Let's start by evaluating the parenthesis on the right. Because of the order of operations (PEMDAS - parenthesis, exponents, multiplication/division, addition/subtraction), we divide 3 by 1/8 first. This is equal to multiplying 3 * 8, or 24. Next, we subtract 5 from 24. This is equal to 19.
Next, we subtract 19 from 3/4. -18 1/4 We complete this problem by adding (1/2)^2, or 1/4. This is: -18 1/4 + 1/4 = -18, so -18 is the answer.
Answer:
The answer is 18/40

3,868,000,000 in scientific notation is 3.868*10^9
Answer:
Step-by-step explanation:
The area outside of the semicircle is the difference of the areas of the rectangle and the semicircle.
<u>Area of rectangle:</u>
<u>Area of the semicircle:</u>
<u>The area we are looking for is:</u>
- A = A₁ - A₂
- A = w² + 5w - 1/8πw²
Correct choice is A
For x=3, the denominator is equal to 0 and you can't divide by 0.
