Here is rectangle A. Block A. Rectangle B is ¹/₅ longer than A Block B. Rectangle C is ¹/₃ longer than B Block C. The total leng
Hoochie [10]

Answer:

Rectangle C is 14 cm longer than B

Step-by-step explanation:

Let  x be the length of Rectangle A. Rectangle B is ¹/₅ longer than A Block B,

Therefore the length of rectangle B is:

x+\frac{1}{5}x

Rectangle C is ¹/₃ longer than B, therefore the length of rectangle c is:

x+\frac{1}{5}x+\frac{1}{3}(x+\frac{1}{5}x) =x+ \frac{1}{5}x+\frac{1}{3}x+\frac{1}{15}x=x+\frac{9}{15}x

The total length of all three rectangles is 133 cm.

Length of rectangle A + Length of rectangle B + Length of rectangle C = 133 cm

x+x+\frac{1}{5}x +x+\frac{9}{15}x=133\\x+x+x+\frac{1}{5}x +\frac{9}{15}x=133\\3x+\frac{12}{15}x=133\\ 45x+12x=1995\\57x=1995\\x=35cm

Therefore the length of rectangle A is 35 cm, the length of rectangle B is 35+\frac{1}{5}*35=42\ cm and the length of rectangle C is 35+\frac{9}{15}*35=56\ cm

Rectangle C is ¹/₃ longer than B, which is 14 cm (42\3) longer than B

A grid has lines at 90-degreree angles. There are 12 lines in one direction and 9 lines in the other direction. Lines that are p
denis-greek [22]

Answer:

70

Step-by-step explanation:

Given that:

There are twelve (12) lines in a direction and another nine 9 lines in another direction.

If we draw the above illustration out, we will realize that we will have 11 squares by 8 squares.

i.e these 11 squares are 11 inches apart.

Hence, the length of their grid = 11  inches × 11 inches = 121  inches²

Thus, for 12 in by 12 in tiles; we will have:

= \dfrac {121}{12}

= 10 \dfrac{1}{12}

This implies that there are 10 files with just \dfrac{1}{2} inch gap in length.

Similarly, for 8 squares and 11 inches apart;

The width = 8 inches × 11 inches = 88 inches²

Thus; the 12 in tiles needed = \dfrac{88}{12}

= 7 \dfrac{1}{3}

It signifies that there are 7 tiles with \dfrac{1}{3} inch gap in width.

Thus, the least number of tiles required = 10 × 7 = 70
