You got 3 problems on a 25 question yest what was the percent of the questions you got right?

If you got 3 questions wrong, then you got 25-3 = 22 right. So that would be 22/25 = 0.88 = 88% questions correct

If you got 3 questions right out of 25, then 3/25 = 0.12 = 12% is the score you get. Note how 88% + 12% = 100%

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 answer is 1030 it's very simple math.
