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
Answer: Each chair weights 9.73 lb.
Step-by-step explanation:
235.68 = 8c + 157.84
Subtract 157.84 from each side
77.84 = 8c
Divide each side by 8
9.73 c
Area = width x length
If the area is 48 and width is 6, you can do
Length = area/width
Length = 48/6
Length = 8
Perimeter = length x 2 + width x 2
Perimeter = 8x2 + 6x2
Perimeter = 16 + 12
Perimeter = 28 feet
Point slope form will give you the point
y - y1 = m(x- x1)
when the equation says -, the number is positive. when the equation says +, the number is negative
in this case the point is (-6,5)
