That would be 644.8 / 31 = 20.8 feet / second
Answer:
There are a total of possible 1820 results.
Step-by-step explanation:
Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:


Total number of possible results:

Answer:
y = 3
Step-by-step explanation:
2y - 3 = 
square both sides to remove sqrt bracket
(2y - 3)^2 = (
)^2
simplify both sides
(2y - 3)(2y - 3) =
- 10y + 12
- 12y + 9 =
- 10y + 12
bring all value to left side
- 2y - 3 = 0
factor
(y - 3)(y + 1)
solve for y
y = 3, y = -1
When plugged back into the equation, only y = 3 is true
Set up the proportion line up minutes with minutes and miles with miles so it would be x over 60 36 over 45 and u get 48
