Answer: 19,244 ft

Step-by-step explanation:

1. To solve this exercise you can apply the formula for calculate the distance between two points, which is:

d=\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}

2. Then:

d_{AB}=\sqrt{(6,000-1000)^{2}+(7,000-8,000)^{2}}=5,099.01

d_{AC}=\sqrt{(5,000-1000)^{2}+(1,000-8,000)^{2}}=8,062.25

d_{AC}=\sqrt{(5,000-6000)^{2}+(1,000-7,000)^{2}}=6,082.76ft

3. Add the distance obtained to calculate the perimeter of the triangle. Therefore, the fence needed to the nearest food is:

P=5,099.01ft+8,062.25ft+6,082.76ft=19,244.02ft=19,244ft

A soldier started patrolling around his camp at 22 30 . His patrol lasted 3 hours and 20 minutes .What time did his patrol end
baherus [9]

Answer:01 50 Hrs

Step-by-step explanation:

If the soldier started patrol at 2230 hrs and his petrol lasted for 3 hours and 20 minutes, that means he was on patrol for that time.

The time he finished was therefore:

= 2230 + 320

= 2550

At 24 you begin at 0:00am so:

= 2550 - 2400

= 150

Patrol ended at 0150 hrs

To win a trivia game, Nathan must score at least 75 points. Each correct answer is worth 2 1/2 points , and each incorrect answe
Dmitrij [34]

Answer:

He scored 79\frac{1}{2} points.

Step-by-step explanation:

Given:

Number of points for a correct answer = 2\frac{1}{2}

Number of points scored for an incorrect answer = -\frac{1}{4}

Therefore, for 35 correct answers, points scored = 35\times 2\frac{1}{2}=35\times \frac{5}{2}=\frac{175}{2}

Now, for 32 incorrect answers, points scored = 32\times -\frac{1}{4}=-\frac{32}{4}=-8

Therefore, net number of points scored by Nathan is:

\frac{175}{2}-8=\frac{175}{2}-\frac{16}{2}=\frac{175-16}{2}=\frac{159}{2}=79\frac{1}{2}

Therefore, Nathan scored 79\frac{1}{2} points.
