A circle has a central angle measuring startfraction 7 pi over 6 endfraction radians that intersects an arc of length 18 cm. wha
mash [69]

The radius of this circle is (B) 4.9 cm.

<h3>To find the radius of the circle:</h3>

To solve this problem, we need to, first of all, convert the angle from radians to degrees.

data;

  • length of an arc = 18cm
  • angle = 7/6π rads
  • π= 3.14

\frac{7\pi }{6rads} =210^{0}

Length of an Arc:

The formula for the length of an arc is given:

l_{arc} = θ/360 × 2\pi r

Let's substitute the values and solve:

18=\frac{210}{360} *2\pi r\\18=3.663r\\r=\frac{18}{3.663} \\r=4.9cm

From the calculations above, the radius of this circle is 4.9cm.

Therefore, the radius of this circle is (B) 4.9 cm.

A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was
faltersainse [42]

a.

Let

5x = number of games won

2x = number of games lost

The total number of win and lose is 154. So

5x + 2x = 154

Solving for x,

7x = 154

x = 22

Therefore, the number of games won is 5*22=110 and the number of games lost is 2*22 is 44.

b.

Let

6x = first side of the triangle

7x = second side of the triangle

9x = third side of the triangle

The perimeter of a triangle is the total of all sides. So,

6x + 7x + 9x = 88

22x = 88

x = 4

Therefore, the three lengths of the side are 6*4=24, 7*4=28, and 9*4 = 36

Mandy told Bill that she has read 16 books this year and reads 2 books each month. Bill wants to catch up to Mandy. He tracks hi
Lostsunrise [7]
We need to write equation for both mandy and bill on how many books they read depending on how many months passed.

Mandy's equation:
16 + 2x

she starts with 16 read books and she reads 2 books each month which is in total 2*x where x is number of months

Bill's equation:
4x
because from table we can see he is reading 4 new books each month.

now we need to make those 2 equations equal to eachother and solve for x because we want to see after how many months both will read the same that is why we set them equal.

16 + 2x = 4x
16 = 2x
x = 8

That means that in december he will catch her (if i counted months correctly :) )
