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

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

Miguel can use all or part of his $25 gift card to make a music purchase. Each song costs $1.50, and there is a $1.00 per accoun

Sergeu [11.5K]

Answer:

1 + 1.5 m less-than-or-equal-to 25

25 greater-than-or-equal-to 1 + 1.5 m

Step-by-step explanation:

Available amount $25

Cost of a song= $1.5

One of fee= $1

Number of songs= m

25 ≥ 1+1.5m

1 + 1.5m ≤ 25

is the required inequality

-----------

Correct answer choices:

1 + 1.5 m less-than-or-equal-to 25
25 greater-than-or-equal-to 1 + 1.5 m

1. The equation y=x^2-9x+20 models the roller coasters path over time. The variable y represents height (in feet) above or below

azamat

Answer:

1) the factored form is y= ( x-5 ) ( x+4 )

2) the vertex is (4.5, -0.25)

3) the y intercept is when x equals 0 so it is at (0,20)

4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)

a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)

b. it is taken at the vertex aka the lowest point so the height is -0.25
