Answer:
PetSmart is offering the best deal
Step-by-step explanation
For Gristede's we get 18 and divide it by 12 which would give us $1.50 per can
For PetSmart we get 26 and divide it by 20 which would give us $1.30 per can
The correct answer is 0.99kg/L
Explanation:
To find the density, the first step is to convert the weight (mass) and the volume into the appropriate units.
The volume is 8.5 gallons and this needs to be converted to litters. In this case, multiply the volume in gallons by 3.785 because each gallon contains 3.785 liters.
8.5 x 3.785 = 32.1725 liters
The mass is 70 pounds and this needs to be converted to kilos. In this case, divide the pounds by 2.204 considering each kilo contains 2.204 pounds.
70 ÷ 2.2046 = 31.751 kilos
Now, find the density by dividing the mass into the volume.
Density= 31.751 kg ÷ 32.1725 L
Density = 0.98 kg/L
This means the density is 0.9.868 kg/L and this can be rounded as 0.99 kg/L
Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 8 when x = 20
k =
=
= - 
y = -
x ← equation of variation
When x = - 4, then
y = -
× - 4 =
