Answer:
Perimeter = 86.4 (m)
Step-by-step explanation:
A square (with side x) has an area of 466.56 (m^2)
=> x^2 = 466.56
=> x = sqrt(466.56) = 21.6
=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)
Hope this helps!

Answer:
$3780
Step-by-step explanation:
Salary per month = $10500
Expense on food
= 36% of the monthly salary
= 36% of $10500
= (36/100) × $10500
= 36 × $105
= $3780
So, they spend $3780 on food per month.
Answer:

Step-by-step explanation:
1) The (missing) options are:
a) The number of people that are being studied.
b) red blood cell count
c) height
d) none of the above
2) Explanatory variables are synonymical terms for independent variables.
In short when those variables are really not affected by other ones they are also called Explanatory Variables.
It is useful to make a distinction between response variable, and explanatory ones. The first one is affected somehow and it is the response Doris wants to find out.
3) Certainly, the sample or population of this research is absolutely free of prior influence over the final results. Since theoretically, the same research can be done over different samples and find other responses.
Then it's "a"
The ? Is 11.
You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
