Step-by-step explanation:
12 i think so because i did it before
Answer:
Step-by-step explanation:
height of pyramid = √(10²-(5/2)²) = √93.75
volume of pyramid = ⅓b²h = ⅓·5²√93.75 ≅ 80.69 in³
lateral area = 2×5×10 = 100 in²
base area = 5² = 25 in²
surface area = 100+25 = 125 in²
Answer:
15%
Step-by-step explanation:
Ok so if you have to get rid of 25% of 16 than thats 12 because 4 quarters is 100 than you have to think how much does he have know which is 75% so three more types of birds adds 15% and 75 + 15= 90 and the increase was 15% so The answer is 15%
Answer:
Step-by-step explanation:
Let x be the price increase.
<u>Then the current price is: </u>
<u>Then the number of passengers is:</u>
<u>Then the revenue: </u>
- Revenue = Price * Number of Passengers
- R = (50 + x)(8000 − 100x) =
- - 100x² + 3000x+ 400000
This is a quadratic relationship. Maximum point is obtained at vertex.
<u>Vertex is determined by x = - b/2a, find the value of x:</u>
- x = - 3000 / (-2*100) = 15
<u>The maximum revenue is:</u>
- R = (50 + 15)(8000 − 100 * 15) = 424500
