Answer:
t > 1380
Step-by-step explanation:
Subtract 7200 from both sides
10t + 7200 - 7200 > 21000 - 7200
Simplify
10t > 13800
Divide both sides by 10
10t/10 > 13800/10
Simplify
t > 1380

115/23= 5
Answer:
x=-3/11
Step-by-step explanation:
(x+3)/5 +2x=0
Multiply both sides by 5 to get rid of the fraction
5*( x+3)/5 +5*2x=0*5
x+3 + 10x =0
Combine like terms
11x +3 = 0
Subtract 3 from both sides
11x+3-3 =0-3
11x = -3
Divide by 11
11x/11 = -3/11
x = -3/11
Answer: 10 inches.
Step-by-step explanation:
Since the pecan pie is a circle, you can use this formula:
Where "r" is the radius and 
is the central angle of the arc in radians.
If the pecan pie has been cut into 8 equal pieces then the central angle is:
Now you know the arc length and the central angle, then, you can solve for "r" from :
Substituting values, you get that the radius of the pecan pie rounded to the nearest whole number is:
