Answer:
1/2 times 2/3 equals 0.333333....
that plus 0.345 equals 0.678
Step-by-step explanation:
Answer:
It is perpendicular
Step-by-step explanation:
The initial temperature difference of 101-45 = 56 degees declined to 101-55 = 46 degrees in 8 minutes, We can write the exponential equation for the soda's temperature as
... T = 101 -56(46/56)^(t/8) . . . . where t is in minutes
After an additional 10 minutes, we have t=18, so the soda temperature will be
... T = 101 -56(46/56)^(18/8) ≈ 65.0 . . . degrees
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
