Un barril de petróleo equivale a 159 litros entonces si un pozo de petróleo produce 374 barriles por minuto. ¿Cuántos litros son? * 10 puntos A) 2.35 B) 4.80 C) 59 466 D) 128 345
Answer:
374 barriles equivalen a 59466 litros de petróleo.
Step-by-step explanation:
La regla de tres simple es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos. Es decir, lo que se pretende es encontrar el cuarto término de una proporción conociendo los otros tres. Recuerde que la proporcionalidad es una relación o razón constante entre diferentes magnitudes.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, también lo hace la otra (o cuando una magnitud disminuye, también lo hace la otra), se debe aplicar la regla directa de tres. Para resolver una regla directa de tres, se debe aplicar:
a ⇒ b
c ⇒ x
donde a, b y c son valores conocidos, mientras x es el valor que se desea conocer. Entonces: [tex]x=\frac{c*b}{a}[/tex]
En este caso, la regla de tres se aplica de la siguiente manera: si 1 barril de petróleo equivale a 159 litros, 374 barriles a cuántos litros equivale?
1 barril ⇒ 159 litros
374 barriles ⇒ x litros
[tex]cantidad de litros =\frac{374 barriles*159 litros}{1 barril}[/tex]
cantidad de litros= 59466 litros
374 barriles equivalen a 59466 litros de petróleo.

[tex]x^{2} +9y^{2} =1[/tex] is an ellipse. The line y=mx+2 is tangent to the ellipse. Determine the value of ([tex]m^{2}[/tex]). Express your answer as an integer or as a common or improper fraction.
9514 1404 393
Answer:
m^2 = 35/9
Step-by-step explanation:
The line will be tangent to the ellipse where there is one point of intersection between the line and the ellipse. We can find that case by looking at the discriminant of the quadratic.
x^2 +9(mx +2)^2 = 1
x^2 +9(m^2x^2 +4mx +4) = 1
(9m^2 +1)x^2+36mx +35 = 0 . . . . subtract 1, collect terms
__
Then the discriminant is ...
(36m)^2 -4(9m^2 +1)(35)
We want it to be zero, so we have ...
1296m^2 -1260m^2 -140 = 0 . . . . eliminate parentheses
36m^2 = 140 . . . . . . . . . . . . . . . add 140
m^2 = 140/36 . . . . . . . . . . . . divide by 36
m^2 = 35/9

Answer:
Assuming the shape is a half-circle, there's two right angles.
Step-by-step explanation:
The angle between the straight segment and the half-circle can be measured by taking a tangent line at the intersection point and it will of course be perpendicular to the straight segment, assuming the segment is the diameter of the circle).
6a+4b−66, a, plus, 4, b, minus, 6 when a=1a=1a, equals, 1 and b=3b=3b, equals, 3.
Answer:
The answer is 12.
Step-by-step explanation:
We need to find the value of the given expression 6a+4b−6 when a = 1 and b = 3
Put a = 1 and b = 3 in the above expression.
6a+4b−6 = 6(1) +4(3) -6
= 6+12-6
= 12
So, the value of the given expression is equal to 12.

the number of soda bottles the machine can make
each minute.

Time (minutes)
Answer:
The number of soda battles the machine can make per minute is 40
Step-by-step explanation:
What we simply want to do here is to use the two marked points to get the number of soda bottles made per minute
Mathematically, what we have to do here is to
use the two point slope equation
we have this as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (3,120
(x2,y2) = (5,200)
m = (200-120)/(5-3) = 80/2 = 40

Step-by-step explanation:
State the domain for the following relation.{(4, -1), (3, 2), (0, -3), (1, 4)} *
A. {0, 1, 3, 4}
C. {0, 1, 2, 4}
B. {2, 3, 4, 5}
D. {0, 1, 3, 5}
Answer:
A. {0, 1, 3, 4}
Step-by-step explanation:
For a relation with elements (x, y)
The domain is the set of the x-values, that are the input values.
Here we have the relation:
{(4, -1), (3, 2), (0, -3), (1, 4)}
Here we can see that the inputs are:
4, 3, 0, and 1.
Then the domain is:
{4, 3, 0, 1}
Now let's write this in the correct order:
{0, 1, 3, 4}
The domain of the relation is: {0, 1, 3, 4}
Then the correct option is A.
What is the median of the data set? 15, 19, 20, 22, 26, 30, 31
O A. 15
O B. 31
O c. 22
O D. 7.
Answer:
C. 22
Step-by-step explanation:
The median is the middle number of the set if the numbers are in order from least to greatest.
This set of numbers is in order, so the median is the middle number = 22

The equation for this is G= -3/2x + 12
and the interpretation of the context, I may get this wrong, is the Y-intercept is the number of gallons used per mile
Step-by-step explanation:
to find out the slope, you get the point from the y-intercept (0, 12) and you see how much you go down for the first number, then you see how much you go right for the second number until you reach the next point in which case it's (2, 9), which will give you 3 for the first number and 2 for the second number.
Then you place the first number above the second number and put a negative sign in front of the whole thing if the line is going down. So the number would be 3/2 and the line is going down, so the answer would be -3/2
to find the y-intercept, you just look at where the point starts on the y-intercept, which is at 12. So the y-intercept is 12.

Ms. Placencio weighed 153 pounds in 2018. Ms. Placencio now weighs 132 pounds. What is the percent change? Round to the nearest tenths place.
Answer:
13.73°
Step-by-step explanation:
For this question, you can set it up so you can cross multiply.
[tex]\frac{153}{100}[/tex]°×[tex]\frac{132}{?}[/tex]
To find the ? (the percent of change), simply multiply 100 and 132, then divide the result by 153.
You get around 86.27 when rounded to the nearest tenths.
However, this percent represents 132 within 153, so find the percent of change, simply subtract 86.27 from 100.
100-86.27= 13.73

Answer:
1) We know that e is an irrational number, so we usually can find it by computational methods.
[tex]e = \lim_{n \to \infty} (1 + \frac{1}{n})^n[/tex]
and we know that e accurate to 10 decimal points is:
e = 2.7182818285
2) Now we want to write the properties of the exponential and logarithmic functions.
We will write first the exponential property, and then the correspondent one for the logarithmic function.
(e^a)*(e^b) = e^(a + b)
The equivalent Ln property is:
Ln(a) + Ln(b) = Ln(a*b)
(e^a)/(e^b) = e^(a - b)
The eqivalent Ln property is:
Ln(a) - Ln(b) = Ln(a/b)
(e^a)^b = e^(a*b)
The equivalent Ln property is:
Ln(a^b) = b*Ln(a)
