The first side of a triangle is 3cm longer than the second. The third side is twice as long as the second. The perimeter is 31cm. Find the length of each side.
Answer:
7 cm ; 10 cm ; 14 cm
Step-by-step explanation:
x = y + 3
z = 2y
x + y + z = 31
y + 3 + y + 2y = 31

The graph of the linear function passes through the points (2,44) and (5,80). What is the equation of this function?
y=?x+?
The equation for the given linear function is y = 12m + 20.
What is a linear equation?A linear equation in two variable has the general form as y = ax + by + c, where a, b and c are integers and a, b ≠ 0.
It can be represented as a straight line on a graph.
The given points for the linear function are (2, 44) and (5, 80) respectively.
The slope can be obtained as,
m = (80 - 44)/(5 - 2)
= 36/3
= 12
Substitute the value of m in the general form y = mx + c to obtain,
y = 12x + c
Now, substitute x = 2 and y= 44 in the above expression as,
44 = 12 × 2 + c
=> c = 44 -24
=> c = 20
Thus the linear function can be written in the form of equation as,
y = 12m + 20
Hence, the equation of the function for the given case is y = 12m + 20.

a) The probability of rolling a total of 5 is 1/9.
b) If a pair of fair dice 360 times, then 40 times you will get a total of 5.
What is probability?
Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.
The number of 5 in the table is 4.
The total number of outcomes is 6 × 6 = 36
The number of outcomes of favorable event is 4.
Total number of outcomes is 36.
The probability getting total of 5 after rolling the pair of dice is
=4/36
Divide the denominator and numerator by 4:
= 1/9
If 360 time the pair of dice rolled, the number of times to get total 5 is

The swimming pool was on sale for $1206.2, which is 18.5% less than its initial $1429.35 cost.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent symbol (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
Here,
Sale price after discount=$1206.2
Discount percent=18.5%
Original price=1206.2+18.5%*1206.2

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is given as

Now , the values of the function f ( x ) can be determined when we substitute for the values for x in the equation
So , in order to find f ( 0 ) , substituting the value for x as x = 0, we will get the value for the function
a)
when x = 0
The equation is f ( x ) = 2x + 5
f ( 0 ) = 2 x 0 + 5
f ( 0 ) = 5
So , the value of f ( 0 ) = 5
b)
when x = 1
The equation is f ( x ) = 2x + 5
f ( 0 ) = 2 x 1 + 5
f ( 0 ) = 7
So , the value of f ( 0 ) = 7
c)
when x = 5
The equation is f ( x ) = 2x + 5
f ( 0 ) = 2 x 5 + 5
f ( 0 ) = 15
So , the value of f ( 0 ) = 15

The function f(x) is 4x5 – 3x has exactly 5 roots according to the Fundamental Theorem of Algebra.
How to find number of roots ?According to the Fundamental Theorem of Algebra, a polynomial function of degree n has exactly n roots (also known as zeros).In other words, if f(x) is a polynomial function of degree n, then there exist n values of x, called roots or zeros, that satisfy the equation f(x) = 0.The Fundamental Theorem of Algebra is important because it guarantees the existence of solutions to polynomial equations, which are equations that have the form f(x) = 0, where f(x) is a polynomial function.In this case, the polynomial function is f(x) = 4x^5 - 3x, which is of degree 5. Therefore, the function has exactly 5 roots according to the Fundamental Theorem of Algebra.The correct answer is therefore d) 5 roots.
