Answer:First we need to turn 1 5/7 into an improper fraction 7x1+5 = 12/7
12 / 7 x 5 / 6 = 60/42 ....reduced.....10/7
10/7 as a mixed number is 1 3/7
Step-by-step explanation:
Answer:
28.26 in
Step-by-step explanation:
Radius = (1/2) diameter
Radius = (1/2)(9)
Radius = 4.5 in
Circumference = 2πr
Circumference = 2(3.14)(4.5)
Circumference = 28.26 in
Answer:
b=9
Step-by-step explanation:
18/24=3/4
3/4=b/12
cross product
4*b=3*12
4b=36
b=36/4
b=9
The answer is 12:1
note: this is often read as "12 to 1"
==============================================
Explanation
We have exactly four card that are labeled "3" and 52 cards total. So there are 52-4 = 48 cards that are not labeled "3".
From here you write the ratio 48:4 to indicate the odds against drawing a 3. There are 48 ways to lose, 4 ways to win. You list the number of ways to lose first when it comes to "odds against" type of problems.
Next step is to reduce the ratio 48:4 to get 12:1, note how I divided both parts by the GCF 4
48/4 = 12
4/4 = 1
So thats how 48:4 reduces to 12:1
If you focus on one suit, say the spades, then we have 12 cards that arent a 3 of spades while exactly one card is a 3 of spades. This is one way to see why 12:1 is the answer. If you were saying this out loud to a friend, then you might say something like "the odds against drawing a three are 12 to 1".
