<h3>Answer: first choice, \text{ABCD} \cong \text{A'B'C'D'}</h3>

Explanation:

Any rotation will keep the angles the same measure. The amount of rotation doesn't matter, and the center of rotation doesn't affect things either. So if angle A is something like 87 degrees, then angle A' is also 87 degrees. Therefore, angles A and A' pair up and correspond. The same can be said about the other pairs of angles.

So quadrilateral ABCD is congruent to quadrilateral A'B'C'D'. The order of the letters is important so that they align and match up properly.

Answer:

ABCD ≅ A'B'C'D'

Step-by-step explanation:

When a figure is rotated, its orientation stays the same. This means that the pre-image and the image are labeled in the same direction. Therefore, ABCD ≅ A'B'C'D'

Manuela is having mugs made for a fundraiser. The Cup Company will make them for $4 each plus a $30 set-up charge. Mugs Are Us w
amm1812

Answer:

The price will be the same for both companies at 60 mugs

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the rate of change
  • b is the fixed amount

Assume that the number of mugs is x and the total cost of them is $y

∵ The Cup Company will make them for $4 each plus a $30

   set-up charge

∴ The cost per mug = $4

∴ m = 4

∴ The fixed amount = $30

∴ b = 30

∵ x is the number of mugs

∵ y is the cost of them

→ Substitute the values of m and b in the form of the equation

∴ y = 4x + 30 ⇒ (1)

∵  Mugs Are Us will make them for $4.50 each with no set-up charge

∴ The cost per mug = $4.50

∴ m = 4.5

∴ The fixed amount = 0

∴ b = 0

∵ x is the number of mugs

∵ y is the cost of them

→ Substitute the values of m and b in the form of the equation

∴ y = 4.5x + 0

∴ y= 4.5x ⇒ (2)

∵ The price be the same for both companies

→ Equate the right sides of (1) and (2)

∴ 4.5x = 4x + 30

→ Subtract 4x from both sides

∵ 4.5x - 4x = 4x - 4x + 30

∴ 0.5x = 30

→ Divide both sides by 0.5

∴ x = 60

∴ The price will be the same for both companies at 60 mugs
