Richard and Teo have a combined age of 28. Richard is 13 years older than twice Teo’s age. How old are Richard and Thiago?
Richard is 23years old and Thiago is 5years old
What is word problem?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation.
From the question,
Let R stands for Richard
T stands for Teo
we were told that the combined age of Richard and Teo is 28
i.e
R + T = 28 ......eqn (i)
we were also told that Richard is 13 years older than twice Teo’s age
i.e
R = 2T + 13 .....eqn(ii)
substituting 2T + 13 for R in eqn (i)
(2T+13)+T = 28
expanding the bracket
3T + 13 = 28
collecting like terms
3T = 28 - 13
3T = 15
T = 15/3
T = 5
Teo age is 5years
From eqn (i)
R + T = 28
R + 5 = 28
R = 28 - 5
R = 23
Hence, Richard age is 23years
From eqn (ii)
R = 2T + 13
substituting for R in the eqn
23=2T+13
collecting like terms
23-13=2T
10=2T
T=10/2
T=5
Hence. Thiago age is 5years

m1 = (0 - 5)/(0 - (-3))
m1 = -5/3
A line 'b' passes through points (3,5) and (0,0).
Let m2 be the slope of line 'b'
m2 = (0 - 5)/(0 - 3)
m2 = (-5)/(-3)
m2 = 5/3

For a project in his Geometry class, Feng uses a mirror on the ground to measure the height of his school’s flagpole. He walks a distance of 8.65 meters from the flagpole, then places a mirror on flat on the ground, marked with an X at the center. He then steps 1.1 meters to the other side of the mirror, until he can see the top of the flagpole clearly marked in the X. His partner measures the distance from his eyes to the ground to be 1.65 meters. How tall is the flagpole? Round your answer to the nearest hundredth of a meter.
The height of the flagpole, found using the ratio of the sides of similar triangles is 12.975 meters
What are similar triangles?Similar triangles are triangles in which two angles of one triangle are congruent to two angles in the other triangle, such that they have the same shape.
The parameters that can be used to find the height of the flagpole are;
Distance of the mirror from the flagpole = 8.65 meters
Distance of Feng on the other side of the flagpole = 1.1 meters
The height from Feng's eyes to the ground = 1.65 meters
According to the law of reflection, the angle of incident and the angle of reflection are the same
The angle made by Feng and the ground = Angle made by the flagpole and the ground = 90°
The triangle formed by the Feng and the flagpole are therefore similar by AA similarity postulate
The ratio of corresponding sides of similar triangles are the same, therefore;
[tex]\dfrac{1.65}{Height\, of \, the \, flagpole} = \dfrac{1.1}{8.65}[/tex]
[tex]Height\, of \, the \, flagpole = \dfrac{1.65}{1.1} \times 8.65 = 12.975[/tex]

9x² + 31x+ 20 = ( ? ) ( ? )
2x² +7x-4 = ( ? )( ? )
2x² - 13x-5 = ( ? )( ? )
Answer: The square root of 169 is 13, so the two solutions for x are:
x = (13 + 13) / 4 = 3.25
x = (13 - 13) / 4 = -0.25
Since the quadratic expression 2x^2 - 13x - 5 equals 0 when x is either 3.25 or -0.25, the factors of this expression are (x - 3.25)(x + 0.25).
In summary, the factors of the first quadratic expression are (x + 1.056)(x + 5.937), the factors of the second expression are (x - 0.75)(x + 3.75), and the factors of the third expression are (x - 3.25)(x + 0.25).
Step-by-step explanation: To find the factors of a quadratic expression, we can use the quadratic formula. The quadratic formula states that for a quadratic expression of the form ax^2 + bx + c = 0, the solutions for x are given by the formula x = (-b ± sqrt(b^2 - 4ac)) / (2a).
In the first equation, a is 9, b is 31, and c is 20. Plugging these values into the quadratic formula, we get:
x = (-31 ± sqrt(31^2 - 4 * 9 * 20)) / (2 * 9)
This simplifies to:
x = (-31 ± sqrt(961 - 720)) / 18
This further simplifies to:
x = (-31 ± sqrt(241)) / 18
We can find the value of the square root by using a calculator or by remembering some common square roots. The square root of 241 is approximately 15.937, so the two solutions for x are:
x = (-31 + 15.937) / 18 = -1.056
x = (-31 - 15.937) / 18 = -5.937
Since the quadratic expression 9x^2 + 31x + 20 equals 0 when x is either -1.056 or -5.937, the factors of this expression are (x + 1.056)(x + 5.937).
We can use the same approach to find the factors of the other two quadratic expressions. For the second expression 2x^2 + 7x - 4, the values of a, b, and c are 2, 7, and -4, respectively. Plugging these values into the quadratic formula, we get:
x = (-7 ± sqrt(7^2 - 4 * 2 * -4)) / (2 * 2)
This simplifies to:
x = (-7 ± sqrt(49 + 32)) / 4
This further simplifies to:
x = (-7 ± sqrt(81)) / 4
The square root of 81 is 9, so the two solutions for x are:
x = (-7 + 9) / 4 = 0.75
x = (-7 - 9) / 4 = -3.75
Since the quadratic expression 2x^2 + 7x - 4 equals 0 when x is either 0.75 or -3.75, the factors of this expression are (x - 0.75)(x + 3.75).
For the third expression 2x^2 - 13x - 5, the values of a, b, and c are 2, -13, and -5, respectively. Plugging these values into the quadratic formula, we get:
x = (13 ± sqrt(13^2 - 4 * 2 * -5)) / (2 * 2)
This simplifies to:
x = (13 ± sqrt(169 + 40)) / 4

Probability of rolling an odd number on a single die is 3/6, or 1/2. This is because there are three odd numbers (1, 3, and 5) on a standard six-sided die, and the probability of rolling any given number is 1/6.
What is meant by Probability?Probability is a metric used to determine how likely an event or result is to occur. A decimal or fraction between 0 and 1 is typically used to express it, with 0 denoting that the event will not occur and 1 denoting that it will occur without a doubt. For instance, the likelihood of rolling a 6 on a conventional six-sided die is 1/6 since there is only one scenario out of the six conceivable events that will result in rolling a 6. By dividing the number of desired outcomes by the total number of potential possibilities, one may compute probability. In general, the more likely an event is to occur, the greater its probability.
