Hey!

Hope this helps....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

For Question 2: 6+3+n=12

This is because we know that there is a combined total of 12, so it has to equal 12 (which cancels out C), we also know that the question is not saying anything that implys that we are multiply anything thing (which cancels out B, and D), so we are only left with A.) 6+3+n=12


For Question 4: 2 (Fraction 2 over 3)

This is because when we substitute all those choices in for y, we get...

2/(3*(3/8)) ~ 1.77778

2/(3*(5/12)) = 1.6

2/(3*(11/12)) ~ 0.727273

2/(3*(8/3)) = 0.25

^^^^ I got 8/3 from A (b/c) > ((A*c)+b)/c

(And we know 1/4 = 0.25)

A middle school mathematics teacher except a teaching position that pays 40,000 per year, each year the expected raise is $2000.
Grace [21]

9514 1404 393

Answer:

  $2,070,000

Step-by-step explanation:

The series of salaries has a first term of $40,000 and a common difference of $2,000. The sum of them is given by the formula ...

  Sn = (2a1 +d(n -1))(n/2)

where a1 is the first term of the series, d is the common difference, and n is the number of terms.

In this problem, we have ...

  a1 = 40,000; d = 2,000; n = 30

so the sum is ...

  S30 = (2(40,000) +2,000(30 -1))(30/2) = (80,000 +58,000)(15)

  S30 = 2,070,000

The teacher will earn $2,070,000 over 30 years on this salary schedule.

Find the area of the square in inches2 and enter your answer below. Do not include units in your answer.
saveliy_v [14]

Answer:

11.56

Step-by-step explanation:

The area formula is just Length * Height. Since this shape is a square, both the length and height are equivalent to the same thing, 3.4. So, all we have to do is multiply 3.4 * 3.4, or we can do 3.4^2.
