Answer:
109,000
Step-by-step explanation:
1kg = 1000g
45 + 63 = 109
109 x 1000 = 109000
90cm^3. First, determine the area of the right triangle face, A=1/2(b*h) - 1/2(4.5*5) = 11.25cm^2. This triangle is repeated over 8cm, so we multiply the 11.25cm^2 * 8cm = 90cm^3.
Let: A = adult tickets; S = student tickets
a. 498 = 5A + 3S
118 = A + S
b. S = 118 - A
498 = 5A + 3(118 - A)
498 = 5A + 354 - 3A
498 - 354 = 2A
144 = 2A
A = 72
118 = S + A
118 = 72 + S
118 - 72 = S
S = 46
c. Therefore, there were 72 adult tickets and 46 student tickets sold.
