15*9=135+135=270
18*12=216+216=432
9*18=162
270+432+162=864

C.864 is the answer

Sav [38]

Answer:

The network model is attached.

Step-by-step explanation:

Total Demand from each Gas Company are:

Southern Gas, 500 units;

Northwest Gas, 400 units.

Total Supplies to each County are:

Hamilton County, 400 units;

Butler County, 200 units;

Clermont County, 300 units.

The distribution costs per unit (in thousands of dollars) are as follows

-----------Hamilton-- Butler-- Clermont

Southern Gas--- 10 ---20--- 15

Northwest Gas ----12 ----15---- 18

The network representation of these information is given in the attachment.

Thethree sides of a triangle measure 810 and 12 units is this a right angle?

Alja [10]

Answer:

The given triangle is NOT A RIGHT ANGLED TRIANGLE.

Step-by-step explanation:

Here, the three given sides of the triangle are:

8 units, 10 units and 12 units

Now, for any triangle to be a right angle:

by the PYTHAGORAS THEOREM:

$(Base)^2 + (Perpendicular)^2 = (Hypotenuse)^2$

The longest of all sides id the hypotenuse.

⇒ H = 12 units

Let us assume, B = 8 units, P = 10 units

Now, here checking the condition:

$(8)^2 + (10)^2 = 64 + 100 = 164 \neq (12)^2 = 144\\\implies (B)^2 + (P)^2 \neq (H)^2$

Hence, the given triangle is NOT A RIGHT ANGLED TRIANGLE.

Which of the following is the conjugate of a complex number with 2 as the real part and 7i as the imaginary part? (5 points)

lisov135 [29]

The complex conjugate of 7i is −7i The complex conjugate of a number

z is a number with opposite imaginary part.

So if z=a+bi then conjugate is: ¯z=a−bi for any a,b∈R

We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate ¯z are symetrical according to "real part" axis.
