At a picnic there were 3 times as many adults as children and twice as many women as men. If there was a total of x men, women,
Dennis_Churaev [7]

Answer:

\dfrac{x}{4}

C is correct.

Step-by-step explanation:

At a picnic,

Number of adults is 3 times as number of children.

Number of women is twice as number of men.

Total number of men, women and children at the picnic be x

Let number of children be c

Let number of men be m

Let number of women be w

# Number of women is twice as number of men, w = 2m

# Number of adults is 3 times as number of children, w + m = 3c

      2m + m = 3c     (∴  w=2m )

                c = m

Total number of men, women and children at the picnic be x

∵       c + m + w = x

     m + m + 2m = x

                    4m = x

Number of men, m=\dfrac{x}{4}

Hence, The total number of men will be  \dfrac{x}{4}

Which of the following is correct about environmental policy?a. The national forests are protected from the exploitive ""dual us
Andrew [12]

Answer:

Option C is correct.

Environmental regulation has led to dramatic improvements in air and water quality.

Step-by-step explanation:

- The national forests are protected from the exploitive ""dual use policy.

The dual use policy on any idea, technology, breakthrough etc. means such concept can be used for its intended purpose and for military use.

Natural forests are not excluded from this dual use policy & plenty forest exploiters hide under this policy to literally exploit natural forests.

- The Environmental Protection Agency was elevated to cabinet status in 1998 by President Clinton and the Republican Congress

This is not true as the EPA is still not a Cabinet department, but the Administrator is normally given cabinet rank.

- Environmental regulation has led to dramatic improvements in air and water quality.

Regulations have led plenty industries at the forefront of pollution to sit up and fix up. Strict laws and hefty fines have discouraged various water and air pollution means since those regulations came into place. This is the only correct statement about environmental policy amongst the options.

- Policymakers always give more consideration to environmental protection than to economic development when the two conflict.

This is true sometimes, but 'always'!? No, policymakers do not always give more consideration to environmental protection than to economic development when the two conflict.

Rainbow [258]

Answer:

= 4374.

Step-by-step explanation:

 it is important to understand the pattern hidden in such problem.Let’s give it a try 2, 6, 18, 54 and so on.It can be written as 2, 3*2, 9*2, 27*2 and so on.

This can be further written as2 (1, 3, 9, 27, and so on) as 2 is common in every term.Now if you see the chain 1,3,9, 27 and so….you will see a pattern hidden i.e. 3=1*3 ,9=1*3*3, 27=1*3*3*3 now 27 is the 4th term consist of three 3. So 8th term would consist of seven 3. 8th would be 8th term = 1*3*3*3*3*3*3*3 = 2187 Hence the 8th term for the series 2,6,18,54 would be= 2*2187 = 4374.
