The percentage K 25 that is 25 t, can be found to be 1 % .
How to find the percentage ?The relationship between K and t is such that 1 K has 100 t.
This means that K 25 in terms of t, would be:
= 25 x 100
= 2, 500 t
The percentage of K that is 25 t is therefore :
= 25 / 2, 500
= 1 / 100
= 0. 01
= 1 %
In conclusion, when given the values K 25 and 25 t, then 25 t would be 1 % of K 25.

Translate the following sentence into an equation: "The product of 3 and x increased by 7 equals 25 ."
Consider the function f(x) = (x - 3)^2
a. How could you restrict the domain of f(x) so that its inverse will be a function?
b. Graph f(x) with its restricted domain and then graph its inverse on the same set of axes.
c. Find the equation of the inverse of f(x) with its restricted domain.
Answer:
Step-by-step explanation:
a) As the function is a quadratic you could restrict the domain by taking only values either side of the line x = 3. This means the domain will be
a) 3<x<∞
Or
b) -∞<x<3
b) the graph is attached below.
c) The equation of the inverse of f(x) can be found by switching x and y:
X = (y-3)²
√x = y - 3
y = √x + 3
However this takes in positive and negative values of the square root function. So in order to restrict this, we can take the positive square root only.
Thus y = +√x + 3
the diagram below shows the graph of y=x^2+2x-3 for the domain -4 2. use the graph to determine the scale used on the x- axis, the value of y for which x= 1.5, the values of x for which y=0 and the range of values of y, giving your answer in the form a

Classify each ordered pair as a solution or not a solution of the inequality y
a inequality y <2/7 x − 5.
The ordered pairs (21, 0) and (6, -4) are the solutions to the given inequality.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given inequality is y<2/7x-5.
Here,
Put (x, y)=(21, 0) in the given inequality, we get
0<2/7(21)-5
0<1
So, it is solution
Put (x, y)=(6, -4) in the given inequality, we get
-4<2/7(6)-5
-4<12/7-5
-4<1.7-5
-4<-3.3
So, it is solution
Put (x, y)=(0, -5) in the given inequality, we get
-5<2/7(0)-5
-5<-5
Which is not true, it is not a solution
Put (x, y)=(7, -3) in the given inequality, we get
-3<2/7(7)-5
-3<-3
Which is not true, it is not a solution
Therefore, the ordered pairs (21, 0) and (6, -4) are the solutions to the given inequality.

The Son has got his Crown On The pharaoh’s outfitters, ‘Cloaks and Crowns’, sell Cloaks and Crowns in 3 sizes – prince, king and emperor (in increasing size order). He wants to kit out his three sons for the forthcoming festival of Ra. Ahmose chooses a bigger cloak than Kamose, but a smaller crown than Thutmose. Both Thutmose’s cloak and crown are larger than Kamose’s, but the size of Thutmose’s crown matches the size of Kamose’s cloak. Which sizes did the pharaoh’s sons each get?
The only possible solution for system is A = 2, B = 1, and C = 3, which means Thutmose got the emperor size crown and cloak, Kamose got the prince size cloak and king size crown, and Ahmose got the king size cloak and prince size crown.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Let's us consider the sizes of the cloaks by C (prince), B (king), and A (emperor)
The sizes of the crowns by 1 (prince), 2 (king), and 3 (emperor).
Now let us write the following system of inequalities:
B > C
A > B
3 = C (Thutmose's crown matches Kamose's cloak)
2 > C
A > 3
A > 2 (Thutmose's crown is larger than the king size crown)
From the fifth inequality, we know that Thutmose's cloak is the largest of all three cloaks, so A must equal C.
Therefore, we can simplify the system of inequalities to:
B > C, A > B, C = 3, 2 > C, A > 3 and A > 2
Hence, the only possible solution for system is A = 2, B = 1, and C = 3, which means Thutmose got the emperor size crown and cloak, Kamose got the prince size cloak and king size crown, and Ahmose got the king size cloak and prince size crown.

Calculate the volume of this cylinder, giving your answer to 1 decimal point
The volume of the cylinder is approximately 1413.7 cubic centimeters.
The formula for the volume of a cylinder is V = πr²h, where r is the radius of the base and h is the height or length of the cylinder.
Since the base of the cylinder has a diameter of 9cm, the radius is half of that, or r = 4.5cm.
The length of the cylinder is given as 20cm.
Therefore, the volume of the cylinder is:
V = πr²h
= π(4.5)²(20)

Find the gradient of the line that passes through (3, 7) and (1, 10).
Answer:
-1.5
Step-by-step explanation:
The gradient of a line can be found using the formula:
gradient = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
So for the line that passes through (3, 7) and (1, 10), the gradient can be found as:
gradient = (10 - 7) / (1 - 3)
gradient = 3 / -2
gradient = -1.5
So the gradient of the line that passes through (3, 7) and (1, 10) is -1.5.
A circle has a diameter of 26 feet what is the circumference
Use 3.14 for pie and do not round your answer be sure to include the correct unit in it in your answer
The circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.
What is the circumference?
The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated as a pole.
The formula for the circumference of a circle is 2 * π * r, where r is the radius of the circle.
To find the circumference, we first need to find the radius of the circle.
The diameter of the circle is 26 feet, so the radius can be calculated by dividing the diameter by 2:
r = 26 feet / 2 = 13 feet
Now that we know the radius, we can find the circumference:
C = 2 * π * r = 2 * 3.14 * 13 = 81.64 feet
Therefore, the circumference of a circle with a diameter of 26 feet is approximately 81.64 feet.

a statistics professor finds that when he schedules an office hour for student help, an average of students arrive. find the probability that in a randomly selected office hour, the number of student arrivals is
The probability of 3 students arriving at a randomly selected office hour is 0.27(27%). This can be calculated by using the Poisson distribution equation which is P(x)=e^(-λ)*(λ^x/x!).
In the above equation, λ is equal to the average number of arrivals which is 3.3. Plugging these values into the equation gives us P(3)= e^(-3.3)*(3.3^3/3!) = 0.27, this means that the probability of 3 students arriving in randomly selected office hours is 0.27.The Poisson distribution is used to calculate the probability of a certain number of events occurring in a fixed interval of time or space. It is commonly used in engineering, economics, and other fields.

The probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is 2/3, in simplest form.
The table shows the information about the gym membership and lunch habits of 100 physical therapists.
Given that a physical therapist brings their lunch to work, we can use the information in the table to calculate the probability that they do not use the gym membership. To do this, we'll use the formula:
P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch)
We can use the information in the table to find the values of P(not using gym membership and brings lunch) and P(brings lunch).
P(not using gym membership and brings lunch) = 40/100 = 2/5
P(brings lunch) = 60/100 = 3/5
So, the probability that a randomly chosen physical therapist does not use the gym membership given that they bring their lunch to work is:
P(not using gym membership | brings lunch) = P(not using gym membership and brings lunch) / P(brings lunch) = (2/5) / (3/5) = 2/3
