It costs $12 for admission to the Fair, plus $0.50 for each ticket to play games. If you have a total of $30 to spend, what is the greatest amount of tickets you can buy?

36 tickets

Step-by-step explanation:

The expression is given as:

$12 + $0.50× x = $30

12 + 0.50x = 30

0.50x = 30 - 12

0.50x = 18

x = 18/0.50

x = 36 tickets

Therefore, the greatest amount of tickets you can buy is 36 tickets

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:
