La extencion territorial de mexico es de 1960198 km2 , mientras que mocano tiene una superficie de 202.7 ha ¿cuantas veces cabe la superficie de mocano en la de mexico
Answer:
La superficie de mocano cabe 967.044 veces en la superficie de Mexico.
Step-by-step explanation:
Primero debemos convertir la unidad de la superficie (S) de mocano (m):
[tex] S_{m} = 202.7 ha*\frac{10000 m^{2}}{1 ha} = 2.027 \cdot 10^{6} m^{2} [/tex]
Ahora podemos calcular cuantas veces cabe la superficie de mocano en la de Mexico (M):
[tex] \frac{S_{M}}{S_{m}} = \frac{1.960198 \cdot 10^{9} m^{2}}{2.027 \cdot 10^{6} m^{2}} = 967.044 [/tex]
Si multiplicamos la superficie de mocano por 967.044 nos da la superficie de Mexico:
[tex] 967.044*2.027\cdot 10^{6} m^{2} = 1960198 m^{2} [/tex]
Por lo tanto, la superficie de mocano cabe 967.044 veces en la superficie de Mexico.

Which is the graph of y= -x-3?
Answer:
Graph a
Step-by-step explanation:
Answer:
the answer is A
Step-by-step explanation:
to start, I would use the slope intercept, in this case -3 which lets you know the slope meets the y axis at (0,-3) since you have that point, you count with the slope.
now slope is rise over run, therefore, it would be y over x and since the y in this case is 3, you'd go up three from your point. since x is 4, you'd go right four units from where you are. since A is the only graph that follows that, A would be correct.
How can you use the DISTRIBUTIVE PROPERTY solve the equation: 3(x-4) = 24 ? *
By using the Distributive Property, you would multiply 3 into the parenthesis (3 · x and 3 · -4)
3(x - 4) = 24
3x - 12 = 24
Then, you would solve like any normal one-step equation.
3x - 12 = 24
+12 +12
__________
3x 36
__ = __
3 3
x = 12, which is your final solution.
If you need any further explanations, please ask me :)
Answer:
3(x - 4) = 24 This is the normal equation.
3x - 12 = 24 Next, use the distributive property and multiply everything in the parentheses by the number on the right of the parentheses, which in this case is 3. 3 times x is 3x, and remember to use any symbols to the left of the numbers and use as if it was a negative. 3 times -4 -12. Get rid of the parentheses and replace with the new numbers, which are 3x and -12.
3x = 36 I think you are solving for X so that's what i'm doing.
x = 12
density of the cube is 9.86 g/cm³ and the volume is 150cm³ work out the mass in kg
Mass= Density *Volume
9.86 g/cm3 *150 cm3 =1479g
1479 g to kilograms
1479g= x
1000g = 1 kg
x = 1479 g / 1000 x = 1.479 kg.

red bike is traveling south, toward Lawrence, at constant speed of 24km/h and a blue bike is also traveling east, away from Lawrence, at a constant speed of 12 km/h. when t=0, the red bike is 10 km north and the blue bike is 6 km east of Lawrence a. express the distance of the red bike from Lawrence, R, as a function of time in hours, t. b. express the distance of the blue bike from Lawrence, B, as a function of time in hours, t.
Answer:
a.[tex]R=10-24t[/tex]
b.[tex]B=6+6t[/tex]
Step-by-step explanation:
We are given that
Speed of red bike, v=24 km/h
Speed of blue bike, v'=12km/h
Distance of red bike when t=0
=10 km north
Distance of blue bike when t=0
=6km east
a. We have to find the expression of distance of red bike from Lawrence.
[tex]Distance=speed\times time[/tex]
Let t be the time taken by red bike
Distance of red bike from Lawrence is given by
[tex]R=10-24\times t[/tex]
[tex]R=10-24t[/tex]
b.
Distance of the blue bike from Lawrence
[tex]B=6+6\times t[/tex]

The functions f(x) and g(x) are shown on the graph.
f(x) = x²
What is g(x)?
The required function g(x) is given as g(x) = 3x².
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
In the graph, we have a graph of two functions,
f(x) = x² and there is a point (2, 12) located on the curve of function g(x)
we have to determine the function g(x).
Now,
Now, as g(x) is scaled function of f(x)
g(x) = k f(x) - - - - (1)
At x = 2
g(2) = 12
f(2) = 4
Put x = 2 in question 1,
g(2) = k(f(2))
12=k*4
k = 3
Substitute k in equation 1 we get,
g(x) = 3x²
Thus, the required function g(x) is given as g(x) = 3x².
