Answer: The answer would be 5.2
Step-by-step explanation:
First change the feet to inches. 80*12=960 Then set up a proportion 960/4=x/1.
You should get 240. I'm pretty sure this is right. :)
Answer:
<em>The freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.</em>
Step-by-step explanation:
The model for the freezing point of water T at altitude a is:
T(a)= 0.0001a+32
The slope of this equation is the coefficient of the variable a. Since the slope is positive, it means the freezing point of water increases by 0.0001 degrees Fahrenheit when the altitude increases by 1 foot.
For example, when a=1000, the freezing point is:
T(1000)= 0.0001*1000+32 = 32.1°F
When a=1001, the freezing point is:
T(1001)= 0.0001*1001+32 = 32.1001°F
Note the increase of 1 foot in altitued meant an increase of 32.1001-32.1 = 0.0001°F
Answer: Collinear, equidistance, and noncoplanar
Step-by-step explanation:
4^3 = 64 so log_4(64) = 3 giving y = 3
