It is found that Ken will have run 3 laps and Hamid will have run 4  around a track.

Factorization is expressing a mathematical quantity in terms of multiples of smaller units of similar quantities.  Prime factorization is when all those factors are prime numbers.Thus, prime factorization expresses an integer in terms of multiples of prime numbers.

Prime factorization is unique for each integer.

To determine the number of seconds that will have passed when they meet again.  We will use the LCM, or least common multiple, for this.

Thus the prime factorization of each number:

80 = 10(8)

10 = 5(2)

8 = 2(4)

4 = 2(2)

80 = 2(2)(2)(5)(2)

60 = 10(6)

10 = 5(2)

6 = 2(3)

60 = 2(2)(3)(5)

For the LCM,

2(2)(5)(2)(2)(3) = 240

This means every 240 sec; they will both be at the start line.

Since Ken completes a lap in 80 seconds, then he will completes

240/80 = 3 laps in 240 seconds.

Since Hamid completes a lap in 60 seconds, then he will completes 240/60 = 4 laps in 240 seconds.

Hence, It is found that Ken will have run 3 laps and Hamid will have run 4.

the following expression i.e. (1.8x10⁹) (6.7 x 10¹²) in Scientific Notation is 120.6×[tex]10^{20}[/tex] and a=120.6 and b=20

Scientific notation:

Scientific notation is a method of presenting very large or very small numbers in a more simplified format. We know that whole numbers can be extended indefinitely, but such large numbers cannot be written on a piece of paper. Furthermore, the numbers found after the decimal point needed to be represented in a more straightforward manner.

(1.8x10⁹) (6.7 x 10¹²) = 120.6×[tex]10^{20}[/tex]

Given (1.8x10⁹) (6.7 x 10¹²) =a x [tex]10^{b}[/tex]

a x [tex]10^{b}[/tex]= 120.6×[tex]10^{20}[/tex]

a=120.6 and b=20

Therefore,the following expression i.e. (1.8x10⁹) (6.7 x 10¹²) in Scientific Notation is 120.6×[tex]10^{20}[/tex] and a=120.6 and b=20

The distance AD is 49 miles.

As per the given values of speed and time, we will calculate the distance AC. Firstly equalising the units.

As per the known fact, 60 minutes = 1 hour

30 minutes = (1/60)×30

30 minutes = 0.5 hour

Now, speed, distance and time are related as -

Speed = distance ÷ time

Distance = speed × time

Distance = 62 × 0.5

Distance = 31 miles

So, AC = 31 miles and BC = 25 miles.

Therefore, AB = AC - BC

AB = 31 - 25

AB = 6 miles

The distance AD = AC + CD

AD = 31 + 3 × AB

AD = 31 + 3 × 6

AD = 31 + 18

AD = 49 miles

Therefore, the distance between AD is 49 miles.

In the plane, there is exactly one perpendicular line to a line from a particular point.

We can see CD is marked as perpendicular segment and there are no more such possible segments.

Correct choice is B.

Answer:

b) Segment CD only

Step-by-step explanation:

Now we have to,

→ find the segment perpendicular to AB.

The segment will be,

→ CD (only)

* As it is 90° from the segment AB, we can say that it is perpendicular to AB.

Hence, option (b) is correct answer.

The possible dimensions of the rectangle having a perimeter 10 are

1)length= 4 and bredth= 1

2)length= 3 and bredth= 2

The perimeter of rectangle=2( length of rectangle + breadth of rectangle)

Given that the perimeter of rectangle=10

10=2( length of rectangle + breadth of rectangle)

5=length of rectangle + breadth of rectangle

For a rectangle, length must be always greater than the breadth

The possible values of length of rectangle= 4 and 3

As a result,the Breadth of the rectangle will be 1 if length =4

As a result,the Breadth of rectangle will be 3 if length =2

Therefore, The possible dimensions of the rectangle having a perimeter 10 are

1)length= 4 and bredth= 1

The time plane will take to travel 1050 miles into the wind is 2.5 hours.

Speed is defined as the rate of change of position in unit time.

Mathematically,

Speed = Distance/Time

Now given that,

Speed of airplane in still air = 450 mph

Speed of wind = 30 mph

Distance to travel = 1050 miles

So, Actual speed of wind = 450 mph - 30 mph

⇒ Actual speed of wind = 420 mph

So, since Speed = Distance/Time

⇒ Time = Distance/Speed

⇒ Time = 1050/420

⇒ Time = 2.5 hours

Thus, the time plane will take to travel 1050 miles into the wind is 2.5 hours.

Answer:26 eggs

Step-by-step explanation: yes

The market woman bought 60 eggs.

The market woman bought n eggs at the rate of 12 eggs for €60.

So, the cost price of each egg is given by:

Cost price per egg = €60 / 12 = €5

The total cost of n eggs is the cost price per egg multiplied by the number of eggs (n):

Total cost = €5 * n = 5n

After buying n eggs, 8 of them were broken.

So, the market woman had (n - 8) eggs left to sell.

She sold the remaining eggs at the rate of 4 eggs for €24.

The selling price of each egg is given by:

Selling price per egg = €24 / 4 = €6

The total selling price of the remaining (n - 8) eggs is the selling price per egg multiplied by the number of remaining eggs (n - 8):

Total selling price = €6 * (n - 8) = 6n - 48

The profit is the difference between the total selling price and the total cost:

Profit = Total selling price - Total cost

Since the problem states that the market woman made a profit of €12, we can set up the equation:

6n - 48 - 5n = 12

Solve for n.

Combine like terms:

n - 48 = 12

Add 48 to both sides:

n = 60

So, the market woman bought 60 eggs.

The probability that the number of heads obtained from flipping the two fair coins is the same is 35/128.

Probability:

Probability means the fraction of favorable outcome and the total number of outcomes.

So it can be written as,

Probability = Favorable outcomes / Total outcomes

Given,

The coin a is flipped three times and coin b is flipped four times.

Here we need to find the probability that the number of heads obtained from flipping the two fair coins is the same.

We know that,

There are 4 ways that the same number of heads will be obtained;

0, 1, 2, or 3 heads.

The probability of both getting 0 heads is

[tex]$\left(\frac12\right)^3{3\choose0}\left(\frac12\right)^4{4\choose0}=\frac1{128}$[/tex]

Probability of getting 1 head,

[tex]$\left(\frac12\right)^3{3\choose1}\left(\frac12\right)^4{4\choose1}=\frac{12}{128}$[/tex]

Probability of getting 2 heads is,

[tex]$\left(\frac12\right)^3{3\choose2}\left(\frac12\right)^4{4\choose2}=\frac{18}{128}$[/tex]

And the probability of getting 3 heads is,

[tex]$\left(\frac12\right)^3{3\choose3}\left(\frac12\right)^4{4\choose3}=\frac{4}{128}$[/tex]

Therefore, the probability that the number of heads obtained from flipping the two fair coins is the same is,

=> (1/128) + (12/128) + (18/128) + (4/128)

=> 35/128.
