Answer:
Therefore, beats per minute did increase for 36.
Step-by-step explanation:
48: 2/3=x:1
48=2/3 × x
x=3/2×48
x=72
81:3/4=x:1
81=x×3/4
x=4/3×81
x=108
Therefore, beats per minute did increase for 36.
Notice that
and given that 10 is closer to 9, it's clear that
is probably closer in value to 3 then to 4. (The actual value is indeed about 3.162.)
