Answer:
66%
Step-by-step explanation:
To find the percentage, we can use this formula:
Part/Whole
In this case, the Part=Seniors and Whole=All of the students in the class
Part/Whole
23/(23+12)
=23/35
=0.65714
=0.66
=66%
.¿Cuál de las siguientes alternativas no corresponde a una transformación isométrica? A)Traslación B) Simetría C) Rotación D) Isometría C) Teselación
Answer:
D) Isometría
Step-by-step explanation:
Hola, D es la respuesta correcta porque la isometría no es una transformación isométrica, veamos por qué.
Una Transformación Isométrica es el cambio de forma, pero no por tamaño ni forma de la figura.
A. La traslación es una transformación isométrica porque desliza la figura a otro lugar, sin afectar su forma o tamaño.
B. La simetría es una transformación isométrica porque técnicamente es un reflejo, una vez más no afecta el tamaño o la forma de la figura.
C. La rotación es una transformación isométrica porque gira la figura, sin afectar el tamaño o la forma de la figura.
E. La teselación es una transformación isométrica porque une la misma forma, sin afectar el tamaño o la forma de la figura.
Dejándonos con D.

The amount of money, in dollars, John earns for each shift he works at the bookstore is equal to the function ƒ(h) = 10h, where h is the number of hours he works during his shift. Enter the value for ƒ(h), the amount of money he earns for his shift, and the value for h, the number of hours he works during his shift, for each notation in order to complete the table and show the relationship between ƒ(h) and h.
Answer:
Step-by-step explanation:
Amount of money earned by John for each shift he works at the bookstore is represented by the function,
f(h) = 10h
Where f(h) = Amount of money earned in dollars
h = number of hours worked by John
1). For h = 1 hour
f(1) = 10 × 1
= $10
2). For h = 2.5 hours
f(4.5) = 10 × 4.5
= $45
3). For h = 10 hours
f(10) = 10 × 10
= $100
One country has 12 stone bridges and 20 steel bridges. What is the ratio of ? A. Stone bridges to steel bridges. B. Steel bridges to stone bridges. C total bridges to steel bridges.

6 : 10
3 : 5
answer = 3 : 5
B. Steel bridges to Stone bridges
20 : 12
10 : 6
5 : 3
answer = 5 : 3
Total bridges = 20+12=32
C. Total bridges to steel bridges
32 : 20
16 : 10
8 : 5
answer = 8 : 5
Answer:
A (Stone to Steel bridges)= 3:5
B (Steel to Stone bridges)= 5:3
C (Total bridges to steel bridges)= 8:5
Step-by-step explanation:
A: Stone to steel bridges is
12:20
You can simplify that by dividing by 4 on both numbers:
3:5
So the ratio of stone to steel bridges is 3:5
B: Steel to stone bridges is
20:12
You can simplify that by dividing by 4 on both numbers:
5:3
So the ratio of stone to steel bridges is 5:3
C: Total bridges to steel bridges is
What is the total number of bridges?
20+12=32
32:20
You can simplify that by dividing 4 on both numbers:
8:5
So the ratio of the total number of bridges to steel bridges is 8:5

Solve c= 8a-3b for a
Answer:
(c+3b)/8 = a
Step-by-step explanation:
c= 8a-3b
Add 3b to each side
c+3b= 8a-3b+3b
c+3b = 8a
Divide each side by 8
(c+3b)/8 = 8a/8
(c+3b)/8 = a

Answer:
Option (B)
Step-by-step explanation:
[tex]\begin{bmatrix}4 & 0\\ -1 & 2\\ -3 & -1\end{bmatrix}\times\begin{bmatrix}0 & 1 \\ -3 & 1\end{bmatrix}[/tex]
In the multiplication of two matrices we multiply the column of 1st matrix with the row of the 2nd matrix and add them.
= [tex]\begin{bmatrix}(4\times 0)+0(-3) &(4)1+0(1)\\ (-1)0+2(-3) &(-1)1+2(1)\\ (-3)0+(-1)(-3) &(-3)1+(-1)1 \end{bmatrix}[/tex]
= [tex]\begin{bmatrix}0 &4\\ -6 &1\\ 3 &-4 \end{bmatrix}[/tex]
Therefore, Option (B) will be the answer.
Select all the lines below that are an asymptote to the rational function of f(x)= 2x+1/x-9. Picture attached, 15 points and I'll give Brainliest! Due in two hours.
Answer:
Solution : Option A and Option C
Step-by-step explanation:
To determine our vertical asymptote here we can make the denominator of the rational function equivalent to zero ...
x - 9 = 0,
x = 9 - this is our vertical asymptote
Now there are three rules that we need to apply when determining the horizontal asymptote. To do so we take the degree of each " x " term and compare the numerator and denominator degree.
If the numerator (degree) < denominator (degree), we take the degree of the numerator as the asymptote --- (1). If the numerator (degree) = denominator (degree) we take the coefficient of the x terms, and divide --- (2). If the numerator (degree) > denominator (degree) their will be no asymptote.
In this case our degree for the numerator is 1, (x¹) and our degree for the denominator is the same, 1 (x¹). Therefore we divide the coefficients, 2 / 1 = 2. Our horizontal asymptote is y = 2.

13=-4k+9 someone solve pls
Answer:
k = - 1
Step-by-step explanation:
13 = -4k + 9
-4k + 9 = 13
subtract 9 from both sides
-4k + 9 - 9 = 13 - 9
simplify
-4k = 4
k = 4 / -4
k = - 1

En un entrenamiento, Mariana metió 12 de los 15 tiros al arco que pateo. Carla tuvo una efectividad del 75%. Cual de las dos chicas tuvo un mejor desempeño al pasear al arco?
Answer:
Mariana has better performance.
Step-by-step explanation:
We are given that in a training session, Mariana made 12 of the 15 shots on goal that she kicked and Carla had an effectiveness of 75%.
And we have to find which girl's performance is better.
Since it is stated that Carla had an effectiveness of 75%.
Similarly, we will find the effectiveness of Mariana;
Total shots available to Mariana = 15 shots
Number of shots on goal = 12
So, her effectiveness = [tex]\frac{12}{15} \times 100[/tex]
= [tex]4 \times 20[/tex] = 80%
This shows that Mariana has a better performance as compared to Carla as 80% > 75%.
7. Bruno noticed today's gasoline price at the local convenience store was advertised as $3.40 per gallon. This price is 15% above last year's price. Calculate last year's price. $ 3.55 O $ 3.25 O $ 2.96 O $ 2.40
Answer:
I'm pretty sure it $2.96
Answer:
option c) $ 2.96
Step-by-step explanation:
15% = 15 /100 = 0.15
Let last year's price = $ x
x + 15% of x = $ 3.40
x + 0.15*x = 3.40
x + 0.15x = 3.40 {Add like terms}
1.15x = 3.40 {Divide both sides by 1.15}
1.15x/1.15=3.40/1.15
x = 2.956
Last year's price = $ 2.96

The middle note C has a frequency of 262 hertz and can be modeled using a sine function with an amplitude of 1.5, where x is time in seconds. Which function represents the vibrations of this note?
Answer: f(x) = 1.5*sin(x*2*pi/0.0038s)
Step-by-step explanation:
A sine function is:
f(x) = A*sin(c*x + f)
Where A is the amplitude, we know that it is 1.5
c is a constant that depends on the frequency.
f is a phase.
As there is no mention of a phase, we can assume f = 0.
Then our function is:
f(x) = 1.5*sin(c*x)
now let's find the value of c.
We know that the frequency is 262hz.
Then the period can be calculated with the equation:
T = 1/f.
T = 1/262 Hz = 0.0038 seconds.
Now, the period of a sin function is 2*pi.
whit pi = 3.14159265358979.....
Then we have that:
sin(0) = sin(c*0.0038s)
sin(0) = sin(2*pi)
then:
c*0.0038s = 2*pi
c = 2*pi/0.0038s
Then the function is:
f(x) = 1.5*sin(x* 2*pi/0.0038s)
According to the information given, the sine function is:
[tex]y = 1.5\sin{(524\pi x)}[/tex]
The standard sine function is given by:
[tex]y = A\sin{(2\pi fx)}[/tex]
In which:
A is the amplitude.f is the frequency, in Hz.In this problem:
Amplitude of 1.5, hence [tex]A = 1.5[/tex]Frequency of 262 Hz, hence [tex]f = 262[/tex]Then, the equation is:
[tex]y = A\sin{(2\pi fx)}[/tex]
[tex]y = 1.5\sin{(2\pi (262)x)}[/tex]
[tex]y = 1.5\sin{(524\pi x)}[/tex]
A similar problem, which also involves building a sine function according to the desired characteristics, is given at https://brainly.com/question/18055768
