Carolina goes to a paintball field that charges an entrance fee of \$18 and $0.08, per ball. The field has a promotion that says, "Get $10 off if you spend $75 or more!" Carolina wonders how many paintballs she needs to buy along with the entrance fee to get the promotion. Let B represent the number of paintballs that Carolina buys.
1) Which inequality describes this scenario?

18+0.08B>75

Step-by-step explanation: 713 paintballs

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:
