I am also answering that same question on a website for algebra and have the same question and i think the answer is A.
Answer:
See the attached image for solutions.
Step-by-step explanation:
X-ray vision to all students ratio:
<u>6:36</u>, which can be simplified to <u>1:6</u>.
<u />
Flight to all students ratio:
<u>8:36</u>, which can be simplified to <u>2:9</u>.
Flight to inivisibility ratio:
<u>8:36</u>, which can be simplified to <u>2:3</u>.
Hope this helps! :)
A root of a polynomial doesn't mean it is a square root of!!!!!!
P(x)=3(x-5)(x-2)=3x²-21x+30
f (x)= 3 x power point 2 - 21 x + 30
No he would be incorrect because if you add 6 and 8 you get 14 and 14 is an even number. I hope this helps!
Answer:
<em>3.75x = 450 + 1.50x</em>
<em>They should sell 200 bags of popcorn to break even</em>
Step-by-step explanation:
<u>Business Modeling</u>
When modeling the operation of a business, there are some magnitudes that should be managed to properly control the profits of the business. Those magnitudes are Costs, Revenue, and Profits.
The profit is the difference between the costs and the revenue as follows:
P(x) = R(x) - C(x)
Where x is the number of units produced and sold.
The break-even level is the value of x that produces zero profits, i.e.,
R(x) = C(x)
The costs associated to sell popcorn consist of a fixed amount of $450 plus a variable cost of $1.50 for every popcorn. Thus the total cost function is:
C(x) = 450 + 1.50x
The income or revenue is the selling price times the number of popcorns:
R(x) = 3.75x
The break-even level can be calculated by solving the equation:
3.75x = 450 + 1.50x
Solving the equation:
3.75x - 1.50x = 450
2.25x = 450
x = 450/2.25
x = 200
They should sell 200 bags of popcorn to break even
