Answer:
A. The number of students that the club needs is at least (18).
Step-by-step explanation:
27 is the minimum requirement, so they need at <em>least</em><em> </em>18 people to meet said requirement. They can go over the limit.
The other answer comes into play if 27 was the <em>maximum</em><em> </em>that was allowed. Then they would need at most 18, because they can't admit any more people. They can't go over the limit.
Answer: Dao will pay $ 15,219.2
Step-by-step explanation:
Hi, to answer this question we have to multiply the price of the automobile by the percentage discount in decimal form (divided 100)
18,560 (18/100) = 18,560 (0.18) = $ 3,340.8 (discount amount)
Finally, we have to subtract the discount amount to the automobile's price:
18,560- 3,340.8 =$ 15,219.2
Dao will pay $ 15,219.2.

Answer:
Cost = 616000 DHS per square centimetre.
Step-by-step explanation:
curved surface of a cylinder = 2
rh
r = 7 cm
h = 1400 m = 140000 cm
The outer curved surface area of the cylinder = inner curved surface area of the cylinder
The inner curved surface of the cylinder = 2
rh
= 2 x
x 7 x 140000
= 2 x 22 x 1 x 140000
= 6160000
The inner curved surface of the cylinder is 6160000 square centimetre.
But, the cost of painting is at the rate of 10 DHS per square centimetre.
The inner curved surface of the cylinder = 6.16 x
square centimetre.
cost of painting the inner curved surface area = 
= 616000 DHS per square centimetre
The cost of painting the inner surface is 616000 DHS per square centimetre.
