Given 45-45-90 triangle with hypotenuse of 3cm solve for the other sides.

Answers

Answer:

[tex]\sqrt{\frac{9}{2} }[/tex]

Step-by-step explanation:

Given dimensions:

   The right angle system is a 45 - 45 - 90

    Hypotenuse  = 3cm

Unknown:

Adjacent and opposite sides = ?

Solution:

In this triangle, the adjacent and opposite sides are equal to one another. So,

 Let adjacent  = y

        opposite  = y

For right angle triangles as this, using the Pythagoras theorem,

           hypotenuse²  = adjacent² + opposite²

 Insert the parameters and solve;

                    3² = y² + y²

                    2y²  = 9

                       y² = [tex]\frac{9}{2}[/tex]

                       y = [tex]\sqrt{\frac{9}{2} }[/tex]

Suzanne Attired makes fashionable garments. During a particular week employees worked 360 hours to produce a batch of 132 garments, of which 52 were seconds (meaning they were flawed). Seconds are sold for $90 each at Attired's Factory Outlet Store. The remaining 80 garments are sold for $200 each. What is the labor productivity ratio of this manufacturing process

Answers

Answer:

$57.44 per hour

Step-by-step explanation:

Given that :

Hours worked = 360 hours

Production = 132 batches of garment

Of the 152:

52 were flawed (sold at $90 each)

80 were sold at $200 each

Labor productivity ratio: (output value / input value (hours worked))

Output value = [(52*$90) + (80*$200)]

Output value = $20,680

Labor productivity ratio = $20,680 / 360 hours

Labor productivity ratio = $57.44 per hour

Over the course of a week, an airline has 42 flights between New York and Los Angeles. Of these flights, 28 are considered

to be "on-time."

If you chose a particular flight at random, what is the probability that it would not be on-time? Express your answer as a

fraction.

Provide your answer below:

Answers

Answer:

The probability that a particularly randomly chosen flight will not be on time is 1/3

Step-by-step explanation:

The number of flights available between New York and Los Angelis = 42 flights

The number of flights that are considered to be on time = 28 flights

The probability that a particularly randomly chosen flight will not be on time = 1 - The probability that the flight will be on time

The probability that the flight will be on time = (The number of flights considered to be on time)/(The total number of flights available)

The probability that the flight will be on time = 28/42 = 2/3

∴ The probability that a particularly randomly chosen flight will not be on time = 1 - 2/3 = 1/3

The probability that a particularly randomly chosen flight will not be on time = 1/3.
