What is the value of the expression 1/2 (m-4) n A. 1/2 B. 1 C. 2 D. 7/2 plz give explination

1

Step-by-step explanation:

1/2 (m-4) n

Let m = 12 and n = 1/4

1/2 (12-4) 1/4

PEMDAS says parentheses first

1/2 *  8*1/4

Then multiply from left to right

4 * 1/4

1

B. 1

Step-by-step explanation:

We are given the expression

1/2(m-4) *n

We also know that m=12 and n=1/4. Therefore, we can substitute 12 in for m and 1/4 in for n.

1/2(12-4) *1/4

Solve according to PEMDAS.

First solve inside the parentheses. Subtract 4 from 12.

1/2(8) *1/4

Multiply from left to right.

First,, multiply 1/2 and 8. Multiplying by 1/2 is the same as dividing by 2.

1/2*8=4

8/2=4

4*1/4

Next, multiply 4 and 1/4.

4/1* 1/4

= 4/4

=1

Therefore, the correct answer is B. 1

if you mean

then it's c. 8, -7/3

but if you mean

then it is

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
