The ratio of the measure of the angles of a triangle is 1: 2: 3 . The length of the shortest side is 8 . What is the perimeter of the triangle?
The perimeter of the triangle is 37.86
Given,
The ratio of the measure of the angles of triangle = 1:2:3
Let the angles be taken as x, 2x, 3x.
Total angle of a triangle is 180°.
We can now find x.
x + 2x + 3x = 180°
6x = 180°
x = 180°/6 = 30°
x = 30°
2x = 2 × 30° = 60°
3x = 3 × 30° = 90°
Let the sides of the triangle be a, b, c.
The length of the shortest side is given = 8
Lets take a as 8.
We can use Trignometric Formulas here:
Trignometric Formulas:
sin θ = [tex]\frac{opposite side}{hypotenuse}[/tex]
cos θ = [tex]\frac{adjacent side}{hypotenuse}[/tex]
tan θ = [tex]\frac{opposite side}{adjacent side}[/tex]
By using sin rule we can find other sides.
That is,
sin 30° = opposite side / hypotenuse
sin 30° = a/b
sin 30° = 8/b
b = 8 × sin 30°
b = 16
Next,
sin 60° = opposite side / hypotenuse
sin 60° = c/16
c = sin 60° × 16
c = 13.86
Now we can find the perimeter of the triangle = a + b + c
= 8 + 16 + 13.86
= 37.86
The perimeter of the triangle is 37.86

what are two different methods for solving a real-world problem that can be represented by an equation
Subtraction Property of Equality and Addition Property of Equality are two different approaches to resolving a real-world problem that can be depicted by an equation.
What is defined as the Addition Property of Equality?When the identical quantity is added to the both sides of an equation, it generates an equivalent equation, according to the addition property of equality.
2 = 1+1, for example, is an equation given that both the right and left sides of the equal sign symbolize the number 2. However, by adding the number 3 to both sides, this same new equation 2 +3 = 1 + 1 + 3 is founded. As a result of the Addition Property of Equality, if a = b, then a + c = b + c.What is defined as the Subtraction Property of Equality?To maintain equality, if we deduct a number from one side of the equality, we must subtract the very same number from the opposite side of the equality.
Consider the equation X = Y. If a real number 'b' is deducted from the LHS of X = Y, we should then subtract b from Y, so X - b = Y - b. As a result, the formula is as follows:X = Y : X - b = Y - bThus, Subtraction Property of Equality as well as Addition Property of Equality are two different ways of solving a real-world problem that may be represented by an equation.

a. Create an algebraic expression that represents the amount of miles that Bobby & Jack
will run together. Simplify, if possible.
b. Determine how many miles they will run after 8 days.
From the situation described, it is found that:
a) The linear function that represents the amount of miles that Bobby & Jack will run together is T(x) = 2(4x + 5).
b) They will have run 74 miles after 8 days.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For both Bobby's and Jack's function, we have that:
The amount that they have ran is the intercept.The daily amount that they will run is the slope.Hence the functions for the number of miles they will have run after x days are given by:
B(x) = 4 + 3x.J(x) = 6 + 5x.The total amount is:
T(x) = B(x) + J(x)
T(x) = 4 + 3x + 6 + 5x
T(x) = 8x + 10.
T(x) = 2(4x + 5).
After 8 days, the number of miles they will have run is:
T(8) = 2(4 x 8 + 5) = 2 x 37 = 74.
They will have run 74 miles after 8 days.

Write the equation of the circle that passes through the given point and has a center at the origin. (Hint: You can use the distance formula to find the radius.) (√3, 0)
The equation of the circle that passes through the point (√3 , 0) and has a center at the origin is x^2 + y^2 = 3.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (√3 , 0).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(√3 - 0)^2 + (0 - 0)^2
radius= √3
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = √3

kilograms. Other shipments weighing 7700 kilograms have already been loaded into
the container. What is the greatest number of 130-kilogram crates that can be loaded
into the shipping container?
The maximum number of 130 kg crates that can be loaded into the shipping container is 137 which is calculated using linear inequality.
A linear inequality in mathematics is an inequality involving a linear function. One of the symbols for inequality is found in a linear inequality. It displays non-equal data in graph style.
An example of linear inequality is : 2x+8>18
Linear inequality can be represented using several symbols such as:
<,>,≥ and ≤.
Let us consider there are x number 130 kg crates.
The shipping container can take a maximum weight of 26500 Kilogram.
There is already 7700 kilograms of shipment loaded
Therefore we can write an linear inequality in x such as:
130x+7700 ≤ 256500
Subtracting 7700 from both sides we get:
130x+7700-7700 ≤ 25600-7700
or,130x ≤ 17900
Dividing both sides by 130
or, x ≤ 137.69....
Now we can say as the crates must be whole therefore the maximum number of 130 kg crates that the shipping container can hold is 137.

Assume an initial starting ft of 290 units, a trend (tt) of eight units, an alpha of 0.40, and a delta of 0.50. if actual demand turned out to be 278, calculate the forecast for the next period.
The forecast for the next period when the actual demand turned out to be 278 will be 294 units.
What is the forecast?The method of forecasting entails creating assumptions based on historical and current data. These might then be contrasted with what transpires.
Ft = 290, Tt = 8, α = 0.40, δ = 0.50, At = 278. Then the forecast for the next period will be
FITt = Ft + Tt
= 290 + 8
= 298 units
Ft + 1 = FITt + α(At − FITt)
= 298 + 0.40(278 − 298)
= 298 − 8
= 290 units
Tt + 1 = Tt + δ(Ft + 1 − FITt)
= 8 + 0.50(290 − 298)
= 8 − 4
= 4 units
FITt + 1 = Ft + 1 + Tt + 1
= 290 + 4
= 294 units
The forecast for the next period will be 294 units.

Solve each system by substitution. 3x+5y=13 , 2x + y = 4
The solution of the system of equations involving 3x + 5y = 13 and 2x + y = 4 is (1 , 2).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
3x + 5y = 13 (equation 1)
2x + y = 4 (equation 2)
Using the second equation, find the value of one variable, lets say y, in terms of the other.
2x + y = 4 (equation 2)
y = 4 - 2x
Substitute the equation of y to the first equation.
3x + 5y = 13 (equation 1)
3x + 5(4 - 2x) = 13
3x + 20 - 10x = 13
Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
3x + 20 - 10x = 13
3x - 10x = 13 - 20
-7x = -7
x = 1
Substitute the value of x in the equation of y.
y = 4 - 2x
y = 4 - 2(1)
y = 4 - 2
y = 2
Hence, the solution of the given system of equations is (1 , 2).
