If you sleep 45 minutes in each class, with 4 classes per day, how many hours do you sleep in one school year? 60 minutes = 1 hour. 180 days = 1 school year

45x4=180 180x180=324000/60=5400

Step-by-step explanation:

in 2010, the population of the state of california is 37.29 × 10⁶

step-by-step explanation:

population of los angeles = 3.79 × 10⁶

population of california = 9.84 × population of los angeles

                                        = 9.84 × 3.79 × 10⁶

                                        = 37.2936 × 10⁶

                                        = 37.29 × 10⁶

∴ in 2010, the population of the state of california is 37.29 × 10⁶

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
