4%16 is 4 so 4 is the answer mark branlist
We need to convert both speeds into meters per minute.
27 km/h * (1000 m)/(1 h) * (1 h)/(60 min) = 450 m/min
14 dm/s * (1 m)/(10 dm) * (60 s)/(1 min) = 84 m/min
The difference in speeds is 450 m/min - 84 m/min = 366 m/min
Answer:
Step-by-step explanation:
<u>Given function:</u>
<u>Vertex form:</u>
Axis of symmetry is the line parallel to y-axis and passes through vertex. The x-coordinate of the vertex is determined by the value of h in the above equation.
We have h = 3 as per given equation for the function.
Axis of symmetry is the line x = 3
Answer:
216
Step-by-step explanation: 270-20%= 216
Answer:
In 2009
Step-by-step explanation:
If the wren population is going down by 40% each year, that means the following year's population is just 60% of what was in the previous year. This means that what we have to do is multiply the previous year's number by 0.6 to get the current year's population. If we take the data from 2004 as 100%, we have the following numbers:
2004 = 100%
2005 = 60 % (100 * .6)
2006 = 36 % (60 * .6)
2007 = 21.6 % (36 * .6)
2008 = 12.96 % (21.6 * .6)
2009 = 7.776% (12.96 * .6)
This means that 2009 will show that the wren population is less than 10% (7.776%) than what it was in the year 2004.
I hope this helps! :D
