Number of people who bought fewer than 30 items is (0.14 + 0.12 + 0.24)400 = 0.51 x 400 = 204
Answer:
Area of Shaded Region 
Area of Semicircle 

Step-by-step explanation:
Area of Shaded Region = Area of Sector - Area of Semicircle
<u>Area of Sector</u>
Radius of the sector =20cm

<u>Area of Semicircle</u>
Since AB is the diameter of the semicircle
Radius of the Semicircle=20/2=10cm
Area of semicircle

Therefore, area of Shaded Region

Area of Square =20 X 20 

Answer: Choice B) 17.5 feet
A = Area of rectangle
L = length
W = width
The formula to use is A = L*W, so we multiply length and width.
We know W = 7 but we don't know what L is.
We know that A = 122.5 is also given
So let's solve for L
A = L*W
L*W = A
L*7 = 122.5 plug in the given values
7*L = 122.5
7*L/7 = 122.5/7 divide both sides by 7
L = 17.5
He should cut 17.5 feet of streamer. Keep in mind that this only applies if Adrian wants to make the streamer completely taut and a straight line across the ceiling/wall. If he wants the streamer to hang down a bit (forming a shape like a rope bridge in a sense), then the streamer's length will have to be a bit longer to account for the extra distance along the curve.
A trapezoid is a quadrilateral with one pair of parallel sides. The formula for the area of a trapezoid is ↓
Area =
(base 1 + base 2) h
The bases of the trapezoid are the parallel sides.
In the trapezoid shown, the bases are 22.2 cm and 8.52 cm and the height of the trapezoid is 9.86 cm. Now, we can plug these numbers into our formula.
(22.2 cm + 8.52 cm) (9.86 cm)
Next, the order of operations tells us that we need to simplify inside the parentheses first. 22.2 + 8.52 = 30.72 cm
(30.72 cm) (9.86 cm)
× 30.72 = 15.36
(15.36 cm) (9.86 cm) = 151.4496 cm²
