The total number that can be formed by the numbers 1,2,3,4,5 (without repeating digits) is 120.
Now, half of the unit's digit will be bigger than the ten's digit and in half of them it will be smaller.
Example: Let's say we have three digits 1,2,3. Total number of numbers without repeating digits = 3*2*1=6
Numbers with the Unit's digit greater than the ten's digit
123, 213, 312
Numbers with Ten's digits greater than the unit's digit
321, 132, 231
So total Number of cases = 120/2 = 60
Thus, the Total Number which can be formed by numbers 1,2,3,4,5 (without repeating digits) = 5*4*3*2*! = 5! = 120.

What is tangent class 10?
A tangent is a line that touches a curve at a single point, but does not intersect the curve at that point.
The slope of a tangent line at a point on a curve is equal to the derivative of the curve at that point. Therefore, finding the tangent line to a curve at a particular point is equivalent to finding the derivative of the curve at that point.
For example, consider the curve y = x^2. If we want to find the tangent line to this curve at the point (2,4), we can take the derivative of y = x^2, which is y' = 2x. Setting x equal to 2, we find that the slope of the tangent line at (2,4) is 4. We can then use this slope to find the equation of the tangent line: y - 4 = 4(x - 2), which simplifies to y = 4x - 4.

When you listen to the sound of a bouncing ping-pong ball that has been dropped onto a cement floor, what mathematical pattern do you hear? Explain,
A drop of water is denser than a ping-pong ball.
Usually, water is made of particles that are firmly pressed together. In differentiation, plastic (the material ping pong balls are made of) may be a lightweight fabric and the particles are not as firmly stuffed together.
The thickness of a ping pong ball is 0.0840 g/cm³, though water’s thickness is 997 kg/m³. Subsequently, ping pong balls aren’t about as thick as water and will continuously coast and surface greatly quickly.
The ping pong ball appears to oppose gravity and coast within the air.
Ping-pong balls drift within the water since they are amazingly lightweight, empty, and filled with air. Too, the water’s surface pressure makes it simple for the ping pong ball to drift.
In expansion, water is denser than ping pong balls, making them look for the most noteworthy point of water.

Alexis wants to take dance lessons over the summer. It costs a flat fee of $50.00 to
use the studio's facilities, then an additional $20.00 for each lesson. If Alexis has
$150.00, write an inequality that describes the number of lessons, x, Alexis can
take within her budget.
Answer:
5 Dance lessons
Step-by-step explanation:
The cost of taking x dance lessons is 50 + 20x dollars. This should be less than or equal to the amount of money Alexis has, which is 150 dollars. We can represent this relationship with the following inequality:
50 + 20x ≤ 150
This inequality can be simplified to the following:
20x ≤ 100
Dividing both sides of the inequality by 20 gives us the following:
x ≤ 5
Therefore, Alexis can take up to 5 dance lessons within her budget.

The amount of garbage thrown away each year by William's family, based on the details of the word problem, is 1.5 tons
What is a mathematical word problem?A word problem is a presentation of a mathematical question using complete sentences, rather than symbols and numbers, and for which the solution is obtained by using mathematical methods.
The amount (mass) of recyclable material a person produces each month = 50 pounds
The people in William's family are; His mother, father, two sisters
The number of people in Williams family = 5
The amount of recyclable material Williams family throw away each month = 50 × 5 pounds = 250 pounds
The number of months in a year = 12 months
The amount William's family throw away in a year = 12 × 250 pounds = 3000 pounds
1 pound = 0.0005 tons

The actual value of the bill can either be $90 or $81 or $18 or $54 or $27 or $72 or $36 or $63 bill.
A digit is a part of a set that, when taken as a whole, makes up a numeration system. A digit is a number in that particular circumstance. The members of the set 0 through 9 make up the digits of the decimal (base-10) Arabic numbering system.
The bill of customer was mistakenly interchanged by $45.
The sum of the two digits of the bill is 9.
Now,

If a shopkeeper undercharges a customer by interchanging the digits of the bill by $45 and the sum of the digits is 9, then the actual value of the bill is 72 dollars.
Therefore the answer is $72.
Let the tenth and once place value digits of the actual value of bill be x and y. Then actual value of bill in dollars is expressed by
10x + y
The value of bill obtained by interchanging the two digits in dollars is
10y + x
It is said that by interchanging digits the shopkeeper undercharged him by $45.0, that is
(10x + y) - (10y + x) = 45
9x - 9y = 45
Dividing by 9
[tex]\frac{9x + 9y}{9} = \frac{45}{9}[/tex]
x - y = 5
He remembers that the sum of the digits is 9, that is
x + y = 9
Solving the system of equations
x + y = 9
x - y = 5
Adding the equations
(x + y) + (x - y) = 9 + 5
2x = 14
Dividing by 2

a) 20
b) 24
c) 27
d) 30
e) 34
explain
We can rewrite m^91 + 2m^90 as (m+2m^90)^2 - m^90.
We are looking for values of m such that m+2m^90 is an integer.
For m = 30, m+2m^90 = 30 + 230^90 = 30 + 2(30^90) = 60, which is an integer.
For m = 24, m+2m^90 = 24 + 224^90 = 24 + 2(24^90) = 48, which is also an integer.
For the other values of m, m+2m^90 is not an integer. Therefore, the only values of m for which m^91 + 2m^90 is the square of an integer are m = 24 and m = 30.

Which is the slope of the line that passes through the points (- 3/5 and 1 3?
The slope(m) of the line that passes through the points (1, −3) and (3, −5) is m = -1.
The slope of a line determines the inclination of the line with the positive x-axis.
The slope of the line passing through (x1, y1) and (x2, y2) is given by m =(y2 - y1) / (x2 - x1)
Given that,
Here, (x1, y1) = (1, −3) and (x2, y2) = (3, −5)
m = (y2 - y1) / (x2 - x1)
m = [-5 - (-3)] / [3 - 1]
m = [-5 + 3] / [2]
m = [-2] / 2
m = -1
Slope = m = -1
Thus, The slope(m) of the line that passes through the points (1, −3) and (3, −5) is m = -1.

Which graph represents the function f of x equals 4 x?
The graph would be a straight line with a slope of 4, passing through the origin.
The equation f(x) = 4x can be expressed in slope-intercept form as y = 4x + 0, where the slope is 4 and the y-intercept is 0. This means that the graph of f(x) = 4x is a straight line with a slope of 4 that passes through the origin (0, 0).
The graph of f(x) = 4x is a line with a positive slope that passes through the origin and extends infinitely in both the positive and negative directions. The y-intercept is 0 and the x-intercept can be found by setting y = 0 and solving for x, which gives x = 0. For any given x-value, the corresponding y-value can be found by substituting the x-value into the equation f(x) = 4x and solving for y. As x increases, y increases proportionally, so the graph represents a linear, increasing relationship.

CAR is isosceles . so the angle of CER is 120° . ∠ACR = 60° and the inscribed angle of an arc is equal to half of the central angle of the arc ( the circumference angle theorem )
a) ∠ CAR = 1/2 ∠CER = 1/2 *120° = 60°
B) ∠ACR = 1/3 * 180° = 60°
C) ∠ARC = 1/3* 180° = 60°
D) measure of arc AC = measure of arc CR = 130°
E) measure of arc AR = measure of arc CR = 130 °
Measure of arc AC equals measure of arc CR = 130° when m arc CR = 130°. CAR = 1/2 CER = 1/2 *120° = 60°, ACR = 1/3 * 180° = 60°, ARC = 1/3* 180° = 60°.

Jade buys a blouse and a skirt for of their original price. She pays a total of $31.50 for the two items. If the original price of the blouse is $18, what is the original price of the skirt?
Part A
Which equation represents the situation?
O 0.75= 31.50
(18)= 31.50
O 0.75(s 31.50)=18
O
Part B
(18+5)= 31.50
Use the Distributive Property to solve the equation.
The equation that represents the situation could be 3/4(18 + s) = 31.50 and the solution is s = 24 thus option (D) is correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
Part (A)
Given that;
Cost of skirt = s
cost of blouse = $18
She bought it at 3/4 of that cost,
The Total pay = 3/4 of the total cost
3/4(18 + s) = 31.50
Part (B)
By the distributive property of multiplication then we get;
3/4(18) + 3/4(s) = 31.50
3/4(s) = 31.50 - 13.5
3/4(s) = 18
s = 18 x 4/3 = 24
Hence "The answer is s = 24"
