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.
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
What is the solution
-3x + y = 2
y = x + 4
Answer:
to find the solution, we substitute y = x + 4 into the other equation.
-3x + (x + 4) = 2
-3x + x + 4 = 2
-2x = 2 - 4
-2x = -2
x = 1
to find y, we substitute x to the x variable in the y equation.
y = 1 + 4
y = 5
therefore, when combined, it is (1,5).

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

What is XY? .........................
Answer: B i guess
Step-by-step explanation:
The hypotenuse side XY of given right angle at Z is [tex]5\sqrt{2}[/tex].
Given that in triangle XYZ :
∠X=45°
∠Y=45°
XY=5
And right angled at Z, that is, ∠Z=90°.
Since, ∠X=∠Y=45°
Therefore, XZ=YZ=5
Now,
[tex]\sin \theta = \dfrac{hypotenuse}{opposite}[/tex].
Here, θ=45°.
Therefore,
[tex]\sin \theta=\dfrac{5}{XY}\\\\\sin 45\°^=\dfrac{5}{XY}\\\dfrac{1}{\sqrt{2} } =\dfrac{5}{XY}\\\\XY=5\sqrt{2}[/tex]
Thus, the side XY=[tex]5\sqrt{2}[/tex].

Mason download an app for four dollars. The app has a monthly fee of three dollars per month. Tatum download the same app that cost $20 and has monthly fees of one dollar per month how many months before Mason and Tatum had paid the same amount?
Step-by-step explanation:
step 1. let Mason = m and Tatum = t
step 2. m = 3x + 4 ($3/month and one time $4)
step 3. t = 1x + 20 ($1/month and one time $20)

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:

Brainliest to whoever answers first!!!Z'(5, -7) is the image of Z after a reflection
in the line y=x. What are the coordinates
of Z?
Answer:
I think its Z (-5, 7)
Step-by-step explanation:
Here :)
The coordinates of Z is (7, -5).
Given that, Z'(5, -7) is the image of Z after a reflection in the line y=x.
We need to find the coordinates of Z.
What is the reflection in the line y=x?When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
So, the coordinates of Z become (7, -5).
Therefore, the coordinates of Z is (7, -5).

someone help I don't know this trig question
Answer:
Bill is 9.80 km apart from Concert
Step-by-step explanation:
It's given in the question,
m∠B = 75°
m∠C = 45°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
m∠A + 75° + 45° = 180°
m∠A = 180° - 120°
m∠A = 60°
By sine rule,
[tex]\frac{\text{sin}(\angle A)}{BC}=\frac{\text{sin}(\angle C)}{AB}[/tex]
[tex]\frac{\text{sin}(60)}{BC}=\frac{\text{sin}(45)}{8}[/tex]
BC = [tex]\frac{8\text{sin}(60)}{\text{sin}(45)}[/tex]
= 9.80 km
Therefore, Bill is 9.80 km apart from Concert.

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.
