Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
Answer:
24 birds
Step-by-step explanation:
Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...
5b +7.5(41 -b) = 247.50
-2.5b +307.50 = 247.50 . . . . . simplify
-2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50
b = 24 . . . . . . . . . divide by -2.5
The number of birds at the shelter on Wednesday was 24.
I believe it is 28 dimes
.25 × 30 = 7.50
.10 × 190 = 19
19 + 7.50 = 26.50
Then, you add 4 more quarters which is 27.50 and the 28 dime makes it 27.60
Answer:
C:
Step-by-step explanation:
Both angles add up to 180°
<BCG + <BFG = 180°
2x+146+4x+238=180
6x+384 = 180°
6x = 180-384
6x = -204
Dividing both sides by 6
x = -34
