Answer:
D. 20 centimetersStep-by-step explanation:
Surface area of a cone = surface area of a circle = pi r^2
250 = pi r^2
[tex]r = \sqrt{ \frac{250}{2} } = 5 \sqrt{5} \: cm[/tex]
Because the height (h) of the cone is double the length of its radius
Then
h = 2r
[tex]h \: = 2 \times 5 \sqrt{5} = 10 \sqrt{5} = 22.36 \: cm[/tex]
So it'll equal approximate 20 cmwhich equation represents the slope intercept form of the line when the y intercept is (0,-6) and the slope is -5
The values into the slope-intercept form, we have y = -5x - 6
The slope-intercept form of a linear equation is given by:
y = mx + b
where 'm' represents the slope of the line, and 'b' represents the y-intercept.
In this case, the y-intercept is (0, -6), which means that the line crosses the y-axis at the point (0, -6).
The slope is given as -5.
Therefore, substituting the values into the slope-intercept form, we have:
y = -5x - 6
This equation represents the line with a y-intercept of (0, -6) and a slope of -5.

3. In ∆ JAM, which of the following statement is always TRUE?
The option that shows the missing angles in the triangle is:
Option C: m∠1 < m∠4
How to identify the missing angle?We know that the sum of angles in a triangle is 180 degrees.
Therefore looking at the given triangle, we can say that:
m∠1 + m∠2 + m∠3 = 180°
We also know that the sum of angles on a straight line is 180 degrees and as such we can say that:
m∠3 + m∠4 = 180°
By substitution we can say that:
m∠4 = m∠1 + m∠2
Thus:
m∠1 < m∠4

1. Only some rectangles are parallelograms.
2. Parallelograms have 2 pairs of parallel sides.
3. So, only some rectangles have 2 pairs of parallel sides.
1. All rectangles are parallelograms.
2. Parallelograms have exactly 1 pair of parallel sides.
3. So, all rectangles have exactly 1 pair of parallel sides.
The correct statement about rectangles is:
1. All rectangles are parallelograms.
2. Parallelograms have exactly 1 pair of parallel sides.
3. So, all rectangles have exactly 1 pair of parallel sides.
A rectangle is a type of parallelogram that has additional properties. By definition, a rectangle is a quadrilateral with four right angles. This means that opposite sides of a rectangle are parallel. Since all four sides of a rectangle are right angles, it follows that a rectangle has exactly 1 pair of parallel sides.
Option 1 states that only some rectangles are parallelograms, which is incorrect. All rectangles are parallelograms because they have opposite sides that are parallel.
Option 2 states that parallelograms have 2 pairs of parallel sides, which is also incorrect. Parallelograms have exactly 2 pairs of parallel sides, not 4. A rectangle is a special type of parallelogram that has additional properties such as all angles being right angles.
Option 3 states that only some rectangles have 2 pairs of parallel sides, which is incorrect. All rectangles have exactly 1 pair of parallel sides, not 2. Having 2 pairs of parallel sides would make a shape a parallelogram, not a rectangle.
Therefore, the correct statement is that all rectangles are parallelograms and have exactly 1 pair of parallel sides. 1,2,3 are correct.

how to draw the 6th term .
To draw the 6th term, represent it visually within the context of the pattern or sequence from which it is derived.
To draw the 6th term, we need to understand the context or pattern from which the term is derived.
Drawing the term usually involves representing the elements or characteristics of the pattern in a visual form.
Without specific information about the pattern, we can provide a general approach to drawing the 6th term.
Identify the Pattern:
Determine the sequence or pattern from which the 6th term is derived.
It could be a numerical sequence, a geometric pattern, or any other pattern.
For example, if the pattern is a number sequence of multiples of 3, the first few terms would be 3, 6, 9, 12, 15, and so on.
Visualize the Pattern: Based on the identified pattern, visualize how the elements change or progress from term to term.
This could involve drawing a diagram, a graph, or any visual representation that captures the pattern.
Consider using a coordinate grid, a number line, or any other suitable visual aid.
Locate the 6th Term:
Use the information from the pattern and the visualization to determine the specific position or value of the 6th term.
In our example of multiples of 3, the 6th term would be 18.
Draw the 6th Term: Finally, represent the 6th term in your chosen visual form.
This could mean marking the position on a number line, plotting a point on a graph, or incorporating the value into a diagram.
Note that the specific method of drawing the 6th term will depend on the nature of the pattern and the context in which it is given.
Providing more details about the pattern would allow for a more accurate and specific visual representation of the 6th term.

help me please. identify the errors in the proposed proofs
The errors in the proposed statement to prove by contradiction that 3·√2 - 7 is an irrational number, is the option;
To apply the definition of rational, a and b must be integersWhat is proving by contradiction?Proving by contradiction is an indirect method of proving a fact or a reductio ad absurdum, which is a method of proving a statement by the assumption that the opposite of the statement is true, then showing that a contradiction is obtained from the assumption.
The definition of rational numbers are numbers that can be expressed in the form a/b, where a and b are integers
The assumption that 3·√2 - 7 is a rational number indicates that we get;
3·√2 - 7 = a/b, where a and b are integers
Therefore, the error in the method used to prove that 3·√2 - 7 is an irrational number is the option; To apply the definition of rational, a and b must be integers. This is so as the value 3·√2 - 7 is a real number, which is also an irrational number, thereby contradicting the supposition.

How do I find GBA and show all the work
Answer:
Angle ACB = 44°
There are two ways to solve it. Both are right
Solution number 1
From triangle ABC
angle BAC = 180°-(102° +44°) = 36°
Because BG is parallel with AC
Then angle GBA = angle BAC = 34°Another solution
The sum of angles in the shape AGBC = 360°
So angle GBC = 360 - (90 + 90 + 44 + 102) = 34°the drawing shows an isosceles triangle
40 degrees
can you find the size of a
Angle "a" in the given isosceles triangle is 40 degrees.
To find the size of angle "a" in the isosceles triangle with a 40-degree angle, we can use the properties of isosceles triangles. In an isosceles triangle, the two equal sides are opposite the two equal angles.
Since the given angle is 40 degrees, we know that the other two angles in the triangle are also equal. Let's call these angles "b" and "c." Therefore, we have:
b = c
Since the sum of the angles in a triangle is always 180 degrees, we can write the equation:
40 + b + c = 180
Since b = c, we can rewrite the equation as:
40 + b + b = 180
Combining like terms, we have:
2b + 40 = 180
Subtracting 40 from both sides, we get:
2b = 140
Dividing both sides by 2, we find:
b = 70
Therefore, both angles "b" and "c" are 70 degrees.
Now, we can find angle "a" by subtracting the sum of angles "b" and "c" from 180 degrees:
a = 180 - (b + c)
= 180 - (70 + 70)
= 180 - 140
= 40
