This problem can be solved through simple arithmetic
progression
Let
a1 = the first term of the sequence
a(n) = the nth term of the sequence
n = number of terms
d = common difference
Sn = sum of all terms
given
a1 = 12
a2 = 16
n = 10
d = 16 -12 = 4
@n = 10
a(n) = a1 + (n-1)d
a(10) = 12 + (9)4
a(10) = 48 seats
Sn = (n/2) * (a1 + a(10))
Sn = 5* (12 + 48)
Sn = 300 seats
Therefore the total number of seats is 300.
Answer:
m = - 16/10
= - 1.6
Step-by-step explanation:
m2 + 8m
(the - 16 here is divided into 10 m's as you can see in m2 and 8m)
So, in order to find out what 1m is, you have to <em>divide</em> - 16 by 10, which gives you - 1.6
Good luck!
Answer:
460 m
Step-by-step explanation:
Boundary = perimeter
Perimeter = 2(length + width)
= 2(150 + 80)
= 2(230)
= 460 m
The greatest common factor is found by finding the product of common primes.
91=7*13, 104=2*2*2*13 so the gcf of 91 and 104 is 13. Since the highest power of x and y in both terms is 1, the hcf for the variables is just xy
13xy
