Answer:

Since magnesium = 2, and potassium = 1, magnesium is greater than potassium (2 > 1).

If we assign these elements letters, m and p respectively,

M > P

BC and DF are parallel lines. B is a point on AD and E is a point of DF. BD=BE. work out angle DBE give a reason. ITS ON MATHSWA
zloy xaker [14]

Answer:

(Angle DBE) ∠DBE = 50°

Step-by-step explanation:

It is crucial for us to be able to interpret plane geometry related question in order to solve them efficiently.

From the question given; we have analysed and come up with a diagrammatic expression and mathematical solution that clearly explains the question .

Given that

BC and DF are parallel lines.

B is a point on AD  

B is a point on AD

BD=BE

work out angle DBE and give a reason.

The diagram can be seen in the attached image below.

SInce ∠BD = ∠DE

Then triangle BDE is an isosceles triangle. In an isosceles triangle ; two sides are equal in length.

The sum of angles in an isosceles triangle = 180° (sum of angles in a triangle)

So;

∠BDE + ∠BED + ∠DBE = 180° (sum of angles in a triangle)

From the diagram; we will see that ∠ABC = ∠BDE  (corresponding angle)

Since ; ∠ABC is not given and which is needed to solve this question.

Let's just assume that ∠ABC is 65° , the main thing is to be able to interpret and understand the concept of the question.

Now;

Since

∠ABC = ∠BDE  

∠ABC  = 65°

∠BDE  = 65°

Again;

∠BDE + ∠BED + ∠DBE = 180° (sum of angles in a triangle)

∠BDE will be aso equal to  ∠BED ; this is because since the length of the opposite sides of the isosceles triangle are equal, their angles will also be equal.

Therefore;

65° + 65° + ∠DBE = 180° (sum of angles in a triangle)

130 ° + ∠DBE = 180° (sum of angles in a triangle)

∠DBE = 180° - 130°

∠DBE = 50°

Find the sum of the reciprocals of two consecutive even integers if the larger integer is x. please answer;-;​
Harman [31]

Step-by-step explanation:

Let the larger integer be x

Hence, the smaller integer = x-2

Hence,

Reciprocal of the x= 1/x

Reciprocal of x-2= 1/ x-2

Hence. their sum=

\frac{1}{x}  +  \frac{1}{x  - 2}  \\  =  \frac{x - 2 + x}{x(x - 2)} \\  =  \frac{2x - 2}{ {x}^{2}  - 2x}

What is the best approximation for the circumference of a circle with a diameter of 300 feet
garri49 [273]

Answer:

The answer is C=942.48

Step-by-step explanation:

You would figure this out by using the formula C=2πr.

So let's break this down.

Circumference (C) equals (=)  pi (π) times 2 times the radius of the circle.

Since the problem gave you the diameter which is the length from one side of the circle to the other, you have to divide the diameter in half. Which would give you a radius of 150.

Taking the 150 you would multiply 10*2*π.

Which would give you....(drumrollllll)

C=942.48

I hope this helps!!

p.s. have any more questions? Post them and comment the link!♥, Sadie
