how much water should be added to 5 gallons of 50% acid solution to get a 20% solution?
Answer:
7.5 gallons
Step-by-step explanation:
2.5/5+x=0.2
This question is based on the concept of solving an equation. Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.
Given:
5 gallons of 50% acid solution to get a 20% solution.
According to question,
Let it be x gallons of water should be added to 5 gallons of 50% acid solution to get a 20% solution.
Now, forming the equation, we get,
0.50 ( 5 ) = 0.20 ( x + 5 )
Simplifying the equation.
We get,
2.5 = 0.2x + 1
1.5 = 0.2 x
x = 7.5
Therefore, 7.5 gallons of water would be added to 5 gallons of 50% acid solution to get a 20% solution.

8. Multiply the following:
c. (3s^4)(-6s^5)
The result of the multiplication is (-18s^9).
To multiply the two expressions (3s^4)(-6s^5), you can use the distributive property, which states that you can multiply a term by each of the terms inside a set of parentheses.
Using the distributive property, you can rewrite the expression as:
(3s^4)(-6s^5) = 3s^4 * -6s^5
Then, you can simplify the expression by combining like terms:
3s^4 * -6s^5 = (-18s^9)
So the result of the multiplication is (-18s^9).

When astronauts Neil Armstrong and Buzz Aldrin first walked on
the moon in 1969, they were able to bounce from step to step!
This is because the gravitational force of the moon is about
16.5% of that of the Earth. If you visited the moon,
weighing 100 pounds on Earth, what would your weight be?
Answer:
16.5 pounds
Step-by-step explanation:
16.5% as a decimal is 0.165
0.165 x 100 = 16.5
So in conclusion you will weigh about 16.5 pounds on the moon.

How do you decide where to shade an inequality whose boundary dose not go through the origin?
A. For <, shade above the boundary
B. If (0,0) is a solution, shade where (0,0) is
C. For >,shade below the boundary
D.If (0,0) is a solution, shade the boundary.
Answer:
I’m pretty sure that it is D because it says boundary and not just where it is at.
Step-by-step explanation:
If you have an equation for your graph you would substitute the y AND x with 0, you the solve the solution and if the solution is true then the space where (0,0) is located becomes the shaded area because that resembles the area in which everything is a positive solution with the equation. If it is false then the opposite area is then shaded because (0,0) doesn’t work with the problem.

Enter your answer in the box.
Answer:
18 units cubed. (18units³) also, replace 'units' with whatever units you were given (cm, inches, etc.)
Step-by-step explanation:
(the answer below is assuming each cube has a length of one unit. If they have a different length, then multiply the final answer by the length squared) (answer x length x length)
answer: there are six rows of cubes with 3 cubes in each row each. Each cube is 1x1, so 6 x 3 x 1 x 1 = 18. (with units): 18units³
also, replace 'units' with whatever units you were given (cm, inches, etc.)
