ZW = WM and YP = PT
This means line PW is the middle of the shape.
PW = 29
YZ = 23
29-23 = 6
There is a difference of 6 btween the top line and the middle line, so there needs to be a difference of 6 from ther middle line to the bottom line.
The bottom line needs to equal: 29 +6 = 35
11x +2 = 35
Subtract 2 from each side:
11x = 33
Divide both sides by 11:
x = 33/11
x = 3
The answer is B.
Answer:
See below in bold.
Step-by-step explanation:
The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).
So the area of one piece = 1/2 * 9 * 40 cm^2.
The total amount of cloth required for one umbrella = 10 * 1/2 * 9 * 40
= 1800 cm^2.
The total cost = 1800 * 0.25 = Rs 450.
Cloning vectors are the DNA molecules that can carry a foreign DNA segment into the the host cell.The vectors used in recombinant DNA technology can be plasmids, cosmids, bacteriophages etc.
Plasmids: Self replicating, circular, extra chromosomal DNA present in bacteria. Plasmids have only one or two copies per cell.
Bacteriophages: Virus infecting bacteria. Bacteriophages have high number per cell, so their copy number is also high in genome.
Cosmids: Hybrid vectors derived from plasmids which contain cos site of lambda phage.
Feature required to facilitate cloning into vector: Origin of replication, Selectable marker, unique restriction sites.
The purpose of cloning vector is often to make numerous copies of the inserted gene.
Expression Vectors: The cloning vector containing suitable expression signals to have maximum gene expression, is called expression vector.
The following expression signals are introduced into gene cloned vectors to get maximum expression:
Insertion of a strong promoter.
Insertion of a strong termination codon.
Adjustment of distance between promoter and cloned gene.
Insertion of transcription termination sequence.
Insertion of a strong translation initiation sequence.
Answer: See explanation
Step-by-step explanation:
Number of tickets Elian won = e
Number of tickets Alberto won = A = e - 10
Therefore, Elian + Alberto ticket = 100
e + (e - 10) = 100
2e - 10 = 100
2e = 100 + 10
2e = 110.
e = 110/2
e = 55
Elina has 55 tickets
Alberto has 55-10 = 45 tickets
