The solution has to be a value of x. Since you already have x, you just have to plug in the value and see what fits. In this case thats the third from the top:

5^2 - 10*5 + 25 = 0
25 - 50 + 25 = 0
0 = 0

Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi. (4 points) C = 11π;
Iteru [2.4K]

Answer:

C = 22π; A = 121π.

Step-by-step explanation:

To find the circumference of a circle, you do pi times the diameter. That would be 22pi.

To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.

So, C = 22pi; A = 121pi.

Hope this helps!

What is 4 2/7 as an improper fraction?<br> HURRYYYYYYY
Alika [10]

Answer: C. 30/7

Step-by-step explanation: To make an improper fraction out of a mixed one we have to multiply the denominator by the whole number (in this case is 4) and then add the numerator. So 7 x 4 = 28 + 2 = 30, so 30/7 would be the correct answer choice.

Hope this helps!

In the diagram of circle R, m∠FGH is 50°. What is m? 130° 230° 260° 310°
omeli [17]

we know that

The measurement of the exterior angle is the semi-difference of the arcs which comprises

In this problem

∠FGH is the exterior angle

∠FGH=50\°

∠FGH=\frac{1}{2}(arc\ FEH-arc\ FH)

50\°=\frac{1}{2}(arc\ FEH-arc\ FH)

100\°=(arc\ FEH-arc\ FH)  -----> equation A

arc\ FEH+arc\ FH=360\°

arc\ FH=360\°-arc\ FEH --------> equation B

Substitute equation B in equation A

100\°=(arc\ FEH-[360\°-arc\ FEH])

100\°=2arc\ FEH-360\°

2arc\ FEH=360\°+100\°

arc\ FEH=230\°

therefore

<u>The answer is</u>

The measure of arc FEH is equal to 230\°
