Answer: B) 30</h3>
Any amount of rotation will not change the angle between the two spokes. This is because each piece of the wheel moves in unison as the rotation is applied. Nothing changes about the wheel. Imagine instead of rotating the wheel, we instead rotated the camera that is capturing the wheel (or the person looking at the wheel rotates their head). This is a good way to see how the wheel itself isn't changing at all, but instead rather just the look of it is changing.
Answer:
A
Step-by-step explanation:
5a+4=9a+3-4a
5a-9a+4a=3-4
a=-1
Step-by-step explanation:
Day 1: 1200g / 2¹ = 600g
Day 2: 1200g / 2² = 300g
Day 3: 1200g / 2³ = 150g
The pattern is the amount of radioactive substance on day n is 1200 / (2^n).
Therefore, we have to find n where 2^n > 1200.
The first such n is 11 (2¹¹ = 2048).
Hence, there will be less than 1 gram on day 11.
Answer:
True: If you add 6 to a, this will be greater than b.
Step-by-step explanation:
If the ordered pair (a,b) satisfies the inequality y < x + 6, then the coordinates of this point satisfy the inequality. Substitute into the inequality x = a and y =b:

Check all options:
A. Subtract 6 from b:

So, if you subtract 6 from b it will be less than a but never equal to a, so this option is false.
B.

So, a is greater than b - 6, not b. This option is false.
C. If you add 6 to a, then

This option is true.
D. a+6 is greater than b, so it cannot be less than b. This option is false.
