Answer:
23 males and 12 females
Step-by-step explanation:
x = # of females
y = # of males
x + y = 35
x + x + 11 = 35
2x + 11 =35 (SUBTRACT 11 FROM BOTH SIDES)
2x = 24 (DIVIDE BOTH SIDES BY 2)
x = 12 females
x + y =35
12 + y = 35 (SUBTRACT 12 FROM BOTH SIDES)
y = 23 males
23 males + 12 females = 35 students

Answer: The maximum revenue is $1,000,000.
The function that is given is a quadratic equation and the graph would be an upside down parabola.
Therefore, the maximum revenue would be at the vertex of the parabola.
To find the vertex, we can use the expression -b/2a to find the x-value.
It would be -4000/2(-4) = 500
Now, input 500 for p and you will get a revenue of 1,000,000.
Answer:
103.62 cm squared :)
Step-by-step explanation:
To solve this problem, lets start with the grey area only and essentially we want to treat it like it's own circle. So the formula for circular area is A=pi times r²
so for the radius of the grey region, we will simply add 3 and 4 cm.
3+4=7cm
Then we can plug that into the area equation, which is:
A = (3.14)(7²)
Solve for that and we should get 153.86 cm²
We'll hold onto that for now while we solve for the white circle next:
A = (3.14) (4²)
A = 50.24cm²
Lastly, let's bring back the grey area we found earlier, and subtract the white area from it:
153.86 - 50.24 = 103.62 cm²
hope this helps and good luck~
