One meter is equal to 100cm. So if you convert 2 meters into centimetres, it would be equal to 200cm. Now since you have a 200cm pipe and you want to see how many sections of 10cm you can cut, you can just divide. It’d be 200 divided by 10 which would be 20. Therefore, the pipe can be cut into 20 pieces.

Hope this helped!

Find the widest range of scores that you can get on a final exam in order to receive a grade of B for the class. Using interval
Drupady [299]

Answer:

Correct choice is B

Step-by-step explanation:

Let x% be your final test score, then the average of all test scores is

\dfrac{96+77+74+x}{4}.

Since you must have an average between 80% and 89%, then

80\le \dfrac{96+77+74+x}{4}\le 89,\\ \\320\le 247+x\le 356,\\ \\73\le x\le 109.

X is measured in percent, then the greatest value of x can be 100%. You get that

73\%\le x\le 100%.

Match the inequality to the graph of its solution.<br> a. n/4 ≤ -1<br> b. -10 ≥ -100<br> c. 5x ≥ 20
postnew [5]
<span>a. n/4 ≤ -1

Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.

That in the real number line is all the numbers to the left of - 4 (including  -4)

The matching graph is the B.


b. -10n ≥ -100

Divide both sides by - 10 => n ≤ 10

That is all the real numbers less or equal than 10.

In the real number line it is all the numbers to the left of 10, including 10.

So, the matching graph is the A.


c. 5x ≥ 20

Divide both sides by 5 => x ≥ 4

That is all the real numbers greater or equal to 4.

In the real number line it is all the numbers to the right of 4, including 4.

The matching graph is C.</span>

Solve the system of equations below algebraically <br> 2x+3y=6 and -5x+2y=4
Charra [1.4K]


Steps
I’m using elimination so I’m trying to get rid of y
To do that I multiply the first equation by 2 and the second by -3. Then solve
4x + 6x = 12
15x + -6x = -12
—————————
19x + 0 = 0
Divid by 19 to get x to one side. 0/19 is 0 so
X= 0
Plug that into an equation so 0 + 3y = 6
Divid by 3 and y = 2
Answer x = 0 y = 2
