but the others i dont know!

i remember this test, so 3 would be 3 x 3 x 3 because it has it on top w the ma so mark brainlist if correct!

LM = 9, NR = 16, SR = 8. Find the perimeter of triangle LRN.

sweet [91]

<h2>D. 50 units</h2>

Hi, I’m Lena and I will be answering your question to the best of my ability. If you have any further questions after my answer, do not hesitate to ask me! ツ

♡ Let’s look at the main important thing(s) that will lead you in the correct path.

♥ The perimeter is the outside, it is <em>around</em> the figure. When you see those inner triangles, do not pay attention to them! They are just there to make your overthink the question.

♡ Let's solve!

♥ To begin, let's take LM. It already gives you half the segment, so all you need to do is double the number. 9*2=18.

♥ Now, let's take a look at NR. They already give you the segment as a whole, so you do not need to worry about it!

♥ Look at SR. You do the same thing as you did to LM, double the number. 8*2=16.

Now, we add all the numbers to get our final answer.

18+16+16=50.

What is the slope of (8,3) and (-4,-6)?

Nonamiya [84]

<u>Answer:</u> The slope of the line formed by these two points is $\frac{3}{4}$

<u>Step-by-step explanation:</u>

To calculate the slope, we use the formula:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

For the coordinates given:

$x_1=8\\y_1=3\\x_2=-4\\y_2=-6$

Putting values in above equation, we get:

$Slope=\frac{(-6-3)}{(-4-8)}\\\\Slope=\frac{-9}{-12}\\\\Slope=\frac{3}{4}$

Hence, the slope of the line formed from these two coordinates is $\frac{3}{4}$

In the problem 83 - 10 x 5 - 4, which step should you perform first?

Ksivusya [100]

Multiplication comes before any subtraction...so do 10 x 5 first

There are only two orthodontists in a village and both wore braces until last month. Dr. Carter now has straight teeth and a cle

lana66690 [7]

Answer:

Dr Carter

Step-by-step explanation:

I would want to visit Dr. Carter for an orthodontis appointment for multiple reasons. One, he can prove that he doesn’t do his work sloppily as his office is clean, and two, he can prove that his treatments work. since his teeth are now perfectly straight, that shows that his Braces really work, whereas Dr. Shuman’s treatments either don’t work or take a lot longer for results to appear.

A university warehouse has received a shipment of 25 printers, of which 10 are laser printers and 15 are inkjet models. If 6 of

Tanya [424]

Answer:

The probability is 0.31

Step-by-step explanation:

To find the probability, we will consider the following approach. Given a particular outcome, and considering that each outcome is equally likely, we can calculate the probability by simply counting the number of ways we get the desired outcome and divide it by the total number of outcomes.

In this case, the event of interest is choosing 3 laser printers and 3 inkjets. At first, we have a total of 25 printers and we will be choosing 6 printers at random. The total number of ways in which we can choose 6 elements out of 25 is $\binom{25}{6}$ , where $\binom{n}{k} = \frac{n!}{(n-k)!k!}$ . We have that $\binom{25}{6} = 177100$

Now, we will calculate the number of ways to which we obtain the desired event. We will be choosing 3 laser printers and 3 inkjets. So the total number of ways this can happen is the multiplication of the number of ways we can choose 3 printers out of 10 (for the laser printers) times the number of ways of choosing 3 printers out of 15 (for the inkjets). So, in this case, the event can be obtained in $\binom{10}{3}\cdot \binom{15}{3} = 54600$

So the probability of having 3 laser printers and 3 inkjets is given by

$\frac{54600}{177100} = \frac{78}{253} = 0.31$
