I=prt
1200=960*x*5
1200=4800x
divide both sides by 4800
x=0.25
Answer:
h = 13 m
Step-by-step explanation:
The triangles are similar, so the ratios of corresponding sides are equal, that is
= 
= 
( cross- multiply )
3h = 39 ( divide noth sides by 3 )
h = 13
Answer:
x=5/2
Step-by-step explanation:
4x-2=2x+3
1) Add 2 to both sides:
4x=2x+5
2) Subtract 2x from both sides:
2x=5
3) Divide both sides by 2:
x=5/2

Answer:
<h2>
3/5</h2>
Step-by-step explanation:
If Jennifer has 25 books on her bookshelf and she has 10 fiction books, the number of non-fiction books she has will be 25-10 = 15 non- fiction books.
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome of event/total outcome.
Since we want the expression that represents the probability that the book she selects will be a non-fiction book, our expected outcome will be 15(the total non fiction she selected)
The total outcome will be the total number of books i.e 25.
Probability that she elects non fiction book = 15/25
= 3/5
