Let:
Lala be l
Polina be P
Goffy be G
the respective ratio is 6:5:3
Given that Polina's loudness is 420 decibels then the total loudness will be calculated as follows:
Total ratio=6+5+3=14
hence total loudness will be:
14/5×420
=1,176 decibels
The distance between the ships is 26.65.
<h3>How to illustrate the distance?</h3>
Based on the information given, after 3 hours, the distance of ship B will be:
= 20 + (17 × 3)
= 71.
A = 21 × 3 = 63
Well calculate the square root which will be:
A² + B² = 71² + 63²
= 5041 + 3969
= 9010
Therefore, ✓9010 = 94.92
Finally, the distance will be:
= (63 × 21) + (71 × 17) / 94.92
= (1323 + 1207)/94.92
= 26.65

Answer:
58.5
Step-by-step explanation:
230/4=57.5
57.5+1=58.5
The ratios that have a unit rate of 5 will be:
6 1/4 kilometers to 1 1/4 minutes.
1 kilometer to 1/5 minutes
1/3 kilometers to 1 2/3 minutes
<h3>How to calculate the value?</h3>
The ratios will be:
1. 6 1/4 to 1 1/4
= 6.25 : 1.25
= 5
2. 4 1/2 to 2
= 4 1/2 / 2
= 2.25
3. 4/5 to 5 minutes
4. 1 kilometer to 1/5 minutes
= 1 : 1/5
= 1 / 0.2
= 5
5. 3 1/10 : 3/10
= 10
6. 1/3 : 1 2/3
= 5
Therefore, the correct options are 1, 4 and 6.
