Mr. Stewart gives his students 3 straws that measure 10 inches, 12 inches and 18 inches. Ryan says that there is only one unique way to arrange the straws to form a triangle. Marcy says there are many ways to arrange the straws to form a triangle. Which student is correct? Explain.

Answer:

x≤3.6

Step-by-step explanation:

First, lets simplify the equation:

5x+3≤21

5x≤18

x≤18/5

x≤3.6

To draw this on the number line, draw a filled in circle 6/10 to the right of 3 and 4/10 to the left of 4. Then draw an arrow pointing to the left.

I hope this solution was useful. Happy mathing!

Answer:

[tex]x \leq \frac{18}{5}[/tex], (Please see attachment)

Answer: 1620 in.^3

Step-by-step explanation: Basically, you have a prism that has a base of 180, and a height of 9 in. The volume of a rectangular prism is length*width*height, and 180 is the length*width, so to find the answer, you do 180*9, which is equal to 1620.

Answer:

D

Step-by-step explanation:

I have this fancy calculator that can graph stuff… so I put it in my calculator, and compared the graph… y axis in graph 1 was +2 and y axis in graph 2 is -2

Also the graph in function 2 is steeper as it is going from 2 to 2

Answer:

The answer is 211.96

Step-by-step explanation:

First I did the semicircle, the radius is 7 so 7 x 2 = 14 and then I did

14 x 3.14 = 43.96

Then I did 12 x 14 = 168

Finally 168 + 43.96 = 211.96

Answer:

a) 317 units^3

Step-by-step explanation:

Answer:

(8x-10)/2

Step-by-step explanation:

1. A straight line between two points represents a line segment.

2. (Video is not provided with the question)

3. You will need 2 points to start a line. (1 point is a ray)

Explanation:

Let's go over an example.

We'll have a = 1 and b = 7 which makes a < b true. Feel free to pick your own favorite pair of numbers such that b is larger than 'a'.

The corresponding opposites are:  -a = -1 and -b = -7

The relationship flips because the opposites of each number are flipped. So instead of saying -a < -b, we have -a > -b

Sure enough, -1 > -7 is a true statement. Use a number line to see this. I recommend a vertical number line.

In short, going from a < b to -a > -b means we flip the signs of each term, and we flip the inequality sign as well.

Answer:

It's the last one (-3m^-3n)

Step-by-step explanation: You can take this equation and divide it up into parts. To make this simple, make it...

-9/3 × m/m^4 × n²/n

m/m^4 is basically [tex]m^{1-4}[/tex], which ends up being m^-3.

n²/n is basically [tex]n^{2-1}[/tex] which ends up being n^1, or just n.

Then simplify all parts of the equation so you are left with:

-3 × m^-3 × n

You are then left with the bottom answer.

Answer: 13 cm^3

Step-by-step explanation:

The volume of a rectangular prism is the height*width*length.

3 1/4 as a decimal is 3.25.

Now we can plug in the given values into the formula for the volume.

Therefore, the volume = 3.25 cm * 4 cm * 1 cm

= 13 cm^3

Answer:

the anwser is 16 1/4 cm

Answer:0!

Step-by-step explanation:

Answer: 180

Step-by-step explanation:

Since they're a bunch of signs I would use PEMDAS

P = parentheses

E = Exponent

M = multiplication or D = Division  

A = Addition or S = Subtraction  

Problem:

42 x 8 – 236 + 50 x 2 – 20

Note: for example if you're up to multiplication OR division that means whatever you see first here's an example

66 x 4 ÷ 28

You see multiplication first so use it if it's the other way around use division first. THE SAME GOES WITH ADDITION AND SUBTRACTION!!!!
