If 6x=9y find the value of x:y.​
Ad libitum [116K]

Answer:

A complete angle is one which measures 360∘360∘.

The three angles

6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘

add up to 360∘360∘, as per the question.

6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘

⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘

⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘

⟹2x+3y+z=90∘⟹2x+3y+z=90∘

This is the required relation.

Dilbert’s Incorporated produced 6,000,000 units of software in 2005. At the start of 2006 the pointy-haired boss raised employme
ankoles [38]

Answer:

Productivity fell by about 16.7%.

Step-by-step explanation:

Consider the provided information.

Dilbert’s Incorporated produced 6,000,000 units of software in 2005.

In 2006 production was 7,000,000 units.

In 2005 they was making 6,000,000 units in 10,000 hours.

Per hour output = \frac{6,000,000}{10000} =600

In 2005 per hour output was 600.

In 2006 they are making 7,000,000 units in 14,000 hours

Per hour output = \frac{7,000,000}{14000} =500

In 2005 per hour output is 500.

That means the per hour output decreases. Or we can say that the productivity falls.

The difference between the production:

7,000,000-6,000,000=1,000,000

Therefore, they increase 1,000,000 units.

Decrease in productivity = \frac{1000000}{6000000}\times 100=\frac{100}{6} \approx16.7

Hence, productivity fell by about 16.7%.

Answer:

B 160,000 sq ft

Step-by-step explanation:

2018 is 13 years after 2005.

Put x=13 in the equation and evaluate:

... y = 0.538·13 +9.02 = 6.994 +9.02 = 16.014

This is the number of 10,000 sq ft, so the required area is ...

... 16 times 10,000 sq ft = 160,000 sq ft.
