The inequalities are; 5¹/₄ tons = 10500 pounds; 1/2 ton + 3/4 ton > 2800 pounds; 2 tons > 60000 pounces; 1¹/₄tons > 20000 ounces
How to find Inequalities?
1) 5¹/₄ tons when converted to pounds is 10500 pounds.
Thus; 5¹/₄ tons = 10500 pounds.
2) 1/2 ton + 3/4 ton = 5/4 tons
Converting 1.25 to tons gives 2500 tons. Thus;
1/2 ton + 3/4 ton > 2800 pounds
3) Converting 2 tons to Ounces gives 64000 ounces. Thus;
2 tons > 60000 pounces.
4) 1¹/₄tons - ¹/₂ton = ³/₄ tons
Converting to ounces gives 24000 ounces
Thus; 1¹/₄tons > 20000 ounces

The correct number line which represents the solution set for the inequality is shown in option 2.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
We have to given that;
Inequality is,
⇒ 2x - 6 ≥ 6 (x - 2) + 8
Now, We cam simplify as;
⇒ 2x - 6 ≥ 6 (x - 2) + 8
⇒ 2x - 6 ≥ 6x - 12 + 8
⇒ 2x - 6x ≥ - 12 + 8 + 6
⇒ - 4x ≥ 2
⇒ 4x ≤ - 2
⇒ x ≤ - 1/2
⇒ x ≤ - 0.5
Hence, The correct number line which represents the solution set for the inequality is shown in option 2.

Considering it's volume of 113 cm³, the approximate radius of the sphere is given by:
A. 3 cm
What is the volume of an sphere?
The volume of an sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
In this problem, we have that V = 113 cm³, hence the radius in cm is given as follows:
[tex]V = \frac{4\pi r^3}{3}[/tex]
[tex]113 = \frac{4\pi r^3}{3}[/tex]
[tex]r^3 = \frac{113 \times 3}{4\pi}[/tex]
[tex]r = \sqrt[3]{\frac{113 \times 3}{4\pi}}[/tex]

A bag contained $24.20 worth of coins. There were 20-cent and 50-cent coins only. The number of 20-cent coins was 5 fewer than the number of 50-cent coins. How many coins were there in the bag
Answers
Answer:
Their will be 2 coins in allThere were 67 coins in the bag, 36 of which were 50-cent coins and 31 of which were 20-cent coins.
Let x be the number of 50-cent coins in the bag,
And y be the number of 20-cent coins.
From the problem,
we know that y = x - 5,
Since there were 5 fewer 20-cent coins than 50-cent coins.
We can also set up an equation for the total value of the coins in the bag,
⇒ 0.5x + 0.2y = 24.20
Now we can substitute y = x - 5 into the equation,
⇒ 0.5x + 0.2(x - 5) = 24.20
Simplifying, we get,
⇒ 0.7x - 1 = 24.20
⇒ 0.7x = 25.20
⇒ x = 36
So there were 36 50-cent coins in the bag.
Using y = x - 5,
We can find that there were 31 20-cent coins.
Therefore, there were a total of 67 coins in the bag (36 + 31 = 67).

Which point is not included in the solution set for the inequality? (–1, 3) (0, 4) (1, 5) (2, 4)
Answers
The point that is not included in the solution set for the inequality in the graph is (-1, 3).
How to explain the graph?In the information given, (h, k) is the vertex point. In the graph, the vertex point will be (1, 2). The equation will be:
y = a(x + 1)² + 2
By the point of the graph(0, 3) the value of a will be:
3 = a(0 - 1)² + 2
3 = a + 2
a = 3 - 2
a = 1
The equation this becomes:
y = 1(x - 1)² + 2.
y = x² - 2x + 1 + 2
y = x² - 2x + 3
Therefore, the point that is not included in the solution set for the inequality is (-1, 3).

Solve the following system of equations
3x - 4y + z = -5
x-y-z = -10
6x - 8y + 2z = 10
Answers
Notice that the left side of the third equation is 2 times the left side of the first equation:
6x - 8y + 2z = 2 (3x - 4y + z)
The first equation says
3x - 4y + z = -5
while the third equation would reduce to
2 (3x - 4y + z) = 10 ⇒ 3x - 4y + z = 5
but -5 ≠ 5, so there is no solution to the system.
A rectangular piece of metal is 10 in longer than it is wide. Squares with sides 2 in long are cut from the four corners and the flaps are folded upward to form an open box. If the volume of the box is 1102in^3, what were the original dimensions of the piece of metal?
Answers
The length and width of the piece of metal are 20 and 30 inches respectively.

height of box = 2
The volume of the box is 1102 in³;
