Answer:

Option B

Step-by-step explanation:

In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So

5 + 12 > k

=  > 17 > k

Hence the measure of k is less than 17.

In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because <u>if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.</u>

Atlast , the range of k is :-

7 < k < 17

Which three values are greater than
solniwko [45]

Answer:

3/4 is greater than 1/2

45% = 9/20 is less than 1/2

1/3 is less than 1/2

0.62 is greater than 1/2

59% = 59/100 is greater than 1/2

0.315 is less than 1/2

So, A, D and E are greater than 1/2

Hope this helps!

What is the midpoint of AB?
Citrus2011 [14]

Answer:

(-4, -\frac{1}{2})

Step-by-step explanation:

Hi there!

We are given the line segment, with the end points AB

The coordinates of A are (-5, -4), and the coordinates of B are (-3, 3).

We want to find the midpoint of the line segment AB

The midpoint formula is given as (\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2}), where (x_1, y_1) and (x_2, y_2) are coordinates

We have two coordinates, which is what we need, but let's label their values to avoid any confusion:

x_1=-5\\y_1=-4\\x_2=-3\\y_2=3

Now substitute those values into the formula:

(\frac{x_1+ x_2}{2}, \frac{y_1 + y_2}{2})

(\frac{-5+ -3}{2}, \frac{-4+ 3}{2})

Now simplify the numerator and denominator

(\frac{-8}{2}, \frac{-1}{2})

Simplify again:

The midpoint is (-4, -\frac{1}{2})

Hope this helps!
