Answer:
x=141
Step-by-step explanation:
(n-2)•180 = Sum of all the interior angles
n = # of sides
(7-2)•180
5•180
900= Sum of all the interior angles
Add all the angles and equal them to 900
125+122+131+x+7+x+107+x-15=900
Add all the numbers up first on the left side
477+3x=900
3x=423
x=141

Answer:
$4040.57
Step-by-step explanation:
A=P(1+(r/n))^nt
P = Principal = 3000
r = rate = 0.03
n = no. times payed each year = 2
t = years = 10
A = 3000(1 + (0.03/2))^(2x10)
A = 3000(1.015)^20
A = 4040.57 (2.d.p)
Hope this helped!
 
        
             
        
        
        
Answer:
   B.  2010.62 ft³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
   V = πr²h . . . . . where r is the radius and h is the height
Filling in the numbers and doing the arithmetic, we get ...
   V = π(8 ft)²(10 ft) = 640π ft³ ≈ 2010.6193 ft³ ≈ 2010.62 ft³
The volume of the cylinder is about 2010.62 ft³.
