Answer:
Final cost = 0.9328y
Step-by-step explanation:
Assume,
Original price = y
Given:
Discount = 22%
Sales tax = 6%
Computation:
Sales tax will be added on sale value
So,
Sales price = y[100%-22%]
Sales price = 0.88y
Price after sales tax :
Final cost = 0.88y[100% + 6%]
Final cost = 0.88y[106%]
Final cost = 0.9328y

Answer:
24 square centimeters
Step-by-step explanation:
How much space does the triangle cover? Triangle with a base of 4 cm and a height of 12 cm
We are to find the area of the triangle
Area of the Triangle = 1/2 × Base × Height
= 1/2 × 4 × 12
= 24 square centimeters.
Therefore, the triangle will cover a space of 24 square centimeters.
Answer:
13. 9.77 inches (rounded to 3 s.f.)
14. 249m² (rounded to 3 s.f.)
Step-by-step explanation:
13. To find the arc length, the formula is the angle of the arc out of 360° multiplied by the circumference of the full circle. Circumference of circle: pi × r × 2
× pi × 7 × 2 = 3
pi
= 9.77 inches (rounded to 3 s.f.)
14. To find the sector area, the formula is the angle of the sector out of 360° multiplied by the area of the full circle. Area of circle: pi × r × r
× pi × 10 × 10 = 79
pi
= 249m² (rounded to 3 s.f.)
