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
55 because alternate interior angles are congruent and then you can do some basic algebra
0.16 as a fraction becomes 16/100. This can be simplified to 4/25.
None of those are the right answer, though 1/6 as a decimal is 0.16666666... (the 6s repeat forever) so option C is what they're looking for.
The answer is y=2x+1. 1 being the y intercept and 2x being the slope
When you see this kind of question use « BODMAS »
1.Add the 2 digits which is 3+7=10
2.Add the digits inside which is 0.7+1.3=2
3.Add the inside and outside
3+7(0.7+1.3)
10(2)=20
