a quarry needs to ship a marble block weighing 10000 pounds. if the cost of shipping is 110 per ton, how much will shipping cost?
The cost of shipping the marble block is 550.
The total weight of the marble block is 10,000 pounds.We need to convert the weight from pounds to tons.Unit conversion is the process of converting various units of measurement for the same amount, often using multiplicative conversion factors that modify the measured quantity value without affecting its effects.1 ton equals 2000 pounds.The total weight of the marble block in tons is 10000/2000.The total weight of the marble block is 5 tons.The cost of shipping is 110 per ton.The total cost of shipping the marble block = 5 * 110.The total cost of shipping the marble block is 550.To learn more about unit conversion, visit :

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:

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.
Note: I skipped to the third equation because the other equations are false.

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.

Say you are given the graph of the line y = -x. Write the equation of the line that is perpendicular to the given line and goes through the point (-8, 2).
Linear equations are often organized in slope-intercept form: [tex]y=mx+b[/tex]
m = slopeb = y-interceptTo find a linear equation, we often first solve for the slope, and then solve for the y-intercept algebraically.
To find the slope of a perpendicular line, we must find the negative reciprocal of the slope of the reference line.
Solving the Question
We're given:
Reference line is [tex]y=-x[/tex]Perpendicular line passes through [tex](-8,2)[/tex]1) Find the slope of the reference line
We can rewrite the reference line to be clearer in slope-intercept form:
[tex]y=-1x+0[/tex]
This means that -1 is the slope.
2) Find the slope of the perpendicular line
The negative reciprocal of -1 is 1. Therefore, the slope of the perpendicular line is 1. Plug this into slope-intercept form:
[tex]y=x+b[/tex]
3) Solve for the y-intercept of the perpendicular line
[tex]y=x+b[/tex]
Plug in the given point (-8,2) and solve for b:
[tex]2=-8+b\\b=2+8\\b=10[/tex]
Therefore, the y-intercept of the perpendicular line is 10. Plug this back into our original equation:
[tex]y=x+10[/tex]
Answer[tex]y=x+10[/tex]

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

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

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).
