Answer:
¹/15
Step-by-step explanation:
Area of the rug = s²
Where s = 2 m
Area of the rug = 2² = 4 m²
Area of the rectangular carpet = length × width
Where,
Length = 12 m
Width = 5 m
Area = 12 × 5 = 60 m²
Fraction of the carpet covered by the rug = area of the rug ÷ area of the carpet = 4/60 = ¹/15
Answer:
first one is a and the second one is c
Answer:


Step-by-step explanation:
Given

Solving (a): Write as inverse function

Represent a(d) as y

Swap positions of d and y

Make y the subject


Replace y with a'(d)

Prove that a(d) and a'(d) are inverse functions
and 
To do this, we prove that:

Solving for 

Substitute
for d in 




Solving for: 

Substitute 5d - 3 for d in 

Add fractions



Hence:

Answer:
The answer is four months
Step-by-step explanation:
You have a starting cost of $50 with a $20 fee every month
OR
You have a starting cost of $30 with a $25 fee every month
Start: $50 ($20 per month)
M1 = $70, M2 = $90, M3 = $110, M4 = $130
Start: $30 ($25 per month)
M1 = $55, M2 = $80, M3 = $105, M4 = $130
In conclusion, the prices of the two will match at Month 4
