<span>a. True The question is pretty much the entire definition of a radian. For an unit circle, its entire circumference is 2π and the entire circle has 2π radians. A quarter circle, or 90°, or π/2 radians, have 1/4th of the circumference. And 2π/4 is π/2. This natural relationship is WHY higher mathematics uses radians for the measurement of angles rather than arbitrary units such as degrees.</span>

Is negitive 1.8 greater than negitive 2.1
Llana [10]
Unlike positives, with negatives, the larger a number is, the smaller it is.

Example : 
4 > 2

-4 < -2

so -1.8 is GREATER then -2.1

here is a tip :
picture ur number line....plot -2.1....any number to the right is greater and any number to the left is less...and since -1.8 is to the right of -2.1, it is greater then -2.1

Which number line represents the solution set for the inequality 3(8 – 4x) &lt; 6(x – 5)?
diamong [38]

Answer:

  A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right.

Step-by-step explanation:

We can start by dividing the inequality by 3 to get ...

  8 -4x < 2(x -5)

And we can divide by 2 to simplify further to ...

  4 -2x < x -5

Now, we can add 2x+5, which gives ...

  9 < 3x

and then divide by 3 again:

  3 < x

This is graphed on a number line as described above.
