Answer:
144
Step-by-step explanation:
<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u><u> </u>
- Least Common denominator .
<u>Solution</u><u> </u><u>:</u><u>-</u><u> </u>
We have ,
> 1/8 , 2/9 , 3/12 .
The denominator of the fractions are ,
> 8 , 9 , 12
The LCM of 8,9,12 will be ,
2 |<u> </u><u>8</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>1</u><u>2</u><u> </u>
2 <u>| 4 , 9 , 6</u>
2 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>9</u><u> </u><u>,</u><u> </u><u>3 </u>
3 |<u> </u><u>2</u><u> </u><u>,</u><u> </u><u>3 </u><u>,</u><u> </u><u>1</u><u> </u>
Therefore , LCM will be ,
> 2⁴ × 3² = 16 × 9 = 144
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
