aivan3 [116]3 years ago
8 0

Answer:

40

Step-by-step explanation:

Using the method of prime factors

8 = 2 × 2 × 2 = 2³

2 = 2

5 = 5

Then LCM = 2³ × 5 = 8 × 5 = 40

Answer:

40

Step-by-step explanation:

The goal of LCM is to get the least common number that can divide any of the numbers given without turning them into fractions until all of them are divided to 1.

The least number that can divide any of the numbers is 2, dividing through we remain with 8/2=4, 2/2=1, and 5. Notice how the 5 remains the same, since dividing it by 2 will turn it into a fraction

Divide through by 2 again, we get 4/2=2, 1, and 5

Divide through by 2 yet again, we get 2/2=1, 1, and 5

Divide through by 5, we get 1, 1, and 1

The LCM is now multiplications of all the least numbers used above= 2*2*2*5=40

If the polygon is translated 4 units down and 5 units right, what will the coordinates of the new image be? Use prime notation i
steposvetlana [31]

Using prime notation, the new coordinates after translation are;

<em>New coordinates;</em>

A': (-1, 1)

B': (-1, -2)  

C': (3, -2)

D': (3, 2)

  • From the attached image, we can see that the coordinates are;

A(-6, 5)

B(-6, 2)

C(-2, 2)

D(-2, 6)

  • Translating the polygon down by x units means the value of the y-coordinates will reduce by 4.
  • In a similar fashion, translation 5 units to the right means that the x-coordinates would increase by 5.

  • Applying these translation numbers to our coordinates, we will now have;

        A(-6 + 5, 5 - 4)

        B(-6 + 5, 2 - 4)

        C(-2 + 5, 2 - 4)

        D(-2 + 5, 6 - 4)

Simplifying each of them gives us the new coordinates as;

A: (-1, 1)

B: (-1, -2)  

C: (3, -2)

D: (3, 2)

What is the approximate value of q in the equation below?
gayaneshka [121]

<u>Given</u>:

The given equation is q+\log _{2}(6)=2 q+2

We need to determine the approximate value of q.

<u>Value of q:</u>

To determine the value of q, let us solve the equation for q.

Hence, Subtracting \log _{2}(6) on both sides of the equation, we get;

q=2 q+2-\log _{2}(6)

Subtracting both sides of the equation by 2q, we have;

-q=2-\log _{2}(6)

Dividing both sides of the equation by -1, we have;

q=\log _{2}(6)-2

Now, substituting the value of log_2(6)=2.585, we have;

q=2.585-2

Subtracting the values, we get;

q=0.585

Thus, the approximate value of q is 0.585

Hence, Option C is the correct answer.
