Gotta convert this to make it save some time.
1 over 18 = 1/18
1 over 3 = 1/3
If 1/18 of a lawn is wattered in 20 mins, (Simply coverting 1/3 hr to mins by doing 60/3) 20 * 18 = 360 Mins = 6 Hours
It takes 6 hours to water the entire lawn
Answer: Choice D) Opposite sides of a parallelogram are congruent
Likely a typo has been made because A, B, C, and D aren't shown. I think your teacher meant to say PQ = RS and QR = PS
A parallelogram has properties that the opposite sides are parallel, and it can be proven that the opposite sides are congruent as well.
Answer:
they are similar
Step-by-step explanation:
this is because of the degree of the angles and the measurements between the edges. The only reason it may not look the same is because it has been rotated and downsized.
The answer ex + 2<span> - 1</span>
Since order does not matter, ie Joe, Jim, and Dave is the same as say Jim, Dave, and Joe. You would use the "n choose k" formula for unique combinations...
n!/(k!(n-k)!), where n=number of possible selections and k=selections made...
12!/(6!(12-6)!)
12!/(6!6!)
924
So there are 924 possible different committees of six people from a pool of twelve people.
