Answer:
y = 10√16) = 40
Step-by-step explanation:
This says, "y is proportional to the square root of x." We are told that y = 60 when x = 36. Find the formula for this function. Then, determine what value y will take on when x = 16.
y = k√x becomes 60 = k√36, or 60 = 6k. Then k must be 10, and the formula is y = 10√x.
If x = 16, y = 10√16) = 40
Answer:
1.25 minutes, or 1 minute 15 seconds
Step-by-step explanation:
We know that is speed is 0.4 pages per 0.5 minutes. This is 0.8 pages per 1 minute. If we divide 1/0.8, we get 1.25 or 1 minute 15 seconds.
90 dimes = $9 because 10 dimes = $1
