How large of a container would be needed to hold 800 g of water?

2 answers:

8 0

Since water has a density of 1 gram per cubic centimetre, then the container would need to be 800 cubic centimetres. if this container were a perfect cube,then the length of the side of the container would be equal to the cube-root of

The container would need to be 800 milliliters or 800 cubic centimeters, because there is one gram of mass in one cubic centimeter of water.

Find the value of y.

Phoenix [80]

$\boxed{y=6\sqrt{3}}$

<h2>Explanation:</h2>

For a better understanding of the problem I've built up two triangles from the given triangular shape. So these two triangles are similar. Therefore, we can solve this problem by using ratios and corresponding sides in this way:

$\frac{x}{3}=\frac{12}{x} \\ \\ x^2=36 \\ \\ x=\sqrt{36} \\ \\ x=6$

But our goal is to find y. Let's call w the height of the small triangle, then:

$w=\sqrt{6^2-3^2}=3\sqrt{3}$

Applying the concept of ratios again:

$\frac{y}{w}=\frac{x}{3} \\ \\ y=w \left(\frac{x}{3}\right) \\ \\ y=3\sqrt{3}\left(\frac{6}{3}\right) \\ \\ \boxed{y=6\sqrt{3}}$

Variable termes X-12-3X+22

adell [148]

Answer: x + 12 = 3x + -22

12 + x = 3x + -22

Reorder the terms:

12 + x = -22 + 3x

Solving

12 + x = -22 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

12 + x + -3x = -22 + 3x + -3x

Combine like terms: x + -3x = -2x

12 + -2x = -22 + 3x + -3x

Combine like terms: 3x + -3x = 0

12 + -2x = -22 + 0

12 + -2x = -22

Add '-12' to each side of the equation.

12 + -12 + -2x = -22 + -12

Combine like terms: 12 + -12 = 0

0 + -2x = -22 + -12

-2x = -22 + -12

Combine like terms: -22 + -12 = -34

-2x = -34

Divide each side by '-2'.

x = 17

Simplifying

x = 17

Molodets [167]

Answer:

24/25

Step-by-step explanation:

Step 1: Define systems of equation

10x - 16y = 12

5x - 3y = 4

Step 2: Rewrite one of the equations

5x = 4 + 3y

x = 4/5 + 3y/5

Step 3: Solve for y using Substitution

Substitute 2nd rewritten equation into 1: 10(4/5 + 3y/5) - 16y = 12
Distribute the 10 to both terms: 40/5 + 30y/5 - 16y = 12
Simplify the fractions down: 8 + 6y - 16y = 12
Combine like terms (y): 8 - 10y = 12
Subtract 8 on both sides: -10y = 4
Divide both sides by -10: y = 4/-10
Simply the fraction down: y = -2/5

Step 4: Substitute y back into an original equation to solve for x

Substitute: 5x - 3(-2/5) = 4
Multiply: 5x + 6/5 = 4
Subtract 6/5 on both sides: 5x = 14/5
Divide both sides by 5: x = 14/25

Step 5: Check to see if solution set (14/25, -2/5) is a solution.

Substitute into an original equation: 10(14/25) - 16(-2/5) = 12
Multiply each term: 28/5 + 32/5 = 12
Add: 12 = 12

Here, we see that x = 14/25, y = -2/5 and solution (14/25, -2/5) indeed works.

Step 6: Find x - y

x = 14/25

y = -2/5

Substitute: 14/25 - (-2/5)
Simplify (change signs): 14/25 + 2/5
Add: 24/25

Hope this helped! :)
