Answer:

Perimeter of the dilated rectangle = 23.2 m

Step-by-step explanation:

If a point is dilated by a scale factor = k

Coordinates of the image point after dilation will follow the rule,

(x, y) → (kx, ky)

From the given rule,

(x, y) → (0.4x, 0.4y)

Which reveals that the figure has been dilated by a scale factor = 0.4

Length of the rectangle = 12 m

Width of the rectangle = 17 m

If the given rectangle is dilated by a scale factor of 0.4,

Length of the image rectangle = 12 × 0.4 = 4.8 m

Width of the image rectangle = 17 × 0.4 = 6.8 m

Perimeter of a rectangle = 2(length + width)

Therefore, perimeter of the image rectangle = 2(4.8 + 6.8)

                                                                           = 23.2 m

Step-by-step explanation:

The statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

Rectangles a shape with four sides and having internal angles of  [tex]90^0[/tex]. Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.

[tex](a)[/tex]  The opposite sides are  equal and parallel to each other.

[tex](b)[/tex]  The diagonals bisect each other but not at [tex]90^0[/tex].

[tex](c)[/tex]   Diagonals are equal in length.

[tex](d)[/tex]   The diagonals of rectangle are congruent.

[tex](e)[/tex]   The sum of interior angles is equal to [tex]360^0[/tex] .

[tex](f)[/tex]   Each interior angle is equal to [tex]90^0[/tex].

[tex](g)[/tex]   The angles of a rectangle are all congruent.

[tex](h)[/tex]    Opposite angles of a rectangle are congruent.

So, from the above mentioned properties we can assume that statements mentioned in options  [tex](A),(B),(C),(E)[/tex]  are true about rectangles.

Hence, we can say that the statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

Answer: She ran a total distance of 16 kilometers

Step-by-step explanation:

Average speed  by Serana is given as =  Distance  /Time

But Average speed  = 8 kilometers per hour

Time = 2hours

Distance = Average speed x Time

=8 km/h x 2hours

= 16 kilometers

Answer:

52% Copper, 28% Zinc, 20% Nickel

Step-by-step explanation:

Copper is 13 out of 13+7+5 = 25

13/25 = 52%

Zinc is 7 out of 25 so 28%

Nickel is 5/25 = 20%

Answer:

Step-by-step explanation:

Part A

Since, BDFHJ is a regular pentagon,

Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]

= [tex]\frac{(5-2)\times 180}{5}[/tex]

= 108°

Since, ∠ABC ≅ ∠JBD [Vertical angles]

Therefore, m∠ABC = m∠JBD = 108°

Part B

m∠JBD + mCBD = 180° [Linear pair of angles]

108° + m∠CBD = 180°

m∠CBD = 180 - 108

m∠CBD = 72°

Similarly, m∠BDF + m∠CDB = 180°

m∠CDB + 108° = 180°

m∠CDB = 180 - 108

             = 72°

In ΔCBD,

m∠BCD + m∠CDB + m∠DBC = 180°

m∠BCD + 72° + 72° = 180°

m∠BCD = 180° - 144°

              = 36°

Answer: The charge is equal to 1.602*10^(-17) C

Step-by-step explanation:

The elementary charge (the smallest charge that exists) is the charge of one proton (or the magnitude of the charge of a single electron), and it is equal to:

c = 1.602*10^(-19) C.

Where C stands for coulombs,

Then a charge of 100 elementary charges is equal to 100 times the charge of a single electron, this is:

Charge = 100*( 1.602*10^(-19) C) = 1.602*10^(-17) C

Answer:

452.16

Step-by-step explanation:

i got it right on test

The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

We have to given that;

Height of cylinder = 6 cm

And, Diameter of cylinder = 12 cm

Hence, We get;

⇒ Radius of cylinder = 12 / 2 = 6 cm

We know that;

The formula for the total surface area of a given cylinder whose radius is r and height is h is,

TSA = 2πr (h + r)

Hence, We get;

TSA = 2πr (h + r)

TSA = 2 × 3.14 × 6 (6 + 6)

TSA = 37.68 × 12

TSA = 452.16 cm²

Thus, The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

Answer: 5 cartons

Step-by-step explanation:

If the Chef wants to have a total of at least 50 eggs and each carton contains 12 eggs, divide 50 by 12 to find out the number of cartons needed and then round the number up:

= 50 /12

= 4.16

Round it up to the nearest 1:

= 5 cartons

This will ensure that there is at least 50 eggs because 5 * 12 = 60 eggs.
