Answer:
495
Step-by-step explanation:
This problem can be solved b using a combination. We're using a combination for this because the order in which you would pick the books doesn't matter. To solve, we would plug in the number of books, in this case 12, into the n value of the combination. Then we would plug in the number of books that would be picked, in this case 4, into the r value of the combination. Solve the combination, and you get 495.
The area of a circle is given by A=Pi*r^2, and its perimeter, P=2*Pi*r.
To get the radius r, you must divide 452.2 by Pi, and then calculate the square root of this quotient.
To get the circumference or perimeter, use the radius in the formula P=2*Pi*r.
Finally, round the number you get to the nearest tenth.
By using the PEMDAS order of operations, we get 3(6+7) = 39.
The equation be 3(6+7) then the correct answer is 34.
<h3>What is PEMDAS order of operations?</h3>
The order of operations exists as a law that describes the proper sequence of stages for estimating a math expression. We can recognize the order utilizing PEMDAS: Parentheses, Exponents, Multiplication, Division (from left to right), Addition, and Subtraction (from left to right).
Given: 3(6+7)
By using the PEMDAS order of operations, we get
(6+7) = 13
Then we get
3(6+7) = 3
13
= 39.
Therefore, the value of 3(6+7) = 39.
