Abrand of cereal had 1.2 mg of iron per serving. then they changed their recipe so they had 1.8 mg of iron per serving. what was the percent increase in iron?

The percent increase in the iron was 50%. 1.2/2 = .6     1.2 + .6 = 1.8

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

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:
