A wire 27 ft long is cut into two pieces. Each piece is bent into the shape of a square. The perimeter of the larger square is twice the perimeter of the smaller square. Find the perimeter of the larger square.

Perimeter of the smaller square = 9 ft

Perimeter of the larger square = 18 ft

Step-by-step explanation:

Let

Perimeter of the smaller square = x

The perimeter of the larger square is twice the perimeter of the smaller square.

Perimeter of the larger square = 2x

Total Length of the piece of wire = 27 ft

Total = smaller + larger

27 = x + 2x

27 = 3x

x = 27/3

x = 9 ft

Perimeter of the smaller square = x

= 9 ft

Perimeter of the larger square = 2x

= 2(9)

= 18 ft

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
