Answer: 10.5 gallons
Step-by-step explanation:
One imperial gallon is approximately 1.2 US gallons. The US gallon is used in the United States and is equal to exactly 231 cubic inches or 3.785411784 liters. The Imperial gallon or UK gallon is used in the United Kingdom and is equal to approximately 277.42 cubic inches. Its exact value is defined as 4.54609 liters.
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million
All you have to do is subtract 18 from 45 and divide that sum by 3, because 3 bags of birdseed were bought. If she spent $45, then 18 dollars were spent on a birdfeeder and three bags of birdseed costs $27 all together. 27 divided by 3 is 9, so each bag of birdseed costed $9. :)
F ( x ) = - 2 x² + 12 x + 5 = - 2 ( x² - 6 x ) + 5 = - 2 ( x² - 6 x + 9 - 9 ) + 5 =
- 2 ( x² - 6 x + 9 ) + 18 + 5 = - 2 ( x - 3 )² + 23
f ( x ) = a ( x - k )² + h ( the vertex form ), k = 3, h = 23.
a = - 2 < 0, that means the vertex coordinates ( 3, 23 ) represents a maximum.
