Answer:
1) The slant height = 9.8 cm ⇒ (C)
2) The slant height = 11.4 cm ⇒ (D)
Step-by-step explanation:
1) ∵ The slant height of the cone = √[(radius)² + (height)²]
∵ Diameter = 8 cm
∴ Radius = 4 cm
∵ Height = 9 cm
∴ Slant height = √(4² + 9²) = √97 = 9.8 cm ⇒ (C)
2) ∵ The slant height of the cone = √[(radius)² + (height)²]
∵ Diameter = 18 cm
∴ Radius = 9 cm
∵ Height = 7 cm
∴ Slant height = √(9² + 7²) = √130 = 11.4 cm ⇒ (D)
B. 20x+50.

Answer:
Difference in cash and plan = $155 - $149.50 = $5.50
Interest Rate = 3.68%
Step-by-step explanation:
Given:A food processor for $149.50 cash, or $5.00 down and $10.00 per month for 15 months
A food processor by cash = $149.50
Payment plan = Down payment + $10*15 months
= $5 + $10*15
= $5 + $150
Payment plan = $155
Difference in cash and plan = $155 - $149.50 = $5.50
Now we have to find the interest rate
= (difference/original)*100
= (5.50/149.50)*100
Interest Rate = 3.68%
