The sum of three lengths of a fence ranges from 45 to 60 inches. Two side lengths are 9 and 18 inches. If the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side.
a. 9 ≤ x ≤ 18
b. 18 ≤ x ≤ 33
c. 36 ≤ x ≤ 42
d. 45 ≤ x ≤ 60
The solution to a compound inequality to show the possible lengths of the third side is 18 ≤ x ≤ 33.
What is Compound Inequality?Two or more inequalities are connected together with or or and to form a compound inequality (also known as a combined inequality).
A value must only make one aspect of an inequality true in order to be the solution to an or inequality. An inequality's solution must make both portions true in order to be effective.
According to the given values;
given parameters are
Range = 45 to 60 inches
Sides = 9, 18 and x
The sum of the three sides is
sum=9 + 18 + x
Evaluate
Sum = 27 + x
Recall that
Range = 47 to 60 inches
So, we have
45 ≤ 27 + x ≤ 60
Subtract through by 27
So, we have
18 ≤ x ≤ 33
Hence, the solution to a compound inequality to show the possible lengths of the third side is 18 ≤ x ≤ 33.

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.
100 points and brainliest
There are some differences in the process of constructing a inscribed square and a hexagon inside a circle.
When constructing a square, we start with a circle. Then draw its diameter through the center of the circle. Now putting compass on end points of this diameter, measuring more than half the length of diameter on the compass, draw 4 arcs above and below the diameter. So we get a perpendicular bisector of the diameter. In total, we get 4 points on the circle. Joining the adjacent points, we get the inscribed square.
When constructing the regular hexagon, start drawing a circle. Put the compass on a point on the circle and measure the radius on it. Now draw an arc on the circle. Putting compass on this new point on the circle draw another arc. Continuing like this, we get a total of 6 arcs giving 6 points on the circle. Join the adjacent points to get an inscribed regular hexagon.
So the differences in constructing the square and the regular hexagon are:
Diameter is used in square whereas radius is enough for the regular hexagonPerpendicular bisector is constructed for square while regular hexagon does not need one.For a square,4 arcs giving 4 points on the circle are needed. But for a regular hexagon 6 arcs giving 6 points are there.Learn more about inscribed shapes at https://brainly.com/question/21502832

What is the area, in square meters, of the shape below? Express your answer as a fraction in simplest form.
Area = 5/12 m².
For image see the attachment below-
Area of Triangle - A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. A triangle is also a polygon. The above figure is a triangle denoted as △ABC. Some real-life examples of triangles include sandwiches, traffic signs, cloth hangers, and a rack in billiards.
The basic formula to find the area of a triangle is,
Area of triangle = 1/2 (b × h);
where b = base and
h = height of the triangle.
Now , we have been given that -
Base =5/3 m
Height = 1/2 m
Find out area of the triangle .
The area of a triangle = 1/2 x base x height
Put the values in formula
area of a triangle = 1/2 x 5/3 x 1/2
area of a triangle = (1x5x1)/ (2x3x2)
area of a triangle = 5/12 m².

BIRDHOUSES Ebony can build 0.7 birdhouse in 1 day. How many birdhouses can she build in 10 weeks?
Step-by-step explanation:
0.7 birdhouses in 1 day.
how many in 10 weeks ?
for that we need to know how many days are in 10 weeks.
1 week = 7 days
assuming that she is working on the birdhouses also on weekends, that means 10 weeks = 10×7 = 70 days.
and that means she can build
0.7 × 70 = 49 birdhouses in 10 weeks.
now, if she works only Monday to Friday on the birdhouses, then that means
1 week = 5 days
and 10 weeks = 10×5 = 50 days.
and that means she can build
0.7 × 50 = 35 birdhouses in 10 weeks.
if there is really no other information about that, I would use the usual 7 days per week and the first solution (49).

Which of the following ordered triples is the solution to the system of equations?
2x − y − z = −1
3x + y − z = 2
x + y − 5z = −8
Answer:
1,1,2
Step-by-step explanation:
The solution to the given system of equations are:{ x = 1, y = 1, z = 2} which is the corrrect answer would be option (A).
What is an equation?The equation is defined as a mathematical statement with at least two terms that contain variables or values that are equal.
We have been given the system of equations as:
2x − y − z = −1
3x + y − z = 2
x + y − 5z = −8
Isolate the term of x in the equation 2x − y − z = −1, and we get
x = (- 1 + y +z)/2
Substitute the value of x = (- 1 + y +z)/2 in the above both equations,
3(- 1 + y +z)/2 + y − z = 2
(- 1 + y +z)/2 + y − 5z = −8
Simplify the equation to you get,
(5y + z - 3) / 2 = 2
(3y - 9z - 1) / 2 = -8
Isolate the term of y : (5y + z - 3) / 2 = 2 ⇒ y = (-z +7 )/5
Substitute the value of y = (-z +7 )/5 in the equation (3y - 9z - 1) / 2 = -8
(3(-z +7 )/5 - 9z - 1) / 2 = -8
Simplify the equation to you get,
8(-3z + 1)/d = -8
Isolate the term of z : 8(-3z + 1)/d = -8 ⇒ z = 2
Substitute the value of z = 2 in the equation y = (-z + 7) / 5 to simplify to get
⇒ y = 1
Substitute the values of y = 1 and z = 2 in the equation x = (-1 + y + z) / 2 to simplify to get
⇒ x = 1
The solution to the given system of equations are:
{ x = 1, y = 1, z = 2}

Which equation represents a line through (4, -6) and (0, 2)?
Answer: C
Step-by-step explanation: Substitute four and zero in each of the choices and see if the sum becomes negative six and two, respectively. If it does, then the equation represents the line.
Third equation substitution:
x = 4
y = -2(4) + 2
y = -8 + 2
y = -6
x = 0
y = -2(0) + 2
y= 0 + 2
y = 2
Therefore, the answer is C.

What set of transformations is performed on triangle ABC to form triangle A′B′C′? (1 point)

A 180 degree counterclockwise rotation about the origin followed by a translation 5 units up
b
A 270 degree counterclockwise rotation about the origin followed by a translation 5 units up
c
A translation 5 units to the left followed by a 180 degree counterclockwise rotation about the origin
d
A translation 5 units to the left followed by a 270 degree counterclockwise rotation about the origin
The set of transformations that is performed on triangle ABC to form triangle A′B′C′ is C. A translation 5 units to the left followed by a 180 degree counterclockwise rotation about the origin.
What is a translation?A translation is a geometric transformation when each point in a figure, shape, or space is moved in a specific direction by the same amount. A translation can also be thought of as moving the coordinate system's origin or as adding a constant vector to each point.
In this case, it can be seen that the shape was rotated counterclockwise twice. That's 90° × 2 = 180°
Therefore, the transformation that is performed on triangle ABC to form triangle A′B′C′ is a translation 5 units to the left followed by a 180 degree counterclockwise rotation about the origin.
