Answer:
The length of the sides are 8 , 32 , 36
Step-by-step explanation:
Ratio of sides = 2 : 8 : 9
The sides are 2x , 8x , 9x
Perimeter of triangle = 76 inches
2x+ 8x + 9x = 76
19x = 76
x = 76/19
x = 4
2x = 2*4 = 8
8x = 8 * 4 = 32
9x = 9 * 4 = 36
The expressions are irrational 1/3 + √216 and √64+ √353 and the expressions √100 × √100, 13.5 + √81, √9 + √729, and 1/5 + 2.5 are rational number.
<h3>What is a rational number?</h3>
If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.
1. √100 × √100
→ √100 × √100
→ 10 × 10 = 100
This is a rational number.
2. 13.5 + √81
→ 13.5 + √81
→ 13.5 + 9 = 22.5
This is a rational number.
3. √9 + √729
→ √9 + √729
→ 3 + 27 = 30
This is a rational number.
4. √64+ √353
→ √64 + √353
→ 8 + √353
This is an irrational number.
5. 1/3 + √216
→ 1/3 + √216
→ 1/3 + √216
This is an irrational number.
6. 1/5 + 2.5
→ 1/5 + 2.5
→ 0.2 + 2.5 = 2.7
This is a rational number.

Answer:
257142857143 / 100000000000.
Step-by-step explanation:
2.57142857143
= 2 + 57142857143 / 100,000,000,000
= 200,000,000,000 + 57142857143 / 100,000,000,000
= 257142857143 / 100000000000.
Answer:
