Answer:
Area = 35 ft^2
Step-by-step explanation:
The shortcut for finding area of a regular polygon is:
Area = 1/2 a•s•n
where a is the apothem, that was given and s is the side length (also given) and n is 5 because a pentagon has 5 sides.
A = 1/2 (3.1)(4.5)5
A = 34.875
The directions say to round to the nearest whole.
A = 35 ft^2
So we're looking for the top half of a fraction. They all appear to equal to 5/10, which is 1/2. Whatever is 1/2 of the denominator (or twice the numerator) is our answer.
?/100; 1/2 of 100 is 50, that answer is 50/100.
3/?; 3 is 1/2 of the denominator, multiply by 2.
3/6.
2/?; multiply by 2. 2/4.
?/10; divide by 2, 5/10.
Hope this helps!
Answer:
1) UUUTU
2) 20 possible outcomes.
Step-by-step explanation:
We have 3 trained rats (T) and 3 untrained cats (U).
1) Which of the following is not a valid outcome?
a) UUUTU is not a valid outcome because we can only have 3 U's at most.
2) How many outcomes are possible for this experiment?
We have to choose 5 rats, at the end we're going to have either 3 trained and 2 untrained (TTTUU) or 3 untrained and 2 trained (TTUUU)
To help with this, we can make a decision tree, which can be observed below.
From the image we can tell that there are 20 possible outcomes for this experiment.
