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

The reasonable domain has a minimum value.
The reasonable range has a minimum value of 30,000.
The reasonable range has an implied, but unknown, maximum value.
Step-by-step explanation:
1. Years cannot be anything below 0.
2. The domain includes 0 because the answer can be the initial value.
3. 30,000 is the initial value and is the minimum solution.
4. The range has a minimal of 30,000.
5. Logically, we know city populations cant be numbers like a billion but we prove that mathematically.
Answer:
4m² + 6mn - 2n²
Step-by-step explanation:
Complete question is;
The function f(x) = (9/5)x + 32 converts temperatures from x degrees in Celsius
to y degree in Fahrenheit. The function g(x) = (5/9)(x − 32) converts temperatures from x degrees in Fahrenheit to y degrees in Celsius.
a. Find (f o g) (x)
b. (g o f) (x)
Answer:
A) x
B) x
Step-by-step explanation:
A) f(x) = (9/5)x + 32
g(x) = (5/9)(x − 32)
Thus;
(f o g) (x) = (9/5)(g(x)) + 32
This gives;
(9/5)((5/9)(x − 32)) + 32 = x - 32 + 32 = x
B) (g o f) (x) = (5/9)((f(x)) − 32)
This gives;
(5/9)((9/5)x + 32 - 32) = x
