Amusement Parks a ride at the amusement park consists of an observation deck that travels directly up into the air at the constant rate of 40 feet per second .Its height in feet after t second is given by h=40t .At the instant the deck is at ground level a ball is thrown up with initial velocity 60 feet per second from ground ,The height in feet of the ball after t second is given by h=16t2+60t .Find the time it takes for the ball and the deck to reach the same height round your answer to the nearest hundredth

78.59 is the mean

step-by-step explanation:

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
