Step-by-step explanation:
This triangle is right angled so we know it has a 90-degree angle at the corner with the box.
All angles add up to 180 in a triangle.
180 = 90 + 48 + x
180 - 90 = 48 + x
90 - 48 = x
x = 42

What does the seven-year time limit mean?
The so-called "Seven Year Rule," which is derived from Section 157(4) of the Planning and Development Act 2000, is not the same as this. This indicates that once seven years have passed after the start of the development, local authorities cannot issue enforcement notices for an unauthorized development.It is time to speak with a lawyer or the organization that insured your title if there is a sizable discrepancy between where two deeds set a property border. It's possible that a mistake was made when drafting one of the deeds. To try to pinpoint the time the issue happened, someone may need to conduct research on both attributes. The mistake can affect multiple previous landowners.Remember that the majority of surveys indicate the property lines on the deed. Usually, the poll doesn't directly state that a certain action is improper. Ideally, the position of the property line is agreed upon in both documents.

Ivan was at the beach. He wanted to spend $12 or less on a beach bike rental. The company he chose
to rent from charged an initial fee of $5 and an additional $0.45 per mile he rode.
a. Write an inequality for this situation. Let x represent the number of miles ridden.
b. What is the greatest number of whole miles Ivan can ride without going over his spending
limit?
Answers
Using a linear function, it is found that:
a. The inequality for this situation is: 5 + 0.45x ≤ 12.
b. He can ride at most 15 miles without going over the limit.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).For the context of this problem, the slope and the intercept are defined as follows:
The slope is the cost per mile, hence m = 0.45.The intercept is the flat cost, the renting fee of b = 5.Hence the cost function, considering x miles, is given as follows:
C(x) = 0.45x + 5.
He wanted to spend $12 or less on a beach bike rental, hence the inequality that models this situation is given by:
C(x) ≤ 12.
5 + 0.45x ≤ 12.
The inequality is solved similarly to an equality, isolating the variable and finding the range of values, hence the solution is found as follows:
0.45x ≤ 7
x ≤ 7/0.45
x ≤ 15.6 miles.
The greatest whole number of miles is of 15 miles, as for 16 miles, the cost would be above $12.

Where does the graph of y= -2x + 1 intersect the x-axis?
Answers
The graph intersects the x-axis at ( 1/2 , 0) .
A cartesian coordinate system, which uses signed distances between two fixed perpendicular oriented lines and the point measured in the same unit of length, uniquely identifies any point in a plane by a pair of numerical coordinates.
The origin of each reference coordinate line, known as an x-axis or y-axis of the system or simply an axis (plural axes), is the intersection of the ordered pairs (0, 0).The coordinates can also be determined by looking at the locations of the perpendicular projections of the point onto the x- axis and y -axis, which are shown as signed distances from the origin.We know that at the x-axis the value of y is 0 .
Now substituting the value of y in the equation of the graph we get :
y = - 2x + 1
at y = 0 ,
0 = -2x + 1
or, -1 = -2 x
or, x = 1 / 2
Hence the co-ordinate of the point where the graph passes through x-axis is ( 1/2 , 0 ) .

Question 8A: Mr. Sowers wants to purchase expo markers for his classroom. He has a budget of $35. A four pack of markers costs $5.49, including tax. Write and solve an inequality, using x for the variable, to solve for the number of packs of markers Mr. Sowers can purchase. Copy/paste one of the following inequality symbols to help you write your inequality: ≤ < ≥ >
Answers
The number of packs of markers that Mr. Sowers can purchase is 6.
How many packs can he buy?The maximum amount that Mr. Sowers can spend is $35. This means that the amount can either by $35 or less than $35. Thus, the inequality sign that would be used is the less than or equal to sign, ≤ .
total amount spent on the packet of markets ≤ budget
(cost of one packet x number of packets) ≤ $35
$5.49x ≤ $35
In order to determine the value of x, divide both sides of the equation by 5.49
x ≤ $35 / 5. 49

what is 7 1/5 divided by 8 in fraction form and as a mixed number
Answers
7 1/5 divided by 8 in fraction form is 36 / 40 = 9/ 10 and in decimal form = 0.9
A fraction is a numerical expression expressing a portion of the whole. There are two parts: a numerator and a denominator. The denominator is the total number of pieces that make up the whole, while the numerator is the number of equally sized portions of the whole. For instance, in the percentage of 3/8 has a denominator of 8 and a numerator of 3.
We have been given that -
7 1/5 divided by 8
Rewrite as
(36/5) / 8
36 / 5×8
Multiplying 5 with 8 and we get
36 / 40
Follow these steps to convert an incorrect fraction to a mixed number: Subtract the denominator from the numerator. The quotient's whole number component should be written down. Write the leftover amount on top of the original denominator.
36/ 40 in decimal form = 0.9
0.9 = 0.9 × 10 /1 × 10
= 9 / 10
Hence, When 7 1/5 is divided by 8, the result is 36/40 (9/10) and 0.9 (in decimal notation).

Pythagoras theorem - The length of the third side is 6.71unit
What is Pythagoras theorem ?
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a key relationship in Euclidean geometry between a right triangle's three sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
The Pythagoras theorem's equation is as follows:
H² = P² + B²
The triangle's third side will be the following length:
Let x represent the triangle's third side's length.
9² = 6² + x²
81 = 36 + x²
x² = 45
x = 6.708
x = 6.71 units

3. Sales increase $1,000 as ads increase by $1,000.
5. A positive slope infers a positive correlation.
What is defined as the slope?The slope of a line measures its steepness as well as direction.The slope of a line is defined as the change throughout y coordinate in relation to the transformation in x coordinate.The net change in y coordinates is y, while the net change in x coordinates is x.So m represents the transition in y coordinate throughout relation to the shift in x coordinate. m = Δy/Δx, where, m is the slope.Positive correlation:
A positive correlation is a correlation that exists between two variables which move in the same direction. A positive correlation exists whenever one variable decreases while the other increases, or when one variable increases whereas the other decreases.From the scatter points on graph, its clear that the slope which is 15 is a positive correlation.
Now, to find the slope we see the change in y with respect to x.

Two cars leave from a place at the same time they travel in opposite directions one at 62 KM per hour the other at 48 KM per hour how long will it take before they are 550 KM apart
Answers
If two cars leaves from a place at the same time they travel in opposite directions and the speed of the first and second cars are 62 km per hour and 48 km per hours respectively , 5 hours will take before they are 550 km apart
The speed of the first car=62 km per hour
The speed of the second car=48 km per hour
Two cars leave from a place at the same time they travel in opposite directions
The relative speed of the car = Speed of the first car - (- Speed of the second car )
=62-(-48)
=110 km per hour
Time take = Distance between the two cars / Relative speed of the two care

Write an equation for each situation, in terms of t,t, and determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved.
Answers
The number of weeks when Salma and Henry would have the same amount of money is 20 weeks.
How many weeks would they have the same amount?The form of the equations that represent the total amount of money saved is :
Total amount in the account = initial amount in the account + (amount added each week x number of weeks)
SS = $35 + ($8 x tt)
SS = $35 + $8tt
HH = $95 + ($5 x tt)
HH = $95 + $5tt
When they have the same amount in their account, the two equations woud be equal.
HH = SS
$95 + $5tt = $35 + $8tt
$95 - $35 = $8tt - $5tt

How to Create and Graph the Equation of a Line?To create the equation of a line, we need to determine the following:
Y-intercept/starting value = b
Slope of the line/rate of change = m
The ordered pair of the y-intercept or starting value is represented as (0, b), where b is the value of y on the y-axis where the line intercepts the y-axis and x = 0 at this point.
These values can be substituted into y = mx + b, which represents the equation of the line in slope-intercept form.
From the information given, we have:
Y-intercept/starting value (b) = 100
Slope of the line/rate of change (m) = 9
To write the equation of the line, substitute m = 9 and b = 100 into y = mx + b:
y = 9x + 100

Answers
Step-by-step explanation:
that only means we need to put the given values into every place, where the variable is used in the expression.
this is straight forward.
x² for x = -9 means
(-9)² = 81
you remember, a² = a×a.
and when a is negative, this is then the multiplication of a negative number with a negative number, and that result is positive.
so, a square operation always delivers a positive result for real numbers as input, no matter if the input was already positive or negative.
