I am torn between B and D because increased means add, but I am going to go with B 1 - 3n. I choose B because in the D option it decreases not increases.

So the answer is B.) 1 - 3n

my answer is a bit different but kinda similar ig.

254.34in^2

Step-by-step explanation:

Radius = Diameter/2 18/2 = 9

Area of circle= pi(3.14) x r^2

A= (3.14) x 9^2

A= (3.14) x 81

A= 254.34in^2

A seagull was flying about sea level looking to catch a fish below sea level. The elevation above sea level was 125 1/2 feet. He

frez [133]

Answer:

The seagull's position halfway is 85.5 feet.

Step-by-step explanation:

The seagull is at 125 1/2 feet above the sea level.

The fish is at 45 1/2 feet below the sea level.

The distance between the seagull and fish = seagull's distance above the sea level + fish's distance below the sea level

= 125 1/2 + 45 1/2

= $\frac{251}{2}$ + $\frac{91}{2}$

= $\frac{342}{2}$

= 171

The distance between the seagull and fish is 171 feet.

Since the seagull stops halfway, then;

seagull's position = $\frac{171}{2}$

= 85.5

The seagull's position halfway is 85.5 feet.
