There is a total of 720 students are in Ridgewood Junior High School.
Given,
All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday.
5% of students brought their lunch.
36 students brought their lunch.
To determine how many students in total are in Ridgewood Junior High School.
the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Let there be x students in the Ridgewood Junior High School.
5% of students brought their lunch and equal to 36
so 5% of x = 36
5/100 * x = 36
x = 36*100/5
x = 36*20
x = 720
Thus, there is a total of 720 students are in Ridgewood Junior High School.

If f(x) = 11 - 6(x - 8), what is f(-3)?
Answer:
We conclude that:
[tex]f\left(-3\right)=77[/tex]Step-by-step explanation:
Given the function
[tex]f(x) = 11 - 6(x - 8)[/tex]
Important Tip:
In order to determine f(-3), all we need is to substitute x = -3 in the function equationsubstitute x = -3 in the equation
[tex]f(x) = 11 - 6(x - 8)[/tex]
[tex]f(-3) = 11 - 6(-3 - 8)[/tex]
[tex]f\left(-3\right)\:=\:11-\left(-66\right)[/tex]
[tex]f\left(-3\right)\:=\:11+66[/tex] ∵ Apply rule -(-a) = a
[tex]f\left(-3\right)=77[/tex]
Therefore, we conclude that:

Tori bought one share of Macy's stock on Nov 1, 2016 for $33.38.
Four years later, she sold it and the closing price for that day was
$5.09. a) How much money did she gain/lose with this stock?
b) What is her rate of return?
Tori's loss from the stock will be $28.29 and her rate of return will be -84.75%.
Since Tori bought one share of Macy's stock on Nov 1, 2016 for $33.38 and she sold it and the closing price for that day was $5.09, her loss will be;
= $5.09 - $33.38
= -$28.29
Her rate of return will be:
= -28.29/33.38 × 100
= -84.75%

Side length = [tex]2\sqrt{3}[/tex] in
Step-by-step explanation:
Area of the given hexagon = 6 × (Area of the triangular section)
Area of the triangular section = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(2)(\sqrt{3})^{\frac{x}{12}}(\sqrt{3})^{\frac{x}{6}}[/tex]
= [tex](\sqrt{3})^{\frac{x}{12}}[(\sqrt{3})^2]^{\frac{x}{12}}[/tex]
= [tex](\sqrt{3})^{\frac{x}{12}}(3)^{\frac{x}{12}}[/tex]
= [tex](3\sqrt{3})^{\frac{x}{12}}[/tex]
Now area of the given hexagon = [tex]6(3\sqrt{3})^{\frac{x}{12}}[/tex]
Since, area of the hexagon is = [tex]18\sqrt{3}[/tex] in²
[tex]6(3\sqrt{3})^{\frac{x}{12}}=18\sqrt{3}[/tex]
[tex](3\sqrt{3})^{\frac{x}{12}}=(3\sqrt{3})^1[/tex]
[tex]\frac{x}{12}=1[/tex]
x = 12
Therefore, side length = [tex]2(\sqrt{3})^{\frac{x}{12}}[/tex]
= [tex](2\sqrt{3})^{\frac{12}{12}}[/tex]
= [tex]2\sqrt{3}[/tex] in.
David's money is three times Siti's money. Farid has RM 150 less than Siti. The total amount of their money is RM 2 000. How much do each of them have?
Answer:
Siti's money = RM 430
David = RM 1,290
Farid = RM 280
Step-by-step explanation:
Let
Siti's money = x
David = 3x
Farid = x - 150
Total of their money = RM 2 000
x + 3x + (x - 150) = 2000
4x + x - 150 = 2000
5x = 2000 + 150
5x = 2,150
x = 2,150/5
x = RM 430
Siti's money = x
= RM 430
David = 3x
= 3(430)
= RM 1,290
Farid = x - 150
= 430 - 150
= RM 280

To calculate this distribution, what would you set p equal to? p =
What would q be equal to? q =
What would n be equal to? n =
Answer:
p = 0.35
q = 0.65
n = 7
Step-by-step explanation:
To calculate the distribution, we have the following values;
p = 35% = 35/100 = 0.35
q = 1-p = 1-0.35 = 0.65
n = 7
Answer:
p = 0.35
q = 0.65
n = 7

y = -63 y = 8x + 6
Use Substitution to solve
9514 1404 393
Answer:
(x, y) = (-8.625, -63)
Step-by-step explanation:
Substitute for y.
-63 = 8x +6
-69 = 8x . . . . . subtract 6
-69/8 = x = -8.625
The solution is (x, y) = (-8.625, -63).
5x + 3y = 6
-3x - 3y = 6
Answer:
(x,y)=(6,-8)
x=6, y=-8
Step-by-step explanation:
There are many was to answer this question, some are substitution and elimination. I am going to use the substitution method.
Your system of equation is 5x+3y=6 and -3x-3y=6
5x+3y=6
-5x -5x
3y=6-5x
Now you substittion the first equation to the sencond one. It will look like:
-3x-(6-5x)=6
-3x-6+5x=6
2x-6=6
+6 +6
2x=12
Divide both sides by 2 and you get
x=6
Now lets substiton x inot the orgianl equation.
-3(6)-3y=6
-18-3y=6
+18 +18
-3y=24
Divide both sides by -3
y=-8
So, the answer is x=6, y=-8

step 2. m = 3x + 4 ($3/month and one time $4)
step 3. t = 1x + 20 ($1/month and one time $20)
step 4. 3x + 4 = x + 20 (set equations equal)

Hi! When I type into the calculator and multiply 0.12 and 100 it comes out as 13.2, why is that?
Answer:
because it is a decimal so it multiplies 100 by the decimal which is a smaller number, almost like how when you divide it becomes a smaller number.
Step-by-step explanation:
hope this helps:)
i'm not sure why that is, but the only thing i can assume is that either your calculator is broken somehow or you are accidentally typing in the wrong numbers.
you might also have forgotten to clear your calculator before attempting to put in 0.12 x 100.
i recommend using an online calculator for the time being if your calculator is faulty/having issues.
