The actual amount of water in a test tube is 680 mL, but when Tim measured it he erred by 3%, too high. What measurement did Tim get? 695.8 mL
695.8 mL ,

713 mL
713 mL ,

683 mL
683 mL ,

700.4 mL

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

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 52 if adding

the answer is 26 if dividing by 2

the answer is 676 if multiplying
