The required length of the cut edge will be 50 cm. which is the correct answer would be an option (D).

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

The piece of paper from one corner to the other, as shown figure.

Let the length of the cut edge would be x cm, which is equal to the hypotenuse in the given right triangle.

According to Pythagoras's theorem,

⇒ c² = a² + b²  ....(i)

As per the given question, we have

c = x, a = 40 cm and b = 30

Substitute the values in the above formula, and solve for x

⇒ x² = 40² + 30²

⇒ x² = 1600 + 900

⇒  x² = 2500

⇒  x² = 50²

⇒  x = 50

Therefore, the required length of the cut edge will be 50 cm.

Answer:

p = 0.35

q = 0.65

n = 7

Step-by-step explanation:

To calculate the distribution, we have the following values;

p = 35% = 35/100 = 0.35

q = 1-p = 1-0.35 = 0.65

n = 7

Answer:

≈10502.7

Step-by-step explanation:

Hi there!  

»»————-　★　————-««

I believe your answer is:  

160π cubic units.

»»————-　★　————-««  

Here’s why:

The formula for volume of a cylinder is:

[tex]V=\pi r^2h[/tex]

[tex]\boxed\text{Key:}\\\\[/tex][tex]\boxed{\text{Key:}}\\\\\text{R - Radius}\\\\\text{H - Height}[/tex]

⸻⸻⸻⸻

We are given:

⸻⸻⸻⸻

We will replace the 'r' with '4' and we will replace the 'h' with '10'.

⸻⸻⸻⸻

There are two ways to express the answer, either an exact answer in terms of pi or an approximation using 3.14 for pi.

For this answer, I will use the exact terms.

⸻⸻⸻⸻

[tex]\boxed{\text{Finding the Volume of the Cylinder:}}\\\\V=\pi 4^210\\\\-------\\\rightarrow V=4^2*10*\pi \\\\\rightarrow V=16*10*\pi\\\\\boxed{V=160\pi}[/tex]

The answer should be [tex]\boxed{160\pi\text{ units} ^3.}[/tex]

Answer:

A Dramatic change in appearance or form

Step-by-step explanation:

Answer:

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Mathematical transformations describe how two-dimensional figures move around a plane or coordinate system. A preimage or inverse image is the two-dimensional shape before any transformation.

Answer:

[tex]y=-3x+5[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y= -3x -5[/tex]

With the given line, we can identify clearly that -3 is in the place of m, making it the slope. Because parallel lines have the same slopes, the slope of the line we're currently solving for would also be -3. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-3x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-3x+b[/tex]

Plug in the given point (1,2) and isolate b

[tex]2=-3(1)+b\\2=-3+b[/tex]

Add 3 to both sides

[tex]2+3=-3+b+3\\5=b[/tex]

Therefore, the y-intercept of the line is 5. Plug this back into [tex]y=-3x+b[/tex]:

[tex]y=-3x+5[/tex]

I hope this helps!

Answer:

D

Step-by-step explanation:

22/11 = 2

77/11 = 7

110 /11 = 10

121/11 = 11

In each case, when you divide the input by 11 you get the output.

The rule is to divide the input by 11.

Answer: D

Answer:

y=7x-3

Step-by-step explanation:

(1,4). y=mx+b or 4=7 × 1+b, or solving for b: b=4-(7)(1). b=-3.

(3,18). y=mx+b or 18=7 × 3+b, or solving for b: b=18-(7)(3). b=-3.

hence, y=7x-3

This is the slope intercept form for the points, not sure if you wanted it in standard form or point slope form...

Answer:

y = 7x

Step-by-step explanation:

[tex]\frac{18-4}{3-1}[/tex] = [tex]\frac{14}{2}[/tex] = 7

y = 7x

If that curve is 110 then the angle is as well.

+Answer:

You are lying more then telling the truth.

Step-by-step explanation:

At first, it was a lie but a coincidence happened, so it is more lying in my opinion.

Answer:

CD  ║ EF and ED is transversal, hence

We can see that:

Since the angles CDB and ADB sum to 180, these are consecutive interior angles, therefore AB and CD are parallel lines.

PU and QT are parallel and PT is transversal, therefore:

Now find the missing angles of ΔQTP

Now, we see that:

As  ∠TPQ ≅ ∠SQR  these angles are corresponding angles.

Therefore PT and SQ are parallel lines.
