Explanation

The Inscribed Quadrilateral Theorem states that a quadrilateral can be inscribed in a circle if and only if the opposite angles of the quadrilateral are supplementary

Answer 1: True

Also, Given a triangle, the circumscribed circle is the circle that passes through all three vertices of the triangle. The center of the circumscribed circle is the circumcenter of the triangle, the point where the perpendicular bisectors of the sides meet.

Answer 2: True

How do i work out -2=6+a/5
Kamila [148]

Answer:

a = -40

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • -2 = 6 + \frac{a}{5}
  • -2 = 6 + \frac{1}{5}a
  • -2 = \frac{1}{5}a + 6
  • \frac{1}{5}a + 6 = -2

Step 2: Subtract 6 from both sides.

  • \frac{1}{5}a + 6 - 6 = -2 -6
  • \frac{1}{5}a = -8

Step 3: Multiply both sides by 5.

  • \frac{1}{5}a * 5 = -8 * 5
  • a = -40

Therefore, a = -40. I hope this helped you!

How many positive integers are between 3/2 and 21/4 ?<br> A : 2<br> B : 3<br> C : 4<br> D : 5
kvasek [131]

Answer:

4 integers

Step-by-step explanation:

We are given with two fractions

3/2 = 1.5  and 21/4 = 5.25

Let us draw a number line first and then we plot these two numbers on them.

Please refer to the picture attached. Here we see the number line in black line , where the integers are starting with 0. We have plotted the numbers 1.5  and 5.25  in red.

We are asked to determine the number of integers that lies between 1.5 and 5.25.

The definition of integer says , the whole numbers which be negative also including 0.

Hence we can see that there are 4 whole numbers between 1.5 and 5.25 ,

2,3,4,5

Hence our answer is 4 integer

The profit function is P = 50x + 80y, where x represents the number of chairs and y represents the number of sofas. Using the va
Fantom [35]
Answer: Given the 3 choices in the problem, the greatest profit would be for the final pair (6, 12).

If you input 6 for x in the function and 12 for y in the function, you will get an output profit value of 1260.
P = 50(6) + 80(12)
P = 300 + 960

On these types of problems, there are generally multiple constraints that you have to be aware of. One of the vertices of the possible areas must be (6, 12).
