Hey can someone help me with #17

Vinvika [58]

D. 54° as you know an external angle has to equal up to 360

when you start plugging in 360 by 36 gives you 10
360 by 40 gives you 9
360 by 45 gives you 8
360 by 54 gives you 6.666 repeating you know that it isn't possible
you cannot have a repeating number of sides as an angle measure
that's how you get that answer

Use a table of signs to solve the inequality

bulgar [2K]

The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

<h3>What is the inequality equation?</h3>

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

The inequality given in the problem is,

$4x + \dfrac{5}{9} - 3x \geq 0$

Simplify the equation first by adding the same terms,

$4x + \dfrac{5}{9} - 3x \geq 0\\4x - 3x+ \dfrac{5}{9} \geq 0\\x+ \dfrac{5}{9} \geq 0\\x\geq-\dfrac{5}{9}$

Now in this case, if the value x is ranges from -5/9 to infinity.

Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

Help on threethx so much

Maru [420]

The answer is 1.5. We can find this by arranging the data set from least to greatest, 011234, and then finding the middle number. Since the amount of spaces is even, we need to find the number in between 1 and 2. The answer is 1.5!

Please mark brainliest.

Hope this helps!
