Answer:
12
Step-by-step explanation:
x = 2n
2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 80
10n = 60
n = 6
x = 12
12 + 14 + 16 + 18 + 20 = 80
Answer:

Step-by-step explanation:
From the question we are told that:
Diameter 
Number of times jogged
Generally the equation for Distance traveled is mathematically given by
D=Circumference of Park * Number of times jogged
Where
Circumference of Park c is mathematically give as



Therefore



Answer:
264.89cm^2
Step-by-step explanation:
CSA of cylinder=πrl
= 3.1 × 7 ×√149
= 264.89cm^2
$61 x 3= $183
$183 x .08225= 15.11
$183 + 15.11= $198.11
B. -13/3 because 6-(-7)/-1-2 = -13/3
