Kate walks 5 miles in 2 hours at a steady pace. How far can she walk in 1 hour and 15 minutes? Explain your reasoning.
Answer:
3.125
Step-by-step explanation:
Kate walks 5 miles in 2 hours (120 minutes)
The distance she can works in 1 hour 15 minutes can be calculated as follows
This can be calculated using proportion
d/75= 5/120
Cross multiply
d×120= 75×5
120d= 375
d= 375/120
= 3.125

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]

$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%

Resolva os problemas:
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

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

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
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
