Use pemdas (parenthesis, exponents, multiplication/division, addition/subtraction)
(28/4)*5-6+4^2
7*5-6+4^2
7*5-6+16
35-6+16
29+16
45
Your answer should be 45. Remember PEMDAS:)
Answer: ~73.89% of students at school are not freshmen
Step-by-step explanation:
To find a percentage, you need to divide the partial group by the large group. For example, if I have 2 bananas, and 10 fruits, what percentage of bananas do I have? The correct answer would be (2 bananas ÷ 10 fruits), which equals 20% (the equation equals 1/5, or 0.2, but when finding percentages, you multiply the final answer by 100 and add the % sign.).
Now, you have 223 freshmen and 854 students. To calculate the percentage of students at the school other than freshman, you need to find out how many students aren't freshman. Do this by finding the difference of the amount of students in the school and the amount of freshmen.
> 854 - 223 = 631 students that are not freshmen
Use this number to find out the percentage of students that are not freshmen.
> 631 non-freshmen ÷ 854 total students ≈ 73.89%
Answer:
the equation is x^2-16
Step-by-step explanation:
sum:0=+4-4
product:-16=+4*-4
(x-4)(x+4)
when you open the brackets the equation you will obtain will be x^2-16
