Answer:
Cantidad que Lupe dejó en casa con inicialmente = 127.5 soles.
Amount that Lupe left home with initially = 127.5 soles.
Step-by-step explanation:
Pregunta correcta
Lupe va al mercado y compra abarrotes con los 2/5 de su dinero ; luego va a la seccion de carnes y compra con los 1/3 de lo que le queda ; si gasta 3 soles en pasaje de ida y vuelta ; ¿con cuanto dinero salio de su casa si llega de regreso a su casa con 48 soles?
Solución
Deje que la cantidad de dinero que Lupe dejó en casa sea x soles.
Lupe compra comestibles con 2/5 de su dinero. Es decir, Lupe gasta (2/5) × x = (2x/5)
En este punto, Lupe se queda con
x - (2x/5) = (3x/5) soles.
Lupe luego gasta 1/3 de lo que queda en la carne
(1/3) de lo que queda = (1/3) × (3x/5) = (x/5)
Lo que significa que Lupe gasta (x/5) soles en la sección de carne.
Cantidad restante después de la sección de carne = (3x/5) - (x/5) = (2x/5)
Lupe gasta 3 soles en el viaje de ida y vuelta al mercado y se queda con 47 soles después de todo.
(2x/5) - 3 = 48
(2x/5) = 48 + 3 = 51
2x = 5 × 51 = 255
2x = 255
x = (255/2) = 127.5 soles
¡¡¡Espero que esto ayude!!!
English Translation
Lupe goes to the market and buys groceries with 2/5 of her money; then he goes to the meat section and buys with 1/3 of what he has left; if you spend 3 soles on a round trip ticket; How much money did you leave your home with if you arrive home with 48 soles?
Solution
Let the amount of money Lupe left home with be x soles.
Lupe buys groceries with 2/5 of her money
That is, Lupe spends (2/5) × x = (2x/5)
At this point, Lupe is left with
x - (2x/5) = (3x/5) soles.
Lupe then spends 1/3 of what is left on meat
(1/3) of what is left = (1/3) × (3x/5) = (x/5)
Meaning that Lupe spends (x/5) soles at the meat section.
Amount left after the meat section = (3x/5) - (x/5) = (2x/5)
Lupe spends 3 soles on round ticket trip to market and is left with 47 soles after everything.
(2x/5) - 3 = 48
(2x/5) = 48 + 3 = 51
2x = 5 × 51 = 255
2x = 255
x = (255/2) = 127.5 soles

Jennifer wants to see if the color of the testing room causes test anxiety. She asks 100 participants to come to a modified classroom, and as they walk in, she asks each person to choose either a testing cubicle painted bright red or a testing cubicle painted off white. On the basis of their choices, participants spend 20 minutes in one or the other cubicle solving challenging math problems. Then, they complete a survey asking them questions about how anxious they were during the math test. What's wrong with Jennifer's experiment?
Answer: Jennifer didn't randomly assign participants to the control and experimental group.
Step-by-step explanation: In the scenario discussed above, Jennifer failed to perform a random assignment of the participants who took part in the survey, that is the experimental group, those who receive the treatment and the control group, those who don't. Random assignment is required in other to address the issue of bias in our experiment. She was supposed to perform a random assignment of the participants to the two groups instead of asking them to make a choice.

If the measure of a tangent-chord angle is 68°, then what is the measure of the intercepted arc inside the angle?
Answer:
113°,
Step-by-step explanation:
tangent - chord angle is 68°,Answer:
112°
Step-by-step explanation:
1/2(248 - 112) = 68
2 equations with 2 unknowns
x = intercepted arc, y = rest of the circle
x + y = 360
1/2 (y - x) = 68
1/2 ((360 - x) - x) =68
360 - 2x = 136
224 = 2x
112 = x

Three bells toll at an interval of 4,5 and 6 second .after how much time will they toll together
Answer:
after 60 seconds = 1 minute ,they will together for the first time.
Step-by-step explanation:
Three bells toll at an interval of 4,5 and 6 second.
They will ring together at the time which will be the multiple of all the three time interval (i.e 4,5,6)
4 = 2*2
5= 5*1
6 = 2*3
LCM of these three number will be multiple of highest power of each prime number
highest power of 2 in the above problem 2^2
3 = 3
5 = 5
Thus, LCM 2^2 * 3*5 = 60
Thus, after 60 seconds they will together for the first time.
Then they will toll together after each interval of 60 seconds together.

Solve sin 20 = COS CE-30)
Answer:
CE = 100°
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Given x = 20°, then 90° - 20° = 70° thus
CE - 30 = 70° ( add 30 to both sides )
CE = 100°
Thus
sin20° = cos(100 - 30)° = cos70°
Answer:
CE = 100

A shopkeeper sold an article at 20 % discount and made a loss of Rs 90. If he had
sold it at 5 % discount, he would have gained Rs 90. Find the cost price and the
marked price of the article.
Answer:
The cost price of the article is Rs 1050
The marked price of the article Rs 1200
Step-by-step explanation:
The given discount on the article = 20%
The amount loss = Rs 90
With a discount of 5% the amount gained = Rs 90
Let the cost price of the article = X
Let the marked price of the article = Y
Therefore, we have;
(1 - 0.2) × Y = X - Rs 90
(1 - 0.5) × Y = X + Rs 90
Which gives;
0.8·Y = X - Rs 90 .......................(1)
0.95·Y = X + Rs 90.....................(2)
Subtracting equation (1) from equation (2), we have;
0.95·Y-0.8·Y = X + Rs 90 - (X - Rs 90) = X - X + Rs 90 + Rs 90 = Rs 180
0.15·Y = Rs 180
Y = Rs 180/0.15 = Rs 1200
Therefor, the marked price of the article = Rs 1200
From;
0.8·Y = X - Rs 90, we have;
0.8×Rs 1200 = X - Rs 90
X = 0.8× 1200 + 90 = Rs 1050
Therefore, the cost price of the article = Rs 1050.

Gwen participates in an online rewards program.She earns points for completing surveys. Gwen earns 10 points for each survey she completes,and she wants to predict the total number of points that she will earn based on the number of surveys that she completes. Which quantities in this situation have more than one possible value? Choose All That apply.
The number of surveys Gwen completes.
The number of points Gwen earns for completing each survey.
The total number of points Gwen earns.
Answer:
Step-by-step explanation:
Hello,
For each survey that Gwen completes she earns 10 points.
So the number of points Gwen earns for completing each survey is 10 and there is only one value.
If x is the number of surveys Gwen completed, her number of points is 10 multiplied by x.
The number of surveys Gwen completes can have several values.
And then, the total number of points Gwen earns can have several values too.
So you need to choose
The number of surveys Gwen completes.
and
The total number of points Gwen earns.
Hope this helps.

which set of steps will translate f(x)=6x to g(x)=6x-5-7
THIS IS THE COMPLETE QUESTION BELOW;
Which set of steps will translate f(x) = 6x to g(x) = 6x – 5 – 7?
Shift f(x) = 6x five units to the left and seven units up.
Shift f(x) = 6x five units to the right and seven units down.
Shift f(x) = 6x seven units to the right and five units up.
Shift f(x) = 6x seven units to the left and five units down.
Answer:
Shift f(x)=6x five units to the left and seven units down.
Step-by-step explanation:
We are told to translate the function below
f(x) = 6x to g(x) = 6x – 5 – 7
Which means the process to translate f(x) into g(x) is required.
According to the translation rule
f(x)-------->f(x)+a
If a<0 it shift to downward
If a>0 it shift to upward
Then we have
(X,y) ----->((x - 5, y)
There is a shift by x coordinates towards left by 5 units
then we would have the function as
f'(x) = 6(x-5)
Following the translation rule there is a shift by the function by 7 units downward direction then we have
(x,y) ----->(x,y -7)
Then we have g(x) = 6x – 5 – 7 as our translation product.
Therefore, shift f(x)=6x five units to the left and seven units down.

Determine what type of model best fits the given situation:
A model rocket fired straight up from the ground, where h is the height of the rocket and t is the time in seconds.
Answer:
Ok, i will suppose the situation that:
The rocket has a constant speed S (So the acceleration of the rocket is equal in magnitude, but opposite in direction, to the gravitational acceleration)
Here we can remember that:
Velocity = distance/time.
Then if the distance is the height of the rocket, we can write this as:
H = velocity*time
h = S*t
This is a linear model that represents the height of the rocket as a function of time.
Case 2:
The rocket is fired with an initial velocity v0, but no acceleration:
In this case the only acceleration acting on the rocket is the gravitatonal acceleration pulling the rocket down, so the acceleration is:
a = -g
To get the velocity as a function of time, we should integrate:
a = -g*t + v0
To get the height as a function of time, we integrate again:
h(t) = (-g/2)*t^2 + v0*t + p0
Where p0 is the initial position of te rocket, but the rocket starts at the ground, so p0 = 0m.
The height as a function of time is:
h(t) = (-g/2)*t^2 + v0*t
This is a quadratic equation.
