Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{\frac{\pi }{2} }{2\pi } ( r is the radius )

    = 2π × 3.5 × \frac{1}{4}

    = \frac{7\pi }{4}

    ≈ 5.5 ( to the nearest tenth )

For the first one is definitely 0.12 
The second one I was having trouble with, but I know it is not .25 or .75. Looking at the leftover answers I would say .36 because I already used .12. Also .52 and .25 are the givens.

Find the value of x in each case. Give reasons to justify your solutions!
ANEK [815]

Answer:

  x = 11°

Step-by-step explanation:

The parallel lines suggest we look to the relationships involving angles and transversals. The angle marked 33° and ∠CAB are alternate interior angles, hence congruent:

  ∠CAB = 33°

5x is the measure of the external angle opposite that internal angle and angle 2x of ΔABC, so it is equal to their sum:

  5x = 2x + 33°

  3x = 33° . . . . . . . . . subtract 2x

  x = 11° . . . . . . . . . . . divide by 3

How to Simplify the following expression<br> −3x2+5−12x−149x2
laila [671]
Multiply the numbers: 3 x 2=6 = 6x + 5 - 12x - 2 x 149x 
Next Multiply the numbers 149 x 2 = 298

Then, Group like terms, =-6x-12x-298x+5

Add similar elements -6x-12x-298x=-316x,
and you get -316x+5!
