The distance traveled by a swinging pendulum decreases after each swing. The first wings distance was 625 mm, The second was 500 mm the third, 400. What was the swing distance be for the seventh swing?

  163.84 mm

Step-by-step explanation:

The swing distances form a geometric sequence with first term 625 and common ratio 500/625 = 0.8. The formula for the general term of such a sequence is ...

  an = a1×r^(n-1)

Then the 7th term of the sequence will be ...

  a7 = 625×0.8^(7-1) ≈ 163.84 . . . mm

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
