Answer:
A
Step-by-step explanation:
- f=1/2(a+b)×h
- 1/2(1.6+4)×2
- 2.8×2
- 5.6 since to round off 5.6 to the nearest tenth consider the hundredths' value of 5.6 which is 0. therefore the tenths value of 5.6 remains 5.6
Answer:
Pr(opposite face is tail) = 1/4. = Option (a)
Step-by-step explanation:
From the illustration,
=> 1st coin has head both side
=> 2nd coin has tail both side
=> 3rd coin has head and tail.
If we toss a coin at random and head comes up; it implies that it can never have been the 2nd coin.
Consequently, we are left with only two coins (the 1st and the 3rd coin). Now, total number of coin that remain in the sample = 2.
Meanwhile,
=> the probability of tail from the 1st coin is ZERO
=> the probability of tail from the 3rd coin is 1/2.
Therefore, the probability of opposite face is tail is:
Pr(opposite face is tail) = (0+ 1/2)/2 = 1/4
This is really easy if you think and look at the picture.
There were 15 dvds. 1/5 were documentaries.
All you have to do is figure out what 1/5 of 15 is. Yes?
So to find out what 1/5 of 15 is, you divide 15 by 5, and that's your answer.
The answer is 3.
85/11.9 whatever that works out to
<u><em>Answer:</em></u>
There would have been, 20 bottles collected, 25 pieces of paper collected, and 10 cardboard boxes. Theses three therefore show 55/100, of the total amount collected.
<u><em>Step-by-step explanation:</em></u>
So, to get this answer ^^, I had to find out how much each one of the materials was actually collected. So, for the bottles, I thought of how many 5's went into 100, which is 20, and then did 20 x by 1 (the fractions numerator), which gave me 20, therefore there was 20 bottles. Then, I did the same with the paper and the cardboard boxes. The paper was: 100 divided by 4 = 25, 25 x 1 is 25, and then the cardboard boxes was: 100 divided by 10 which is 10, 10 x 1 = 10.
Hope this helps! Xo
