(4logs/2hours) = (x logs/8 hours)
(4/2) = x/8)
Cross multiplication gets you:
(4)(8) = (2)x
32 = 2x
x = 16
16 logs
Answer:
29.92 m² (nearest hundredth)
Step-by-step explanation:
Area of rectangle = width × length
⇒ area = 4 × 5.5 = 22 m²
Total area = area of sector + area of rectangle
⇒ total area = 
= 29.91943148... = 29.92 m² (nearest hundredth)

Answer:
42%
Step-by-step explanation:
The first step is to calculate the difference in the number of fishes from the beginning of the day to the end of the day.
90 -52
= 38 fishes
Therefore the percent decrease can be calculated as follows
= 38/90 × 100
= 0.422 × 100
= 42.2 %
= 42% ( to the nearest cent)
The cost function is
c = 0.000015x² - 0.03x + 35
where x = number of tires.
To find the value of x that minimizes cost, the derivative of c with respect to x should be zero. Therefore
0.000015*2x - 0.03 = 0
0.00003x = 0.03
x = 1000
Note:
The second derivative of c with respect to x is positive (= 0.00003), so the value for x will yield the minimum value.
The minimum cost is
Cmin = 0.000015*1000² - 0.03*1000 + 35
= 20
Answer:
Number of tires = 1000
Minimum cost = 20
