Answer:
The correct Answer is: 9.0 x 10^-3
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5
Step-by-step explanation:
Let,
Cost of each fried crab claw = x
Cost of each gumbo = y
According to given statement;
4x+4y=32 Eqn 1
2x+y = 12.5 Eqn 2
Multiplying Eqn 2 by 2
Subtracting Eqn 3 from Eqn 1
Dividing both sides by 2
Putting y=3.5 in Eqn 2
Dividing both sides by 2
The cost of each order of fried crab claw is $4.5 and cost of each cup of gumbo is $3.5

Answer:
The revenue function
R(x) = - 2x² +490x +2500
Step-by-step explanation:
<u><em>Explanation:-</em></u>
The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x
The price p in dollars that the company can charge for the product is given by p(x) = x + 5
Revenue = price × demand
Revenue = p(x) × d(x)
Revenue = (x+5) ×(500-2x)
Revenue = x(500-2x)+5(500-2x)
Revenue = 500x - 2x² + 2500- 10x
Revenue = - 2x² +490x +2500
Answer:
Sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
Step-by-step explanation:
I'm not sure where you are from, but usually you are allowed to use a calculator. (At least I was when I took Algebra 2/Trig in 6th grade.)
You never specified radians or degrees so I will answer both.
sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
If you are not allowed to use a calc, then I suggest looking at unit circle videos on Khan Academy.
Three times two because when there is no space in a algebric expression itś called multiplication
