I guess it would be true because 100+95+85+80 = 360, and there are 360 degrees in a circle.

To check if a circle can be circumscribed about a certain quadrilateral, the opposite angles in the quadrilateral have to add up to 180 degrees.

--------

In your question, the opposite angles in the quadrilateral add up to:

85° + 80° = 165°

and 95° + 100° = 195°

----------------------------------------------------------------

Answer:

As you can see, neither 165° or 195° is 180°.

Therefore the answer is False

------------------------------------------------------------------------------------

Note:

If it's still not to clear for you, then say so and I will provide a diagram to make it clearer,

----------------------------------------------------

Additional Info:

Another word for a quadrilateral that can have a circle circumscribed about it is 'Cyclic'.

For example, some shapes are 'Cyclic quadrilaterals'

(which means it is a quadrilateral that can fit perfectly into a circle, with all edges touch the circumference)

The answer is D, or 168.
The cheese can be any one out of 3 = 3 choices. For each of those . . .
The first topping can be any one of 8. For each of those . . .
The second topping can be any one of the remaining 7 . For each of those . . .
The third topping can be any one of the remaining 6 .

Total number of ways to assemble a pizza = (3 x 8 x 7 x 6) = 1,008 ways.

BUT . . . 

You could choose the SAME 3 toppings in (3 x 2) = 6 different ways, and
nobody could tell the difference once they were selected. All 6 different
ways would result in the same pizza.

So, out of the 1,008 total different ways there are of choosing ingredients,
there are only ( 1,008 / 6 ) = 168 different and distinct pizzas.

Answer:

$y=\cfrac{1}{2}\;x-4$

x | y

10 1 = 1/2 (10) -4=5-5= 1

-2 -5 = 1/2(-2)-4=-1-4= -5

4 -2 = 1/2(4)-4=2-4= -2

-8 -8 = 1/2(-8)-4=-4-4= -8

Answer:

Step-by-step explanation:

One pump will fill 200l in 20 minutes

So the rate of filling per pump will be 10l/minute (200/20)

Let the number of minutes it will take to fill the 600l be x minutes

Now, since the rate of filling per pump is 10 l/minute

Then in x minute, they would have filled 10l/minute * x = 10x liters

So it is now this 10x liters that will be equal to 600

To find x, we simply divide

10x = 600

x= 600/10

x = 6 minutes

What is the solution set of {x | x > -5} {x | x < 5}?

Yuri [45]

Answer:

The numbers between -5 and 5

Step-by-step explanation:

Intersection of Intervals

Given the intervals A,B,C,etc. The intersection of them all is the set of all values that are common to all the intervals.

We must find

$\{x | x > -5\} \bigcap \ \{x | x < 5\}$

which is the intersection between the intervals x > -5 and x < 5. The intersection represents all the numbers greater than -5 and less than 5. It can also be said The numbers between -5 and 5 (non inclusive), third option
