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

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.
Answer:
A. Stone bridges to steel bridges=
12 : 20
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

A circular room has a floor of diameter 590cm. Estimate the 92.2 perimeter of the room in metres
Answer:
18.5 m
Step-by-step explanation:
The diameter in meters is 5.90, so the circumference of the room is ...
C = πd = 5.90π m ≈ 18.5 m
The perimeter of the room is about 18.5 m.
Here’s the picture for it
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.

.¿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.

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
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

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%.

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

What value of x is in the solution set of 2(3x – 1) ≥ 4x – 6?
–10
–5
–3
–1
Answer: -1
Step-by-step explanation:
Given by your question
2(3x-1)≥4x-6
Distributive property to take off the parentheses
2×3x-2×1≥4x-6
6x-2≥4x-6
Subtract 4x on both sides (Subtractive property of equality)
6x-2-4x≥4x-6-4x
2x-2≥-6
Add 2 on both sides (Addition property of equality)
2x-2+2≥-6+2
2x≥-4
Divide 2 on both sides (Division property of equality)
2/2 x≥-4/2
x≥-2
