Answer:
Step-by-step explanation:
As it is a second order equation, it means that it has two possible answers and they are
and
.
The famous quadratic formula for solving any second order equation is the following:

Where a is the coefficient of
, b is the coefficient of x, and c is the free term. In other words,

as the equation should be in the following form:

Therefore the possible answer should be the following,


by dividing the numerator and denominator by 2, we can deduce the following,
Answer:
a. 47.6mph (distance divided by time = speed. divide each rowers distance by their speed, then add them all)
b. 1.26 minutes per mile (i used a calculator so i dunno how to explain)
let me know if this is right or not :)
Answer:they would pay a total amount of $9
Step-by-step explanation:
Scott and Tom rent a boat at Stow Lake. They start at 10:15 and end at 11:45. The number of hours for which they rented the boat would be
11:45 - 10:15 = 1 hour 30 minutes = 1.5 hours.
Converting to minutes, It becomes
60 + 30 = 90 minutes.
The boat rental costs $1.50 for every 15 minutes. Therefore, the total amount of money that they would pay is
90/15 × 1.5 = $9
Answer:
2/3 or 2 to 3
