Answer: 22.5 minutes
Step-by-step explanation: Daisy ran 12 miles in 90 minutes so we should first figure out how many minutes it took her to run a mile. So 90/12 would get us that. 90/12 turns out to be 7.5 minutes per mile. Since she runs at a constant rate we multiply 7.5 by 3 (7.5*3) to get 22.5 minutes for 3 miles.
When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. To add the fractions with unlike denominators, rename the fractions with a common denominator. So you could find the lowest common multiple and multiply the numerator and denomenator by it and then you can carry on with the rest of the equation. If this doesn’t make sense and you need these information for an equation I suggest you take a picture of it and upload it so someone can help you with it specifically
Answer:
Step-by-step explanation:
We are given that a student needs to make a square cardboard piece.
Perimeter of cardboard should be equal to atleast 92 inches
We have to find that which shows reasonable domain for f(s)
Let s be the side of square cardboard
We know that perimeter of square =f(s=)
Then, perimeter of cardboard=
Dividing by 4 on both sides
Hence, the domain of function
Therefore, option d is true.
