This problem should not give you too much difficulty. The area of a triangle is (LxH)/2. The area of a rectangle is LxH. Calculate the area of each triangle and the three rectangles.
When added together, you should get 75.75cm².
I would show the work for you, but just work through it slowly, and you should get the same thing.
Simply the bottom to 2(x-3)
Then the top factors down into (x-3)(x+4)
The (x-3) term cancels out
You are left with ANSWER: (x+4)/2
thank you hope this helps
Answer:
(im not sure what the first question is asking me)
Speed of the current is 2 miles per hour
Step-by-step explanation:
The reason the current is 2 miles per hour is because it when going down stream they were going 14 miles per hour, going upstream they went 10. The difference is 4mph. So if the current pushes you 2mph when going down stream and holds you 2 mph when going up, the constant speed is 12mph then you add and subtract 2 becuase of the two directions youre traveling. hence 10mph and 14mph.
Answer: 10% were missing
Step-by-step explanation:
30 Students = 100% FYI in the problem
1/2 = 50%
50% + 40% = 90%
100% - 90% = 10%
Hope this helps.
P(H,H,H)=P(H,T,H)
This is classical probability, so the probability of an event is the number of "favorable" events over total events.
The total number of events, by the counting principle, is 2^3=8.
The total number of events remains the same for P(H,H,H) and P(H,T,H), as you're still flipping 3 coins with two sides.
For P(H,H,H) the favorable event is (H,H,H) so 1, for P(H,T,H) the favorable event is (H,T,H) also one.
Conclusion:
P(H,H,H)=P(H,T,H)=1/8
