Explanation:
ratio of two cubes: 2 : 5
Perimeter of one face of cube: 4 × side
For small cube: 4 × 2 = 8
For big cube: 4 × 5 = 20
Ratio of perimeter of one face: 8 : 20 = 2 : 5
Total surface area of cube: 6a²
For small cube: 6(2)² = 24
For big cube: 6(5)² = 150
Ratio of total surface area: 24 : 150 = 4 : 25
Volume of cube: a³
For small cube: (2)³ = 8
For big cube: (5)³ = 125
Ratio of volume: 8 : 125

Answer:
1. $46
2. C= 25+ 3r
Step-by-step explanation:
In this problem, we are going to model an equation for the cost of Ryans rides in the park
the $25 is a constant fee
while the $3 is a fee that depends on the number of rides
let the cost be C
and let the number of rides be r
How much would he have to pay if he goes on r rides?
C= 25+ 3r
How much money would Ryan have to pay in total if he goes on 7 rides?
C= 25+3(7)
C= 25+21
C= $46
All work shown, I hope that this works!
