Answer:
the answer is 36654.52
Step-by-step explanation:
alright so if there are 86400 seconds in a day we substract 28800 bc thats how many seconds we have in 8 eight hours. That is 57600. divide it by 22, which is 2618.18. And multiply it by 14 bc thats how many times he blinks in 22 seconds. 36654.52
Step-by-step explanation:
24hours=86400seconds
8hours =28800seconds
Sam sleeps for 28800second
so 86400-28800=57600seconds.
Sam is awake for 57600seconds.
14blinks in 22seconds
xblinks in 57600seconds.
cross multiply
we have
22x = 806400
x=36654.5
Sam blinks for 36654.5 in a day

Solution (7,1)
Step-by-step explanation:
Use the elimination method
x + y=8
x - y=6
--------------Add
2x = 14
x = 7
Substitute x = 7 into x + y=8
7 + y=8
y = 8 - 7
y = 1

Answer:
2835x^5.
Step-by-step explanation:
By Binomial Theorem, T(r+1) = nCr * a^(r+1) * b^r.
Term 5 = 7C4 * x^5 * 3^4
= 35 * x^5 * 3^4
= 2835x^5.
