Answer:
The value of n is 1/2.
Step-by-step explanation:
[tex] {25}^{2n + 1} = 625[/tex]
[tex] log_{25}(625) = 2n + 1[/tex]
[tex]2 = 2n + 1[/tex]
[tex]2n = 1[/tex]
[tex]n = \frac{1}{2} [/tex]
The solution for the given equation is n=624/625.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation is 25²n+1=625.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 625n+1=625
625n=624
n=624/625
Therefore, the solution for the given equation is n=624/625.

Answer:

Let the speed of the train be x km/hr and the speed of the bus is y km/hr.
So according to question and using
[tex] \huge \boxed{\sf{Time = \frac{Distance}{speed}}}
[/tex]
Total distance =300 km
Mansi travels 60 km by train and 300−60=240 by bus in 4 minute,
[tex] \bf\frac{60}{x} + \frac{240}{y} = \red4
[/tex]
and 100 km by train, 300−100=200 by bus, and takes 10 minutes more,
[tex] \bf {\frac{100}{x} + \frac{200}{y} = 4 + \frac{1}{6} = \frac{24 + 1 }{6} = \purple{\frac{25}{6}}}
[/tex]
Now, let
[tex]\bf\color{blue}{\frac{1}{x} = a}[/tex]
and.
[tex] \bf \color{blue}{ \frac{1}{y} = b }[/tex]
[tex]\bfthen 60a+240b=4.............(1)[/tex]
[tex]\bf100a+200b=25/6----(2)[/tex]
multiply (1) by 5 and (2) by 6 we get
[tex]\bf300a+1200b=20..........(3)[/tex]
[tex]\bf600a+1200b=25...........(4)[/tex]
Subtracting (3) and (4) we get
[tex]\bf \green{−300a=−5}[/tex]
[tex]\bf{a = \frac{1}{60}}[/tex]
Putting the value of a in (1) we get
[tex]\bf{60 \times \frac{1}{60} + 240b = 4}[/tex]
[tex]
\bf240b = 3 \\ \\ \bf b = \frac{1}{80} [/tex]
Now ,
[tex] \bf\frac{1}{x} = a \\ \\ \bf \red{a = 60 km/h \: \blue \bigstar}[/tex]
[tex] \bf\frac{1}{y} = b \\ \\ \bf \red {b = 80 km/h \: \pink \bigstar} [/tex]
Hence, the speed of the train is 60 km/hr and the speed of the bus is 80 km/hr.

Transversal c intersects lines a and b. Prove that a||b in each case.
FILL IN THE STATEMENT REASON CHART!!! WILL ONLY ACEPPT THOSE ANSWERS!!!
'a' is parallel to 'b' because both agree with the same - side exterior theorem
What is the same - side theorem?It states that when two parallel lines are cut by a third intersecting line (transversal line), eight angles are formed and these angles form different relationships with each other, called same-side exterior.
Same-side tells us that exterior tells us that both angles are exterior, or outside, of the parallel lines.
In the figure, angles a, b, c, and d are exterior to the parallel lines.
We can then say that;
a is parallel to b because both agree with the same - side exterior theorem
Hence, 'a' is parallel to 'b' because both agree with the same - side exterior theorem

Identify an equation that models the situation and find its solution. Kane planned to build a 53-centimeter-tall model of a building. He later decided to increase the model's height to 159 centimeters. What was the increase of the model's height in centimeters?
Answer:
The increment in the model is 106cm
Step-by-step explanation:
Given
[tex]Initial\ Height = 53cm[/tex]
[tex]Final\ Height = 159cm[/tex]
Required
Determine the increment
To do this, we simply subtract the initial height of the building from the final height
[tex]Increment = Final\ Height - Initial\ Height[/tex]
[tex]Increment = 159cm - 53cm[/tex]
[tex]Increment = 106cm[/tex]
Hence, the increment in the model is 106cm

Two lines intersect parallel lines m and n as shown. What is the value of x? A)24 B) 48 C)60 D) 66
Answer:
C. 60
Step-by-step explanation:
48+72=120
x=180-120
x=60
The value of x from the given diagram is 60 degrees
The sum of the interior angle of a triangle is 180 degrees. Since the two lines intersect parallel lines m and n, then;
m<3 = 48 degrees (alternate interior angle)Taking the sum of angle in the triangle;
m<3 + x + 72 = 180
48 + x + 72 = 180
120 + x = 180
x = 180 - 120
x = 60 degrees
Hence the value of x from the given diagram is 60 degrees

Sarah creates bouquets of flowers with an equal number of flowers in each bouquet. She had 240 flowers when she started, with 128 flowers remaining after she created 7 bouquets. This situation can be represented by the linear equation y=24 - 1x where y is the total number of flowers, and x is the number of bouquets created. How many flowers are in each bouquet? (The variables can only be positive numbers.)
Answer:
16 flowers per bouquet
Step-by-step explanation:
if you try to solve this question using the given equations the answer will not make a lot of sense:
y = 24 - 1x
128 = 24 - 7x
-7x = 128 - 24 = 104
x = 104 / -7 = -14.86 flowers
the equation is not correct, it should be:
y = 240 - 1x
128 = 240 - 7x
7x = 240 - 128 = 112
x = 112 / 7 = 16 flowers per bouquet

What is the domain ?
What is the range?
I will brainiest someone please I need the help!!
Answer:
The y-intercept is (0, 8)
The x-intercepts are (2, 0) and (4, 0)
The axis of symmetry is a vertical line at x = 3
The vertex is (3, -1)
The graph has a minimum value -1 at x = 3
The domain is {x: x ∈ R} ⇒ (-∞, ∞)
The range is {y: y ≥ -1} ⇒ [-1, ∞)
Step-by-step explanation:
By using the given figure
The figure represents a parabola (the graph of a quadratic function
∵ The parabola intersects the y-axis at point (0, 8)
∴ The y-intercept is (0, 8)
∵ The parabola intersects the x-axis at point (2, 0) and (4, 0)
∴ The x-intercepts are (2, 0) and (4, 0)
∵ The axis of symmetry of the parabola is a vertical line that passes
through the vertex of it
∵ The x-coordinate of the vertex point is 3
∴ The axis of symmetry is a vertical line at x = 3
∵ The vertex of the parabola is the lowest point on the graph
∵ The lowest point is (3, -1)
∴ The vertex is (3, -1)
∵ The vertex point of the graph is the lowest
∴ The graph has a minimum value -1 at x = 3
∵ The domain is all values of x belong to the parabola
∵ x could be any real number
∴ The domain is {x: x ∈ R} ⇒ (-∞, ∞)
∵ The range is all the values of y from the lowest point
∵ The y-coordinate of the lowest point is -1
∴ The range is {y: y ≥ -1} ⇒ [-1, ∞)
solve for x.

Answer:
[tex]Probability = 0.04[/tex]

Given
[tex]Striped = 2[/tex]
[tex]Colored = 5[/tex]
[tex]White = 3[/tex]
Required
Determine the probability that both selections are stripped
This is calculated as:
[tex]Probability = P(Stripped) * P(Stripped)[/tex]

Can someone tell me the answer too this, Denver,Colorado often experiences snowstorms resulting in multiple inches of accumulating snow during the last snowstorm the snow accumulated at 4 5 in./h if there's no continues at this rate for 10 hours how much snow will accumulate
Answer:
8 inches
Step-by-step explanation:
Given that:
Rate of Snow accumulation = [tex]\frac{4}{5}\ in/hr[/tex]
Time for which the snow gets accumulated at the same rate = 10 hours
To find:
How much snow will get accumulated if the snow keeps accumulating at the same rate ?
Solution:
To get the amount of snow that got accumulated, we need to multiply the rate of snow accumulation with the time for which the snow kept on accumulating.
Formula:
Amount of snow accumulated = Rate of snow accumulation [tex]\times[/tex] Time taken for snow accumulation
[tex]\Rightarrow \dfrac{4}{5}\times 10\\\Rightarrow 4\times 2\\\Rightarrow \bold{8\ inches}[/tex]
Therefore, 8 inches of snow got accumulated.
