The width of the rectangle is 40% of its length. What is the area of the rectangle?

A rectangle. The length is 20 feet.

Answers

Answer:

160in²

Step-by-step explanation:

40% = 0.4 = 4/10

The length is 20, 40% of that is (0.4)(20) = 8in

Length * width . = 20*8 = 160in²

The width of the rectangle is equal to 8 feet.

What is the area of the rectangle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the width of the rectangle is 40% of its length.

The width will be calculated as,

Answers

Answer:

Angle C is 54 degrees

Step-by-step explanation:

Angle B is 67 degrees and Angle A is 59 degrees. You add those two together to get 126 and subtract that from 180 to get the measure of Angle C

The measure of angle C is 54°.

From the diagram given, triangle A'B'C is a reflection of triangle ABC, therefore, triangle A'B'C' is similar to triangle ABC.

This implies that:

angle A = angle A' = 59°

angle B = angle B' = 67°

angle C = angle C' = ?

Therefore,

angle C = 180 - (angle A + angle B) ---> Sum of angles in a triangle equals 180°.

Plug in the values

angle C = [tex]180 - (59 + 67)\\[/tex]

angle C = 54°

Therefore, the measure of angle C is 54°.

1.) Given : S is the midpoint of RT; PR = PT

Prove : PRS = PTS


2.) Given : E is the midpoint of AB and CD

Prove: AEC=BED

Answers

Answer: 1.

Given: S is the midpoint of RT

PR=PT

To Prove: PRS=PTS

Step-by-step explanation:

If PR=PT in a triangle PRT, then the triangle is isosceles triangle.

Therefore,  ∠PRT=∠PTR (opposite angles of an isosceles triangle are equal)

In ▲PRS and ▲PTS

PR=PT

∠PRT=∠PTR

PS=PS (PS is common)

therefore, ▲PRS≅▲PTS

Therefore, ∠PRS=∠PTS

Hence proved.

Answer: 2.

Given: E is the midpoint of AB and CD.

To Prove: AEC=BED

Step-by-step explanation:

If AB and CD are the diagonals of rectangle, then

diagonals AB=CD,  sides AC=BD and AD=BC

In ▲AEC and ▲BED,

∠AEC=∠BED(vertically opposite angles)

AE=BE

AC=BD

therefore, ▲AEC≅▲BED

Therefore,  ∠AEC=∠BED

Hence Proved.

The proofing of each part should be explained below.

Prove:

a.

In the case when

PR=PT in a triangle PRT,

So the triangle is an isosceles triangle.

Therefore,  ∠PRT=∠PTR

Now

In ΔPRS and ΔPTS

PR=PT

So,

∠PRT=∠PTR

So,

PS=PS (PS is common)

ΔPRS≅ΔPTS

Hence proved.

2.

In the case when AB and CD are the diagonals of the rectangle,

So,

diagonals AB=CD,  sides AC=BD and AD=BC

In ΔAEC and ΔBED,

So,

∠AEC=∠BED

That means

AE=BE

AC=BD

therefore, ΔAEC≅ΔBED

Hence Proved.

Rotate the vector (5,1) 90°

Answers

Answer:

(-1, 5)

Step-by-step explanation:

this is correct

The new coordinates of the vector (5,1) after rotating it 90° clockwise about the origin would be (-1,5).

What is a transformation?

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

Rotating a vector 90° clockwise in a 2D coordinate system can be accomplished by "flipping" the vector's x and y coordinates and then negating one of them.

In this case, the original x-coordinate is 5 and the y-coordinate is 1.

When we negate the x-coordinate and swap the positions of x and y, we get the new coordinates of (-1,5).

The graph of an absolute value function contains the points (1, 2), (0, 0), and (–1, 2). Shawn thinks the function this graph represents is f(x) = 2|–x|. Brielle thinks the function this graph represents is f(x) = 2|x|. Determine who is correct and explain why.

Answers

Answer:

Shawn and Brielle are correct, since absolute has the following property: [tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]

Step-by-step explanation:

Both Shawn and Brielle are correct, because the absolute value has the following property:

[tex]|a| = |-a|[/tex], [tex]a\in \mathbb{R}[/tex]

Which means that [tex]|x|[/tex] and [tex]|-x|[/tex] gives the same result.

Answer:

Both Shawn and Brielle are correct. The absolute value parent function is symmetric with respect to the y-axis, and the absolute value of negative x is a reflection across the y-axis, so the graph of these two functions would look identical. Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.

Answer-So the dimensions of the rectangle are width is 4 m and length is 11 m

 

Step-by-step explanation:

Equation for Perimeter of a rectangle: Perimeter = 2W + 2L

 

Defining the variables, let

 

Width = x

Length = 2x+3 (3 more than twice the width)

 

Plugging everything into the equation

 

30= 2(x) + 2(2x+3)  using the distributive property,

30=2x+4x+6  combining like terms

30=6x+6  subtracting 6 from both sides,

24=6x  divide both sides by 6

4=x  This means that the width is 4 m

 

To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved for

L=2(4)+3

L=8+3 = 11 m

 

So the dimensions of the rectangle are width is 4 m and length is 11 m
