Answer:
745.44 mm² (nearest hundredth)
Step-by-step explanation:
Section the shape into a semicircle, a rectangle and a triangle by drawing a line vertically through the point, and a vertical line upwards from the corner of the 12.5 mm and 32.5 mm corner.
area of semicircle = (1/2) 
r² = 78.125 mm²
area of the rectangle = 12.5 x 25 = 312.5 mm²
area of triangle = 1/2 x (55 - 25) x 12.5 = 187.5 mm²
total area = 312.5 + 78.125 + 187.5 = 745.44 mm² (nearest hundredth)

Answer:
66
Step-by-step explanation:
<u>year 1: 35% of 27</u>
convert 35% into a decimal :0.35
0.35 x 27= 9.45
27+ 9.45= 36.45 , thats what you have left at the end of year 1
<u>year 2: 35% of 36.45</u>
0.35 x 36.45= 12.7575
36.45 + 12.7575= 49.2075, thats whats left at the end of year 2
<u>year 3: 35% of 49.2075</u>
0.35 x 49.2075= 17.222625
49.2075+ 17.222625= 66.430125, thats whats left at the end of the 3rd year.
you cant have 66.430125 of a guppy so it rounds to a whole number- 66
