Answer:

C) The resulting figure will be congruent to the original rectangle, because dilations with a scale factor of 1 have the same coordinates.

Step-by-step explanation: Multiplying any number by 1 will result in the same number, this applies to coordinates as well.

Find the area of the figure. Round to the nearest hundredth when necessary
dexar [7]

Answer:

  745.44 square mm

Step-by-step explanation:

The figure can be decomposed into ...

  • a semicircle of radius 12.5 mm
  • a rectangle 12.5 mm by 25 mm
  • a triangle 12.5 mm by 30 mm

The relevant area formulas are ...

  Semicircle: A = 1/2πr² = 1/2π(12.5 mm)² ≈ 245.437 mm²

  Rectangle: A = LW = (12.5 mm)(25 mm) = 312.500 mm²

  Triangle: A = 1/2bh = 1/2(12.5 mm)(30 mm) = 187.500 mm²

Total area of the figure is ...

  245.437 +312.500 +187.500 = 745.437 . . . mm²

The area of the figure is about 745.44 square mm.

The arched interior is comprised of a semi-circle and a rectangle. The diameter of the semi-circle is 20 inches. The length of t
kicyunya [14]

Step-by-step explanation:

A semicircle is a half circle. That means a semicircle will have half of the area of a circle. You might think that means it will have half the perimeter of a circle, but that is not true.

To make a semicircle, take any diameter of the circle. Remove one half of the circle along that diameter. You have a semicircle (half of a circle).

A semicircle is half the circumference of a full circle plus the diameter of a cricle,

In rectangle MNPQ with side MN = 16 in, point L is the midpoint of PQ and m∠QLM = 45°. Find the perimeter of the rectangle.
Marina86 [1]
See the attached figure

we know that
MN=16 in-------------> PQ=MN
PQ=16 in
<span>L is the midpoint of PQ-----------> distance QL=</span><span>PQ/2
QL=8 in
if </span>m∠QLM = 45°
then 
MQ=QL
MQ=8 in

Perimeter=[MN]*2+[MQ]*2=16*2+8*2=48 in

the answer is 48 in
