Answer
Find out the what is the total length of the wood .
To prove
As given in the question the length of the five pieces of wood are
73 cm+ 1.6m + 2.87m + 325cm + 4.04m
As 1m = 100cm
1 cm = 0.01m
73 cm is converted into meter = 73 × 0.01
= 0.73 m
325cm is converted into meter = 325 × 0.01 m
= 3.25 m
Total length of the length of wood = 0.73m + 1.6m + 2.87m + 3.25m + 4.04m
simply adding the above terms
Total length of the length of wood = 12.49 m
Therefore the total length of the wood is 12 .49 m .
The 1 and 1 represent the 2 friends.
Answer:
<u>Given:</u>
- DC ║ AB
- CM = MB as M is midpoint of BC
i) <u>Since DN and BC are transversals, we have:</u>
- ∠DCM ≅ ∠NBM and
- ∠CDM ≅ ∠BNM as alternate interior angles
<u>As two angles and one side is congruent, the triangles are also congruent:</u>
- ΔDCM ≅ ΔNBM (according to AAC postulate)
So their areas are same.
ii)
<u>The quadrilateral has area of:</u>
- A(ADCB) = A(ADMB) + A(DCM)
<u>And the triangle has area of:</u>
- A(ADN) = A(ADMB) + A(NBM)
Since the areas of triangles DCM and NBM are same, the quadrilateral ADCB has same area as triangle ADN.
Answer:
-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.
Step-by-step explanation:
It should have been, write problem
-4(x - 3) = 20
Use distributive property.
-4x + 12 = 20
subtract 12 from each side
-4x =8
divide each side by -4
x = -2
