Answer:

C. 586.2 cm²

Step-by-step explanation:

Area of the figure = area of triangle + area of rectangle + area of semicircle

= (½*b*h) + (L*W) + ½(πr²)

Where,

b = 18 cm

h = 7 cm

L = 22 cm

W = 18 cm

π = 3.14

r = ½(18) = 9 cm

Substitute

Area = (½*18*7) + (22*18) + ½(3.14*9²)

Area = 63 + 396 + 127.17

Area = 586.17 ≈ 586.2 cm²

stealth61 [152]
 Total expense= sum of all expenses incurred 
                       = commission+legal fees+advertising+printing cost+accounting fees

Total amount of shares sold=$ 2000000 x $62.5
                                              =$ 125000000
commission= 4% of the total amount of shares sold                      = .04x12500000
                      =$ 5000000
total expenses= $5000000+$2255500+$450000+$324400+$386000
                        =$8415900
selling expense/share = $8415900/2000000
                                      =$4.21/shareThe total expense per share is $4.21.

Do these equations have infinite solutions 2x + 5y= 31 and 6x -y = 13
katovenus [111]

2x = 31 - 5y \\ x =  \frac{31}{2} -  \frac{5}{2}y

6x = 13 + y \\ x =  \frac{13}{6}  +  \frac{1}{6} y
