Negative bc negative times positive is negative
Answer:
Total cooking time = 20t + 15
The expression 15t + 20 is wrong.
Step-by-step explanation:
weight of chicken = t lbs
cook time per lb = 20 minutes
This means that:
1 lb weight requires a cooking time of 20 minutes
1 lb = 20 minutes
∴ t lbs = 20 × t = 20t minutes.
We were also told that each chicken required an extra cooking time of 15 minutes, in addition to the total cooking time due to the weight. Therefore, the total cooking time is calculated thus:
Total cooking time = cooking time due to weight + 15 minutes
Total cooking time = 20t + 15
Hence the expression 15t + 20 is wrong, due to the explanation given above.
We estimate that 25/75 = 1/3 of the fish in the pond are marked.
So an estimate would be 30 / 1/3 = 30*3
= 90 answer
The number of different codes does this lock provides is 360.
Given that,
- There is the combination lock having push buttons from A to F (6 buttons)
- Out of this, four should be in any order.
- Also, the push button should not be used more than once.
Based on the above information, here we use permutation which is as follows:
= 360
Therefore we can conclude that the number of different codes does this lock provides is 360.
