Someone please help, I don't understand how to do this 40 Pounds of trail mix consists of nuts at $2.40/lbs. and raisins at $4.40/lbs. If the trail
mix sells for $4.00/lbs. then how many pounds of each would be needed?

5lbs

Step-by-step explanation:

if you way as much as needed for nuts the add amount for raisins and mix

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
