Answer:
100% - 15 % = 85 %
So, $21.08 represents the 85% sale price
What number represents the other 15% of the original price?
(21.08 x 15) / 85 = 3. 72
$21.08 + $3.72 = $24.80 which is the original price.

Piensa y escribe un caso estadístico en el que pueda identificar POBLACIÓN, MUESTRA, VARIABLE Y RECORRIDO DE LA VARIABLE
ANSWER:
Caso estadístico: Altura de las mujeres de la poblacion indigena Sikuani.
Step-by-step explanation:
Población: Mujeres de la comunidad sikuani
Muestra: se toma una muestra de 20 datos para calcular la altura ,este dato se toma de la población total de 165 mujeres.
M: ( 1.30, 1.20, 1.50, 1.52, 1.60, 1.37, 1.28, 1.55,1.46, 1.26, 1.57, 1.58, 1.54, 1.38, 1.56, 1.23, 1.59, 1.62, 1.48, 1.40)
Variable: Altura
Recorrido de la variable: El recorrido de la variable es la diferencia entre el valor máximo de la muestra y el valor mínimo.
Altura máxima: 1.62 m.
Altura mínima : 1.20
Como ya tenemos el valor máximo y el valor mínimo ,podemos hallar el recorrido de la variable.
R=( 1.62m -1.20m)
R= 0.42

Find all exact solutions
2cos^2x=sinx+1
Please show work thank you!
Answer:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]2\cos^2(x)=\sin(x)+1[/tex]
And we want to find all solutions for x.
First, we should put the equation into terms of only one trigonometric ratio.
Since we are given cos²(x), we can turn this into sine. Recall the Pythagorean Identity which states:
[tex]\sin^2(x)+\cos^2(x)=1[/tex]
Therefore:
[tex]\cos^2(x)=1-\sin^2(x)[/tex]
By substitution:
[tex]2(1-\sin^2(x))=\sin(x)+1[/tex]
Distribute:
[tex]2-2\sin^2(x)=\sin(x)+1[/tex]
Isolate the equation:
[tex]2\sin^2(x)+\sin(x)-1=0[/tex]
We can factor:
[tex](2\sin(x)-1)(\sin(x)+1)=0[/tex]
Zero Product Property:
[tex]2\sin(x)-1=0\text{ or } \sin(x)+1=0[/tex]
Solve for each case:
[tex]\displaystyle \sin(x)=\frac{1}{2}\text{ or } \sin(x)=-1[/tex]
We can use the unit circle.
sin(x) = 1/2 for every π/6 and 5π/6. So, it will continue every 2π.
sin(x) = -1 every 3π/2. And this will also continue every 2π.
Hence, our solutions are:
[tex]\displaystyle x=\left\{\frac{\pi}{6}+2n\pi, \frac{5\pi}{6}+2n\pi, \frac{3\pi}{2}+2n\pi\right\}, n\in\mathbb{Z}[/tex]
Note:
If you only need the solutions within the interval [0, 2π), then it is:
[tex]\displaystyle x=\left\{\frac{\pi}{6}, \frac{5\pi}{6}, \frac{3\pi}{2}\right\}[/tex]

Which of the statements about the graph is true? :((
Answer: D / none are true
Since it's proportional (it's a straight line), B and C are automatically wrong. A would seem true at first glance, BUT if you look closely at the graph, the slope of the graph is actually 2x.
Look at the beginning of the line. It starts at 18 (x = 0/y intercept) and at x = 1, you can see that y is at 16. The y value goes down by 2 every time x increases by 1. This means that the equation of the graph is -2x + 18 = y.
The graph is proportional and has an equation of y = -2x + 18. This means that A, B and C are incorrect.
Answer:
Your answer is D.Step-by-step explanation:
It is a straight line also known as proportional. The first impression, A appears to be accurate, but closer inspection reveals that the graph's slope is actually 2x. 18 (x = 0/y intercept) and ends at x = 1, where little y is at 16. Any time x expands by one, the y value falls by two. This says that the graph's equation is -2x + 18 = y.

52 divided by 6 as a fraction
Answer:
52/6 = 8 and 2/3
Step-by-step explanation:
52 divided by 6 is 8 and 2/3
6 multiplied by 8 is 48
52-48 is 4
so 52/6 is 8 remainder 4
or you can divide 4 by 6
4/6 = 2/3
so it can also be 8 and 2/3
52 divided by 6 as a fraction in its simplest form is 8 2/3.
To express 52 divided by 6 as a fraction, you simply write it as:
52 / 6
To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.
The GCD of 52 and 6 is 2.
Divide both the numerator and denominator by 2:
(52 / 2) / (6 / 2)
This simplifies to:
26 / 3
now, we have,
Divide 26 by 3:
26 ÷ 3 = 8 with a remainder of 2
The whole number part is 8, and the remainder (2) becomes the new numerator.
The denominator remains the same.
So, 26/3 as a simplified mixed number is: 8 2/3
So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

a) x^2 - 10x + 25 = 0
b) x^2 - 4x - 5 = 0
(preciso da montagem da conta, junto com o resultado)
Answer:
Step-by-step explanation:
a) x² - 10x + 25 = 0
(x-5)²=0
x-5=0
x=5
b) x² - 4x - 5 = 0
⇒ ( x 2 − 4 x + 4 ) − 5 − 4 = 0
⇒ ( x 2 − 4 x + 4 ) − 9 = 0
( x − 2 ) 2 − 9 = 0 ⇒
( x − 2 ) 2 = 9 ⇒
( x − 2 ) = ± √ 9 (don't forget the ± !) ⇒
x= − 1 x = 5

$97 is what percent of $97?
Answer: 100%
97:97*100 =
(97*100):97 =
9700:97 = 100
Now we have: 97 is what percent of 97 = 100
Question: 97 is what percent of 97?
Percentage solution with steps:
Step 1: We make the assumption that 97 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=97$.
Step 4: In the same vein, $x\%=97$.
Step 5: This gives us a pair of simple equations:
$100\%=97(1)$.
$x\%=97(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{97}{97}$
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{97}{97}$
$\Rightarrow x=100\%$
Therefore, $97$ is $100\%$ of $97$.
Answer:
100%

Drag the correct number of pieces to show how to find the area of the shaded figure in two different ways. Pieces can be rotated to fit.
Answer:
Step-by-step explanation:
As you can see from the attached picture below, the only figure that is equal to 5 whole units would be the final triangle. That is because it has 2 whole units in the middle, two half units in the top which equal 1 whole unit. And 2 units in each side corner which when combined would equal 2 whole units making it a total of 5. The rest of the shapes either hold more than 5 or less than 5 units. In the picture below, the top 3 shapes hold more than 5 units while the bottom two triangles hold less than 5.

Sia sells large candles for $3 each and small candles for $2 each. She sold 17 candles for $46.00. How many of each size candle did she sell? 4 small and 13 large candles 5 small and 12 large candles 12 small and 5 large candles 13 small and 4 large candles
Answer:
The number of large size candles sells are 12 and the number of small size candles are 5 .
Step-by-step explanation:
As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y. Equation becomes
x + y = 17
3x + 2y = 46
Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .
3x - 3x + 2y - 3y = 46 - 51
-y = - 5
y = 5
Put in the equation x + y = 17 .
x + 5 = 17
x = 17 - 5
x = 12
Therefore the number of large size candles sells are 12 and the number of small size candles are 5

a plane departs an airport and mistakenly travels due west at 500mph for 30 minutes. the pilot realizes that the correct destination (airport b) was actually 600 miles away at a bearing of 60 degrees west from airport a. how far is the airplane from its original destination now?
Answer:
403 miles
Step-by-step explanation:
500 mph is 500 miles per hour
30 minuites is half an hour, so that is 250 miles west
60 degrees west, 600 miles away
so it is a triagle of 30 60 and 90.
600 is the hypotenuse of the 30 60 90 triangle
we need to find the height of the 30 60 90 triangle
using the special rule, the height is 300
the length of the 30 60 90 triangle is 300rt3
so 300rt3 - 250 is the length of another triangle.
height is still 300
hypotenuse is the distance of the actual area minus the plane's current position
(300^2 + (300rt3-250)^2)^1/2 is about 403.351433
