On solving the provided question, we can say that The area of the arrow is equal to A = A1 + A2 = 68+12 = 80 cm sq.
What is area?The size of an area on a surface can be expressed as an area. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a planar region or planar region refers to the area of a form or planar layer. The total amount of space filled by a planar (2-D) surface or shape of an object is known as its area. Draw a square on a piece of paper using a pencil. a character with two dimensions. The area of a shape on paper is the space it takes up. Imagine that the square is composed of more compact unit squares.
The area of rectangle is equal to
A1 = LW
L = 17cm
W = 4cm
A1 = 68 cm sq.
The area of triangle is equal to
A2 = 1/2*b*h

Explain what AB means and what AB/ means. How are these two meanings related?''
AB vector is a vector whereas AB bar is a line segment.
What is a vector ?
The vectors are described as an object containing both significance and course. Vector describes the motion of an item from one point to any other. Vector math may be geometrically picturised via the directed line segment.
The duration of the phase of the directed line is known as the value of a vector and the angle at which the vector is inclined shows the path of the vector. The start line of a vector is referred to as “Tail” and the finishing factor (having an arrow) is referred to as “Head.”
The difference is in their names itself.
AB vector is a vector whereas AB bar is a line segment.
A vector has a direction and a magnitude while a line segment ( scalar ) has only magnitude.
Therefore, AB vector is a vector whereas AB bar is a line segment.

The following equation has an error in one of the operations.
2(x−4y)+3y=2x+11y
Which answer would correct the error?
1. Change 2(x−4y)+3y to 2(x+4y)−3y.
2. Change (x−4y) to (x+4y).
3. Change 2x+11y to 2x−11y.
4. Change 2(x−4y)+3y to 2(x−4y)−3y.
answer is 2 because if we expand the bracket we get 2x–8y+3y which is 2x–5y but if it was 2(x+4y) it would be equal to 2x+8y+3y therefore being 2x+11y
What is the difference in rainfall from the wettest and driest months ?
The difference in rainfall between the wettest and driest months is the amount of precipitation.
What do you mean by precipitation?Precipitation refers to any form of moisture that falls from the atmosphere to the ground, including rain, snow, sleet, hail, and other forms of precipitation. Precipitation is an important aspect of the Earth's water cycle, as it provides the water that replenishes rivers, lakes, and aquifers, and sustains the growth of plants and animals.
The amount of precipitation that falls in a given area can vary widely, depending on many factors such as geography, temperature, and prevailing weather patterns. For example, areas near the equator tend to receive more rainfall than areas located closer to the poles, and areas with high elevations tend to receive more snow than areas that are closer to sea level.
The distribution of rainfall and other forms of precipitation across a region can also be affected by the prevailing winds, air masses, and topographical features. For example, mountainous areas may receive more rainfall due to the prevailing winds and the way that air masses interact with the terrain.
The difference in rainfall between the wettest and driest months is the amount of precipitation that occurs in the wettest month minus the amount of precipitation that occurs in the driest month. This difference can vary greatly depending on the location and climate of a region.

What is a bar graph?A bar graph is a graphical depiction of information, amounts, or numbers using bars or strips. They are utilized to contrast and compare various data types, frequencies, or other measurements of several categories of data.
On the graph, there are two axes. The numerical data is displayed against the category data on one axis, which is used to depict the numerical values.
Given the graph which shows the rainfall of the wettest and driest months,
here red blocks are for the driest months and blue blocks show the wettest months,
From the graph, we can see that the wettest month has a rainfall height of 2.3 inches
The driest month has a rainfall of -1.67 inches
So the difference between the two will be;
2.3 - (-1.67)
= 2.3 + 1.67 = 3.97 inches

Solve the inequality: −5x−4≤6
x > -2
Step-by-step explanation:Inequalities compare the values of 2 expressions.
Solving for x
To solve the inequality, we need to isolate x. First, add 4 to both sides.
-5x ≤ 10Then, divide by 5.
-x ≤ 2Finally, divide both sides by -1. When multiplying or dividing an inequality by a negative, switch the direction of the sign.
x > -2Interpreting the Answer
Verbally, the answer is that x is greater than or equal to -2. This means that any x-value greater than -2 (including -2 itself) will make the original inequality, −5x−4 ≤ 6, true. For example, let's plug in 0.
-5(0) - 4 ≤6-4 ≤ 6This statement is true, which proves our answer is correct.
Describe how the graph of the function is a transformation of the original function f.
y=f(x+16)
The graph of the function y = f(x + 16) is a transformation of the original function f. This transformation has shifted the graph of f to the right by 16 units on the x-axis. This means that the value of x in the original function has been increased by 16, which has an effect on the corresponding value of y in the transformed function.
For example, if the point (a, b) is on the graph of f, then the point (a + 16, b) will be on the graph of y = f(x + 16). The x-coordinate of the point has been increased by 16, and since the transformation is a horizontal shift, the y-coordinate remains unchanged.
In summary, the graph of y = f(x + 16) is a reflection of the graph of f about the vertical axis. The transformation has the effect of shifting the graph to the right, but preserving the shape and overall form of the original function.

In this example we are given
[tex]\angle A =27.2 \textdegree\\\angle C=115.5 \textdegree\\c=76.0[/tex]
Angle B
The sum of the interior angles in a triangle add up to 180º. Given 2 angles, we can evaluate the 3rd.

Given that, an amount $8000, is invested at 5% and 7%, with annual interest is $490,
For this we will establish the a system of equations,
x + y = 8000......(i)

Sort the data: 41, 41, 43, 43, 45, 50, 52, 53, 54, 62, 63, 63, 67, 75, 97
Find the median (Q2): 53
Split the data set into two parts: Q1 (25th percentile) and Q3 (75th percentile)
Q1: 41, 41, 43, 43, 45, 50, 52, 53
Q3: 54, 62, 63, 63, 67, 75, 97
Find the median (Q1) of Q1 and the median (Q3) of Q3:
Q1 = 45
Q3 = 63
Finally, calculate the IQR by subtracting Q1 from Q3:
IQR = Q3 - Q1 = 63 - 45 = 18
So, the interquartile range of the given data set is 18. This means that 50% of the data falls within a range of 45 + 18 = 63 and 45 - 18 = 27.
