Jane would have passed the test with ~92%
55 ÷ 60 = 9.166666-
324 (oil paintings) + 227 (watercolor paintings) = 551
You need to know how many more oil and watercolor paintings there are than statues so you take those 158 statues from 551 oil and watercolor paintings:
551-158= 393 --> there are 393 more oil and watercolor paintings than statues in the museum
The answer is the first and third one
Answer:
30.28 yd²
Step-by-step explanation:
Area enclosed = area of trapezoid + area of semicircle
= ½(a + b)*h + ½(πr²)
Where,
a = 5 yd
b = 2 + 5 = 7 yd
h = 4 yd
r = ½(4) = 2 yd
Plug in the known values
Area enclosed = ½(5 + 7)*4 + ½(π*2²)
Area enclosed = ½(12)*4 + ½(π*4)
= 6*4 + π*2
= 24 + 2π
= 30.2831853
≈ 30.28 yd² (2 decimal places)
