Always use significant figure rules. remember that these rules apply to all numbers that are measurements. a car travels 6 miles north, 3 miles east, and then 2 miles south. what is the distance traveled? a.7 b.11

Option B.

Explanation:

It is given that a car travels 6 miles north, 3 miles east, and then 2 miles south.

We need to find the distance traveled by the car.

North = 6 miles

East = 3 miles

South = 2 miles.

Total distance traveled by the car is

Total distance = 6 miles + 3 miles + 2 miles

Total distance = 11 miles

The distance traveled by the car is 11 miles.

Therefore, the correct option is B.

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
