Suppose CDEF represents the wing you built as part of the reconstruction of a vintage airplane model overline CF is to be attached to the plane with overline CD closest to the propeller. You friend will build the second wing, QRST, congruent to CDEF, but needs instructions for how to place their wing exactly like you did. What are your instructions?

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

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:

the eight graders whould be the answer
