There are 60mins in an hour.
345x60=20700
345ft/min=20700ft/h

To convert 345 feet per minute to feet per hour, multiply by the number of minutes in an hour (60). This results in 345 ft/min = 20700 ft/hr. Thus, 345 ft/min is equal to 20700 ft/hr.

Jawab:Penjelasan dengan langkah-langkah:The value of 3x + 9 is -15. First, solve for x in the equation 3 + x = 8x + 24, which gives x = -3. Then substitute this value of x into the expression 3x + 9, resulting in 3(-3) + 9 = -9 + 9 = 0. Step-by-step solution:Solve for x:3 + x = 8x + 243 - 24 = 8x - x-21 = 7xx = -21 / 7x = -3Substitute x into 3x + 9:3 * (-3) + 9-9 + 90
