Bond [772]

the complete question in the attached figure

Let
A°-----------> the same central angle

For the larger circle
length of larger circle=2*pi*r-------> 2*pi*12-----> 75.36 m

360° (full circle) has a length of------------> 75.36 m
A°-----------------------------------> 16 m
A°=(16)*360/75.36--------> A=76.43°

For the smaller circle
length of smaller circle=2pi*r-------> 2*pi*7.5-----> 47.1 m

360° (full circle) has a length of------------> 47.1 m
76.43°-----------------------------------> X
X=76.43*47.1/360-----> X=10 m ----> length arc of the smaller circle

the answer is
the length arc of the smaller circle is 10 m

B^2-5b+3 for b=-3 plz help

nika2105 [10]

Hey there!

b^2 - 5b + 3

= -3^2 - 5(-3) + 3

= -9 - (-15) + 3

= -9 + 15 + 3

= 6 + 3

= 9

Answer: 9

Good luck on your assignment and enjoy your day!

If AC = 20 centimeters, and BC = 16 centimeters, which does AB equal?

Anna11 [10]

Answer:

The answer is B. 12 cm

Step-by-step explanation:

ABC is a right triangle

AB and BC are the legs and AC is the hypotenuse.

The Pythagorean theorem a^2 + b^2 = c^2 can be manipulated to solve for a and get 12.

7 - 5n = 6 + 6(n + 2)

postnew [5]

7- 5n=6+6(n+2)
7- 5n=6+6n+12
7 -5n=18+6n
5n-6n=18-7
-11n=11
n=-1
