Answers
each numbered angle is
1. right angle
2. obtuse angle
Road signs, often known as traffic signs, are posted along the side of roadways or above them to inform and direct drivers. Simple wooden or stone milestones were the oldest types of signs. Later, directional signs with arms were developed, such as the fingerposts used in the United Kingdom and their wooden equivalents in Saxony. Since the 1930s, as traffic volumes have increased, many nations have adopted pictorial signs or have similarly standardized and simplified their signs in an effort to overcome linguistic barriers and improve traffic safety. Such pictorial signals are typically based on international norms and use symbols (often silhouettes) in place of words. These signs were initially created in Europe and have since been adopted in varied degrees by the majority of nations.

The solution to the composite functions are as follows:
f(g(x)) = x² + 4x + 4 / 2g(f(x)) = x² / 2 + 2How to solve composite function?The composite functions can be solved as follows:
f(x) = x² / 2
g(x) = x + 2
Therefore,
f(g(x)) = (x + 2)² / 2
f(g(x)) = (x + 2)(x + 2) / 2
f(g(x)) = x² + 2x + 2x + 4 / 2
f(g(x)) = x² + 4x + 4 / 2
Therefore,
g(f(x)) = x² / 2 + 2
g(f(x)) = x² / 2 + 2

Sakura is making a mobile. She has a spool of twine that she cuts into

twine in lengths in order from shortest to longest.
the lengths?
Answers
In order to compare the lengths from the shortest to the longest, we need to convert all the fractions into decimals.
We are given the different lengths of the spool of twine that is being cut.
We have those lengths as:
5 / 6 foot
0.75 foot
4 / 5 foot.
To compare the lengths from the shortest to the longest, we need to first convert all the fractions into decimals.
So, we get that:
5 / 6 foot = 0.83 foot
4 / 5 foot = 0.80 foot
Now, we can arrange the lengths from the shortest to the longest.
0.75 foot, 0.80 foot, o.83 foot.
Therefore, we get that, in order to compare the lengths from the shortest to the longest, we need to convert all the fractions into decimals.

In a class of 45 students, there are 15 girls, what is the percentage of the class are boys
Answers
Answer:
75%
Step-by-step explanation:
To find the percentage of boys in the class, we must know how many boys are in the class.
The class has a total of 45 students. 15 of those students are females, so we know to 45 - 15 is the number of boys.
45-15=30
So now we now that there are 30 boys. To be more specific, 30 boys out of the 45 students. We can look at this as a fraction, which can be changed to a percentage/decimal. ([tex]\frac{30}{45}[/tex])
[tex]\frac{30}{45}[/tex] converted to a percentage is 75. This means that the percentage of boys in the class is 75%

Answers
The graph of saving function f(x) = 40 - 1.25x has been plotted with a slope of -1.25.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
Given the function,
f(x) = 40 - 1.25x
Now to plot it we need to put x = 0
f(0) = 40 so y-intercept is (0,40)
Now keep f(x) = 0
Then 0 = 40 - 1.25x
x = 40/1.25 = 32
So x-intercept is (32,0)
So plot a straight line using points (0,40) and (32,0).
Hence "The graph of saving function f(x) = 40 - 1.25x has been plotted".

VA and VB are slant height (hypotenuse)
VM=perpendicular height
AM and BM are base
VA=√VM² + AM²

This is the graph of y= x2 + 4x + 7 what is the range of this function?
Answers
The range of the function y = x^2 + 4x + 7 is y >= 3
How to determine the range of the function?The equation of the function is given as
y = x^2 + 4x + 7
Start by differentiating the above function
So, we have
y' = 2x + 4
Set the above equation to 0
So, we have
2x + 4 = 0
Divide through the equation by 2
So, we have
x + 2 = 0
Evaluate the like terms:
x = -2
Substitute x = -2 in y = x^2 + 4x + 7
y = (-2)^2 + 4(-2) + 7
Evaluate the expression
y = 3
The leading coefficient of the equation y = x^2 + 4x + 7 is positive
This means that the vertex is a minimum
So, the range is
y >= 3
Hence, the range of the function y = x^2 + 4x + 7 is y >= 3
