Answer:
97.5/100
Step-by-step explanation:
To write 97.5% as a fraction in simplest form, we first convert the percentage to a decimal by dividing it by 100: 97.5% / 100 = 0.975. We can then express this decimal as a fraction by using the fact that any number can be represented as a fraction with the number as the numerator and a power of 10 as the denominator: 0.975 = 0.975/1. Finally, we simplify the fraction by dividing the numerator and denominator by the greatest common factor, which in this case is 1: 0.975/1 = 97.5/100. Therefore, 97.5% can be written as the fraction 97.5/100 in simplest form.
Answer:
39/40
Step-by-step explanation:
97.5/100
Step 1: Write down the percent divided by 100;
Step 2: If the percent is not a whole number, then multiply both top and bottom by 10 until you get an integer at the numerator.
Step 3: Simplify (or reduce) the fraction if it is not in the simplest form.

Answers
In linear equation ,The correct order from least time to greatest time is: Andy, Beth, Cindy.
Describe a linear equation using an example.
An equation with only one variable is referred to as a linear equation in one variable.
It has the mathematical formula Ax + B = 0, where A and B can be any two real numbers, and x is an unknowable variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.
Consider the provided information,
Andy walked [tex]2\frac{3}{4}[/tex] mi at a constant speed of [tex]2\frac{1}{2}[/tex] mi/h.
As we know
Time = distance/speed
= [tex]\frac{2\frac{3}{4} }{2\frac{1}{2} }[/tex]
= [tex]\frac{11/4}{5/2}[/tex]
= 11/40
Therefore, Andy takes 1.1 hours.
Beth walked 1 1/2 mi at a constant speed of 1 1/8 mi/h .
time = [tex]\frac{1 1/2}{ 1 1/8}[/tex]
= 3/2/ 9/8
= 4/3
Therefore, Beth takes 1.33 hours.
Cindy walked for 1 h and 24 min at a constant speed of 1[tex]\frac{1}{4}[/tex] mi/h.
1 hour 24 min = 1 + 24/60 = 1.4 hours
Therefore Cindy takes 1.4 hours.

Answers
The second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).
What is a quadratic equation?The equation of the form ax² + bx +c is known as a quadratic equation.
Given that, the zeros of the quadratic function are -7 and 1 and include the point (2,27/2).
Substitute x = 1 into the given inequality to check whether any of them becomes less than 0 or not:
From the first inequality:
y < -3/2 + 9 + 21/2
y < 18
From the second inequality:
y < 3/2 + 9 -21/2
y < 0
Since the inequality is less than 0, it is also less than the quadratic function at x = 1.
Similarly, checking the third inequality also gives y < 0, but the fourth doesn't.
Now, from the second and the third inequality, check which one is less than 27/2 for x = 2:
From the second inequality:
y < 6 + 18 -21/2
y < 27/2
From the third inequality:
y < -6-9+21/2
y < -27/2
Since the second inequality, y < (3/2)x² + 9x -21/2, is less than 0 at x =1 and less than 27/2 at x=2, it is also less than the quadratic function whose zeros are -7 and 1 and includes the point (2,27/2).
Hence, the second inequality, y < (3/2)x² + 9x -21/2, is less than the quadratic function with zero -7 and 1 and includes the point (2, 27/2).

One of the interior angles of the triangle, angle y is equal to 67° and the exterior angle x is equal to 113°.
Sum of interior angles of a triangle.The interior angles of a triangle have a total sum of 180°.
Considering the triangle with interior angles: y, 51°, and 62° we have that;
y + 51° + 62° = 180°
y + 113° = 180°
y + 113° - 113° = 180° - 113° {subtract 113° from both sides}
y = 67°
the exterior angle x and the angle y lie on a straight line, so they sum up to 180°.
x + 67° = 180°
x + 67° - 67° = 180° - 67° {subtract 67° from both sides}
x = 113°
Therefore, the interior angle y = 67° and the exterior angle x = 113°.

Find the domain and solve 2*4^(sqrt(5x^2-8x)+1)+4=33*2^(sqrt5x^2-8x)
Answers
To find the domain of the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we need to consider the values of x for which the expression is defined.
First, we need to consider the square root term, sqrt(5x^2-8x). The square root of a number is only defined for nonnegative values, so we need to find the values of x for which 5x^2-8x is nonnegative. We can do this by setting 5x^2-8x equal to 0 and solving for x:
5x^2-8x=0
5x(x-8)=0
We can see that x=0 and x=8 are the solutions to this equation. Since the square root of a negative number is not defined, the expression 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is only defined for x values that are greater than or equal to 0 and less than or equal to 8. This means that the domain of the expression is x ∈ [0, 8].
To solve the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)), we can start by isolating one of the exponential terms on one side of the equation. Let's isolate the term 2^(sqrt(5x^2-8x)):
24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x))
22^(2sqrt(5x^2-8x)+1)=332^(sqrt(5x^2-8x))
2^(2sqrt(5x^2-8x)+1)=16.52^(sqrt(5x^2-8x))
2sqrt(5x^2-8x)+1=4.5+sqrt(5x^2-8x)
sqrt(5x^2-8x)=3.5
5x^2-8x=12.25
5x^2-8x-12.25=0
We can use the quadratic formula to solve this equation for x:
x = (-(-8) ± sqrt((-8)^2 - 45(-12.25))) / (2*5)
x = (8 ± sqrt(64 + 97)) / 10
x = (8 ± sqrt(161)) / 10
x = (8 ± sqrt(289)) / 10
x = (8 ± 17) / 10
x = -9/10 or 25/10
Since x must be greater than or equal to 0 and less than or equal to 8, the only solution that is within the domain of the expression is x=25/10, or x=2.5.
Therefore, the solution to the equation 24^(sqrt(5x^2-8x)+1)+4=332^(sqrt(5x^2-8x)) is x=2.5.
what do you mean by domain of a function?
The domain of a function is the set of all input values for which the function is defined. In other words, it is the set of all values that can be plugged into the function as an argument, or input, and produce a valid output
For example, consider the function f(x) = x^2. The domain of this function is all real numbers, since the function is defined for any value of x. However, some functions may not be defined for certain values of x. For example, the function g(x) = 1/x is not defined for x=0 because division by zero is not allowed. In this case, the domain of the function g(x) would be all real numbers except for x=0.

d) The particle is moving right when 0 s < t < 1 s and t > 3 s and left when 1 s < t < 3 s.

f) The velocity increases at t = 1 s.
g) The particle has a total distance of 54 meters.
How to analyze the kinematics of a particle
In the statement we find the function of a particle that describes its position (y), measured in meters, in time (t), in seconds. Herein we shall analyze the function to determine all important features.
a) The velocity of the particle (v), in meters per second, is the first derivative of the function position:
v(t) = - 3 · t² + 12 · t - 9
b) The particle is at rest when v(t) = 0. Now we proceed to determine the roots of the resulting polynomial:
- 3 · t² + 12 · t - 9 = 0
t = 3 s. or t = 1 s.
c) The particle changes its direction when v(t) = 0. Then, this change happens in t = 1 s and t = 3 s.
d) The particle is moving right when v(t) > 0, then:
(t - 1) · (t - 3) > 0
There are two possible intervals: (i) 0 s < t < 1 s, (ii) t > 3 s. The particle is moving left when 1 s < t < 3 s.
e) The acceleration is the second derivative of function position, thus:
a(t) = - 6 · t + 12
f) The velocity increases when a(t) > 0. Then, the acceleration at t = 1 s is:
a(1) = - 6 · 1 + 12
a(1) = 6
The velocity is increasing at t = 1 s.
g) The total distance (s), in meters, traveled is determined by the following expression:
s = |x(1) - x(0)| + |x(3) - x(1)| + |x(6) - x(3)|
s = |7 - 11| + |11 - 7| + |- 43 - 11|

Let's first configure our system by giving x and y meaningful definitions. Let x be the total number of kids and y be the total number of adults.
Children cost $1.50, while adults cost $4.00. The number of kids, x, is multiplied by 1.5 to determine how much money a group of kids will cost. The 1.5x symbol stands for this. We will use 4y for adults, who must pay $4 to enter. On the specified day, $862 in total revenue was earned. We must add 1.5x and 4y to get at this sum.
1.5x + 4y = 862 equation required
Second equation: The total number of individuals present on the day is 283. X and Y, or the number of children and adults, must be added together to arrive at this figure.
x + y = 283
System of equations:
1.5x + 4y = 862
x + y = 283
Thus,
x + y = 283
y = 283 - x
Substitute y = 283 - x
862=1.5x + 4 (283 - x)
1.5x + 1132 - 4x = 862
1132 - 2.5x = 862
-2.5x = -270
x = 108
Substitute x =108 back into y = 283 - x
y = 283 - 108 = 175
Therefore there were 108 children and 175 adults in the amusement park on that particular day.

Answers
a) The percentage reduction in the price of the television each time is as follows:
First time = 10.42%Second time = 11.63%.b) The absolute change after the two reductions amounting to $100 is that the price of the television is now $380.
c) The overall percentage decrease in the price of the television is 20.83%.
What is the percentage?The percentage is the ratio.
The percentage is computed as the quotient of the smaller value (numerator) over the larger value (denominator), between two values.
Percentages are depicted using the percentage sign (%) to show that the value is expressed over 100.
Price of the television = $480
First price reduction = $50
New price after the first price reduction = $430 ($480 - $50)
Percentage reduction in price = 10.42% ($50/$480 x 100)
Second price reduction = $50
New price after the second price reduction = $380 ($430 - $50)
Percentage reduction in price = 11.63% ($50/$430 x 100)
Overall percentage decrease = 20.83% ($100/$480 x 100)
Thus, overall, the price of this television decreased by 20.83 percent.
