Answer:
It is a simple interest account
Step-by-step explanation:
As we might see from the given earnings, the amount of money he earned each year is the same as in the previous year. This means that the amount of money is growing linearly instead of exponentialy. This is characteristic to a simple interest account, which is found by using the formula:
I=Prt
where I = interest earned.
P = principal
r = Interest rate
t = time in years,
if we use this formula to calculate the amount of money earned after t years, we can see it will be the same as the values reported:
I=$300(0.02/year)(1year)=$6
I=$300(0.02/year)(2years)=$12
I=$300(0.02/year)(3years)=$18
So this simple interest account.
Answer: 
Step-by-step explanation:
The missing figure is attached.
The volume of grain that could completely fill this silo is the sum of the volume of the cylinder and the volume of the hemisphere.
By definition, the volume of a cylinder can be calculated with this formula:

Where "r" is the radius and "h" is the height.
In this case you know that:

And the volume of a hemisphere can be found using the following formula:

Where "r" is the radius.
In this case:

Therefore, the volume of grain that could completely fill this silo, rounded to the nearest whole number, is:

The answer is c because if the survey says 3 out of 8 have one you divide 3/8 and multiply it by 192.
