11111nata11111 [884]

Answer:

b. Divide the quantity of output by the number of hours worked.

Step-by-step explanation:

Since the ratio of the number of output to the number of hours worked shows the productivity.

Thus, option (b) is correct.

Productivity is used to converting inputs into useful output. It measures the efficiency of a person, system, machine, factory, etc.

A tile mosaic in the shape of a right triangle is used as the corner for a rectangular pathway. The hypotenuse of the mosaic is

Anit [1.1K]

Answer:

The lengths of the sides are 2.2 ft and 4.5 ft

Step-by-step explanation:

Let

a -----> the length of one side of the mosaic

b ----> the length of the other side of the mosaic

c ----> the hypotenuse of the mosaic

we know that

Applying the Pythagoras Theorem

$c^{2}=a^{2}+b^{2}$ -----> equation A

we have

$a=2b$ -----> equation B

$c=5\ ft$ -----> equation C

substitute equation B and equation C in equation A and solve for b

$5^{2}=(2b)^{2}+b^{2}$

$25=5b^{2}$

$b=\sqrt{5}=2.2\ ft$

Find the value of a

$a=2b$ ------> $a=2\sqrt{5}=4.5\ ft$

therefore

The lengths of the sides are 2.2 ft and 4.5 ft
