Answer:

3, 5, 7

Step-by-step explanation:

As per triangle inequality theorem:

<em>Any side of a triangle must be shorter than the other two sides added together</em>

Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5

Then 1+3< 5 and it is against the above rule, so this is not correct

The next triple is: 3, 5 and 7

Then 3+ 5 > 7 and it is correct

So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle

spin [16.1K]

Answer:

2 5/12

Step-by-step explanation:

you can combine two fractions if they have the same denominator (bottom number) by adding the numerators (top numbers) and keeping the bottom number the same.

1/12+4/12 is the same as 1+4 you just put the sum over 12:

2 1/12+4/12= 2 5/12

it can also be written as 29/12

For the given set, first calculate the number of subsets for the set, then calculate the number of proper subsets. {18, 8, 14, 9

kicyunya [14]

Answer:

Subsets of the given set = 32

Proper subset of the given set = 31

Step-by-step explanation:

Given set is {18, 8, 14, 9, 6} having 5 elements.

We know number of subsets of a set having n elements are represented by

$2^{n}$

where n is the number of elements in the set.

Therefore, subsets of the given set = $2^{5}$

= 32

Since original set itself is a subset of its own, is not a proper subset.

Therefore, proper subset of a set = $2^{n}-1$

= $2^{5}-1$

= 32 - 1

= 31
