Across a River for Troop CrossingScenario:A group of French soldiers needs to determine the width of a river to cross safely. They measure the angle of depression from a hill on one side of the river to the opposite bank at 45 degrees. The hill is 60 feet tall.

Question:What is the width of the river?

Solution:We can use the tangent function again, where the angle of depression is 45 degrees, and the height of the hill (opposite side) is 60 feet. Let d represent the width of the river (adjacent side).

tan(45∘) = 60d

Since tan(45∘) = 1, we have:

1=60/d

Solve for d:

d=60 feet

The width of the river is 60 feet.

Geometry:

Problem #1: (Area of Fortification Walls)Scenario: A French fort during the French and Indian War was designed in the shape of a square. Each side of the fort’s walls measured 150 feet. The commander wanted to know the total area enclosed by the fort’s walls to ensure they had enough space for supplies and soldiers.

Question: What is the total area enclosed by the fort’s walls?

Solution: The formula for the area of a square is:

A=s2 

Where s is the length of one side. Substituting the value:

A=1502=22,500 square feet

The total area enclosed by the fort’s walls is 22,500 square feet.

Problem #2: (Distance Between Two Watchtowers)Scenario: Two watchtowers were set up on opposite corners of a rectangular fort during the French and Indian War. The length of the fort was 180 feet, and the width was 120 feet. The commander wanted to know the diagonal distance between the two towers for communication purposes.

Question: What is the diagonal distance between the two watchtowers?

Solution: The diagonal distance in a rectangle can be found using the Pythagorean Theorem:

d2 = l2 + w2

Where l is the length, w is the width, and d is the diagonal. Substituting the values:

d2 = 1802 + 1202                                  d2 = 32,400 + 14,400 = 46,800

Now, take the square root of both sides:

d = 46,800 ≈ 216.33 feet

The diagonal distance between the two watchtowers is approximately 216.33 feet.

Algebra II:

Problem #1: (Logistic Planning for Troops)Scenario: A British general needed to organize supplies for his soldiers. The number of supply barrels required is modeled by the equation S=3n+50, where S is the total number of barrels and n is the number of soldiers. The general has 200 soldiers under his command.

Question: How many barrels of supplies are needed for 200 soldiers?

Solution: Substitute n = 200 into the equation S = 3n + 50:

S = 3(200) + 50 = 600 + 50 = 650

So, 650 barrels of supplies are needed for 200 soldiers.

Problem #2: (Exponential Growth of Troop Numbers)Scenario: A fort’s population of soldiers is expected to grow according to the equation P(t) = 500 × (1.05)t represents the number of soldiers after t months, and 500 is the initial number of soldiers stationed at the fort. The general wants to know how many soldiers will be stationed at the fort after 6 months.

Question: How many soldiers will be stationed at the fort after 6 months?

Solution: Substitute t = 6 into the equation P(t) = 500 × (1.05)t:

P(6) = 500 × (1.05)6

First, calculate (1.05) 6 ≈ 1.3401:

P(6) = 500 × 1.3401 = 670.05

Rounding to the nearest whole number, there will be approximately 670 soldiers stationed at the fort after 6 months.

Calculus:

Problem #1: (Maximizing Supply Efficiency)Scenario: A British fort receives supplies at a rate modeled by the function S(t) = −2t2 + 12t+100, where S(t) represents the amount of supplies (in barrels) received after t days. The general wants to know when the fort receives the maximum amount of supplies in a single day.

Question: At what time t does the fort receive the maximum amount of supplies, and how many supplies are received at that time?

Solution:To find the maximum amount of supplies, we need to find the critical points of S(t)S(t)S(t) by taking the derivative and setting it equal to zero:

S′(t) = d/dt (−2t2 + 12t + 100) = −4t + 12

Now, set S′(t)=0:

−4t + 12 = 0

T = 12/4 = 3

So, the maximum occurs at t=3 days. Now, substitute t=3 back into the original function to find the maximum amount of supplies:

S(3) = −2(3)2 + 12(3) + 100 = −18 + 36 + 100 = 118

The fort receives the maximum amount of 118 barrels on the 3rd day.

Problem #2: (Rate of Change of Troop Movement)Scenario: The distance traveled by a group of French soldiers marching to reinforce a fort is given by the function D(t) = t3 − 6t2 + 9t, where D(t) is the distance (in miles) after t hours. The general wants to know the rate of change of their movement at any given time.

Question: Find the rate of change of the soldiers' movement after 2 hours.

Solution:To find the rate of change of the distance traveled, we take the derivative of D(t):

D′(t)=d/dt (t3 − 6t2 + 9t) = 3t2 − 12t + 9

Now, substitute t=2 to find the rate of change after 2 hours:

D′(2) = 3(2)2 − 12(2) + 9 = 3(4) – 24 + 9 = 12 – 24 + 9 = −3 miles per hour

The rate of change of the soldiers' movement after 2 hours is −3 miles per hour, meaning they are slowing down.
