3 0

Answer:

x must equal 0 or - 10

and y must equal 1 or 6

so its 3 x 0 = 0 plus 6 x 1 = 6

or 3 x -10 = -30 plus 6 x 6 = 36 so -30 plus 36 is 6

A 2 by 3 rectangle contains 8 squares. A 3 by 4 rectangle contains 20 squares. A 4 by 6 rectangle contains 50 squares. What size
scZoUnD [109]

Answer:

The rectangles that have exactly 100 squares are 1 by 100  4 by 11 and 5 by 8

Step-by-step explanation:

The given parameters are;

A 2 by 3 rectangle contains 8 squares

A 3 by 4 rectangle contains 20 squares

A 4 by 6 rectangle contains 50 squares  

We note that the number of squares varies proportionately to the increase in the dimension of the rectangle, that is we have;

2 by  3 rectangle contains 8 squares

3 by 4 rectangle contains 20 squares increase by 12 = 3 × 4

4 by 5 rectangle contains 40 squares increase by 20 = 4 × 5

The number of squares formed can therefore be arranged in a matrix as follows(please see attached matrix);

Column,     1,       2,     3,      4,       5,     6,        7,       8,         9,           10,         11

Row

1

2

3

4

5

6

7

8

9

10

11

It will be observed that after reaching a point where the row and column are equal, (x, x) the rate of increase in the number of squares become constant and equal to x × ((x - 1) × 0.5) + 1) = x × (x + 1)/2

From the matrix, the rectangles that have exactly 100 squares are 1 by 100  4 by 11 and 5 by 8 and there are no more as presented in the attached matrix, the number of squares formed keeps increasing for each column and row added.

What is 67% of 296 ? Show your work
seraphim [82]
First, you would get the decimal form of 67% by moving the decimal (At the end of most whole numbers.) over two, giving you .67.
Next, multiply 296 by this new decimal- .67*296=198.32.
There you go! : )

Given that,

Length of 4 pieces of wood are 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

To find,

The length of the strip of wood.

Solution,

Mark glues together four pieces of wood to make one long strip.

Long strip = The sum of 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

L = 16.75 + 9 + 24.25 + 12.5

= 62.5 inches

Hence, the strip of wood is 62.5 inches long.
