Answer:
23/10 gallons
Step-by-step explanation:
Alicia uses 3/4 gallon of paint to paint her room.
Alicia use = 3/4 gallon of paint
Becca uses for 4/5 gallon more than Alicia to paint her room.
Becca uses = Alicia (3/4 gallons ) + 4/5
Becca uses =
Total paint used together = Aliccia used + Becca used
Add like fractions 3/4 + 3/4 becomes 6/4
Make the denominators same
Divide top and bottom by 2

Answer:
Step-by-step explanation:
This quadratic models the parabolic motion equation
where h is the height of the object after the motion occurs, a is the pull of gravity, v(i) is the initial vertical velocity of the object, and h(i) is the height from which the object was initially launched. If we are looking for when the ball hits the ground, h = 0, because the height of an object on the ground has no height at all (or 0 height). To find the time the object was in the air, factor the quadratic and solve for the values of t.
Two factors of 4 that add up to be 3 and multiply to be 4 are -1 and 4. So t=-1 and t = 4. Since we know that time can never be negative, then t = 4 seconds.
