Answer:
Step-by-step explanation:
We are given the following in the question:
Relation to convert Fahrenheit into Celsius:
Temperature range: -40°C and 125°C
Thus, we can write the inequality:
where x is the temperature in Celsius.
Converting the temperature in Fahrenheit.
is the range of temperature in Fahrenheit that the anti freeze protect the car.
Let the distance of the engineer from the base of the building be x, then
tan 38 = 300/x
x = 300/tan 38 = 300/0.7813 = 383.98
Therefore, the distance from the engineer to the base of the building to the nearest whole foot is 384 feet.
Answer:
$390+0.07s=$544+0.05s Subtract $390 from each side.
0.07s=$154+0.05s Subtract 0.05s from each side.
0.02s=$154 Divide each side by 0.02.
s=$7700 Both plans pay the same when sales=$7700
ANSWER With sales greater than $7700, Chris is better off with Plan A.
