Answer:

r = c / 2π

Step-by-step explanation:

c = 2πr is the formula for the circumference of a circle of radius r.

We can solve this for r:

r = c / (2pi)

r = c / 2π

Answer:

690%

Step-by-step explanation:

To find the percent increase, take the new amount and subtract the original amount

5600000-80000=5520000

Divide it by the original amount

5520000/800000

6.9

Multiply this by 100% to change from decimal form to percent form

6.9*100%

Sergeu [11.5K]

Answer:

6/95.

Step-by-step explanation:

Prob(red marble on the first choice) = 4/(10+6+4)

= 4/20

= 1/5.

Prob(green marble on the second draw) = 6/19.

Prob( read then a green)

= 1/5 * 6/19

= 6/95.

Consider the linear function that is represented by the equation Y =-10x+6 and the linear function that is represented

laiz [17]

Answer:

(a) The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

Step-by-step explanation:

If we take the "steepness" of the slope to be the absolute value of the slope, then the line y=-10x +6 has a slope with a steepness of 10.

The line y -36 - 8(x -4) has a slope with a steepness of 8, so the first line is steeper.

The line y=-10x+6 has a y-intercept of 6. The line y-36 =8(x -4) has a y-intercept of 4, so the first line has a higher y-intercept.

The appropriate description of the two lines is ...

The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

Solve the following system y= x+ 3 3x +y = 19

Ratling [72]

3x+y=19

y=19-3x and y=x+3, at a solution both x and y are equal so we can say y=y:

19-3x=x+3

19-4x=3

-4x=-16

x=4, and since y=x+3

y=7 so the solution is the point:
