Rob buy 6 tickets to the basketball game he pays $8.50 for parking. His total cost is $40.54. What is the cost of each ticket?

Natalija [7]

The cost of all the tickets is 32.04

Subtract $8.50 from $40.54 to leave you with the ticket costs.

Each individual ticket would be 5.34. You get this because $32.04 divided by six tickets is the cost of one.

Find area of the shaded portion of the figure

Nikitich [7]

Answer:

$\sf C) \quad 57 \frac34 \:cm^2$

Step-by-step explanation:

To find the shaded area, subtract the area of the semicircle from the area of the rectangle.

Formulae

$\textsf{Area of a rectangle}=\textsf{width} \times \textsf{length}$

$\textsf{Area of a semicircle}=\dfrac12 \pi r^2 \quad \textsf{(where r is the radius)}$

$\textsf{Diameter of a circle}=2r \quad \textsf{(where r is the radius)}$

Area of rectangle

Given dimensions of the rectangle:

width = 7 cm
length = 11 cm

Substituting these values into the formula:

$\implies \textsf{Area}=\textsf{7} \times \textsf{11}=77\: \sf cm^2$

Area of semicircle

Diameter of semicircle = 11 - 2 - 2 = 7 cm

⇒ Radius (r) = 7 ÷ 2 = 3.5 cm

$\textsf{let}\: \pi=\dfrac{22}{7}$

$\implies \textsf{Area}=\dfrac12 \left(\dfrac{22}{7}\right) (3.5)^2=19.25\: \sf cm^2$

Area of shaded region

= area of rectangle - area of semicircle

= 77 - 19.25

= 57.75

$\sf =57 \frac34 \:cm^2$
