x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.
Step-by-step explanation:
Let,
x be the gift wrapped with wrapping paper.
y be the gifts in gift bag.
Time for wrapping one gift = 6.5 minutes
Time for doing 1 gift bag = 3 minutes
Total gifts = 19
Total time = 74.5 minutes
According to given statement;
x+y=19
6.5x+3y=74.5
x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.

Answer:
Number of bacteria after 36 hour (A) = 381 (Approx)
Step-by-step explanation:
Given:
Number of bacteria (p) = 2,000
Total time (n) = 36 hours
Decay rate = 4.5 % = 0.045 per hour
Find:
Number of bacteria after 36 hour (A)
Computation:
Number of bacteria after 36 hour (A) = 2,000[1-0.045]³⁶
Number of bacteria after 36 hour (A) = 2,000[0.955]³⁶
Number of bacteria after 36 hour (A) = 2,000[0.190599333]
Number of bacteria after 36 hour (A) = 381.19866
Number of bacteria after 36 hour (A) = 381 (Approx)
Ok so here it is
natural numbers: counting numbers like 1,2,3,4,5...
whole numbers: counting numbesr and 0, so 0,1,2,3,4
integers: negative counting numbers and 0, so -3,-2,-1,0,1,2,3...
ratioal numbers, things that can be represented in a/b
percent means parts out of 100 so
x%=x/100
that is a ratioal number
negatives are integers
