we know that

To Round a number

a) Decide which is the last digit to keep

b) Leave it the same if the next digit is less than (this is called rounding down)

c) But increase it by   if the next digit is   or more (this is called rounding up)

In this problem we have

We want to keep the digit

The next digit is which is less than , so no change is needed to

therefore

the answer is

Answer:

42 sq. units

Step-by-step explanation:

I don't know if there's an easier way to do this but this is what I came up with. We can break this hexagon into 2 triangles and a rectangle (the 1st triangle using the top 3 points, the 2nd using the bottom 3, and the rectangle using the "middle" ones).

Rectangle area: 7*4 = 28

Triangles (they are equal) : 2*(1/2*7*2) = 14

28+14 = 42

Answer:

42 units squared

Step-by-step explanation:

break it up into smaller shapes. if you split the big shape at y = 2 and at y=-2, you'll get two triangles and one rectangle.

so the area of the rectangle = l x w

= 4 x 7

= 28

the area of the triangle is ( l x w )/2

= (7 x 2)/2

= 7

the other triangle is the same too

so the area of that is also 7.

now add all areas,

7+7+28 = 42

Final answer:

The total number of seats in this movie theater is 4224. This is calculated using the sum of an arithmetic series formula.

Explanation:

The question describes an arithmetic sequence where each row in the theater has four more seats than the previous row. The first row has 20 seats and the last row (44th row) has seats. The total number of seats in this theater is therefore the sum of an arithmetic series formula, which is given by:

Where:

• S is the sum of the sequence
• n is the number of terms
• a is the first term
• l is the last term

So for the number of seats, we have:

So, the total number of seats in the theater is 4224.
