So, the sum of two sides have to be greater than the third side for it to create a triangle.

Option A:

4 + 6 = 10

The first 2 sides aren't greater than the third side so, this is incorrect.

Option B:

4 + 5 = 9

The first 2 sides aren't greater than the third side so, this incorrect.

Option C:

5 + 6 = 11

The first 2 sides aren't greater than the third side so, this incorrect.

Option D:

5 + 5 = 10

The first 2 sides are greater than the third side so, this correct.

Therefore, the answer is Option D.

Best of Luck!

Answer:

The cost per duck is $5.00 and $8.00 for chickens

Step-by-step explanation:

The equation would be like this:

50c + 30d = 550 (divide this by 10)

5c + 3d = 55

3d = 55 - 5c (multiply by 3)

9d = 165 - 15c

Next,

44c + 36d = 532 (divide this by 4)

11c + 9d = 133

11c + 165 - 15c = 133

11c - 15c = 133 - 165

-4c = -32 (divide by -4)

c = 8

Therefore, the cost of each chicken is $8.00

9d = 165 - 15c

9d = 165 - 15(8)

9d = 165 - 120

9d = 45 (divide by 9)

d = 5

Question 7(Multiple Choice Worth 1 points)

lana66690 [7]

Answer:

Option A.

Step-by-step explanation:

The given function is

$f(x)=0.15x^2-6x+400$

Leading coefficient is positive, so it is an upward parabola. Vertex of an upward parabola is the point of minima.

Vertex of a parabola $f(x)=ax^2+bx+c$ is

$Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)$

In the given function a=0.15, b=-6 and x=400.

$-\dfrac{b}{2a}=-\dfrac{-6}{2(0.15)}=20$

At x=20,

$f(20)=0.15(20)^2-6(20)+400=340$

So, minimum value of f(x) is 340 at x=20.

From the given table it is clear that the minimum value of g(x) is 55 at x=70.

Since 55 < 340, therefore, g(x) has a lower minimum values, i.e, (70,55).

Hence, option A is correct.
