Answer:
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
Step-by-step explanation:
Recordamos que la densidad de un material uniforme ([tex]\rho[/tex]), medido en kilogramos por metro cúbico, está definido por:
[tex]\rho = \frac{m}{V}[/tex] (1)
Donde:
[tex]m[/tex] - Masa, medido en kilogramos.
[tex]V[/tex] - Volumen, medido en metros cúbicos.
Ahora calculamos la densidad de cada recipiente:
Recipiente A ([tex]m =1200\,kg[/tex], [tex]V = 120\,m^{3}[/tex])
[tex]\rho = \frac{1200\,kg}{120\,m^{3}}[/tex]
[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]
El recipiente A tiene una densidad de 10 kilogramos por metro cúbico.
Recipiente B ([tex]m = 2400\,kg[/tex], [tex]V = 240\,m^{3}[/tex])
[tex]\rho = \frac{2400\,kg}{240\,m^{3}}[/tex]
[tex]\rho = 10\,\frac{kg}{m^{3}}[/tex]
El recipiente B tiene una densidad de 10 kilogramos por metro cúbico.
Ambos recipientes tienen la misma densidad, es decir, 10 kilogramos por metros cúbicos.
❗️URGENT NEED ASAP❗️
Given functions,
f(x) = -5x – 14 g(x) = -02 + 9x - 1
find f(9) + g(-2)
Answer:
Step-by-step explanation:
❗️URGENT NEED ASAP❗️
Given functions,
f(x) = -5x – 14 g(x) = -02 + 9x - 1
find f(9) + g(-2)
Answer:
Functions! Nice.
Step-by-step explanation:
This is a pretty simple concept.
What it wants you to do is to input those values inside the parentheses(9 or -2) into those equations for x. Then, you will have to add those values that you get.
If you didn't understand, watch and learn!
[tex]for x=9\\f(9)=-5(9)-14\\f(9)=-59\\[/tex]
Now try to do that for the second equation, but this time, have x as -2.
(I also can't solve the last one because I can't make sense of the equation. What is 02?)
Stay Safe!
P.S. When you find the answer to that second one, just add it to the first answer, and you'll get the final answer.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $25 monthly fee and charges an additional $0.10 for each minute of calls. The second plan has a $12 monthly fee and charges an additional $0.14 for each minute of calls For how many minutes of calls will the costs of the two plans equal
Answer:
The amount of minutes of calls in which the costs of the two plans equal is 325.
Step-by-step explanation:
To be able to find the amount of minutes of calls in which the cost of the two plans equal, you have to write an expression in which the price of the first and the second plan are the same an solve for the number of minutes:
25+0.10x=12+0.14x, where x is the number of minutes of calls.
Now, you can solve for x:
25-12=0.14x-0.10x
13=0.04x
x=13/0.04
x=325
According to this, the answer is that the amount of minutes of calls in which the costs of the two plans equal is 325.
Tavares is saving for a $350 cell phone.He already has $60 and plans to save an additional $20 per week?How many weeks will Tavares have to save before he can buy the cell phone ?

Selena wants to sell hot dogs at a local sports arena. She must pay a fee of $25 $25 to sell hot dogs and estimates each hot dog will cost her $0.75 $0.75 . Selena plans on selling each hot dog for $2.00 $2.00 . What is the minimum number of hot dogs ( x x ) Selena needs to sell for the revenue to be greater than or equal to her cost?
Answer:
20
Step-by-step explanation:
Let the cost of 1 hot dog be $x.
2x ≥ 25 + 0.75x
2x - 0.75x ≥ 25
1.25x ≥ 25
x ≥ 20
PLEASE HELP!!! Find the slope of each side of the triangle.
9514 1404 393
Answer:
AB: -3BC: 2/3AC: -1/4Step-by-step explanation:
The slope of a given segment is the ratio rise/run. The "rise" is the number of vertical divisions between the points. The "run" is the number of horizontal divisions between the points. The "run" is positive left-to-right. The corresponding "rise" is positive up.
Here are the segment slopes (rise/run).
AB = -3/1 = -3
BC = 2/3
AC = -1/4

Write an equation of the line that passes through a pair of points:
(-3,1). (-2,-5)
Answer:
[tex]y=-6x-17[/tex] (B)
Step-by-step explanation:
[tex]y=mx+b\\m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{1--5}{-3--2} = \frac{6}{-1} = -6\\y=-6x+b\\[/tex]
Plug in one of the two points for X and Y
(-3,1)
[tex]1=-6(-3)+b\\1=18+b\\b=-17\\\\y=-6x-17[/tex]

5. A line has a slope of (-3/2) and a
y-intercept of (-4). Write the equation of
the line.
Explanation:
Answer:
y = - [tex]\frac{3}{2}[/tex] x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - [tex]\frac{3}{2}[/tex] and c = - 4 , thus
y = - [tex]\frac{3}{2}[/tex] x - 4 ← equation of line
