Answer:

81 is the LCM of 81 and 3

Step-by-step explanation:

81 is the smallest (least) number that both (common) 81 and 3 "go into" (multiple)

81 goes into 81.

3 goes into 81.

81 is the smallest number that they both go into.

Hi there,

please see below for solution steps :

________

<u></u>\ast<u> Key moment to solving this problem</u> :

  • the LCM stands for least common multiple

Okay. Now, what is the lcm of 3 and 81?

One way to find the lcm is : list several multiples of each number.

However, it's not a really efficient way, because listing all the multiples of 3 until we get to 81 is time-consuming!

So we can ask ourselves one question : <em>Is 81 divisible by 3?</em>

Sure! with this in mind, let's ask ourselves another question : <em>what is the lcm of 81 and 3?</em>

The answer to that is \boldsymbol{81}.

Hope the answer - and explanation - made sense to you,

happy studying !!                                                                 \bold{Frozen \ melody}

To make a box and whisker plot, first you write down all of the numbers from least to greatest.

0, 1, 3, 4, 7, 8, 10

The median is 4, so that’s the middle line of the plot.

So now we have:
0, 1, 3, [4,] 7, 8, 10

So next we have to find the 1st and 3rd interquartiles..
0, [1,] 3, [4,] 7, [8,] 10

Those are the next 2 points you put on the plot.

Lastly, the upper and lower extremes. These are the highest and lowest numbers in the data.
[0,] 1, 3, 4, 7, 8, [10]

These are the final points on the plot.

To make the box of a box-and-whisker plot, you plot the 3 Medians of the data: 1, 4, and 8, and connect those to make a box that has a line in the middle at 4.

Next, you plot the upper and lower extremes: 0 and 10, by making “whiskers” that connect to the box. So you draw a line from the extremes to the box.

Answer: The ladder is 5.3 m long
Step by step solution
1. Draw out the scenario, ie a right triangle where the hypotenuse is the ladder, the wall is 4.5m and the angle the ladder and the ground makes 58 degree.

2. Soh, Cah, Toa
The wall is opposite, the ground is adjacent, and the ladder is hypotenuse
Sine (58) = 4.5/h

3. Solve for hypotenuse
h * sine (58) = 4.5
h = 4.5/sine (58)
h = ~ 5.3 m

The ratio of red tacks to blue tacks on the bulletin board is 3 to 5. There are 50 blue tacks. How many red tacks are there?
bazaltina [42]

Answer:

If we want our ratio to stay the same (3 to 5), we'll need to pair a set of 3 blue tacks with every set of 5 red tacks. In a group of 50, we can make 10 groups of 5 red tacks, so we'll also need 10 groups of 3 blue tacks, which gives us a total of 30 blue tacks
