Since only 30% of the teachers taught for one year, the remaining percentage of the teachers had taught for more than a year, or 70%.
70%=0.7
80(0.7)=56
56 teachers had taught for more than a year.
Answer:
$13,282.83
Step-by-step explanation:
The initial value of the investment is $1400, when t = 0.
The appropriate formula for this exponential growth is
A = Pe^(rt), where r is the exponential rate of change and t is the number of years.
Thus:
A = $1400e^(0.09t). Note that when t = 0, A = $1400 as expected.
After 25 years:
A = $1400e^(0.09*25) = $13,282.83
Answer:
5.5 yd
Step-by-step explanation:
To find the side length of the cube, the volume is a clue. We know that all sides of a square are equal, and the volume of a cube is length×width×height. Since the length, width and height are all the same, we know it is V=x³. Since we know the volume, we can plug in and solve for x.
166=x³
In order to get x alone, we have to cube root both sides.
x≈5.5 yd
So,
We can see that the digit 2 is 4 units to the right of the decimal point, so in order to write it in scientific notation, we will have to move the decimal point 4 places to the right to get 2.
0.000200 in scientific notation is
