Answer:
35 different selections of soundtracks are possible
Step-by-step explanation:
Total number of soundtracks available at the store = 7
Enny decides to purchase 3 movie soundtracks.
So, in this problem we have to find in how many ways can Enny chose 3 soundtracks out of 7. The order in which the soundtracks are chosen does not matter e.g soundtracks A,B and C are the same as soundtracks B,C and A.
In an arrangement when the order does not matter, we use combinations to find the total possible number of arrangements or selections.
So, for this problem choosing 3 soundtracks out of 7 means forming combinations from 7 objects taken 3 at a time. This can be represented mathematically as:
The general formula for combinations is:
Using the values, we get:
This means, Enny can make 35 different selections of soundtracks.
Answer: Greater than 5 and less than 6
Step-by-step explanation:
5.5 x 5.5 = 30.25
So the closest answer is greater than and less than 6.
5.47 x 5.47 = 29.9
31/177 is the answer I’m pretty sure

Answer:
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Little wooden cubes edge length = 1/2 inch
Larger cube edge length = 4 inches.
2. How many little cubes does Clare need to build the larger cube?
We can calculate the number this way:
Number of little cubes for building a larger cube = 4/0.5 (1/2 = 0.5)
Number of little cubes for building a larger cube = 8
<u>Clare will need 8 little cubes of 1/2 edge length to build a larger cube that has 4 inches of edge length.</u>
