Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

To determine the total cost of the game, we can set up an equation based on the given information.

Let's assume the total cost of the game is represented by the variable "x."

According to the problem, Tom has saved $18, which is two-thirds of the total cost. We can express this as the equation:

(2/3) * x = $18

To solve for x, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2:

(3/2) * (2/3) * x = (3/2) * $18

x = $27

Therefore, the game costs $27.

Based on the given probability of 2/20 (0.1), the likelihood of selecting a black pen from Mrs. Galvan's drawer of 20 pens is best described as:

A. unlikely

Since there are only 2 black pens out of 20 total pens, the probability of randomly selecting a black pen is fairly low at 0.1 or 10%. Events with probabilities less than 0.5 (50%) are generally considered unlikely. Having only a 1 in 10 chance of an outcome makes that outcome unlikely.

B. likely

This option is incorrect. With a probability of 0.1 or 10%, selecting a black pen is unlikely, not likely. An outcome is considered likely if it has a probability of greater than 0.5 (50%).

C. neither unlikely nor likely

This option is also incorrect. While probabilities close to 0.5 could be described as neither unlikely nor likely, a probability of 0.1 is clearly on the unlikely side. Events with probabilities less than 0.5 are classified as unlikely.

In summary, given that there is only a 10% chance (2 out of 20) of randomly selecting a black pen from Mrs. Galvan's drawer, the likelihood of this outcome is best described as unlikely rather than likely or neither unlikely nor likely. A probability of 0.1 is well below the 0.5 threshold that would make an outcome considered likely. Therefore, the answer is A: unlikely.

Hope this explanation has helped clarify why A is the best choice! Let me know if you have any other questions.

Answer:

A. Unlikely

Step-by-step explanation:

Getting a black pen is lesser than the 50%, which is 10/20. Not more nor equal, so the answer is A, unlikely.

Answer:

The surface area of the cylinder is equal to: C. 440 m².

How to calculate surface area of a cylinder?

Mathematically, the surface area (SA) of a cylinder can be calculated by using this formula:

SA = 2πrh + 2πr²

Where:

h represents the height.

represents the radius.

By substituting the given parameters into the surface area of a cylinder formula, we have;

Surface area (SA) of cylinder = (2 × 3.14 × 5 × 9) + 2 × 3.14 × 5²

Surface area (SA) of cylinder = 282.6 + 157

Surface area (SA) of cylinder = 439.6‬ ≈ 440 square meters.

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

V=d/t

V1=1/8 × 12/1=12/8=3/2

V2=3/8 × 9/1 =27/8

Common denominator:

3/2=1 1/2 and 27/8= 24 3/8

so second pool because 24 3/8 is greater

Answer:

The side length of the pool is approximately 12.2 feet.

Step-by-step explanation:

Estimation

The area of a square of side length a is given by:

\(A = a^2\)

If the area is known, then the side length is:

\(A = a^2\)

We are given Zoeys' pool is a square with an area of 150 square feet.

Then:

\(a=\sqrt{150}\)

Since 150 does not have an exact square root value, we must estimate by successive approximations.

First, find the two integers perfect squares between which it's located.

Note \(12^2=144\), \(13^2=169\)

The square root is between 12 and 13.

Since 150 is closer to 144 than to 169, the square root is closer to 12 than to 13.

Now we increase from 12 to 12.1:

\(12.1^2=146.41\)

\(12.2^2=148.84\)

\(12.3^2=151.29\)

Note that 150-148.84 = 1.16 and 151.29-150 = 1.29

The answer is closer to 12.2 than to 12.3, thus:

The side length of the pool is approximately 12.2 feet.

Answer:

-17

Step-by-step explanation:

I will represent the question mark with the variable \(x\).

\(x - 11 + 12 = -16\)

To solve for \(x\), we need to isolate it.

To do this, subtract 12 from both sides.

\(x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28\)

Then, add 11 to both sides.

\(x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17\)

\(x = -17\)

So, the integer that makes the equation true is -17.

The ratio equivalent to the ratio 4:16 is 1:4.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

The given ratio is 4:16.

Here, 4:16 can be written as 4/16

Divide both the numerator and denominator by 4, we get

1/4

So, 1/4 can be written in ratio as 1:4

Therefore, the ratio equivalent to the ratio 4:16 is 1:4.

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

The total is 27, as it should be.

The area of the base of the part holding water is ...

  π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

  V = Bh

  V = (2100π cm²)h = 200·1000 cm³

  h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

__

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.
