Total degrees of a circle: 360’
Pie chart total: 360’/10=36

So every angle divided by 10 equals the number of pupils:

Bus: 120’/10=12 pupils.
Walk: 90’/10=9 pupils.

360’-(120’-90’)=150’ remaining

150’/2=75’

Car and bike are equal:

75’/2=7.5 pupils for car and bike.

A function f is defined by f:x=3-2sinx for 0
Gala2k [10]
       f(x) = 3 - 2sin(x)
          0 = 3 - 2sin(x)
        - 3  - 3
         -3 = -2sin(x)
         -2        -2
        1¹/₂ = sin(x)
sin⁻¹(1¹/₂) = sin⁻¹[sin(x)]
sin⁻¹(1¹/₂) = x

Area of Composite Figures
AlekseyPX

Answer:

1) 147

2) 87m^{2}  

Step-by-step explanation:

1) Area of triangle = × base length × height

= \frac{1}{2} × 14 × 10

= 70 m^{2}

Area of a semicircle = \frac{\pi r^{2} }{2} ( r is the radius)

Radius = half of diameter = \frac{14}{2} = 7m

Area of semicircle = \frac{\pi 7^{2} }{2} = \frac{\pi49 }{2}

= 77m^{2} ( Nearest whole number )

Total area = 77 + 70 = 147m^{2}

2) Divide the shape into 2 rectangles

Area of a rectangle = length × width

Rectangle 1 = 7 × ( 3+3+5 )

= 7 × 11 = 77m^{2}

Rectangle 2 = 2 × 5

= 10m^{2}

Total Area = 77 + 10 = 87m^{2}

Which of the following is a factor of (x+y)³-(x+y)³
IgorC [24]

▬▬▬▬▬▬▬▬▬▬▬▬▬▬

<h3>Answer :</h3>

The factor of (x + y)³- (x³ + y³) is <u>3xy</u>

<h3>Step By Step Solution :</h3>

→ (x + y)³- (x³ + y³)

→ (x + y) - (x + y)(x² - xy + y²) [Using identity a³ + b³ = (a + b)(a²- ab+ b²)]

→ (x + y)(x² + y² + 2xy - x² + xy - y²)[Using identity, (a + b)² = (a² + b²+ 2ab)]

→ (x + y) (3xy)

→ 3xy

∴ Option d. 3xy is correct!

faltersainse [42]
Ratio of Anne : Mark : Ben = 20 : 35 : 25
= 4 : 7 : 5 ( total 16 parts )

Anne = 4/16 x £80 = £20

Mark = 7/16 x £80 = £35

Ben = 5/16 x £80 = £25
