The temperature in degrees Fahrenheit at a given location goes through a similar cycle each day. The low is 30 degrees F and occurs near 6:00 am. The high is 70 degrees F and occurs near 6:00 pm which function best models the temperature as a function of the time in hours since noon?

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

well since the real answer is 8.9 i guess the estimation would be 9

the answer that you are looking for is 9,9

step-by-step explanation: this is the answer because i licked 9 people´s toes and they licked 9 other people toes so thats my proof

for green it is 5: 20 ratio an for red it is 7: 20

hope this : ) : 3
