we are given
displacement is
now, we are given
rigonometric function appearing in an equation must be dimensionless
so,
must be dimensionless
so, unit of x and unit of 'a' must be same
so, unit of 'a' will be unit of displacment
and unit of displacemet is metre(m)
so, unit of 'a' will be metre(m).............Answer
Answer:
12,500 people went to the fair.
Step-by-step explanation:
Set up an equation:
Variable x = number of people who went to the fair
12/100 = 1500/x
Cross multiply:
12 × x = 100 × 1500
12x = 150000
x = 12500
Check your work:
12500 × 12%
Convert percentage into a decimal:
12500 × 0.12
1500
1500 people received water bottles so this is correct!
