A central angle measuring 120° intercepts an arc in a circle whose radius is 3.

Mathematics

Kisachek [45]4 years ago

Answer:

6.28

Step-by-step explanation:

The length of arc which subtends an angle \alpha at the center of a circle is given by \alpha r where r is the radius of circle.

______________________________

given

the central angle of arc is  120°

\pi = 180\\120 = (\pi /180)* 120\\120 = 2/3\pi

we will use value of \pi as 3.14

r = 3

Length of this arc is

2/3( \pi *3) = 2\pi \\=2*3.14 = 6.28

The length of the arc to the nearest hundredth of unit is 6.28

Which statement is true about the graph of two lines y=-6 and x=1/6
Gelneren [198K]
The graph of the line y = -6 is a horizontal line which passes through the y axis at -6. On the other hand, the graph of the equation, x = 1/6 is a vertical line that passes through the x-axis at 1/6. The intersection of these lines is at a point that is expressed as (1/6, -6).

Which of the following ratios is equivalent to 49:35?
Arte-miy333 [17]

The best way to find it is to reduce each ratio you work with to its
lowest terms,and see which ones are equal. To reduce a ratio to its
lowest terms, divide each number by their greatest common factor.

First, the one that you're trying to match:  <u>49:35</u> .
The greatest common factor of 49 and 35 is 7 .
Divide each number by 7 . . .  <em>7:5</em> . . . <u>that's</u> what you have to match.

<u>7:4</u>
Their greatest common factor is ' 1 '.
No help at all, and this one is not it.

<u>14:25</u>
Again, their greatest common factor is '1 '.
No help at all, and this one is not it.

<u>21:15</u>
Their greatest common factor is ' 3 '.
Divide both numbers by 3 . . . <em>7:5 </em>.
That's it !

Can some one help me answer all ten questions they are due at 10:00 I will give out brainly. Part 3 Bonus question
mixer [17]

Answer:

226

Step-by-step explanation:

Area of rectangle:

x+6=17

x=11

11+6=17

11+3=14

17×14=238

Area of triangle:

\frac{1}{2}  \times b \times h

Use phytagoras theorem to find the base of the triangle:

c²=a²+b²

5²=4²+b²

25=16+b²

b²=25-16

b²=9

b=√9

b=3 (only the half)

b=6 (the whole base)

\frac{1}{2}  \times 6 \times 4

3×4

12

Shades region:

238-12

=226

If mc008-1.jpg, what is f(5.9)?
yulyashka [42]
The answer:

the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?

9
10
11
<span>12

</span>first, [x - 2 ] is called the integer part of x-2, 
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so <span>f(5.9) = 3 [ 5.9 - 2 ] =  3 [ 3.9 ]

 as we know that </span>[ 3.9 ]=3
<span>
therefore
</span>3 [ 3.9 ]<span>= 3x3 =9

the answer is 9</span>
