The altitude of an airplane is decreasing at a rate of 44 feet
per second. What is the change in altitude of the airplane
over a period of 25 seconds?

-1,100 feet

Step-by-step explanation: If it declines 44 feet per second for 25 seconds, multiply 44*25. This gets you 1,100 feet, and since the airplane is declining, the altitude change is negative.

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
