Answer:
<h2>x = 4.1 cm</h2>
Step-by-step explanation:
Use the Pythagorean theorem:
We have
Substitute:
<em>subtract 60.84 from both sides</em>
Answer:
The volume of the concentrated 80 gallons mixture is 20 gallons
The volume of water in the 80 gallons mixture is 60 gallons
Step-by-step explanation:
The given parameters are;
The content of Container A = The cleaner
The concentration of the cleaner = 20% solution
The content of Container B = Pure water
The concentration of the desired solution = 5%
The volume of the required solution = 80 gallons
Let x represent the volume of the concentrated solution and y represent the volume of water in the 80 gallons mixture
Therefore, we have;
20/100 × x + y×0 = 5/100×80
x + y = 80
y = 80 - x
20/100 × x + (80 - x)×0 = 5/100×80
0.2·x = 4
x = 4/0.2 = 20
x = 20 gallons
y = 80 - x = 80 - 20 = 60
y = 60 gallons
The volume of the concentrated solution (80 gallons mixture) = x = 20 gallons
The volume of water in the 80 gallons mixture = y = 60 gallons.
U didn’t put an image or at least i cant see it
Answer: (-5, -10)
Explanation: The x-intercept will be -5
and the y-intercept will be -10
The boxes can weight at most 5 grams less than the desired amount, so they can't be lighter than
grams
Similary, they can't weight more than 5 grams more than the desired amount, so they can't be heavier than
grams
So, the acceptable range is between 208 and 218.
