Answer:

B=-3

Step-by-step explanation:

-11b+7=40

Subtract -7 from both sides

-11b-7=40-7

11b=33

divide by -11

11b/-11=33/-11

-11 and -11 cancel out, leaving you with B=-33/11

thus B=-3

Answer:

Arc length is  \frac{14\pi}{3} ,  or,  14.7

Step-by-step explanation:

AB is an arc intercepted by 140 degree angle. The formula for length of an arc is given by

AL=\frac{\theta}{360}*2\pi r

Where

AL is the arc length

\theta  is the angle (in our case, 140)

r is the radius of the circle (which is 6)

<em>Substituting, we get:</em>

<em>AL=\frac{\theta}{360}*2\pi r\\AL=\frac{140}{360}*2\pi (6)\\AL=\frac{7}{18}*12\pi\\AL=\frac{14\pi}{3}</em>

<em />

<em>In decimal (rounded to tenths) -  14.7</em>

Korolek [52]

Percent increase from 2000 to 2001 is 12% and from 2001 to 2002 is 12.6%. Thus period of 2001 to 2002 has higher increase percentage.

Solution:

Given that,

Total circulation of local newspaper in 2000 = 3250

Total circulation of local newspaper in 2001 = 3640

Total circulation of local newspaper in 2002 = 4100

As we can see 12% < 12.6%

So period of 2001 to 2002 has higher increase percentage.
