**Answer:**

32 gallons of water

**Step-by-step explanation:**

If the total tank can hold up to 80 gallons of water, it is considered full when it contains 80 gallons. When the tank is 40% full, it has 40% of 80 gallons in the tank. 40% of 80 is 40/100*80=8*4=32 gallons of water.

which statement describes the solution to the system of equations?

**Answer:**

The solution is (3, 5).

**Step-by-step explanation:**

The solution to a system of equations is a point that satisfies both equations - that is, a point that you can input to *both* equations that makes *both* of them true. On a graph, you can find this solution by searching for the place where the lines intersect.

In this case, it looks like the lines intersect at the point **(3, 5)**, so this is our final answer. Hopefully that's helpful! :)

The solution is (3, 5), this statement describes the solution to the **system of equations**.

Option B is correct.

Here, we have,

The statement that describes the solution to the **system of equations** where two lines intersecting at (3, 5) is:

"The point of intersection of the two lines is (3, 5)."

When two lines **intersect** at a single point, that point is the solution to the **system of equations**.

In this case, the **coordinates** (3, 5) represent the x and y values where the two lines cross each other.

This means that both equations are satisfied when x = 3 and y = 5.

The solution to a **system of equations** is a point that satisfies both equations - that is, a point that you can input to both equations that makes both of them true.

On a graph, you can find this solution by searching for the place where the lines intersect.

"The **point of intersection** of the two lines is (3, 5)."

Option B is correct.

I need the function for the volume of the box for number 1

**Answer:**

**Step-by-step explanation:**

The volume of a rectanguiar shape like this one is V = L * W * H, where the letters represent Length, Width and Height. Here L is the longest dimension and is 28 - 2x; W is the width and is 22-2x; and finally, x is the height. Thus, the volume of this box must be

V(x) = (28 - 2x)*(22 - 2x)*x

and we want to maximize V(x).

One way of doing that is to graph V(x) and look for any local maximum of the graph. We'd want to determine the value of x for which V(x) is a maximum.

Another way, for those who know some calculus, is to use the first and second derivatives to identify the value of x at which V is at a maximum.

I have provided the function that you requested. If you'd like for us to go all the way to a solution, please repost your question.

Lisa has a certain amount of money. She spent $39 and has 3/4 of the original amount left. How much money did she have originally

We know that she spent $39, and has 3/4 of the original amount left. Our goal is to find the original amount. We can use the equation. x - 39 = 3/4x. Once we subtract x on the left hand side, we get -39 = -1/4x. Once we multiply -39 by -4, we get 146. She originally had $156.

A cone has a radius of 5. 1 inches and a height of 5 inches. What is the volume of the cone? Use 3. 14 for pi. Round to the nearest tenth. 25. 0 inÂł 75. 0 inÂł 125. 4 inÂł 136. 1 inÂł.

The correct option is **D**. **136.1 cubic inches**.

Given, **Radius **of cone is 5.1 inches.

**Height **of cone is 5 inches.

We know that, **volume **of cone,

[tex]V=\frac{1}{3} \pi r^{2} h[/tex]

Here r is the **radius **of cone and h is its **height**.

on putting the value of r and h, we get

[tex]V=\frac{1}{3} \times3.14\times(5.1)^{2} \times5[/tex]

[tex]V=\frac{1}{3} \times3.14\times26.01\times5[/tex]

Or, [tex]V=136.119 \ cubic \ inches[/tex].

The **volume **of **cone **to the nearest **tenth **is **136.1 cubic inches**.

Are all real numbers either rational or irrational?

**Answer:**

Yes. All real numbers are either rational or irrational.

**Step-by-step explanation:**

The set of all irrational numbers is commonly defined as the set of all real numbers that are not rational.

Let [tex]\mathbb{R}[/tex] denote the set of all real numbers. Let [tex]\mathbb{Q}[/tex] denote the set of all rational numbers.

For any given real number [tex]x[/tex] ([tex]x \in \mathbb{R}[/tex],) either [tex]x\![/tex] is rational ([tex]x \in \mathbb{Q}[/tex]) or [tex]x\!\![/tex] isn't rational ([tex]\lnot (x \in \mathbb{Q})[/tex], such that [tex]x \not\in \mathbb{Q}[/tex] and thus [tex]x \in (\mathbb{R} \backslash \mathbb{Q})[/tex].)

Assume that [tex]x[/tex] isn't a rational number. By the definition of rational numbers, since [tex]x\!\![/tex] is a real number but not a rational number ([tex]x \in (\mathbb{R} \backslash \mathbb{Q})[/tex],) [tex]x\![/tex] would be an irrational number.

Therefore, either [tex]x[/tex] is rational or [tex]x\![/tex] is irrational. Every real number would either be rational or irrational.

An inground swimming pool contains 2.3 times 10 Superscript 4 units of water. Which unit of measure was used?

teaspoons

cubic centimeters

fluid ounces

gallonsCassie is measuring the volume of her fish tank to find the amount of water needed to fill it. Which unit of measurement should she use to eliminate the need to write the value in scientific notation? teaspoons inches gallons pounds

**Answer:**

a) gallons

b) gallons

**Step-by-step explanation:**

1 fluid ounce is about 6 teaspoons or 30 cubic centimeters or 1.8 cubic inches. 2.3×10^4 fluid ounces is less than 1 cubic yard. We suspect the pool is much larger than that, so its volume is probably measured in **gallons**.

__

b)Of the units listed, only *teaspoons* and *gallons* are units of volume. As we saw in the previous problem, a teaspoon is a pretty small volume in relation to the size of most fish tanks. The appropriate unit of measure would be **gallons**.

Seven tickets for a Broadway show cost $385. How much will only 4 tickets cost?

**Answer:**

That seems a little hard-

**Step-by-step explanation:**

**Answer:**

**$220**

**Step-by-step explanation:**

If seven tickets cost 385, then 1 ticket costs one-seventh of that amount, so we divide it by 7 to see how much one ticket costs.

385/7 = 55

One ticket is $55. To find out how much 4 tickets cost, multiply 55, the price of one ticket, by 4.

55 * 4 = 220

Lena is converting StartFraction 2 Over 25 EndFraction to a percent. What should she multiply the numerator and denominator of the fraction by to find the percent?

4

100

**Answer:**

4 if im right:)

**Step-by-step explanation:**

**Answer:**

A percent is a number out of 100, so you'd want to multiply the denominator to get 100. In this case, 25 would have to be multiplied by 4 to get 100. To keep the fractions equal to each other, you have to multiply the numerator by the same thing. 2*4=8. Therefore, your fraction would be 8/100 or 8%
