simone race 280 kilometers from perry to medford and the idled back. If the round trip took 7 hours, what was simone's average speed in kilmeters per hour?

step-by-step explanation:

mean or average is 40.6

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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
