Answers

Answer 1

Answer: 1. Perry surveyed 60 students at her school.
=> 0.45 of the students said that their favorite subject is math
=> 0.45 x 100 = 45%
Thus, 45 % of 60:
=> 60 * .45 = 27
35% of the student said their favorite is science:
=> 35% / 100 = 0.35
=> 35% 0f 60 equals:
=> 60 * .35 = 21
Thus, 27 – 21 = 6 of the student said that they love math over science.

8+6^2/11+7*2
I don't see any parenthesis.
8+6^2/11+7*2
I see exponents.
6^2=6*6=36
Rewrite the problem.
8+36/11+7*2
Next up is multiplication.
7*2=14
Rewrite it.
8+36/11+14
Division.
36/11=3.27 (repeating)
So round it to 3.28
Rewrite it.
8+3.28+14
Then just add
8+3.28+14=25.28
