So it seems theres some sort of pattern. When you mutiply 7 by 3 you get 21. When you multply 5 by 7 you get 35. So basically 7 times 7 would be 49. Correct me if im wrong.

The number of seats in each row of an auditorium increases by 2 from one row to the next. if there are 48 seats in the first row

Sveta_85 [38]

Let's see if we can find a pattern:

Row number 1 has $48 = 48 + 2\cdot 0$ seats

Row number 2 has $50 = 48 + 2\cdot 1$ seats

Row number 3 has $52 = 48 + 2\cdot 2$ seats

Row number 4 has $54 = 48 + 2\cdot 3$ seats

Can you see the pattern? After $n$ rows, we have added $2(n-1)$ seats.

So, the 60th row will have

$48 + 2\cdot 59 = 48 + 118 = 166$

Three tables are placed side by side. One table is 6 feet 3 inches wide, another is 3 feet 7 inches wide, and the third is 6 fee

nevsk [136]

Answer:

Total width of tables combined = 16 feet and 4 inches

Step-by-step explanation:

Given:

Width of tables

1) 6 feet 3 inches

2) 3 feet 7 inches

3) 6 feet 6 inches

The tables are combined. We need to find the total width.

Total width of the tables combined = Sum of the widths of the tables

⇒ $6\ ft\ 3\ in+3\ ft\ 7\ in + 6\ ft\ 6\ in$

Adding feet and inches together.

⇒ $(6+3+6)\ ft +(3+7+6)\ in$

⇒ $15\ ft + 16\ in$

[∵ $12\ in = 1\ ft$ , we can split $16\ in = 12\ in + 4\ in$

⇒ $15\ ft + 12\ in+4\ in$

⇒ $15\ ft + 1\ ft+4\ in$

⇒ $16\ ft\ and\ 4\ in$

Total width of tables combined = 16 feet and 4 inches
