Morten Andersen played in NFL for 25 years write and solve an equation to find how many points he averaged each year
soldi70 [24.7K]

Answer:

r =\frac{2437points}{25 years} =97.45 \frac{points}{year}

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

Step-by-step explanation:

Assuming the following table on the figure attached.

We see that the career points for Morten Andersen was 2437. That include all the points over alll the years the he played in the NFL.

Since the total years played by Morten Andersen was 25 we can write the following equation:

25 r =2437

Where r represent the rate of points average per year.

If we solve for r from the last equation we can divide both sides of the equation and we got:

r =\frac{2437points}{25 years} =97.45 \frac{points}{year}

So then we have that Morten Andersen scored on average 97.45 points per year in his career.

How do you determine the area of a circle? Could you give an example please?
pickupchik [31]
To determine the area if the circle, you must know the diameter or the radius of a circle.

If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)
a = \pi {r}^{2}
If you know the diameter, just divide the diameter to get the radius then use the same equation.

Answer:

Gross pay per days is 5h+8 dollars
