Answer:
73.7
Step-by-step explanation:
convert 55% into a decimal .55 then do .55 times 134
297/11 = 27
So we have 27 groups of 11 students. If there are 2 chaperones for every 11 students, then we can do:
27x2=54
There are 54 chaperones on the field trip.
Step-by-step explanation:
If X is a finite Hausdorff space then every two points of X can be separated by open neighborhoods. Say the points of X are . So there are disjoint open neighborhoods and , of and respectively (that's the definition of Hausdorff space). There are also open disjoint neighborhoods and of and respectively, and disjoint open neighborhoods and of and , and so on, all the way to disjoint open neighborhoods , and of and respectively. So has every element of in it, except for . Since is union of open sets, it is open, and so , which is the singleton , is closed. Therefore every singleton is closed.
Now, remember finite union of closed sets is closed, so is closed, and so its complemented, which is is open. Therefore every singleton is also open.
That means any two points of belong to different connected components (since we can express X as the union of the open sets , so that is in a different connected component than , and same could be done with any ), and so each point is in its own connected component. And so the space is totally disconnected.
Answer:
D. Both
Step-by-step explanation:
If you look at one line at a time you'll see that they actually show the exact same thing but the lines are in different spots! Hope this helps!^^
You can first convert the percentage into a decimal. To do this, move the decimal point in 85 spaces to the right. So you know that 85% is equivalent to 0.85.
You can now convert that to a fraction, 85/100. Finally, you can simplify. 100 and 85 are both divisible by 5.
Your final answer is 17/20.
