For AABC, AB = 6 and BC = 17. Which of the following is a possible length for AC?
Possible length of the third side of the Triangle must be between 11 and 23.
What is the Range of third side of Triangle ?As the third side of the triangle is between the sum of the sides and difference of the sides excluding both the numbers.
As triangle consist of three sides and it should must be in between two extreme values.
As by the property of Triangle
Third side should be less than sum of the sides and,
it should be greater than difference of the sides.
Sum of the sides = AB + BC = 6 + 17 = 23
Difference of the sides = 17 - 6 = 11
Then the third side will be between 11 and 23 excluding 11 and 23.

a cricket with 12 inch diameter is folded in half and folded again what is the area of the resulting shape
The area of the resulting shape if a circle with a 12-inch diameter is folded in half and then folded in half again is 28.26 square inches
What is the area of the resulting shape?Diameter of the cricket = 12 inchArea of a circle = πr²π = 3.14If a circle with a 12-inch diameter is folded into half and then folded into half again the circle will become a quadrant.
So,
The area of a quadrant is area of a circle divided by 4
Area of a quadrant = πr² / 4
Diameter of a circle = 2r
12 = 2r
divide both sides by 2
r = 6 inch
Area of the quadrant = 3.14 × (6)²/4
Area of the quadrant = (3.14 × 36) /4
Area of the quadrant = 113.04 / 4
Area of the quadrant = 28.26 square inches
In conclusion, the area of the quadrant is 28.26 square inches

What are the vertex and range of y = |3x + 6| − 4?
(−2, −4); −∞ < y < ∞
(−2, −4); −4 ≤ y < ∞
(0, −4); −∞ < y < ∞
(0, −4); −4 ≤ y < ∞
The vertex of y = |3x + 6| − 4 is (-2, -4) and the range of y = |3x + 6| − 4 is −4 ≤ y < ∞.
What is meant by vertex?A parabola's vertex is the location at which it crosses its axis of symmetry. The vertex will be the lowest point on the graph, or the point at the base of the "U"-shape, if the coefficient of the x2 term is positive.
The point is called the vertex (h, k). As we are all aware, a parabola's conventional equation is y = ax2 + bx + c. The bottom of the U-shaped curve is where the vertex is located if the coefficient x2 is positive, and the top of the curve is where the vertex is located if it is negative.
Given,
y = |3x + 6| − 4
The vertex of y = |3x + 6| − 4 is,
We have to find the absolute values zeroes,
3x+6=0
x= -2
To find the value of y, substitute x value in the above,
y= -4
(x, y)=(-2, -4)
Therefore, the vertex of y = |3x + 6| − 4 is (-2, -4)
And now,
The range of y = |3x + 6| − 4 is,
It can be defined by f(x)≥k
k= -4
f(x)≥ -4
Therefore, the range of y = |3x + 6| − 4 is −4 ≤ y < ∞.

suppose that for a science project you wanted to find exactly how much the length of a shadow changes during the day. how would you make this observation?
You should cast a shadow for a person or item at least three times and measure it each time to determine how the length of the shadow varies during the day.
The shape of an object always dictates the shape of its shadow. A shadow's size and shape can alter, though.
For instance, the location of the light source can induce these variations. The length of the shadow is influenced by the sun's position in the sky on a sunny day.
We can achieve the same effect indoors by adjusting the position of a flashlight reflecting on an object.
When the sun is low on the horizon, the shadows are lengthy, and when the sun is high, the shadows are considerably shorter.
So, To determine the change of length of object during the day, one should cast a shadow at least three separate times for a person or object and measure it each time

What are linear equations?A linear equation is a mathematical equation that describes a straight line. It is a first-degree polynomial equation, which means that the largest exponent of the variables is 1. Since a and b are constants and x and y are variables, linear equations have the general form ax+by=c. A straight line forms on a coordinate plane when the values of x and y fulfil the expression. The connection between two variables or the price of a product are two examples of real-world events that are frequently modelled using linear equations. Solving a linear equation entails determining the values of the variables that make the equation true. Different techniques, such graphing, substitution, or elimination, can be used to accomplish this.

Answer:

Step-by-step explanation:
If the gold steadily increased $400 over a four-month period, we need to figure out how much the gold increased each month.
400 ÷ 4 = 100
Now that we figured out that the gold steadily increased $100 every month, we now need to figure out what percent it grew.
1000 ÷ 100 = 10

What is an isosceles triangle?
An isosceles triangle in geometry is a triangle with two equal-length sides. It can be stated as having exactly two equal-length sides or at least two equal-length sides, with the latter definition containing the equilateral triangle as an exception.
3x - 5 = y + 12 (if two angles of a triangle are equal, the sides opposite
them are also equal) ------------(1)
Also, 3x - 5 = 5y - 4 (sides of a equilateral triangle are equal)
So, 5y - 4 = y + 12
5y - y = 12 + 4
4y = 16
y = 4
Now,
Put value of y in equation (1)
3x - 5 = y + 12
3x = 4 +12 + 5
3x = 21
x = 7

Joe has a 300 foot fence around his rectangular yard. The length is 10 feet more than the width. Which equation can you use to determine the dimensions?
The equation that used to determine the dimension is 2(2x+10) = 300 and the dimensions of the rectangular yard is 80 foot and 70 foot
Total length of the fence = 300 foot
Consider the width of the rectangular yard = x
The length of the rectangular yard = x + 10
The perimeter of the rectangle = 2(l + w)
Where l is the length and w is the width
Substitute the values in the equation
300 = 2(x+10 + x)
300 = 2(2x + 10)
4x + 20 = 300
4x = 300 - 20
4x = 280
x = 280/4
x = 70 foot
The length = x + 10
= 70 + 10
= 80 foot
Therefore, the equation is 2(2x+10) = 300 and dimensions are 80 foot and 70 foot

y = 2x + 5
y = -1/4x + 0.5
Substitute y = 2x + 5 in the equation y = -1/4x + 0.5
So, we have the following representation
-1/4x + 0.5 = 2x + 5
Collect the like terms
So, the equation becomes
2x + 1/4x = 0.5- 5

Answer: $178.25
Step-by-step explanation: Your balance on May 15 is $124.25. On May 20, you deposit $223.56, which increases your balance to $124.25 + $223.56 = $347.81. You then write a check for $89.56, which decreases your balance to $347.81 - $89.56 = $258.25. Finally, you withdraw $80.00 from an ATM on May 25, which decreases your balance to $258.25 - $80.00 = $178.25. Therefore, your current balance is $178.25.
