Answer:
459
Step-by-step explanation:
Conver the fraction into a decimal 3/4= .75
Multiply 36x12.75
And, you get 459 bushels. Hope this helps :D
-2(x+9)-6=-24
-2x-18-6=-24
2x=0
x=0
2(x+9)-6=-24
2x+18-6=-24
2x=-36
x=-18
Answer: A. Infinite number of solutions
Step-by-step explanation:
The given system of equations is expressed as
x + 3y = 5- - - - - - - - - - - - - -1
4x + 12y = 20- - - - - - - - - - - 2
We would apply the method of substitution. From equation 1, we would make x the subject by subtracting 3y from the left hand side and the right hand side of the equation. It becomes
x + 3y - 3y = 5 - 3y
x = 5 - 3y
Substituting x = 5 - 3y into equation 2, it becomes
4(5 - 3y) + 12y = 20
20 - 12y + 12y = 20
20 = 20
Therefore, the system of equations has an infinite number of solutions because as many values of x and y that satisfy the first equation, they would also satisfy the second equation.

Answer:
The function for the outside temperature is represented by , where t is measured in hours.
Step-by-step explanation:
Since outside temperature can be modelled as a sinusoidal function, the period is of 24 hours and amplitude of temperature and average temperature are, respectively:
Amplitude
Mean temperature
Given that average temperature occurs six hours after the lowest temperature is registered. The temperature function is expressed as:
Where:
- Mean temperature, measured in degrees.
- Amplitude, measured in degrees.
- Daily period, measured in hours.
- Time, measured in hours. (where t = 0 corresponds with 5 AM).
If , and , the resulting function for the outside temperature is:
