Answer: F.) 7 triangles

Step-by-step explanation:

Congruent means completely equal in side lengths and angles. Think of this weird figure like 4 triangles that are see through and are covering a diamond underneath

Of those 4 "see through triangles", there are 3 equal to ΔABC

Now on the diamond underneath, there is another 4. Its hard to actually explain what I mean, but take two triangles from that dimaond. Theyre gonna be congruent to ΔABC.

That's 4 + 3 = 7 total triangles

Rectangle divided into four rectangles. The perimeters of rectangle #1, #2, #3 #4 are 10 cm, 20 cm, 28 cm and 18 cm respectively

Neporo4naja [7]

Answer:

The perimeter of the big rectangle is 38 cm

Step-by-step explanation:

Rectangle 1 and rectangle 2 share the same width, let their width be a cm while Rectangle 3 and rectangle 4 share the same width, let their width be b cm

Rectangle 1 and rectangle 3 share the same length, let their length be x cm while Rectangle 2 and rectangle 4 share the same length, let their length be y cm

The perimeter of a rectangle = 2(length + breadth).

For rectangle 1:

Perimeter = 2(a + x) = 10

a + x = 5 1)

For rectangle 2:

Perimeter = 2(a + y) = 20

a + y = 10 2)

For rectangle 3:

Perimeter = 2(b + x) = 28

b + x = 14 3)

For rectangle 4:

Perimeter = 2(b + y) = 18

b + y = 9 4)

Adding equations 1, 2, 3 and 4 gives:

a + x + a + y + b + x + b + y = 5 + 10 + 14 + 9

a + a + b + b + x + x + y + y =38

2a + 2b + 2x + 2y = 38

2((a + b) + (x + y)) = 38

For the big rectangle, let its width = c = a + b and its length be d = x + y

The perimeter of the big rectangle = 2 (c + d)

Therefore:

2((a + b) + (x + y)) = 38

2(c + d) = 38 cm = The perimeter of the big rectangle

The perimeter of the big rectangle is 38 cm

FInd the volume of the cylinder in terms of Pi.

Luba_88 [7]

The formula for the area of a cylinder is $\pi$ $r^{2}$ ×h

First, we do not have to worry about pi because we are leaving our answer in terms of it so we can move on to the radius squared.

The radius is halfway across a circle so our radius would be 4 and we have to square that and we will get a product of 16.

Lastly, we have to multiply 16 by 8 because 8 is the height of the cylinder

16 × 8 = 128

Therefore, the volume of the cylinder would be 128 $\pi$ in.³
