Answer:
The amount of water to be added is ¹/₄ gallon
Step-by-step explanation:
Given;
amount of pure antifreeze at 100% = 1 gallon
let the amount of water to be added with 0% antifreeze = (x) gallon
then, the amount of mixture at 80% antifreeze = (x + 1) gallon
For conservation of mass, we will have the following equation;
(1 x 1) + (0)(x) = 0.8(x +1)
1 = 0.8x + 0.8
0.8x = 1 - 0.8
0.8x = 0.2
x = 0.2 / 0.8
x = ²/₈
x = ¹/₄ gallon
Therefore, the amount of water to be added is ¹/₄ gallon
Whats the the question i can't write it in standard form if i have nothing to write
Here is the full question
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second.
Equation:
y=-16x^2+153x+98
Answer:
10.2 seconds
Step-by-step explanation:
Given equation :
shown the expression of a quadratic equation
Let y =0
∴
0 = 
where;

Using the quadratic formula:

replacing it with our values; we have:

OR 
OR 
Hence, we go by the positive value since, is the time that the rocket will hit the ground.
x= 10.17
x = ≅ 10.2 seconds
Therefore, the rocket will hit the ground, to the nearest 100th of second. = 10.2 seconds
