Answer:
The correct option is D) 43 items.
Step-by-step explanation:
As we know that total given time is ,
,
Out of which cashier spends 40 seconds to process the customer's payment.
So the remaining time = (126 - 40) = 86 secs.
And the remaining time is used to scan the item and so that we can calculate here the no items scan is = (86 ÷ 2) = 43.
Therefore we can say that 43 items are being purchased.
opposite means the sign changes (from positive to negative or vice versa)
since a rational number includes both positives and negatives, then the opposite of a rational is also a rational.
For example: 
is a rational number. Its opposite is 
, which is also a rational number.

Answer: YES
Number 2 is D. The pattern is quite simple, basically the formula for direct variation is y=kx, so in number 2 the problem shows -12x=6y, so then you would end up dividing the numbers, and this should you solve your other answers.

Answer:
128 km²
Step-by-step explanation:
a²+b²=c²
So, one of the sides equals 128 square rooted, because 8²=64, and 64 times 2 equals 128. The area of a square is side times side, so it's side². So, instead of simplifying the square root of 128, get rid of the square root. The answer is 128 km²
