Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now
now=182
percent means parts out of 100 so
130%=130/100=13/10
182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140
140 students last year

Answer:
58.55Kg
Step-by-step explanation:
450 in Kg is 0.45.
0.45 + 4.5 = 4.95. 4.95 + 53.6 = 58.55.
We have been given an equation
that represents the distance an airplane travels in Miles (d) is related to the time in seconds (t).
A. Upon substituting t=1 in our equation we will get,

We can see that our plane is travelling at rate of 0.15 miles per second.

Therefore, plane is flying at the rate of 0.15 miles per second.
B. To find distance traveled by airplane in 30 seconds we will substitute t=30 in our given equation.

Therefore, plane will travel 4.5 miles in 30 seconds.
C. To find time it will take to travel 12.75 miles we will substitute d=12.75 in our given equation.



Therefore, plane will take 85 seconds to travel 12.75 miles.
