Answer:

320

Step-by-step explanation:

By analyzing the sequence carefully, we notice that each number (n) is being multiplied by 4.

Therefore, the next integer in the sequence will be the most recent integer (n) multiplied by 4.

In that case, we have 80 * 4 = 320 as our final answer.

A square is inscribed in a circle . If the area of the square is 9 inch square what is the ratio of the radius of the circle to
OLga [1]

Answer:

  (√2)/2

Step-by-step explanation:

The ratio of the radius of the circle to the side of the inscribed square is the same regardless of the size of the objects.

The radius of the circle is half the length of the diagonal of the square. For simplicity, we can call the side of the square 1, so its diagonal is √(1²+1²) = √2 by the Pythagorean theorem. The radius is half that value, so is (√2)/2. The desired ratio is this value divided by 1.

Scaling up our unit square to one with a side length of 3 inches, we have ...

  radius/side = ((3√2)/2) / 3 = (√2)/2

_____

A square with a side length of 3 inches will have an area of (3 in)² = 9 in².

350 + 4x = 750

x = the amount the fee went up annually. 

4x = 750 - 350
4x = 400
x = 400/4
x = 100

The rate of change is 100 dollars per year. The initial value of her business is 350 dollars. To check your work (aka how do you know) if you add 100 dollars to her initial value (350) 4 times you get 750.
