Answer:
$37.26
Explanation:
firstly, we find the total original price: $34 + $12 = $46.
next, we can multiply this by 100% - 25% = 75% to find the discounted price:
$46 × 75%
= $46 ÷ 100 × 75
= $34.50
finally, add on the sales tax which is 100% + 8% = 108%:
$34.50 × 108%
= $34.50 ÷ 100 × 108
= $37.26

What is the value of x?
9514 1404 393
Answer:
98
Step-by-step explanation:
The angle bisector divides the triangle proportionally. This means ...
VY/VT = KY/KT
VY = VT(KY/KT)
x = VY +KY = (KY(VT/KT) +KY) . . . . . use the expression for VY
x = KY(VT/KT +1) . . . . . . . . . . . . . . . factor out KY
x = (68)(57/129.2 +1) . . . . . . . . .. put in the numbers
x = 98
Answer:
the answer is x=98

A camper on top of a 400 foot cliff is enjoying the view. They look down and see a
bear at an angle 37 degrees. Approximately how far is the bear from the base of the
cliff? (Round your answer to the nearest foot.). REMEMBER THE UNITS
Answer:
301.42 ft from base
Step-by-step explanation:
We can look at this situation as a triangle, the cliff is straight up and we're looking for the lowest side of the triangle. So to figure this out we use tangent, tangent is equal to Opposite over adjacent. So the tangent(37)= bear from base/height of cliff. We then multiply tan(37) by 400 to get the answer
Which shapes make up this composite figure?
a cylinder and a cone
a cylinder and two cones
a half sphere, a cylinder, and a cone
a sphere and a cylinder
Answer: a sphere and a cylinder
Step-by-step explanation:
The composite figure has two semi-circles on each end (which is basically a whole sphere). In the middle is a cylinder. So, d is the correct option.
A cone has a triangular form, so it can't be the other answers.

Answer:
It's 76 degrees
Step-by-step explanation:
Thanks for branliest
Answer:
76
Step-by-step explanation:
the interior angles of a triangle always add up to 180 degrees, so all we have to do is add the 2 angle values that we know, so 48 + 56=104, then we subtract that from 180 to get 76. Hope this helps!

Let f(-x) = 5x – 2 and g(x) = 2x + 3 and find f(x) –
f(0) — 9(x) = 7x – 1
f(.2) – 9(x) = 7x + 1
f(x) — 9(2) = 3x – 5
f(x) – 9(x) = -3x +5
Answer:
3x - 5
Step-by-step explanation:
Given that f(x) = 5x - 2 and g(x) = 2x+3
f(x) - g(x) = 5x-2 - (2x+3)
Expand
f(x) - g(x) = 5x - 2 - 2x - 3
Collect like terms
f(x) - g(x) = 5x - 2x -2-3
f(x) - g(x) = 3x - 5
Hence the required answer is 3x - 5

Given:
In a parallelogram [tex]PRTV, VQ\perp PR,VS\perp RT[/tex].
To prove:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Solution:
It is given that [tex]VQ\perp PR,VS\perp RT[/tex], it means [tex]\angle PQV[/tex] and [tex]\angle TSV[/tex] are right angle triangles.
In triangle PQV and triangle TSV,
[tex]\angle PQV\cong \angle TSV[/tex] (Right angles)
[tex]\angle QPV\cong \angle STV[/tex] (Opposite angles of a parallelogram)
Two corresponding angles are congruent. So, by AA property of similarity, we get
[tex]\Delta PQV\sim \Delta TSV[/tex]
We know that the corresponding parts of similar triangles are proportional. So,
[tex]\dfrac{PQ}{TS}=\dfrac{PV}{TV}[/tex]
It can be rewritten as:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Hence proved.
What is the intermediate step in the form (x+a)^2=b(x+a)
2
=b as a result of completing the square for the following equation?
6x^2+48x+207=15
Answer:
The intermediate step are;
1) Separate the constants from the terms in x² and x
2) Divide the equation by the coefficient of x²
3) Add the constants that makes the expression in x² and x a perfect square and factorize the expression
Step-by-step explanation:
The function given in the question is 6·x² + 48·x + 207 = 15
The intermediate steps in the to express the given function in the form (x + a)² = b are found as follows;
6·x² + 48·x + 207 = 15
We get
1) Subtract 207 from both sides gives 6·x² + 48·x = 15 - 207 = -192
6·x² + 48·x = -192
2) Dividing by 6 x² + 8·x = -32
3) Add the constant that completes the square to both sides
x² + 8·x + 16 = -32 +16 = -16
x² + 8·x + 16 = -16
4) Factorize (x + 4)² = -16
5) Compare (x + 4)² = -16 which is in the form (x + a)² = b

how do i find the diameter of a circle with only knowing the area?
Answer:
2 * (Area/pi)^(1/2) = diameter
Step-by-step explanation:
The equation for the area of a circle is A = pi * r^2
We can divide both sides by pi to get:
A/pi = r^2
Then take the square root of both sides to get:
(A/pi)^(1/2) = r
Then, since D = 2 * r, we can multiply both sides of the above equation by 2 to get:
2 * (A/pi)^(1/2) = 2 * r = D
Answer:
d=2[tex]\sqrt{a/\pi }[/tex]

Como hago para calcular el porcentaje de unos datos agrupados , porfa ayuda no entiendo. osea tipo : tengo que calcular cual es el porcentaje de personas que trabajan que tienen esta edad 31-46 y pues nose si colocar 3%-4% ay no se estoy perdida porfa si entienden lo q trato de decir me ayudaria resto
Answer:
Falta información para darte una respuesta exacta, así que voy a dar una explicación general de este tipo de problemas.
Querés saber cuál es el porcentaje de personas que trabajan y están en el rango de edades entre 31 y 46.
Entonces lo primero que tenemos que hacer es encontrar el número total de personas que trabajan, digamos que es T (esto es el 100%)
Luego hay que encontrar el número total de personas que trabajan y tienen entre 31 y 46, digamos que es N.
Podemos relacionar estas cantidades con porcentajes de la siguiente manera:
N = P
T = 100%
Donde P es el porcentaje que queremos calcular.
Si tomamos el cociente de esas dos ecuaciones, obtenemos:
N/T = P/100%
Resolviendo para P obtenemos:
(N/T)*100% = P
El porcentaje de personas que trabajan y tienen entre 31 y 46 va a ser entonces:
P = (N/T)*100%
Así sabiendo el número total de personas que trabajan y el número de personas que trabajan y además tienen edades entre 31 y 46, podemos calcular el porcentaje que queremos.
Particularmente decis que no sabes si colocar 3% o 4%.
Lo que podria implicar que tambien quizas tengas un problema de redondeo.
Si tenes un numero como:
3.a%
donde a es un digito entre 0 y 9
si a es menor que 5, entonces redondeamos para abajo, y asi obtenemos:
3.a% = 3%
si a es igual a 5 o mayor, redondeamos para arriba, asi obteniendo:
3.a% = 4%.
The salary of college professors from more than 25,000 universities and colleges in USA is normally distributed with a mean, $85,900 and its standard deviation, $11,000. If you collect a random sample from 35 professors, find the probability that the sample mean is between $70,000 and $100,000?
Answer:
The answer is below
Step-by-step explanation:
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by the formula:
[tex]z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mean,\ \sigma=standard\ deviation.\\\\For \ a\ sample\ size(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }[/tex]
Therefore given that μ = $85900, σ = $11000, n = 35.
For x > 70000:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{70000-85900}{11000/\sqrt{35} } =-8.55\\[/tex]
For x < 100000
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{100000-85900}{11000/\sqrt{35} } =7.58[/tex]
From the normal distribution table, P(70000< x < 100000) = P(-8.55 < z < 7.58) = P(z < 7.58) - P(z < -8.55) = 1 - 0 = 1 = 100%
