Answer:
8,643
Step-by-step explanation:
The thousands digit is 8 so we know it is 8,000 The hundreds digit is 2 less than 8, so it's 6, giving us 8,600. The units digit is half the hundreds digit, so it is half of 6, or 3, now we have 8,603. Lastly, the tens digit is one greater than the units digit, so it is 4, leaving you with 8,643.

Answer:
Interior-140° Exterior-40°
Step-by-step explanation:
The sum of the interior angles of a polygon are given by 180(n-2) where n is the number of sides.
Therefore, the sum of all interior angles in a nonagon is 180(9-2) or 180×7. This equals to 1260°.
To get the individual interior angle, you use 
, with n defined above and s being the sum of interior angles.
Therefore, each angle is 
°, which can be solved to 140°.
The value of an individual exterior angle is given by 180-i, with i being the individual interior angle (this is because the 2 angles form a straight line).
In this case, 180-140=40°.
Each interior angle of a nonagon is 140°, and each exterior angle is 40°.

Answer:
D. Alex
Step-by-step explanation:
John had 2⁄3 of his homework complete,
Sarah had 5⁄10,
Alex 7⁄8,
and Michelle 1⁄2.
We have to find who completed the most of the homework assignment.
2/3=0.67
5/10=0.5
7/8=0.875
1/2=0.5
Clearly, Alex completed most of the homework assignment.
Hence, the correct option is:
