Answer:
a) yes, as the number of seats (2352) is larger than the total audience (1912)
b) 440 empty seats
Step-by-step explanation:
a) total number of seats = number of rows x number of seats in each row
total number of seats = 49 x 48
total number of seats = 2352 seats
total audience = 1854 students + 58 teachers
total audience = 1912 people
b) empty seats = total number of seats - total audience
empty seats = 2352 - 1912
empty seats = 440

Answer:
1/18
Step-by-step explanation:
-(-5/9) would turn into a positive 5/9. It cancels its own negative out.
The problem then turns to -1/2+5/9. Find the least common denominator and then combine.
Answer: 89.6 kg of water
Step-by-step explanation:
Find the total volume of the tank:
(80cm)*(35cm)*(40cm) = 112,000 cm^3
4/5 of this would be 89,600 cm^3
Water has a mass of 1 gram/cm^3
(1 gram/cm^3)*(89,600 cm^3) = 89,600 g of water
(89,600 g)*(1 kg/1,000 g) = 89.6 kg of water
x=1 f = 10(5.5)(1) = 55
x=2, f = 10(5.5)(2) = 110
110-55 = 55
2-1 =1
55/1 = 55
average rate of change = 55
