Answer:

226.2 feet

Step-by-step explanation:

The fence around the dog's house is a circle, with a radius of 12 meters.

To calculate the distance the dog runs, we need to find the circumference of that circle, which is given by the formula:

C = 2 π r, since we know r, the calculation is easy:

C = 2  π 12 = 24 π = 75.4 feet.

The dog makes three laps around the circle before calming down... so he runs 3 times 75.4 feet.

Dogs run = 3 x 75.4 ft = 226.2 feet

The answer is:

Matt will need 120 quilt squares.

To solve the problem, we need to calculate the area of the wall and then, calculate how many quilt squares are needed.

We know that the wall measures 1 yard and 2 1/2 feet, also we know that the quilt squares measures 3 inches.

First, we need to conver the units:

So, converting we have that:

[tex]1yard=36inches[/tex]

Also,

[tex]1feet=12inches[/tex]

[tex]2.5*1feet=2.5*12inches[/tex]

[tex]2.5feet=30inches[/tex]

For the wall:

Calculating the area of the wall, we have:

[tex]Area_{rectangle}=base*height\\\\Area_{rectangle}=36inch*30inch=1080inch^{2}[/tex]

For the quilt squares:

Calculating the area of the quilt square, we have:

[tex]Area_{square}=side*side\\\\Area_{square}=3inch*3inch=9inch^{2}[/tex]

Therefore, to calculate how many quilt squares are needed, we need to use the following equation:

[tex]QuitSquaresNeeded=\frac{Area_{rectangle}}{Area_{square}}\\\\QuitSquaresNeeded=\frac{1080inch^{2}}{9inch^{2}}=120[/tex]

Hence, we have that Matt will need 120 quilt squares.

Have a nice day!

Answer:

2. A. H-red, H-blue, H-green, H-yellow, T-yellow, T-green, T-blue, T-red

3. 18

Step-by-step explanation:

2. Flipping a coin and spinning a 4-color spinner.

There are two possible outcomes for the coin: heads or tails (H or T).

There are still 4 possibilities for the spinner: red, blue, green and yellow

Since both are independent, you multiply the possible outcomes of each event, so 2 * 4 = 8 possible outcomes.

To list them all, take each possible outcome on one item (coin or spinner), and match it with all the possible outcomes of the other item.

So answer is  A. H-red, H-blue, H-green, H-yellow, T-yellow, T-green, T-blue, T-red

3. Lunch combinations

You have 2 sandwiches, 3 sides and 3 beverages. How many different lunches can you make picking one of each?

As in the problem above, these possible outcomes are independent (choosing one specific sandwich has no impact on the side or the beverage).

So, to count all the possible outcomes, you just have to multiply the possible outcomes of each item, so

L = 2 sandwiches x 3 sides x 3 beverages = 18 possible lunches

Answer:69.38

Step-by-step explanation: Sue = 15.5 allie = 23.25 carol = 15.5+32.25 - 8.12 2.   15.5+32.25=38.75-8.12=  30.63 now all together 23.25+15.5+30.63= 69.38

The girls danced for a total of 30 minutes and 33 seconds.

First, we need to calculate the total time Sue and Allie danced combined:

Sue danced for 15.5 minutes, which can be written as [tex]\(\frac{155}{10}\)[/tex] minutes.

Allie danced for 23.25 minutes, which can be written as [tex]\(\frac{2325}{100}\)[/tex] minutes.

To combine these times, we need a common denominator, which is 100:

Sue's time in minutes: [tex]\(\frac{155 \times 10}{100} = \frac{1550}{100}\)[/tex]

Allie's time in minutes: [tex]\(\frac{2325}{100}\)[/tex]

Now we add Sue's and Allie's times:

[tex]\(\frac{1550}{100} + \frac{2325}{100} = \frac{3875}{100}\)[/tex]

Converting this back to mixed numbers:

[tex]\(\frac{3875}{100} = 38\)[/tex] minutes and [tex]\(\frac{75}{100}\)[/tex] minutes, which is 45 seconds.

Now, Carol danced for 8 minutes and 12 seconds less than the combined time of Sue and Allie. We need to subtract this time from the total time Sue and Allie danced:

[tex]\(38\)[/tex] minutes and [tex]\(45\)[/tex] seconds [tex]\(-\) \(8\)[/tex] minutes and [tex]\(12\)[/tex] seconds.

Subtracting the minutes:

[tex]\(38 - 8 = 30\)[/tex] minutes.

Subtracting the seconds:

[tex]\(45 - 12 = 33\)[/tex] seconds.

Therefore, Carol danced for 30 minutes and 33 seconds. Since Sue and Allie's combined time was 38 minutes and 45 seconds, and Carol danced for 8 minutes and 12 seconds less, the total time the girls danced altogether is:

[tex]\(38\)[/tex] minutes and [tex]\(45\)[/tex] seconds [tex]\(-\) \(8\)[/tex] minutes and [tex]\(12\)[/tex] seconds [tex]\(=\) \(30\)[/tex] minutes and [tex]\(33\)[/tex] seconds.

Thus, the girls danced for a total of 30 minutes and 33 seconds.

D) Arc wx and arc yz is the correct answer because both arcs are equal to 27

Answer:

Option D is correct.

Step-by-step explanation:

Arcs are said to be equal if it subtends equal angles at the center

here we can see that  arcs WX and ZY subtends equal angle and its measure is 27 degrees.

therefore option D is correct answer

Since we are not given the angles subtended by WY and XZ in the center

so we cannot say for option A

Likewise we cannot say  for rest of the option.

Answer:

They will each have painted 8 km. This goal will be met on Day 4.

Step-by-step explanation:

Group A | Group B

Start: 2   | Start: 5                               Day 1

2 + 2 = 4 | 5 + 1 = 6                            Day 2

4 + 2 = 6 | 6 + 1 = 7                             Day 3

6 + 2 = 8 | 7 + 1 = 8                            Day 4

The first group and second group of workers will each have painted 8 kilometers of the bridge after 3 days.

This question is related to the concept of linear equation in one variable. To solve such a problem, we typically set up an equation that relates the two groups and the amount they have painted to find out when they have painted an equal amount.

The equation representing the painting work of the first group is: 2 + 2d = x, where d is the number of days and x is the total distance painted. For the second group, the equation is 5 + d = x. We can set up these equations because each new day adds certain kilometers to the existing painted distance.

To find when these two equations are equal, we can simply equate them: 2 + 2d = 5 + d. Solving this equation, we get d = 3 days. Substituting d = 3 into either of the group's equations, we get x = 8 kilometers.

So, after 3 days, both groups would have painted 8 kilometers each.

Answer:

The sides of the new triangle compared to the original are 4 times smaller.

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z-----> the scale factor

x----> the corresponding side of new triangle

y----> the corresponding side of the original triangle

[tex]z=\frac{x}{y}[/tex]

we have

[tex]z=\frac{1}{4}[/tex]

substitute

[tex]\frac{1}{4}=\frac{x}{y}[/tex]

[tex]x=\frac{1}{4}y[/tex]

therefore

The sides of the new triangle compared to the original are 4 times smaller.

Answer:

Step-by-step explanation:

It is not possible to fill a smaller rectangular prism with larger 14-inch cubes.

Hence, it is impossible to fill the rectangular prism with cubes of 14-inch edge lengths.

Answer:

#4

Step-by-step explanation:

1) The y intercept is 0.

2) Convert to slope-intercept form:

2x + 3y = 12

3y = -2x + 12

y = -2/3 x + 4

So the y-intercept is 4.

3) Write in point-slope form:

y + 4 = 2 (x - 1)

Now convert to slope-intercept form:

y + 4 = 2x - 2

y = 2x - 6

So the y-intercept is -6.

4) The y-intercept is 5.

So of the four lines, #4 has the largest y-intercept.

Answer:

[tex]\boxed{\text{(4) The graph}}[/tex]

Step-by-step explanation:

The question is asking, which function has the greatest value when x = 0?

We must evaluate f(0) for each one.

(1) ƒ(x) = 3x

f(0) = 3 × 0 = 0

(2) 2x + 3y = 12

        Let x = 0.

2 × 0 + 3y = 12

     0 + 3y = 12

           3y = 12

            y = 4

(3) The line

The line has a slope of 2, and y= -4 when x = 1.

y increases by 2 when x increases by 1.

For the same reason, y decreases by 2 when x decreases by 1.

Thus, when x decreases from 1 to 0, y decreases from -4 to -6.

f(0) = -6.

(4) The graph

The graph has a y-intercept at y = 5, so,

f(0) = 5.

[tex]\boxed{\textbf{The graph}}[/tex] has the greatest y-intercept.

Answer:

The probability that the point will be in the part that is NOT shaded is about 20% ⇒ 4th answer

Step-by-step explanation:

* Lets look to the figure

- There are four circles inscribed in  a square

- The four circles touched each other and touched the four

  sides of the square

∴ The side of the square = twice the diameter of a circle

- If the side of the square is l and the diameter of the circle is d

∴ l = 2d ⇒ divide the two sides by 2

∴ d = (1/2) l

∵ The radius of the circle = (1/2) the diameter

∴ r = (1/2) d

∵ d = (1/2) l

∴ r = (1/2)(1/2) l = (1/4) l

* Now lets find the area that NOT shaded

∵ The area of the square = side × side

∴ The area of the square = l × l = l²

∵ The area of the circle = πr²

∵ r = (1/4) l

∴ r² = [(1/4) l]² = (1/4)² × l² = (1/16) l²

∴ The area of one circle = (1/16)πl²

- The shaded part is the four circles

∴ The shaded area = 4 × (1/16)πl² = (1/4)πl²

- The part is not shaded = Area of the square - Area of the shaded part

∴ The area of not shaded = l² - (1/4)πl² ⇒ take l² as a common factor

∴ The area of not shaded = l²(1 -1/4 π)

- The probability that the point will be in the part that not shaded is

  area of the part not shaded/area of the square

∴ P = l²(1 - 1/4 π)/l² ⇒ cancel l² from up and down

∴ P = (1 - 1/4 π )/1 = 0.2146 ≅ 0.2

- Chang it to percent number

∴ P = 0.2 × 100% = 20%

* The probability that the point will be in the part that is NOT shaded

  is about 20%

∴ r = (1/2) d

∴

To solve the problem, we need to perform the operations and then, add like terms.

We need to apply the distributive property, which is defined by the following way:

[tex]a(b+c)=ab+ac[/tex]

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

[tex]3x+5x+x^{2}=8x+x^{2}[/tex]

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.

So, we are given the expression:

[tex]-2(2x+5)-3(x-1)[/tex]

Then, solving we have:

[tex]-2(2x+5)-3(x-1)=-4x-10-(3x-3)\\\\-4x-10-(3x-3)=-4x-10-3x+3\\\\-4x-10-3x+3=-4x-3x-10+3\\\\-4x-3x-10+3=-7x-7[/tex]

Hence, we have that the answer is:

[tex]-2(2x+5)-3(x-1)=-7x-7\\[/tex]
