Which cross-sectional shapes do you find the most surprising? Explain why.
Zanzabum

By critically observing the cross-sections of the three-dimensional object I used, a cone is the cross-sectional shape I find most surprising.

<h3>The cross-section of a three-dimensional object?</h3>

In this exercise, you're required to use an online tool to investigate and determine the cross-sections of three-dimensional objects such as pyramids, cylinders, cones, etc., by passing different planes through them.

By critically observing the cross-sections of the three-dimensional object I used, a cone is the cross-sectional shape I find most surprising because rotating the slice around Y produced a circular curve that transitioned into a parabolic curve.

Is the following statement a good definition? Why? An obtuse angle is an angle whose measure is greater than 90°.
Virty [35]

180° measures more than 90°, so according to the given statement, a plane angle is also an obtuse angle, and that is incorrect. From that, we conclude that the statement is not a good definition.

<h3>Is the following statement a good definition? </h3>

The given statement is:

"An obtuse angle is an angle whose measure is greater than 90°."

This is the common, but incorrect, definition for obtuse angles.

We know that an angle that measures 180° is called a plane angle and by definition, a plane angle is not an obtuse angle.

And the angles larger than 180° (and smaller than 360°) are the reflex angles.

Now, 180° measures more than 90°, so according to the given statement, a plane angle is also an obtuse angle, and that is incorrect. From that, we conclude that the statement is not a good definition.

The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of
Snowcat [4.5K]

Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

x+y+z=855

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

x + y + z = 855

substituting y + z = x / 1.5 in the equation

x+\frac{x}{1.5}=855

Multiply both sides by 1.5

x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5

1.5x+x=1282.5

2.5x=1282.5

Divide both sides by 2.5

\frac{2.5x}{2.5}=\frac{1282.5}{2.5}

x = 513

Therefore, the value of x = 513
