On a board measuring 1x100, each square is numbered from
max2010maxim [7]

Answer:

97

Step-by-step explanation:

Given the following conditions :

board measuring 1x100, each square is numbered from 1 to 100

Three colors are used to paint the squares from left to right in the sequence :

one blue, two reds and three green squares in a repeated pattern.

What is the highest numbered square that is painted blue?

The sequence of painting is repeated after :

(1 + 2 + 3) = 6 successive squares

Since the number of squares = 100

Maximum complete repetition possible :

100 / 6 = 16 remainder 4

Hence 16 * 6 = 96 (the highest complete sequence terminates on the square numbered 96)

On the 97th square, another sequence begins which is a blue and the 100th square is painted the first of the 3 green colors.

Hence, the highest numbered square that is painted blue is 97

The equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y.
Katarina [22]
Start the graph at the <em>y</em>-intercept.  At 0 hours, he will make $0, so (0, 0) is the <em>y</em>-intercept.  From this point, he makes $8.10 an hour; go up 8.1 for every 1 hour you go over on the graph.  The graph is attached.

The table shows the relationship between a, the area of a rectangle, and h, its height, when the base remains constant.
olganol [36]

Answer:

a = 4h.

Step-by-step explanation:

Area (a) = base (b) * height (h).

When h = 2, a = 8:

a =  bh

6 = 2b

b = 4

The result 4 is the same for  h = 5, 7 and 12.

So the required equation is

a = 4h.
