A = r² π
254.469 = r² π
r² = 254.469 : 3.14159
r² = 81.00866
r = 9.0048
C = 2 r π = 2 * 9.0048 * 3.14159 = 56.55 units
Sale price = cost price ( 1 - sales tax)
sales price = 21.60 ( 1- .08)
sales price = $19.872

Step-by-step explanation:
They are asking for a ratio based on how many chaperones per student (in this case 15 students) In other words 15 students for every 2 chaperones.
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = intercept
m = slope
The equation of the given line is
3x+y=10
y = - 3x + c
Comparing it with the slope intercept equation, slope, m = -3
If a line is parallel to another line, the slope of the line is the same with the slope of the given line. This means that the slope of the line passing through the point (-2,4) is -3
We would determine the intercept, c by substituting m = -3, x = -2 and y = 4 into y = mx + c. It becomes
4 = -3 × -2 + c
4 = 6 + c
c = 4 - 6 = - 2
The equation becomes
y = - 3x + - 2
Answer:
common difference(d) = 11
first term (a)=11
then the nth term
=a+(n-1)d
=11+ (n-1)*11
=11+11n-11
=11n
