Una moto A consume 8,2 litros de gasolina por cada 100km y otra moto B 8,9 litros de gasolina también por cada 100km. Calcula la gasolina que consume una moto en 1 km
Respuesta:
Motocicleta A = 0.082 litros por km
Motocicleta B = 0.089 litros por km
Explicación paso a paso:
Dado :
Consumo de gasolina de la motocicleta A y la motocicleta B por 100 km
Motocicleta A = 8.2 litros
Motocicleta B = 8,9 litros
Consumo por kilómetro:
Litros consumidos por 100 km / 100 km
Motocicleta A:
8.2 / 100 km
= 0,082 litros por km
Motocicleta B:
8,9 / 100 km
= 0,089 litros por km
A circle is graphed on a coordinate grid and then reflected across the y axis. if the center of the original circle was located at (x,y), which ordered pair represents the center of the new circle after the transformation?
Answer:
(-x,y)
Step-by-step explanation:
If it's positive and you flip it accross the y-axis, the x- coordinates become negative.
Find the values of the measures shown when each value in the data set increases by 25. Mean: 109 Median: 104 Mode: 96 Range: 45 Standard deviation: 3.6
Answer:
The new values are as follows:
Mean: 134
Median: 129
Mode: 121
Range=45
Standard Deviation=3.6
Step-by-step explanation:
When a k real number is added to all the elements of the dataset, the new measures of center (mean, median, and mode) are simply found by adding the value k to the previous values. Thus
[tex]Mean_{new}=Mean_{old}+k[/tex]
Here [tex]Mean_{old}[/tex] is 109 and k is 25 thus
[tex]Mean_{new}=Mean_{old}+k\\Mean_{new}=109+25\\Mean_{new}=134[/tex]
Similarly
[tex]Median_{new}=Median_{old}+k[/tex]
Here [tex]Median_{old}[/tex] is 104 and k is 25 thus
[tex]Median_{new}=Median_{old}+k\\Median_{new}=104+25\\Median_{new}=129[/tex]
Also
[tex]Mode_{new}=Mode_{old}+k[/tex]
Here [tex]Mode_{old}[/tex] is 96 and k is 25 thus
[tex]Mode_{new}=Mode_{old}+k\\Mode_{new}=96+25\\Mode_{new}=121[/tex]
When a k real number is added to all the elements of the dataset, the new measures of variation (range and standard deviation) remain the same thus.
[tex]Range_{new}=Range_{old}\\Range_{new}=45[/tex]
Similarly
[tex]Standard\ Deviation_{new}=Standard\ Deviation_{old}\\Standard\ Deviation_{new}=3.6[/tex]
So the new values of mean, median, mode, range, and standard deviation are 134, 129, 121, 45, and 3.6 respectively.
Which of the following is the equation of a line that has a slope of -2 and passes through the
point (1,6)?
A.y=x+6
B.y=-2x+8
C.y=-2x+4
D.y=1/2x+4
Answer:
B. y = -2x + 8
Step-by-step explanation:
So the slope is the number that comes before the x, and if the slope is -2, that means the number before is -2, and it is.
And to know if it goes through (1, 6), put those numbers into the equation and see if they match up (x is the y-intercept)
6 = -2(1) + x
6 = -2 + x
x = 8
The one with both of these is B, which means B is the answer
what is the y and m and c in 2x + y = 1

At a football game, a vender sold a combined total of 181 sodas and hot dogs. The number of hot dogs sold was 51 less than the number of sodas sold. Find the
number of sodas sold and the number of hot dogs sold.
Answer: Number of hot dogs sold = 65
number of soda sold = 116.
Step-by-step explanation:
Let the number of hot dogs sold be represented by x.
Since the number of hot dogs sold was 51 less than the number of sodas sold, then the number of soda sold will be: = x + 51
Since the addition of both hot dogs and soda equals 181, we can form this into an equation which will be:
= x + (x + 51) = 181
x + x + 51 = 181
2x + 51 = 181
2x = 181 - 51
2x = 130
x = 130/2
x = 65
Number of hot dogs sold = 65
Since number of soda sold equals:
= x + 51
= 65 + 51
= 116
Therefore, number of soda sold is 116.

Suppose you have a bag of colored plastic disks and you choose one without looking. The probability the disk you choose is is P() . Write this probability as a decimal. Use a word or phrase to describe this probability.
Question:
Suppose you have a bag of colored plastic disks, and you choose one without looking. The probability the disk you choose is yellow is P(yellow)=5/25.
Write this probability as a decimal.
Use a word or phase to describe this probability
Answer:
[tex]P(yellow)=0.2[/tex]
Unlikely event
Step-by-step explanation:
Given
[tex]P(yellow)=\frac{5}{25}[/tex]
Solving (a): Express as decimal
[tex]P(yellow)=\frac{5}{25}[/tex]
As decimal, we have:
[tex]P(yellow)=0.2[/tex]
Solving (b): Description
Since the probability is closer to 0 than 1, we can say that the probability of picking a yellow is unlikely

The coordinates of point are (7, 4). Point is a reflection of point across the x-axis. In which quadrant will point W be located
Answer:
Point W will be located on the bottom right quadrant.
Step-by-step explanation:
The x variable becomes negative when reflected across the x-axis.
Answer:
The reflected point will be on the 4th qudrant.
Step-by-step explanation:
So, lets remember what each qudrant is. The first one is (+, +).
The secodn one is (+, -)
The third one is (-,+)
And the fourth one is (-,-)
So looking at this, we instantly know that the orginal point is on qudrant 1. Since our number is +7, +4.
Now we have to flip around the x axis. Well, to the left of the quadrant 1 is qudrant 2. To the bottom of qudrant 1 is qudrant 4. We clearly cannot go to the top or right since there arent any more quadrants, and the qudrant 3 is not accesable with our x and y values.
Remember. we arent going left, since that would be crossing the y axis. This means we have to go down, to the bottom.
What is below qudrrant 1? As I said above, that would be quadrant 4.
Answer:
Quadrant 4
Hope this helps!

Answer:
6. The common mistake is believing that the 3/4 money is remaining.
Step-by-step explanation:
Since Xander spent 3/4 of the money, you would need to multily 24 dollars by 3/4 and find amount spent. This would be 18. Then subtract 24 -18 to get an answer of $6

Martha rolls a 6 sided number cube two times.
What is the probability that she will roll a prime number both times.
Answer:
25% chance
Step-by-step explanation:
There are 3 prime numbers on a 6-sided die so that means there is a 1/2 chance you roll a prime number. In order to calculate the probability of 2 or more events you multiply their probability which would be
1/2 * 1/2 = 1/4
So the chance of rolling a prime number on both rolls is a 1/4 chance or a 25% chance
The probability that she will roll a prime number both times is 0.25.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Martha rolls a 6 sided number cube two times.
And the prime numbers in the cubes are {2, 3, 5}.
The probability that she will roll a prime number both times,
= 3/6 x 3/6
= 1/2 x 1/2
= 1/4
= 0.25
Therefore, 0.25 is the probability.

Use your understandinh of rational functiosn to answer the followinh wuestions about the relationship of concert profit
Question:
Use your understanding of rational functions to answer the following question about the relationship of concert profit P(x)=-25x^2+875x-4750 to concert operating expenses c(x)=4750-125x.
Write an algebraic rule for the function T(x), which gives the ratio of profit to operating expenses, that is, the number of dollars earned for every dollar spent by the concert promoters.
Answer:
[tex]T(x) = \frac{x^2-35x+190}{5x-190}[/tex]
Step-by-step explanation:
Given
[tex]P(x)=-25x^2+875x-4750[/tex] --- concert profit
[tex]c(x)=4750-125x.[/tex] --- concert operating exercise
Solving (a): An expression for T(x)
T(x) is the ratio of P(x) to c(x)
So:
[tex]T(x) = \frac{P(x)}{c(x)}[/tex]
[tex]T(x) = \frac{-25x^2+875x-4750}{4750-125x}[/tex]
Factorize
[tex]T(x) = \frac{-25(x^2-35x+190)}{-25(-190+5x)}[/tex]
[tex]T(x) = \frac{x^2-35x+190}{-190+5x}[/tex]
Rewrite as:
[tex]T(x) = \frac{x^2-35x+190}{5x-190}[/tex]
