A triangle has sides with lengths of 39 mm 56 mm and 37 mm is it a right triangle
No it is not a right angled triangle.
What is a right angled triangle?A right triangle is a triangle with a 90° angle as its only angle. There CANNOT be two 90° angles in a right triangle. This is so that a triangle's angles can sum up to 180°. The right triangle's other two angles must sum up to 90 degrees given that one angle is 90 degrees.A triangle is a right triangle if the square of the length of the longest side equals the sum of the squares of the other two sides. In other words, if c2=a2+b2 in ABC, then C is a right triangle with PQR as the right angle.acc to our question-
a= 39b=56c=37Hence, no sides are equal to 90 degrees.

a) The variable x is the average distance of Venus from the sun.
b) The equation for the given condition,
⇒ ⇒ 57.9 = 3.8 + x/2
c) The average distance of Venus from the sun = 108.2 million kilometers.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The average distance of Mercury from the sun = 57.9 million kilometers
And, This distance is 3.8 million kilometers more than half the average distance of Venus from the sun.
Now,
Since, The average distance of Mercury from the sun = 57.9 million kilometers
And, This distance is 3.8 million kilometers more than half the average distance of Venus from the sun.
Let the average distance of Venus from the sun = x
So, We can formulate;
⇒ 57.9 = 3.8 + x/2
Solve for x as;
⇒ 57.9 = 3.8 + x/2
⇒ 57.9 - 3.8 = x/2
⇒ x/2 = 54.1
⇒ x = 54.1 × 2
⇒ x = 108.2
Thus, The average distance of Venus from the sun = 108.2 million kilometers.
Therefore, a) The variable x is the average distance of Venus from the sun.
b) The equation for the given condition,
⇒ ⇒ 57.9 = 3.8 + x/2
c) The average distance of Venus from the sun = 108.2 million kilometers.

Equation:
An equation is made up of two expressions connected by an equal sign. For example, 2x – 5 = 16 is an equation.
Given,
A biologist is studying the elk population in a county park. She starts with only 2 elk and observes that the number of elk triples every year.
Here we need to find the equation that will shows the number of years, y, it will take for the population to reach 1,458 elk.
Let us consider n be the number of years take for the population to reach 1,458 elk.
So, according to the given question, we have written as,
f(n) = 2 x 3ⁿ
Here we know that the value of f(n) = 1458, then the equation is written as,

We have the following information:
An article in the New York times noted that the human population has shown a significant increase in height. when the relationship of height to reproductive success in humans was examined across three decades (1935-1967), height had a positive correlation to the number of children born and the number of surviving children.
It means if the number of children born and the number of surviving children is more then the population will also increase.
In other words, it can be said population is directly proportional.

Points C and D are 13.82 meters apart.
What is the point in math?
In mathematics, a point (.) is used to indicate an accurate place in space and serves as its representation. It lacks all three dimensions—length, width, and height. It is hence immeasurable. Uppercase letters are typically used to name points.Given : Flag AB, with point B , C ,D lying on ground.
BD = 24 m . AB = 42 m
To find; CD
In triangle ABD, with angle of elevation from D to top of flag pole is 48 degrees.
Tanθ = perpendicular/base

Following equation represents a circle with its Centre at the origin is ,

What is circle?
A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point.
What does origin mean math?
The origin is the point at which all lines in a coordinate system intersect. When x and y are both equal to zero, the axes intersect. The origin's coordinates are (0, 0).
What is equation?
An equation is a mathematical statement that demonstrates the equality of two mathematical expressions.
What is Pythagoras theorem?
The Pythagorean Theorem states that the squares on the hypotenuse (the side across from the right angle) of a right triangle, or, in standard algebraic notation, [tex]a^2 + b^2=c^2[/tex], are equal to the squares on the legs.
If we take any point P(x, y) on the circle, then OP = 5 is the radius of the circle.
But OP is also the hypotenuse of the right-angled triangle OPN, formed when we drop a perpendicular from P to the x-axis.
Now in the right-angled triangle, ON = x and NP = y. Thus, using the theorem of Pythagoras,

What are all the rational roots of the polynomial f/x 20x4 x3 8x2 x 12?.
The rational roots of the given polynomial f(x)= 20x4 + x3 + 8x2 + x - 12 are x = -4/5 and x = 3/4.
All possible rational roots of f(x) are in the form p/q where p is a factor of constant term and q is the coefficient of leading term. Here, p= -12 and q= 20
Factors of -12= -/+(1,2,3,4,6,12)
Factors of 20= -/+(1,2,4,5,10,20)
So the rational roots = -/+ (1, 2, 3, 4, 6, 12)/ (1, 2, 4, 5, 10, 20)
Solving for x when f(x) = 0,
20x4 + x3 + 8x2 + x - 12 = 0
(4x - 3)(5x + 4)(x2 + 1) = 0
Equating all factors to zero, we get
4x - 3 = 0 or 5x + 4 = 0 or x2 + 1 = 0
x = 3/4, x = -4/5, x = i, x = -i
Hence, the rational roots are x = 3/4, x = -4/5.

The sum of the 1st 2 terms of an exponential sequence is 135 and the sum of the 3rd and 4th terms is 60. Given that the common ratio is positive, calculate:
a. The common ratio and the 1st term
b. The least number of terms for which the sum exceeds 240.
The common ratio and the 1st term will be 2/3 and 81. And the least number of terms for which the sum exceeds 240 will be 11.
What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The amount of the first 2 terms of a remarkable grouping is 135 and the amount of the third and fourth terms is 60. Then the equations are given below.
a + ar = 136 ...1
ar² + ar³ = 60
r²(a + ar) = 60 ...2
From equations 1 and 2, then we have
r² x 135 = 60
r² = 60/135
r² = 4/9
r = 2/3
Then the value of 'a' is given as,
a + (2/3)a = 135
a = 81
Then the least number of terms for which the sum exceeds 240 will be given as,
Sₙ > [a₁ (1 - rⁿ)] / (1 - r)
240 > [81(1 - 0.66ⁿ)] / (1 - 0.66)
240 > 243(1 - 0.66ⁿ)

If I have a book that is 298 pages, and I read 20 pages a day, how long will it take me to read the entire book?
Also what is the formula to solve this problem problem!!
Answer:
Step-by-step explanation:
Given:
N₀ = 298 pages
N = 20 pages
You can apply the formula:
Number of days
D = [N₀ / N] + 1 = [298 / 20 ] + 1 =
= [14.9] + 1 = 14 + 1 = 15 day,
where the square brackets are the integer part of the number
If a book has 298 pages, and I read 20 pages a day, then it will take 15 days to read the entire book.
Total pages in the book= 298
Total pages that I daily read= 20
Then it will take 15 days to read the entire book.
The formula for this problem:
The solution to this type of problem can be figured out with the help of unitary method.
20 pages of a book can be read in = 1 day
1 page of a book can be read in = 1/20 days
298 pages of a book can be read in = 1/20×298 days = 14.9 days
But days cannot be 14.9, so it will be 15 days which is the nearest value of 14.9.

25.4 L
Step-by-step explanation:
Charles's Law
[tex]\sf \dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}\quad \textsf{(when pressure is constant and temperature is in kelvin)}[/tex]
where:
V₁ = first volume.T₁ = first temperature.V₂ = second volume.T₂ = second temperature.Given:
V₁ = 25 LT₁ = 25.0 °CT₂ = 30.0 °CConvert Celsius to kelvin.
Kelvin = Celsius + 273.15
[tex]\implies \sf T_1= 25 + 273.15 = 298.15 \;K[/tex]
[tex]\implies \sf T_2 = 30 + 273.15 = 303.15\; K[/tex]
Substitute the given values into the formula:
[tex]\implies \sf \dfrac{25}{298.15}=\dfrac{V_2}{303.15}[/tex]
[tex]\implies \sf V_2 =303.15 \cdot \dfrac{25}{298.15}[/tex]
[tex]\implies \sf V_2 =\dfrac{7478.75}{298.15}[/tex]
[tex]\implies \sf V_2 =25.41925205...L[/tex]
Therefore, the volume of air in the tire if the temperature increases to 30.0 °C is 25.4 L (nearest tenth).
