Select all the sets of three side lengths that will make a triangle.

Answer:

B, C

Step-by-step explanation:

to make a triangle the sum of lengths of any and every pair of sides must be longer than the third side. otherwise the end points cannot connect.

A

3+4<8 so, it cannot be a triangle.

B

7+6>12 true

7+12>6 true

6+12>7 true

C

5+11>13 true

5+13>11 true

13+11>5 true

D

4+6<12 so, it cannot be a triangle.

E

special case

4+6 = 10

but 4+6 is not longer than 10, so, all 3 lines would "fold" into one flat line. that does not count as triangle either, although I, personally, would consider it an "extreme triangle". but the general definition does not agree with me and requires the "longer than" condition.

Irina18 [472]

Step-by-step explanation:

We are given that,

Total number of bottles = 5

As, each bottle is divided into 4 portions.

The amount of water per person = \frac{1}{4}

Further, Sarah took 1 portion from each bottle and there are 5 bottles.

So, the amount of water Sarah have = \frac{1}{4}\times 5 = \frac{5}{4}

Hence, Sarah have \frac{5}{4} bottle of water.

AURORKA [14]
10 <0.25 (x + 1) <11
 
We must solve two inequalities in this case.
 Inequality 1:
 
10 <0.25 (x + 1)
 10 / 0.25 <x + 1
 40 <x + 1
 40-1 <x
 39 <x
 Inequality 2:
 
0.25 (x + 1) <11
 (x + 1) <11 / 0.25
 (x + 1) <44
 x <44-1
 x <43
 The final result is:
 39 <x <43
 Answer:
 
39 <x <43
