a). How many minutes is the dryer used in a month.
Assuming there 30 days in a month;
This shows that the dryer is used 300 minutes in a month.
b). How many hours is the dryer used in a month.
To solve this problem, we simply need to convert the value of (a) from minutes to hours.
The dryer was used for a total of 5 hours in a month.
c). The power of the dryer in kilowatt.
To convert the power in watt to kilowatt, we divide by 1000.
The power in kilowatt is 1.2kw
d). How many kilowatt/hr of electricity used in a month.
The dryer consumes 6kw/h in a month.
e). If the town charges $0.15/kwh, the cost in a month
The cost of the dryer in a month is $0.9.

Answer:
Glacial Striations
Explanation:
Glacier is an erosion agent that transports and deposits sediments.
Due to the weight and gradual flow of a glacier, it carves along parts of the mass beneath it, these parts are known as sediments, this movement causes marks to appear on the land beneath it. These marks are called Glacial Striations.

Force is equal to the mass of that object multiplied by itsacceleration:
F = m × aThe unit of force is N = kg * m/s².
It is given:
m = 0.25 kg
a = 196 m/s²
F = m × a = 0.25 kg × 196 m/s² = 49 N
B.49 N is the ANSWER! I took the test on k12 and it was right

1. First determine the suitable formula for this word problem. Which is a. A=vf-vi/t
Given are: Vf=99.2 km/h Vi= 0.0 km/h T= 4.0sec
Solution:
A= 99.2 km/h – 0.0km/h / 4.0 sec
A = 99.2 km/h / 4 sec
A = 2.8 km/h/sec
Answer:
24.8 km per second
