Answer:

circumference is 18.84

area is 28.26

Step-by-step explanation:

circumference of a circle is

2πr where r is radius

= 6×3.14= 18.8

area of a circle is πr²

= 3×3×3.14

= 28.26

use π = 3.14

Lol


trouble varies directly as distance
lets say t=trouble and d=distance
t=kd
k is constant

given
when t=20, and d=400
find k
20=400k
divide by 400 both sides
1/20=k



t=(1/20)d

given, d=60
find t

t=(1/20)60
t=60/20
t=3

What is the solution to the system of equations?
natka813 [3]

Answer:

Step-by-step explanation:

There is an error in the question. The table does not show two linear functions.  y₁ is a linear function, but   y₂ is not a straight line. It makes a bend at (-6,1).

Line 1 goes through (-12,-3) and (0,5).

slope  = (5-(-3))/(0-(-12)) = 2/3

y-intercept = 5

y₁ = (2/3)x + 5

Line 2 goes through (-12,-2) and (-6,1).

slope = (1-(-2))/(-6-(-12)) = 1/2

y₂ = (1/2)x + 4

(2/3)x + 5 = (1/2)x + 4

x = -6

y = (2/3)x + 5 = 1

Solution: (-6,1)

Solves the inequality. Write your final answer in interval notation:<br><br> -3(2x+1) &gt; -2(x+6)
3241004551 [841]

-3(2x+1) > -2(x+6)

-6x -3 > -2x - 12


-6x -3+6x > -2x - 12+6x


-3>4x-12


-3+12>4x-12+12

9 > 4x

4x<9

x<4/9
