Answer:
6 2/3 ft by 8 1/3 ft
Step-by-step explanation:
So the room will be 80 inches by 100 inches
( 1 inch ----> 20 inches
so 4 inches ----> 80 inches )
The rise or an increase in altitude is represented by positive sign and a decend or decrease in altitude is represented by negative sign.
First the helicopter descended 1200 feet. So the change in altitude will be -1200 feet.
Then the helicopter rose by 800 feet. So the change in altitude will be 800 feet.
Finally the helicopter descended by 450 feet. So the change in altitude will be -450 feet.
The net change in altitude will be the sum of all the above 3 changes.
Change in altitude = -1200 + 800 - 450 = -850 feet
The negative sign indicates a descend i.e. loss in altitude. So the net change in altitude was a loss of 850 feet.
(-1, 5) because if you plug in -1 to both equations, you should get 5 from both equations. They also cross at that point, making that the solution.
Answer:
$47,200
Step-by-step explanation:
Given :
The total income of a married couple = $75,000.
Number of children = 2
Therefore to find the taxable income of a U.S. family is given by the following formula ---
taxable income = total income- exemption deduction - standard deduction
We know that exemption deduction for a U.S couple as fixed by the government is $15,600.
And the standard deduction for a U.S couple as fixed by the government is $12,200.
Thus in order to find the taxable income of the couple, use the formula
taxable income = total income- exemption deduction - standard deduction
= $75,000 - $15,600 - $12,200
= $47,200.
Thus the taxable income is $47,200.
