Answer:
n ≥ 3
Step-by-step explanation:
add (-5) to both sides of equations. Solve for n.
Answer:
E
Step-by-step explanation:
E is the only option where the answer would be a non--repeating answer, which is pretty much the definition of a rational number.
Answer:
32.5
Step-by-step explanation:
d
Answer:
10859.94
Step-by-step explanation:
To solve this, you need to know the formula for solving the area of a circle: πr²
The first thing you should do is find the area of the square: 78 x 78 = 6084
Then, we find the area of the circle. To do this, we must figure out the radius. Luckily, the problem states that the combined diameter of both half circles is 78, which means the radius is 39. Then, we can apply the formula: π39².
39² = 1521
1521 x 3.14 = 4775.94
This is the combined area of both half circles.
Finally, we have to add: 4775.94 + 6084 = 10859.94
