Five days a week, you carpool with 3 co-workers and take turns driving each week. It is 14 miles from your home to your office.

When you drive the carpool you must go an extra 4 miles to pick up your co-workers. If your car averages 18 miles per gallon, about how many gallons of gas should you save every 4 weeks by carpooling?

Answer:

Over four weeks of carpooling, I estimate saving 21.11 gallons of gas.

Detailed explanation:

If I drove to work alone daily, the total distance covered in four weeks would be: 2 × 14 miles × (4 weeks × 5 days) = 2 × 14 × 20 = 560 miles.

When carpooling with three colleagues, I only drive for one week out of every four.

This means during the week I drive, the total distance is: 2 × (14 miles + 4 miles extra for pickups) × 5 days = 2 × 18 × 5 = 180 miles.

Consequently, the miles driven less in four weeks equals 560 – 180 = 380 miles.

Given my car's fuel efficiency is 18 miles per gallon, the saved fuel over four weeks is 380 / 18 = 21.11 gallons.

zzz [12365]

Answer:

Aproximadamente 428 N

Step-by-step explanation:

Peso = 1,500 * 9.8 = 14,700 N

Densidad = Masa ÷ Volumen

1,030 = 1,500 ÷ V

V = 1,500 ÷ 1,030 = 1.46 m^3.

La fuerza de flotación = Densidad * g * V

La fuerza de flotación = 1,000 * 9.8 * (1,500 ÷ 1,030)

La fuerza de flotación = 9,800 * (1,500 ÷ 1,030) = 14,272 N.

La fuerza neta = 14,700 – [(9,800 * (1,500 ÷ 1,030)]

Each tweet could cost anywhere from 1 to 140 pennies, which can be expressed as an inequality [1 ≤ x ≤ 140]. Since it's impossible to tweet 0 characters or exceed 140. If required in pounds, simply divide by 100. A) 1 ≤ x ≤ 140 B) The cost per character is a penny, and tweeting fewer than 1 character or more than 140 is not permitted.

Given that P = (-5, 5) and Q = (-13, 10), find the component form and magnitude of 2 vector PQ.
tester [12383]
Define the unit vectors along the x and y axes as \hat{i}, \, \hat{j} correspondingly.

Consequently, the vector from P to Q is
\vec{PQ} = (-13+5)\hat{i} + (10-5)\hat{j} = -8\hat{i} + 5\hat{j}
In terms of components, vector PQ is represented as (-8,5).

The magnitude of vector PQ can be calculated as
√[(-8)² + 5²] = √(89) = 9.434

Answer:
Thus, vector PQ is (-8, 5), and its magnitude equals √89 (or 9.434).
