How this animation demonstrates that the sum of the angles in this triangle is 180 degrees.

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:

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

d is ur answer hopes this i dont really know how to explain it to u.
