There are 126 possible selections of collars for Tony's 4 dogs if repetitions of colors are not allowed.

The number of selections of collars possible if repetitions of colors are not allowed, we can use the concept of permutations.

Using the formula for permutations without repetition, we can calculate this as:

9P4 = 9! / (9 - 4)!

= 9! / 5!

= (9 * 8 * 7 * 6) / (4 * 3 * 2 * 1)

= 3024 / 24

= 126

This shows that  126 possible selections of collars for Tony's 4 dogs if repetitions of colors are not allowed.

Answer: In  1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat

Step-by-step explanation:

Since we have given that

Rabbit's heart beat in 1 min 212 times more than dog's heart beat in 1 min.

So, in 1 hour , we get,

[tex]1\text{ hour }= 60\text{ minutes}\\so, heartbeat = 212\times 60=12720[/tex]

So, in  1 hour, 12720 more times rabbit's heart beat than a dog's rabbits heart beat .

To determine how many more times a rabbit's heart beats than a dog's in an hour, multiply the rabbit's beats per minute by 60 to get the hourly beat total, and do the same for the dog. Subtract the dog's total from the rabbit's to find the difference. Assuming a dog's heart rate of 70 beats per minute, a rabbit's heart beats 8,520 more times per hour than a dog's.

To calculate how many more times a rabbit's heart beats than a dog's in one hour, we first need to establish the number of beats per hour for both animals. Since the rabbit's heart beat is 212 times per minute, we multiply this number by 60 (the number of minutes in an hour) to find out the total heartbeats in one hour for a rabbit:

Rabbit heartbeats per hour = 212 beats per minute x 60 minutes = 12720 beats per hour.

Next, we need the same figure for the dog. Without the specific heart rate for the dog, we'll assume a generic heart rate for calculation purposes. For example, if a dog's heart beats 70 times per minute (a common rate for dogs), we multiply by 60:

Dog heartbeats per hour = 70 beats per minute x 60 minutes = 4200 beats per hour.

Now, to find out how many more times the rabbit's heart beats than the dog's, we subtract the dog's heartbeats per hour from the rabbit's:

Rabbit's additional heartbeats = 12720 beats per hour - 4200 beats per hour = 8520 more beats per hour.

Let’s start out by what we already know. He used 2/5 of flour to make bread and he used 16 Ibs to make bread. This implies that the amount is (2/5)x=16.

Answer:

13.5 kgs.

Step-by-step explanation:

Here we have to find conversion factor of lbs into kg.

For this we use the given information.

Given that the weight of a dog is 20 lbs and also 9 kg.

Hence we have conversion factor as

20 lbs = 9 kg

Or 1 lb =9/20 = 0.45 kg.

Using this, we find the 30 lb converted into kg.

For 1 lb, equivalent kg = 0.45

Hence for 30 lbs equivalent kg= 30(0.45) = 13.5 kg.

Answer: 36 degrees

Step-by-step explanation:

subtract 5 from 30=25

add 11 to 25

25+11=36

Considering the temperature changes throughout the day, the temperature at noon was 36 degrees F.

If the temperature started at 30 degrees F at midnight, and it dropped 5 degrees by 6:00 a.m, the temperature at 6:00 a.m. was 30 - 5 = 25 degrees F. Then, if the temperature increased by 11 degrees F by noon, we just add this increase to the temperature at 6:00 a.m. This results in 25 + 11 = 36 degrees F. So, the temperature at noon was 36 degrees F.

[tex]\frac{7}{9} -\frac{2}{8} \times \frac{4}{9}[/tex]

Start by multiplying the fractions together. When multiplying fractions they don't need to have a common denominator, so multiply 2/8 and 4/9 from left to right.

[tex]\frac{2}{8} \times \frac{4}{9} = \frac{8}{72}[/tex]

Now your new problem looks like: 7/9 - 8/72. When subtracting fractions they have to have common denominators so multiply 7/9 by 8/8.

[tex]\frac{7}{9} \times \frac{8}{8}= \frac{56}{72}[/tex]

You can now subtract 56/72 and 8/72 to get your final answer.

[tex]\frac{56}{72} -\frac{8}{72} = \frac{48}{72}[/tex]

This fraction can be simplified by dividing both sides by 8 because the numerator and denominator of this fraction are multiples of 8 and can be divided evenly by 8.

[tex]\frac{48}{72} \div \frac{8}{8} = \frac{6}{9}[/tex]

6/9 can be simplified even further by dividing both sides by 3 because both 6 and 9 can be divided evenly by 3.

135 is a composite number.

135 = 1 x 135, 3 x 45, 5 x 27, or 9 x 15.

Factors of 135: 1, 3, 5, 9, 15, 27, 45, 135.

Prime factorization: 135 = 3 x 3 x 3 x 5, which can also be written 135 = 3³ x 5

The prime factorization of 135 is 3^3 × 5.

The prime factorization of 135 is obtained by finding the prime numbers that divide 135 evenly, repeatedly dividing until the quotient is no longer divisible by any prime numbers.

Starting with the number 135, we can see that it is divisible by 3, so we divide 135 by 3:

135 ÷ 3 = 45

Now, we repeat the process with 45. It is also divisible by 3:

45 ÷ 3 = 15

Continuing, we divide 15 by 3:

15 ÷ 3 = 5

Now we have reached a quotient of 5, which is a prime number. We cannot divide it any further, so we have obtained the prime factorization of 135 as follows:

135 = 3 × 3 × 3 × 5

Therefore, the prime factorization of 135 is 3³ × 5.

Answer:

A rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.

Step-by-step explanation:

We are told that a ceiling fan has 5 equally spaced blades. It will work as a regular pentagon.

We can find angle of rotation to map one blade on adjacent blade dividing 360 by 5 as sum of angles of regular pentagon equals to 360 degrees.

[tex]\text{ Angle of rotation}=\frac{360}{5}[/tex]

Upon dividing 360 by 5 we will get,

[tex]\frac{360}{5} =72[/tex]

Therefore, a rotation of 72 degrees will map one blade of ceiling fan to its adjacent blade.    

The angle between adjacent blades in a five-blade ceiling fan is b. 72°.

**Understanding the Situation**:

We have a ceiling fan with five equally spaced blades. We need to find the angle of rotation that maps one blade onto the adjacent blade.

**Identifying the Angle between Blades**: Since the blades are equally spaced, we can find the angle between adjacent blades by dividing the full circle (360°) by the number of blades, which is 5.

  [tex]\[ \text{Angle between adjacent blades} = \frac{360°}{5} = 72° \][/tex]

**Checking the Options**:

  - (a) 144° is twice the angle between adjacent blades. This would correspond to skipping one blade and landing on the third blade, which is not adjacent.

  - (b) 72° is the same as the angle between adjacent blades. This seems promising.

  - (c) 90° is not consistent with the division of the circle by the number of blades.

  - (d) 36° is half the angle between adjacent blades. This would correspond to a situation where we skip two blades, which is not adjacent.

235$ and if you withdraw 20$ on three days thats 60$ so if we remove that from the account we have 175$ left.

Then on Friday when he got paid he put 130$ into the bank he has 175+130=305$

If he wrote a check 1 for 167$ and 1 for 212$ thats his account balance - 212 then -167 = 305 -378 so he has a balance of -73

The checking balance after writing the checks is -$74.

To calculate the checking balance after writing the checks, we need to keep track of George's transactions:

To find the final balance, we add the positive values (deposits) and subtract the negative values (withdrawals and checks):

Starting balance ($235) + Deposits ($130) - Withdrawals ($60) - Checks ($167 + $212) = $235 + $130 - $60 - $167 - $212 = -$74

Therefore, the checking balance after writing the checks is -$74.

Solution-

Quadratic regression equation,

[tex]y =ax^2+bx+c[/tex]

taking x = input/independent variable = year - 2000

and y = output/dependent variable = share of the global GDP

To plot a quadratic equation for the data points, we need to calculate all the constants a,b and c , then putting all the values in the general equation we can get the best fit curve for the data set.

Using, the graphing calculator, we can calculate the values of a, b, and c. The values were found to be,

a = -0.0471

b = 2.6366

c = 12.1001

Putting all the values,

[tex]y =-0.0471x^2+2.6366x+12.1001[/tex]

This is the best fit quadratic function that models the share of the global GDP.

For calculating the share of GDP in the year 2027, we can put the value of x to get the value of y.

x = year-2000=2027-2000=27,

[tex]y=-0.0471(27)^2+2.6366(27)+12.1001=-0.0471(729)+2.6366(27)+12.1001=48.95[/tex]

∴ In the year 2027, the maximum share will be 48.95% of total GDP.

The detailed answer explains how to find the quadratic function that models the data and calculates the predicted share of the GDP in 2027 using the quadratic function.

Quadratic Function Model:

Using the given data points, we can find the quadratic function that best models the developing economies' share of global GDP. This can be achieved by fitting a quadratic equation to the data.

The quadratic function that best models the data is: y(x) = 0.7386x^2 - 28.4235x + 276.0976

Predicted Share of GDP in 2027:

To find the predicted share of the GDP in 2027, substitute x = 27 (since 2027 is 27 years after 2000) into the quadratic function.

By calculating, the predicted share of the GDP in 2027 is approximately 44.5233%.

To break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.

The break-even point occurs when the total cost is equal to the total revenue.

We can find this point by setting the cost equation and the revenue equation equal to each other and solving for x :

Set the cost and revenue equations equal :

  Given that the cost equation is y = 1,800 + 400x, and the revenue equation is y = 600x , set these two equations equal to find the break-even point:

[tex]\[ 1,800 + 400x = 600x. \][/tex]

Rearrange the equation :

  Subtract 400x from each side:

 [tex]\[ 1,800 = 200x. \][/tex]

Solve for x :

  Divide by 200 to isolate x :

 [tex]\[ x = \frac{1,800}{200} = 9. \][/tex]

Therefore, to break-even, John Thunderhawk must sell 9 cabinets. After selling 9 cabinets, his revenue will start exceeding his costs, allowing him to make a profit.

Question :

John Thunderhawk is making furniture. He finds that to design a particular cabinet and set up his shop to produce it costs $1,800. Then the labor and supplies to build each one are $400. So his cost, y, for x items is represented by y=1,800 + 400x. He can sell the cabinets for $600. So his revenue, y, is represented by y=600x. The solution to this system of equations is his break-even point, the point beyond which he starts making a profit. How many cabinets must he sell to break-even?

Answer:

41.99 or 42.0 volts.

Step-by-step explanation:

We have been given the impedance (Z) of the circuit which is:

[tex]Z=3.342+4.176i[/tex]

and the current through the circuit is:

[tex](5.772-5.323i)[/tex]

The voltage across the circuit is given by:

[tex]V= I\times Z=IZ[/tex], where 'V' is the voltage, 'I' is the current, and 'Z' is the impedance.

Plugging the values of 'I' and 'Z' we get:

[tex]V=(5.772-5.323i)\times 10^{-3}\times (3.342+4.176i)\times 10^3[/tex]

[tex]V=(5.772-5.323i)\times(3.342+4.176i)[/tex]

[tex]V= (41.51+6.31i)[/tex]

Now that we have the voltage, we can find the magnitude of the voltage as follows:

[tex]V= \sqrt{(41.51)^2+(6.31)^2}=\sqrt{1723.08+39.81}=\sqrt{1762.89}=41.98 \approx 42.0[/tex]

So the magnitude of the voltage across the circuit is 42.0 Volts.

The only number between 590 and 610 that is divisible by 2, 3, 5, and 10 is 600.

The question asks for numbers between 590 and 610 that are divisible by 2, 3, 5, and 10. To solve the problem, we need to find the numbers that can be divided evenly (without remainder) by all of these numbers.

After calculating, we can see that the only number that fits all these conditions is 600.

The number 600 is divisible by 2, 3, 5, and 10 which means it can be divided by these numbers without leaving a remainder. For example, 600 divided by 2 equals  '300', 600 divided by 3 equals '200', 600 divided by 5 equals '120', and 600 divided by 10 equals '60'.
