The correct answer for the expression 20 + 20 × 0 + 1 by applying the rule of PEMDAS is equal to 21.
To explain in detail, we follow the order of operations (also known as PEMDAS ) to solve this expression step by step:
Parentheses Exponents Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)
Let's solve the expression step by step:
20 + 20 × 0 + 1
20 + (20 × 0) + 1 [There are no parentheses or brackets]
20 + (0) + 1 [Perform the multiplication first (20 × 0 = 0)]
20 + 0 + 1 [Perform the addition (20 + 0 = 20)]
20 + 1 [Perform the addition (20 + 1 = 21)]
Therefore , the value of the given expression is equal to 21.

Answer:
52
Step-by-step explanation:
We can find the percent of a number by converting the percent to a decimal.
65%=0.65
80(0.65)=52
To find 65% of 80, first write 65% as a decimal by moving the decimal point 2 places to the left and we will get .65. Next, the word "of" means multiply, so we have (.65) (80) = 52.
Therefore, 65% of 80 is 52.
