Answer:
A.) 11

Explanation:
To estimate the sum of these numbers, simply add the whole numbers of 9 and 1:
9 + 1 = 10
and then judge what the fractions will add up to roughly. 12/15 is almost 1, and it is more than 1/2, so it will round up to 11.

But to be sure you can check:
9 12/15 + 1 2/6
9 24/30 + 1 10/30 = 10 34/30 = 11 4/30 = 11 2/15

Answer: x = 8

(the correct answer was not provided as an option)

Step-by-step explanation:

$log_2(x-6)+log_2(x-4)=log_2(x)\\\\log_2[(x-6)(x-4)]=log_2(x)\\\\(x-6)(x-4)=x\\\\x^2-10x+24=x\\\\x^2-11x+24=0\\\\(x-3)(x-8)=0\\\\x=3\qquad x=8\\\\\\\text{The term after the log symbol (inside the parenthesis) must be greater than 0!}\\\\Check:\\3-6>0\ \text{FALSE --- so 3 is not a valid solution}\\\\8-6>0\ \text{TRUE}\\8-4>0\ \text{TRUE}\\8>0\ \text{TRUE --- 8 is a valid solution because it is true for all}$

So. At oaknoll school 90 out of 270 students own computers. What percent of students at oaknoll school do not own computers? Rou

Arada [10]

Answer: There have 66.66..7% of Student own computer(s).

Step-by-step explanation:

What I did is make the whole school (270) be 100%, then I subtract from Whole school to own computer and the answer will be not own computer: 270 - 90 = 180, so there has 180 students who do not own computer, but we want to find the percentage. So we multiply 180 and 100, we will get 18,000! Then divide it to 270 and we will get 66.66..7, write it on top of 100, so it would be 66.66../100 which mean 66.66..% or 66.66..7%

Hopefully that’s helpful, if not then look the attachment include this answer to help better understanding. Good luck!
