Which fraction is equivalent to 5/12 + 2/3

Answers

Answer:

5/12 + 8/12 = 13/12 = 1 1/12

Step-by-step explanation:

This is the answer because:

1) You have to add the fractions, in order to add the fractions you have to find the common denominato.

2) The common denominato is 12 because 2 x 4 = 8 and 3 x 4 = 12. Therefore, 2/3 = 8/12.

3) Finally, once you add 5/12 and 8/12, you should get 13/12 which is also equal to 1 1/12.

Prism: V = Bh
Cylinder: V = πr²h​

Answers

Answer:

452.16 in. or 144π if the answer needs to be in terms of pi.

Step-by-step explanation:

In this case, all of the information is given to you. You can determine this is a cylinder because of its circular bases. Your height is given on the side as 9in. Your radius is given on the base as 4in. You can tell that this value is the radius and not the diameter because the line only covers half of the circular base. If the line went from one edge to the other, you would need to divide the given value by 2. From there, you can just plug the numbers into the proper equation.

V = πr²h​

V = π(4)²(9)

V = 452.16 or 144π

It’s system of equations

A large wooden box, as shown, has a volume of 4352 ft3. The box is a right square prism with a base with sides that each measure 16 ft. What is h, the height of the box?

Answers

Volume of a Prism

To find the volume of a prism, we can use the following formula:

[tex]V=base\hspace{3}area*height[/tex]

Although this formula is typically used to find the volume of a prism, we can also use it to find the base area or height, as long as we re-arrange it accordingly.

For a rectangular prism, the base area is solved using the following formula:

[tex]A=lw[/tex] ⇒ where l is the length and w is the width

Solving the Question

We're given:

V = 4352 ft³l = 16 ftw = 16 ftWe need to solve for the height of the box.

First, find the base area:

[tex]A=lw\\A=16^2\\A=256[/tex]

Therefore, the base area is equal to 256 ft².

Now, modify the volume formula to isolate the height:

[tex]V=base\hspace{3}area*height[/tex]

⇒ Divide both sides by the base area:

[tex]\dfrac{V}{base\hspace{3}area}=\dfrac{base\hspace{3}area*height}{base\hspace{3}area}\\\\\dfrac{V}{base\hspace{3}area}=height\\\\height=\dfrac{V}{base\hspace{3}area}[/tex]

⇒ Plug in the given values:

[tex]height=\dfrac{4352}{256}\\\\height=17[/tex]

Therefore, the height of the box is 17 ft.

The height of the box is 17 ft.

Using trigonometric identity sin²θ+cos²θ=1, the given identity is proved.

The given trigonometric identity is 1-2cos²x = 2sin²x-1.

What are trigonometric identities?

Trigonometric Identities are the equalities that involve trigonometry functions and holds true for all the values of variables given in the equation. There are various distinct trigonometric identities involving the side length as well as the angle of a triangle.

Using trigonometric identity sin²θ+cos²θ=1

Here, 1-2cos²x = 2sin²x-1

⇒ 1+1=2sin²x+2cos²x

⇒ 2=2(sin²x+cos²x)

⇒ 2=2(1)

⇒ 2=2

LHS=RHS

Which graph represents the following system of inequalities? y < -3x+5 y < x+2 y < -1

Answers

Answer:

The attached graph represents the system

Step-by-step explanation:

Let us describe the graph of each line

In y < -3x + 5

∵ The sign of inequality without =

∴ The line represents it must be dashed

The slope-intercept form of the inequality is y < m x + b, where m is the slope and b is the y-intercept

∵ y < -3x + 5

∴ m = -3 and b = 5

∴ The direction of the line is to the left and intersect the y-axis at (0, 5)

y < -3x + 5 represented by the green line

∵ The sign of inequality is <, then the shading is under the green line

In y < x + 2

∵ The sign of inequality without =

∴ The line represents it must be dashed

∴ m = 1 and b = 2

∴ The direction of the line is to the right and intersect the y-axis at (0, 2)

y < x + 2 represented by the blue line

∵ The sign of inequality is <, then the shading is under the blue line

In y < -1

∵ The sign of inequality without =

∴ The line represents it must be dashed

∴ m = 0 and b = -1

∴ The line is horizontal and intersects the y-axis at (0, -1)

y < -1 represented by the red line

∵ The sign of inequality is <, then the shading is under the red line

∵ The shading of the three inequalities is under the lines

∴ The solutions of the system of inequalities lie in the common

   shaded part under the three lines

∴ The attached graph represents the system

A restaurant manager bought a case of 12 bottles of water. He paid 90p per bottle. He sold 1/4 of the bottles for £2.10 per bottle and the rest of the case for £2.40 per bottle. a) How much profit did he make? b) Write the profit as a percentage.

Answers

Step-by-step explanation:

12 bottles for 0.90 per bottle = 12×0.90 = £10.80 as initial cost.

1/4 of 12 = 12×1/4 = 12/4 = 3 bottles

so, 3 bottles are sold for £2.10 per bottle = 3×2.1 = £6.30

the rest (12-3) 9 bottles are sold for £2.40 per bottle = 9×2.4 = £21.60

so, the total sales was 6.3 + 21.6 = £27.90.

the profit is then sales minus initial cost :

27.9 - 10.8 = £17.10

1% of the initial cost is 10.8/100 = 0.108

how often does 1% fit into the total profit ?

17.1/(10.8/100) = 17.1×100/10.8 = 158.3333333...%

so, the profit is 158.3333333...% of the initial cost.

Answers

The area of the equilateral triangular pyramid is the amount of space on it

The total surface area is 107 square feet

How to determine the total surface area?

The given parameters are:

Base (b) = 6 feet

Slant height (l) = 10 feet

The lateral surface area is calculated using:

L = 1.5bl

So, we have:

L = 1.5 * 6 * 10

Evaluate the product

L = 90

The total surface area is calculated using:

T = L + 0.25√3b^2

So, we have:

T = 90 + 0.25√3 * 6^2

Evaluate

T = 107

Hence, the total surface area is 107 square feet

Cows usually eat only grass and other plants, but farmers had been feeding them a meat and bone mixture that made the cows plumper. But somehow, at least one batch of the mixture had become contaminated with what was then an unknown killer: a prion.By 1993, British farmers were reporting up to one thousand new cases of BSE a week. Governments all around the world reacted by increasing testing for the disease and not allowing any cows to be eaten if they were at risk of having the disease. As sheep can also get a prion disease called scrapie, they were tested as well. Farmers were angry that they were losing their livestock, and nobody knew how to protect cows and people from the disease.Consumers were also in a panic when they learned about BSE, and for a very good reason: prions are infectious. If you eat a prion from a "mad cow or sheep, you are at risk for developing a human version of BSE. The public felt betrayed that their governments had underreacted to the problem or covered it up.Eventually, in 1997, governments began to ban farmers from feeding their livestock high-risk meat and bone mixtures. With that ban, the epidemic quickly peaked, and by 2010 had largely disappeared. Over the years, half a million cows and two hundred people had been killed by prions.In the end, the BSE epidemic was a watershed moment, or turning point, in public health. Citizens were enraged at their governments for having kept prions a secret. Governments, who had lost the public trust, struggled to find the best way to communicate health risks without creating unnecessary panic.How does the author's use of chronology help support the idea that the BSE epidemic was a watershed moment, or turning point, in government use of law to support public health?A.The author lays out a timeline to show how scientific discoveries made governments less likely to make laws for public health.B.The author makes it clear that prions were always known to be dangerous and that scientists discovered them to be the cause of mad cow disease.C.The author discusses how the mad cow disease epidemic ended only about twenty-five years after it first became a problem.D.The author shows how frustrated people were that nothing was done about a disease until over ten years after it was discovered.
