Answer:
D 9/DF = 18/16
Step-by-step explanation:
Corresponding sides are proportional. The proportions based on a given similarity statement can be written 4 ways.
For these isosceles triangles, the similarity statement could be written either of two ways:
ΔDEF ~ ΔABC or ΔDEF ~ ΔCBA
Corresponding sides will depend on the similarity statement you use. Using the first one, they are ...
DF and AC (short sides)
DE and AB (long sides)
EF and BC (long sides)
For each (short side, long side) pair, we can write the proportion 4 ways:
- DF/DE = AC/AB ⇒ DF/9 = 16/18
- DF/AC = DE/AB ⇒ DF/16 = 9/18
- DE/DF = AB/AC ⇒ 9/DF = 18/16 . . . . . matches choice D
- AC/DF = AB/DE ⇒ 16/DF = 18/9
Using the other pair of long sides, or using the other similarity statement, the numerical proportions are the same as the ones listed above.
Answer:
I believe thw correct answer is B
Answer:
See explaination for the details of the answer
Step-by-step explanation:
Defect per opportunity DPO = defects/ no. of opportunities = 2/25 = 0.08
Defect per million opportunities
DPMO = DPO * 1 million
DPMO = 0.08 * 1 million = 80,000
six sigma = 2.9, take the dpmo at higher level if not exact 80800 for 2.9
Answer:
20
Step-by-step explanation:
You can only get x
The lines are parallel.
The two interior angles add up to 180 degrees. (Property of a transversal cutting to parallel lines)
3x + 6x = 180 Combine the left side
9x = 180 Divide by 9
9x/9=180/9 Do the division
x = 20
