Answer: Graph A
Step-by-step explanation: The line drops, crosses over the y axis, then stays at that constant level
Answer:
y/x = 2.5
Step-by-step explanation:
y ∝ x
change ∝ to = by adding constant k or c
y = kx
Divide both sides by x
y/x = k, also k = y/x
Input the values
k = (7 1/2)/3. Change 7 1/2 to improper fraction to give 15/2
k = (15/2)/3
k =
÷ 3
Change the division sign to multiplication which will change 3 to its inverse(1/3)
k =
× 
k = 
Divide the numerator and denominator by 3 to get 5/2
k = 5/2
From y/x = k,input k into the eqn
y/x = 5/2
y/x = 2.5
Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
Answer:
2 hours 30 minutes
Step-by-step explanation:
210 - 30 = 190
190 / 75 = 2.5
Sorry if I'm wrong.
