Answer:
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.
Step-by-step explanation:
Asumamos en primer lugar que los tres amigos rentan la cuatrimoto durante una hora, entonces cada persona utiliza la cuatrimoto en proporción al dinero. A continuación, obtenemos el tiempo estimado por cada usuario a partir de una regla de tres simple:
[tex]\Delta t = \frac{c_{a}}{c_{r}}\cdot (60\,min)[/tex]
Donde:
[tex]\Delta t[/tex] - Tiempo de uso de la cuatrimoto, medido en minutos.
[tex]c_{a}[/tex] - Dinero aportado por el usuario, medido en pesos.
[tex]c_{r}[/tex] - Coste de renta de la cuatrimoto, medido en pesos.
Entonces calculamos el tiempo correspondiente a cada amigo:
Adriana ([tex]c_{a} = \$\,50[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,50}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 7.5\,min[/tex]
Luis ([tex]c_{a} = \$\,160[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,160}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 24\,min[/tex]
Ramiro ([tex]c_{a} = \$\,190[/tex], [tex]c_{r} = \$\,400[/tex])
[tex]\Delta t = \frac{\$\,190}{\$\,400}\times 60\,min[/tex]
[tex]\Delta t = 28.5\,min[/tex]
Adriana debe subirse durante 7.5 minutos, Luis durante 24 minutos y Ramiro 28.5 minutos.

Answer:
The length of C'D' = 2.8
This is because, ABCD is rotated on the point R 55 degrees
So, now, if you turn back the rotation, you will get, that CD = C'D'
Now, CD = 2.8 , So, C'D' = 2.8

Angel H and G are both are 51 degrees, and angle I is 78 degrees.
The two angles (H and G) are equal to each other, but before we know what the angles are, we must find x.
[tex]5x + 6 = 2x + 33[/tex]
[tex]3x = 27[/tex]
[tex]x = 9[/tex]
Plug in x for one equation:
[tex]5x + 6[/tex]
[tex]5(9) + 6[/tex]
[tex] = 51[/tex]
Therefore,
[tex]m < h = 51 \:[/tex]
and
[tex]m < g = 51[/tex]
And because we know the angles within a triangle = 180, we subtract 102 from 180 to find m<I:
[tex]180 - (51 + 51) = [/tex]
[tex]180 - 102 = [/tex]
[tex] = 78[/tex]

ASAP PLS HELP
Answer with step-by-step explanation:
(4 x 2x) - (4 x 3) = 8x - 12
Hope this was helpful!
Answer: 8x + -12
Explanation: Let's simplify this problem using the distributive property.
The first thing we want to do is change the minus to plus a negative.
Now we can distribute or multiply this 4 times
each of the terms inside the set of parenthses.
So we get 4(2x) + 4(-3) and this simplifies to 8x + -12.
Note that if you wrote your answer as 8x - 12, it means the same thing.

25. Willa purchases a vase for her kitchen
that is shaped like a cube and will hold 343
cubic inches of water. What are the
dimensions (length, width and height) of the
vase?
Answer:
7,7, and 7
Step-by-step explanation:
If she vase is cubical we know that all 3 dimensions are the same. This means that x^3 = 343. So we know the answer is the cube root of 343, which is 7
The dimensions of the cubic vase are 7 by 7 by 7.
What is a cube?A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.
Given that the volume of the cubic vessel is 343 cubic inches.
The formula for the volume of a cube of side length a is:
V =a³
Substitute V= 343:
343 = a³
Or, a = ∛343
a = 7
Hence, the dimensions of the cubic vase are 7 by 7 by 7.

find the nth terms of the sequence with the following first four terms as shown in the table.
________________________
n 1 2 3 4
________________________
an 5 9 13 17
_______________________
Answer:
see explanation
Step-by-step explanation:
Both sequences have a common difference between consecutive terms, that is
2 - 1 = 3 - 2 = 4 - 3 = 1
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 1 and d = 1 , thus
[tex]a_{n}[/tex] = 1 + n - 1 = n
--------------------------------------------------------------------
Similarly
d = 9 - 5 = 13 - 9 = 17 - 13 = 4 and a₁ = 5 , then
[tex]a_{n}[/tex] = 5 + 4(n - 1) = 5 + 4n - 4 = 4n + 1
2x - (3-x) > x+1 solve
Answer:
x > 2
Step-by-step explanation:
Step 1: Write inequality
2x - (3 - x) > x + 1
Step 2: Solve for x
Distribute negative: 2x - 3 + x > x + 1Combine like terms: 3x - 3 > x + 1Subtract x on both sides: 2x - 3 > 1Add 3 to both sides: 2x > 4Divide both sides by 2: x > 2Here we see that any value x greater than 2 would work as a solution.

Step-by-step explanation:
I used google to search up exponential function and it showed a lot of graphs and they're all curved.
For an exponential function, Its graph is a smooth curve. Option 3 is correct.
What is an exponential function?It is defined as a function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = aˣ, where a is a constant and a>1.
A smooth curve can be found on the graph of an exponential function, which uses exponents. In an exponential function, the rate of change is not constant. Exponential functions include the ones at y = 0.5x and y = 2x in the graph below.
Because the slopes of exponential functions are nonlinear and constantly changing, their graphs resemble curves rather than straight lines.
Hence, for an exponential function, Its graph is a smooth curve. Option 3 is correct.
