why do bones break???
Answer: Bones break because so much force is applied onto them at a singular moment, more than can be handled. Most commonly from falls where you hit your bone in a specific spot.
Bones can break, also known as a fracture, due to a variety of reasons. Here are some common causes:
Trauma: A sudden force or impact, such as a fall, can cause a bone to break.
Overuse: Repeated stress on a bone over time can cause a stress fracture, which is a small crack in the bone.
Medical Conditions: Certain medical conditions, such as osteoporosis, cancer, or infections, can weaken bones and make them more susceptible to fractures.
Vitamin and Mineral Deficiencies: Insufficient levels of calcium, vitamin D, and other minerals necessary for strong bones can increase the risk of fractures.
The severity of a fracture can vary depending on the force of impact and the strength of the bone. Some fractures may only cause minor pain and swelling, while others may require surgery and a prolonged healing process.
It is important to seek medical attention if you suspect a fracture as prompt diagnosis and treatment can help prevent complications and promote healing. Treatment options for a fracture may include immobilization, casting, surgery, or physical therapy, depending on the severity and location of the break.
A regular hexagon is shown below. Find the value of x. (11x + 21)° X =
The given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon
What is hexagon ?
A hexagon is a six-sided polygon, which is a two-dimensional geometric shape with straight sides. The word hexagon comes from the Greek words "hexa" meaning "six" and "gonia" meaning "angle."
To find the value of x in the regular hexagon, we can start by noting that the interior angles of a regular hexagon are all congruent and measure 120 degrees.
Next, we can see that the given angle (11x + 21)° is an interior angle of the hexagon. Therefore, we can set this angle equal to 120 degrees and solve for x:
11x + 21 = 120
11x = 99
x = 9
Therefore, the value of x is 9.
Note that we can check our answer by substituting x = 9 into the original equation:
11x + 21 = 11(9) + 21 = 120
Therefore, the given angle measures 120 degrees, which is indeed an interior angle of a regular hexagon

Dakota is able to drive his car 32.5 miles per gallon of gasoline. Write and solve an inequality that could be used to determine the minimum number of gallons of gasoline Dakota would need to drive 117 miles to his brother's house. Then interpret the solution. Explain your reasoning. Input Field 1 of 1 Skip to input field.
Answer:
Step-by-step explanation: first if you do x/32.5 ≤ 117 = 3802.5 and also we know that 1 mile= 32.5, so if you take 32.5 * 117 it also equals 3802.5
so it will take him a minimum of 3802.5 gallons to drive 117 miles
Dakota would need at least 3.6 gallons of gasoline to drive 117 miles to his brother's house.
What is the inequality?A statement that compares two numbers or expressions using an inequality symbol, such as (less than), > (greater than), (less than or equal to), or, is known as an inequality in mathematics (greater than or equal to).
Let x be the volume of gasoline required for Dakota to travel 117 miles to his brother's home. The minimum value of x can be calculated using the inequality shown below:
x ≥ 117 / 32.5
Here, we calculate the bare minimum amount of gasoline Dakota would require to travel 117 miles by dividing the whole distance (117 miles) by the miles per gallon (32.5 miles/gallon).
The inequality is reduced to: x ≥ 3.6
Dakota would therefore require 3.6 gallons of fuel to travel 117 miles to his brother's house.

The fraction of the euro is 8/100
one Euro will cost in 8 rands
When we talk about exchange rates, we're essentially talking about the value of one currency compared to another. In this case, we're comparing the South African rand to the euro.
We know that one South African rand is valued at 0.125 of one euro. To figure out what fraction of the euro one South African rand is worth, we can simply divide the value of one rand by the value of one euro:
1 rand ÷ 0.125 euro = 8/100 euro
So, one South African rand is worth 8/100 or 0.08 (which is equivalent to 8%) of one euro.
To calculate what one euro would cost in rands, we can use the inverse of the exchange rate we were given:
1 euro ÷ 0.125 rand/euro = 8 rand
So, one euro would cost 8 South African rand.

Answer:
1st page:
To determine if Jason and Arianna made a mistake in their solution, we can examine the slopes and y-intercepts of the two equations.
The first equation, 5x - 3y = -1, can be written in slope-intercept form as y = (5/3)x + 1/3, where the slope is 5/3 and the y-intercept is 1/3.
The second equation, 3x + 2y = 7, can be written in slope-intercept form as y = (-3/2)x + 7/2, where the slope is -3/2 and the y-intercept is 7/2.
To solve the system of equations, we need to find the point of intersection of the two lines. We can see from the slopes that the lines are not parallel, so they must intersect at some point. However, the slopes are not perpendicular either, so they do not intersect at a right angle.
By graphing the two equations on the same coordinate plane, we can see that the point of intersection is (2, 2), not (4.04, 7.31) as Jason and Arianna calculated. Therefore, they must have made a mistake in their solution.
In summary, we can tell that Jason and Arianna made a mistake in their solution by examining the slopes and y-intercepts of the two equations and graphing them to find the actual point of intersection.
2nd page:
To determine if Jason and Arianna made a mistake in their solution, we can graph the two linear equations on the same coordinate plane and look for the point of intersection.
We can begin by rearranging the equations into slope-intercept form:
5x - 3y = -1 → y = (5/3)x + 1/3
3x + 2y = 7 → y = (-3/2)x + 7/2
Now we can graph the two lines. We can plot two points for each line and connect them with a straight line to obtain the graphs.
For the first equation, when x = 0, we get y = 1/3. When x = 3, we get y = 6/3 = 2. Plotting these two points and connecting them, we get:
Graph of the first equation
For the second equation, when x = 0, we get y = 7/2. When x = 2, we get y = 1/2. Plotting these two points and connecting them, we get:
Graph of the second equation
We can see from the graphs that the lines intersect at the point (2, 2), not at (4.04, 7.31) as Jason and Arianna found. Therefore, they must have made a mistake in their solution.
In summary, we can tell from the graphs of the equations that Jason and Arianna must have made a mistake because the lines do not intersect at the point they found.
3rd page:
We can determine if there is a unique solution to the system of linear equations by examining the slopes of the two equations.
The slope of the first equation, 5x - 3y = -1, can be found by rearranging the equation into slope-intercept form y = (5/3)x + 1/3. We can see that the slope of the line is positive and not equal to the slope of the second equation, which is -3/2.
Similarly, the slope of the second equation, 3x + 2y = 7, can be found by rearranging the equation into slope-intercept form y = (-3/2)x + 7/2. Again, we can see that the slope of the line is negative and not equal to the slope of the first equation, which is 5/3.
Since the slopes of the two lines are not equal, they will intersect at a unique point. In other words, there is only one solution to the system of equations.
Therefore, we can conclude that there is a unique solution to the system of linear equations given by 5x - 3y = -1 and 3x + 2y = 7, based on the slopes of the graphs of the equations in the system.

Answer:
sin(B)/b = sin(A)/a
sin(B)/12 = sin(58)/a
a = 12(sin(58)/sin(B))
Now we can use the Law of Cosines to find the remaining sides of the triangle:
a^2 = b^2 + c^2 - 2bc*cos(A)
a^2 = 12^2 + c^2 - 2(12)(c)*cos(58)
c^2 - 24c*cos(58) + 144 - a^2 = 0

c = 12*cos(58) ± sqrt(576 - 576*sin(58)^2 - 576(1.03*(12/sin(180 - 58 - B)))))^2)
c = 12*cos(58) ± sqrt(576 - 576*sin(58)^2 - 576(1.03*(12/sin(122 - B)))))^2)
Now we can solve for c using the two possible values of B:
B = arcsin(b*sin(A)/a)
B = arcsin(12*sin(58)/a)
B = arcsin(12*sin(58)/(12*sin(58)/sin(B)))
B = arcsin(sin(B))
B = 58
or
B = 180 - arcsin(b*sin(A)/a)
B = 180 - arcsin(12*sin

The solution of the system of linear equations on the graph is one solution at (1, −2).
How to determine the solution of equations' graphs?Analyzing the intersection of the graphs of a system of linear equations on the coordinate plane will reveal how many solutions there are. The system has a single solution if the graphs meet at a single location. The system cannot be solved if the graphs are parallel and do not intersect. The system has an unlimited number of solutions if the graphs coincide, or overlap.
From the graph we observe that the two lines intersect at the point (1, -2).
The point where the lines intersect is thus the solution of the system of linear equations on the graph.
Hence, the solution of the system of linear equations on the graph is one solution at (1, −2).

Ben is incorrect because…
All of Ben's expressions are erroneous since none of them equal the number 108 degrees. The correct equation is (n-2) x 180 / n.
What is the equation of interior angle in a regular polygon?A polygon is a geometric object with two dimensions and a finite number of sides. A polygon's sides or edges are created by connecting end to end segments of a straight line to create a closed shape. Vertex or corners refers to the intersection of two line segments, which produces an angle.
In a regular polygon, where n is the number of sides, the formula for measuring an interior angle is (n-2) x 180 / n.
An internal angle in a pentagon has a measure of (5-2) x 180 / 5 = 108 degrees.
Substituting the angle in Ben's expression:
xᵒ + (x + 40)° + (2x - 30)° + 3(x - 40)° + 3x°
9x - 27° = 108
We observe that none of the value of x results in 108 degrees.
Hence, all of Ben's expressions are erroneous since none of them equal the number 108 degrees.

The figure's perimeter, rοunded tο the nearest hundredth, is rοughly 51.39 feet.
What is perimeter?The tοtal length οf a twο-dimensiοnal shape's bοundary οr οuter edge is knοwn as its perimeter. It is the space encircling the periphery οf a shape. Yοu add up the lengths οf all a shape's sides tο determine its perimeter. The length units used tο measure the sides have an impact οn the perimeter measurement units.
given:
The lengths οf all the edges must be added up in οrder tο determine the figure's perimeter.
The figure is made up οf a rectangle with a length οf 3 feet and a breadth οf 9 feet, twο semicircles with a diameter οf 9 feet each, and twο semicircles.
A semicircle with a diameter οf 9 feet has the fοllοwing circumference:
C = 1/2 * pi * d
C = 1/2 * 3.14 * 9
C = 14.13 feet
The circumference οf bοth semicircles taken tοgether is thus:
P = 2*14.13P = 28.26 feet
The rectangle's perimeter is as fοllοws:
P(rectangle) is equal tο 2 * (length + width).
P(rectangle) = 3 + 9 * 2
24 feet P(rectangle)
As a result, the figure's οverall perimeter is as fοllοws:
Semicircles: P = P + P (rectangle)
P = 28.26 + 24
P = 52.26 feet
The figure's perimeter, rοunded tο the nearest hundredth, is rοughly 51.39 feet.
Anοther figure with the same perimeter as the οne given can be drawn in a variety οf ways.

Ina makes cakes in a pan shaped like a rectangular prism. The base of the pan is an 8-inch by 12-inch rectangle, and the volume of the pan is 288 cubic inches. Find the surface area of a cheesecake baked in this pan
Answer:
312 square inches
Step-by-step explanation:
To find the surface area of a cake baked in a rectangular pan with an 8-inch by 12-inch base and a volume of 288 cubic inches, we need to find the dimensions of the pan. We can do this by dividing the volume by the area of the base, which gives us the height of the pan. Once we know the height, we can use the dimensions of the base and the height to find the surface area of the cake.
TIME REMAINING 17:48 The graph of f(x) = x2 is translated to form g(x) = (x – 2)2 – 3. On a coordinate plane, a parabola, labeled f of x, opens up. It goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). Which graph represents g(x)? On a coordinate plane, a parabola opens up. It goes through (0, 1), has a vertex at (2, negative 3), and goes through (4, 1).
The graph of g(x) is a parabola that opens up, goes through (0, 1), has a vertex at (2, -3), and goes through (4, 1).
What is parabola ?
A parabola is a U-shaped curve that is formed by graphing a quadratic function. In other words, a parabola is the set of all points in a plane that are equidistant from a fixed point (called the focus) and a fixed line (called the directrix).
The graph of g(x) can be obtained by translating the graph of f(x) = x^2 to the left by 2 units and down by 3 units.
The vertex of g(x) is obtained by subtracting 2 from the x-coordinate and subtracting 3 from the y-coordinate of the vertex of f(x). Thus, the vertex of g(x) is (2, -3).
The point (-2, 4) on f(x) is translated left by 2 units to (−4, 4) on g(x) and then down by 3 units to (−4, 1). The point (2, 4) on f(x) is translated left by 2 units to (0, 4) on g(x) and then down by 3 units to (0, 1).
Therefore, the graph of g(x) is a parabola that opens up, goes through (0, 1), has a vertex at (2, -3), and goes through (4, 1).

Answer:

Step-by-step explanation:

Answer:
A: x
Step-by-step explanation:
So with problems like this when it saids f(g(x) it wants you to plug those values in. In some cases you have a value where the x is but you don't so you can't solve g(x) so you move on to the next step. You plug in g(x)= x-1/2 everywhere there is a x in f(x). So our equation would be 2(x-1/2) + 1. Then you solve by canceling the 2 by dividing it out so we would have x-1 +1. Then you combine like terms which -1 +1 is 0 so our final answer would be x.

3. The SA of box with lid is 294.7972 inch².
What is Surface Area?The area is the territory covered by a shape or figure, whereas the perimeter is the distance covered by the shape's outside boundary. The unit of area is the square unit or unit², while the unit of perimeter is the unit.
Given:
length = 13.2 inch
Height = 10.5 inch
And, Surface Area used = 295.02 inch²
Using the Formula
SA = 2lw + 2wh + lh
SA = 2w (l +h) + lh
295. 02 = 2w ( 13.2 + 10.5) + (13.2)(10.5)
147.51 = w x 24 + 138.6
8.91 = 24w
w = 0.37125 inch
SA of box with lid
= 2( lw+ wh + lh)
= 2( 13.2 x 10.5 + 10.5 x 0.37125 + 0.37125 x 13.2)
= 2(138.6 + 3.8981 + 4.9005)
= 2 x 147.3986
= 294.7972 inch²
