Answer:
The cost of a school banquet is $75+30n, where n is the number of people attending.
If 53 people are attending to visit school banquet, then you have to find the value of given expression at n=53.
At n=53, the value is $(75+30·53)=$1,665.

Answer:
216000 m^3
Step-by-step explanation:
Volume of water
= length of tank x width of tank x depth of water
= 90(60)(40) m^3
= 216000 m^3
Answer:
B
Step-by-step explanation:
A. The volume of the spaceship is calculated through the equation,
V = 4πr³/3
Dividing the given diameter by 2 to get the radius will give us 13.4 ft. Substituting the known values to the equation,
V = 4π(13.4 ft)³/3 = 10078.64 ft³
b. If we let x be the number of people allowable in the spaceship, the equation that would best represent the scenario is,
1000x + 4073.5 = 10078.64
The value of x from the equation is 6.
