Answers
Answer:
r = r
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80 = 4r + 80
- 80 - 80
4r = 4r
4 4
r = r
Answer:

Step-by-step explanation:
29x - 3 + 15x + 7 = 18 because these two angles are supplementary
29x + 15x + 7 - 3 = 18044x = 176 divide both sides by 44x = 413y - 17 = 29x - 3 because these two angles are alternate
since we know the value of x

On line a where it intersects line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 2, 4, 3. On line b where it intersects line c, 4 angles are created.

Answers
Answer:
The correct option is;
Corresponding angles theorem
Step-by-step explanation:
Type of lines of lines a and b = Horizontal and parallel lines
The transversal to a and b = Line c
The angles between a and c labelled clockwise from the upper left quarter segment = 1, 2, 4 and 3
The angles between b and c labelled clockwise from the upper left segment = 5, 6, 8 and 7
Therefore, we have;
Statement [tex]{}[/tex] Reason
1. a║b, c is a transversal [tex]{}[/tex] Given
2. ∠6 ≅ ∠2 [tex]{}[/tex] Corresponding angles theorem
3. m∠6 = m∠2 [tex]{}[/tex] Definition of congruent
4. ∠6 is supp. to ∠8 [tex]{}[/tex] Definition of linear pair
5. ∠2 is supp. to ∠8 [tex]{}[/tex] Congruent supplement theorem
Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.

20 ft
Main
hallway
d. the closet
Closet
Bathroom
e. What is the area of the main hallway? Explain how
you could find this area using the area of each room
20 ft
Answers
Answer:
Step-by-step explanation:
a). Perimeter of the kitchen = total length of all sides
= 4 + 2 + 2 + 6 + 6 + 12 + 10 (Since side of one smallest square = 2 feet)
= 42 ft
Area of the kitchen = Area of the composite figure
= 4² + 2² + (6 × 12)
= 16 + 4 + 72
= 92 square feet
b). Perimeter of bedroom = 2(length + width)
= 2(12 + 8)
= 40 feet
Area of the bedroom = Length × Width
= 12 × 8
= 96 square feet
c). Perimeter of the bathroom = 2(9 + 4) = 26 feet
Area of the bathroom = 9 × 4 = 36 square feet
d). Perimeter of the closet = 2(6 + 8) = 28 feet
Area of the closet = 6 × 8 = 48 square feet
e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)
Area of the floor plan = 20 × 20 = 400 square feet
Area of the hallway = 400 - (92 + 96 + 36 + 48)
= 400 - 272
= 128 square feet

What is the combined weight of the bee and the pollen? Express your answer in scientific notation.
Answers
Answer:
0.18 g
Step-by-step explanation:
Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]
Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]
The above values can be written in the following ways
[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]
[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]
Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]
The combined weight of the honeybee and the pollen is 0.18 g.
