I’m trying to understand what it’s asking not sure if this is correct or not

Artemon [7]

Answer:

Step-by-step explanation:

First of all, the term multiple needs to be defined.

When a number is multiplied by another number other then zero, we get the multiple as result.

i.e. Multiples of 2 are: 2, 4, 6, 8, 10

To find the Least Common Multiple of numbers, we list the multiples of those numbers and then the samllest factor that is common in both lists is chosen as least common multiple.

1. 10, 20

Multiples of 10: 10, 20, 30, 40, 50, 60, 70, 80

Multiples of 20: 20, 40, 60, 80, 100

Least Common Multiple: 20

2. 3, 9

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27

Multiples of 9: 9, 18, 27, 36, 45

Least Common Multiple: 9

3. 12, 24

Multiples of 12: 12, 24, 36, 48, 60, 72

Multiples of 24: 24, 48, 72, 96

Least Common Multiple: 24

4. 25, 45

Multiples of 25: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250

Multiples of 45: 45, 90, 135, 180, 225, 270, 315

Least Common Multiple: 225

5. 5, 10

Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40

Multiples of 10: 10, 20, 30, 40, 50, 60

Least Common Multiple: 10

6. 49, 56

Multiples of 49: 49, 98,147, 196, 245, 294, 343, 392, 441

Multiples of 56: 56, 112, 168, 224, 280, 336, 392, 448

Least Common Multiple: 392

This method of finding LCM is brute force and requires more time.

Another method is by using GCD(Greatest Common Divisor). It is the greatest positive integer number which completely divides all the numbers in consideration.

The product of the numbers is divided by their GCD to find the LCM.

i.e. for Q6

GCF(49, 56) = 7

LCM(49,56)= (49*56)/7

=2744/7=392

the perimeter of a triangle z measures 48 cm . it was dilated with a scale factor of 0.8 to form triangle p . what is the perime

Aliun [14]

Answer:

The perimeter of the p triangle = 38.4 cm

Step-by-step explanation:

Given

The perimeter of a triangle z be = 48 cm

The triangle is dilated by a scale factor of 0.8

To determine

What is the perimeter of the triangle after it is dilated by a scale factor of 0.8?

As the scale factor < 1, it means the new perimeter will be reduced.

The new perimeter of the triangle p can be calculated by multiplying the perimeter of the original triangle z by 0.8

i.e.

Perimeter of triangle p = 48 × 0.8 = 38.4 cm

Therefore, the perimeter of the triangle p is = 38.4 cm

A jogger running at 9 kmph alongside a railway track in 240 metres ahead of the engine of a 120 metres long train running at 45

sasho [114]

The speed is the distance covered by an object at a particular time. The time it will take for the train to pass the jogger is 36 seconds.

<h3>What is speed?</h3>

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

$\rm{Speed = \dfrac{Distance}{Time}$

The speed of the train and the man can be written as,

Speed of the train = 45kmph = 45×(5/18) = 12.5mps
Speed of the man = 9kmph = 9×(5/18) = 2.5mps

Now, the time it will take for the train to completely pass the man is,

Relative speed = Distance / Time

(12.5 - 2.5) = (240 + 120)/ Time

10 = 360/Time

Time = 360/10

Time = 36 seconds

Hence, the time it will take for the train to pass the jogger is 36 seconds.
