La formula para calcular cualquier descuento esta dada por (100 - descuento)/100
en ese caso seria Y = (1-0.3)X = 0.7X
Answer:
C. 7
49 square rooted would be 7 and the 4 in (x+4) would be negative and not positive like the answer shows.
This equation would be represented as a No Solution equation. Due to the fact that if you do inverse operation and combine like terms, your variables will cancel out.
Answer: 463.96 mm² or 46.4 cm²
Step-by-step explanation:
Quarters are circular in shape so the surface area of one side will be the area of a circle.
Area of a circle = π * r²
Radius = Diameter / 2
= 24.3 / 2
= 12.15 mm
Area = 22/7 * 12.15²
= 463.96 mm²
