Answer:

12 minutes

Option D

Step-by-step explanation:

Given that circuar gears P and Q start rotating at the same time at constant speeds.

Gear P makes 10 revolutions per minute and Gear Q makes 40 revolutions per minute.

Both gears start at the same time.

No of rotations per minute are 10 and 40

Difference is 30 in one minute

For 6 difference we must have exactly 1/5 minutes

which equals 12 seconds.

In 1/5 minutes or 12 seconds  gear P would have completed 2 revolutions while Gear Q would have completed 8 revolutions thus making difference as 6.

Answer:

The center is (20, 0.05)   radius = 9

Step-by-step explanation:

The center is (20, 0.05)   radius = 9

from the general form of the equation:

(x - h)^2 + (y - k)^2 = r^2

we see that  r^2 = 81

so r = 9

Find each missing lengths to the nearest tenth PLEASE HELP
alisha [4.7K]

Answer:

For #1, 8.9.

Step-by-step explanation:

I can attempt to answer it, but I can't promise anything.

Alright, so, the equation for this should be A²+B²=C²

C is usually the longer side, which for you is the side that is missing.

Let's try the first one. If what I see is right, the 2 sides are 4 and 8. A is 8 and B is 4.

That means that the equation would be 8²+4²=C²

That would be 64+16=80

The equation is now 80= c²

The opposite of "to the power of 2" is a square root. So, now you're going to find the square root of 80, which is 8.9 to the nearest tenth.

So, for the first question, the answer should be 8.9

I hope this helps you solve the rest.
