Answer:
1083 seats
Step-by-step explanation:
this is an arithmetic sequence :
an = an-1 + c
in our case
a1 = 10 (10 seats in the first row)
a2 = a1 + 1 = 10 + 1 = 11
a3 = a2 + 1 = a1 + 1 + 1 = 10 + 1 + 1 = 12
an = an-1 + 1 = a1 + (n-1)×1 = a1 + n - 1 = 10 + n - 1 = 9 + n
a38 = a1 + 37 = 10 + 37 = 47 seats.
altogether this means the sum of the arithmetic sequence of a1 to a38.
the general sum of an arithmetic sequence from a1 to an is
n×(a1 + an)/2
in our case
38×(10 + 47)/2 = 19×57 = 1083 seats
Is means =
'of' means multiply
percent means parts out of 100 so 48%=48/100=4.8/10=0.48/1=0.48
so it is
336=0.48 times something
divide both sides by 0.48
700=something
the numbe ris 700
16%
if you multiply 25 grams buy 4 you get 100 (100%) then you mulitply 4 by 4 which gives you 16 (16%)
