Answers

Answer 1
Answer:

Answer:

12π ≈ 37.68

Step-by-step explanation:

The Circumference formula is C=πd

Since the radius is 6, the diameter will be 12

Now just plug it in

C = 12π
Answer 2
Answer:

Answer:

37.68

Six mobsters have arrived at the theater for the premiere of the film "Goodbuddies." One of the mobsters, Frankie, is an informer, and he's afraid that another member of his crew, Joey, is on to him. Frankie, wanting to keep Joey in his sights, insists upon standing behind Joey in line at the concession stand, though not necessarily right behind him. How many ways can the six arrange themselves in line such that Frankie’s requirement is satisfied?a. 6
b. 24
c. 120
d. 360
e. 720

Answers

Answer:

D = 360

Step-by-step explanation:

Number of monsters that arrive at the theater = 6

Total number of arrangement for the 6 mobsters = 6!

= 6*5*4*3*2*1

= 720

The chance that Frankie will be behind Joey is half while the chance that Joey will be behind Frankie is half.

Since Frankie wants to stand behind joey in the line though not necessarily behind him, the arrangement can be done in 6!/2 ways

= (6!) 1/2

= 720/2

= 360 ways

The equation of a line is x + 5y = 12. What is the y-intercept of the line? a. 12 b. 512 c. 125 d. −12

Answers

Answer:

c

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 5y = 12 ( subtract x from both sides )

5y = - x + 12 ( divide through by 5 )

y = - (1)/(5) x + (12)/(5) ← in slope- intercept form

with y- intercept c = (12)/(5)

Ron lives 6 miles due north of the ball field, and Stan lives 8 miles due west of the ball field. What is the straight line distance between their homes? (It makes a right triangle.)8 miles


10 miles


20 miles


50 miles

Answers

You would use Pythagoras' theorem (a^2 + b^2 = c^2) because it is a right-angled triangle. 6^2 + 8^2 = 36 + 64 = 100. √100 = 10. So your answer is 10 miles, I hope this helps!
I think it's 20 miles but I don't know if it is
