0=44-25t-5t^2
t^2+2t-8=0
(t+4)(t-2)=0
t=-4 (not a solution) or t=2
Answer: after 2 seconds
Answer:
2 gallons
Step-by-step explanation:
4 quarts = 1 gallon
2 pints in a quart
2 cups in a pint
8 ounces in a cup
1/2 gal of orange juice

79.50 x .06 = 4.77
79.50 + 4.77 = $84.27
The total cost was $84.27
Answer:
x= -19
y= -14
Step-by-step explanation:
Substitution.
It tells you what y is already. You substitute that into the second equation and then solve. Then you use that answer and substitute it back into the first equation's x, and then you'll get your full answer.

The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the <em>measured</em> magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
(1)
Where:
- Measured magnitude, in millimeters.
- Possible magnitude, in millimeters.
- Uncertainty, in millimeters.
If we know that 
and 
, then the lower bound of the measurement is:
The lower bound of the measurement is 65.5 millimeters.
