The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x²+180x . The cost, in dollars of producing the televisions can be modeled by 3x² - 160x +300. The variable x is the number of televisions sold. If 150 televisions are sold, what is the profit?
We use the profit concept, and doing this, it is found that if 150 televisions are sold, the profit is $50,700.
-------------------------------------------
Profit is given by revenue subtracted by cost.
In this question:
Revenue: [tex]R(x) = 3x^2 + 180x[/tex]Cost: [tex]C(x) = 3x^2 - 160x + 300[/tex]Thus, the profit of selling x televisions is:
[tex]P(x) = R(x) - C(x)[/tex]
[tex]P(x) = 3x^2 + 180x - (3x^2 - 160x + 300)[/tex]
[tex]P(x) = 3x^2 + 180x - 3x^2 + 160x - 300[/tex]
[tex]P(x) = 340x - 300[/tex]
-------------------------------------------
For 150 televisions, we have P(150), so:
[tex]P(150) = 340(150) - 300 = 50700[/tex]
If 150 televisions are sold, the profit is $50,700.

x = 45 (Simplify)
Answer:
45
Step-by-step explanation:
1/3x = 15
Multiplying 3 on both sides,
3(1/3x) = 15(3)

Which of the following is NOT equal to ? 3/4
Answer: D
Step-by-step explanation:
3/4 is equal to 0.75.
A is pretty easy. You just add the numerator and get 3/4. So, that is NOT the answer.
B is 9/12. If you divide 9 and 12, it gives 0.75, which is equal to 0.75. This NOT the answer.
C is 6/8 and simplifies into 3/4 so is this is NOT the answer.
D is 3/12 and when you dividere the umerator and the denominator, it gives 0.25 or 1/4, which isn’t equal to 3/4. This IS the answer.
Hope this helped!
The expression that is not equal to 3/4 will be 1/12 + 2/12. Then the correct option is D.

1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 6 / 8
1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 = 3 / 4
C. 3 / 12 + 6 / 12, then the value of the expression is given as,
3 / 12 + 6 / 12 = 9 / 12

1. Rebecca was asked to create five pairs of like terms. Determine if she completed the task
correctly and correct any errors.
Answer:
everything but 2 and 5 was correct
Step-by-step explanation:
Like terms are those terms that are having the same variables, also the variables are of the same order as well. There are two wrong pairs in given pairs of like terms.
What are Like terms?Like terms are those terms that are having the same variables, also the variables are of the same order as well.
For example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
Rebecca is wrong because she had made a pair of (1/2)x and (1/2), which is wrong. Also, pairs 5a and 5b are wrong. This is because in each of the two pairs the terms do not have the same constant term with them.
Therefore, we can write the terms as,
2.5w and -8w → Already correct(1/2)x and (1/2) → (1/2)x and (1/2)x38 and -15 → Already correct-7c² and c² → Already correct5a and 5b → 5a and 5a or 5b and 5bHence, there are two wrong pairs in given pairs of like terms.

Two trains leave the station at the same, one heading west and the other east. The westbound train travels at 55 miles per hour. The eastbound train travels at 75 miles per hour. How long will it take for the two trains to be 156 miles apart?
The time that taken for the two trains is 1.2 hours.
The computation of the time taken for the two trains is shown below:
Given that
The westbound train travels 55 miles per hour.
And, the eastbound train travels 75 miles per hour.
So, the total speed is
= 55 miles per hour + 75 miles per hour
= 130 miles per hour
The distance is 156 miles
So, the time taken is
[tex]= \frac{distance}{speed}\\\\= \frac{156\ miles}{130\ miles\ per\ hour}\\\\[/tex]
= 1.2 hours
Therefore we can conclude that the time that taken for the two trains is 1.2 hours.
Learn more about the speed here: brainly.com/question/21791162
Answer:
1.2 hours
Step-by-step explanation:
Given data:
Speed of the westbound train = [tex]55 miles/hr[/tex]
Speed of the eastbound train = [tex]75 miles/hr[/tex]
Since the trains are moving in the opposite direction their relative speed becomes,
[tex]55 miles/hr +75 miles/hr=130 miles/hr[/tex].
Since, time = distance / speed
Now the time taken for the two trains to be 156 miles apart
[tex]time = \frac{156 miles}{130 miles/hr} \\=1.2 hours[/tex]
Hence, the time taken for the two trains to be 156 miles apart = [tex]1.2 hours[/tex]
