Answer:
A unit rate is the rate of change in a relationship where the rate is per 1.
The rate of change is the ratio between the x and y (or input and output) values in a relationship. Another term for the rate of change for proportional relationships is the constant of proportionality.
If the rate of change is yx, then so is the constant of proportionality. To simplify things, we set yx=k, where k represents the constant of proportionality.
If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation. In a direct variation equation, y varies directly with x. When x increases or decreases, y also increases or decreases by the same proportion.
To find y in a direct variation equation, multiply x by the constant of proportionality, k.
For example: Given the relationship y=7x, the constant of proportionality k=7, so if x=3, then y=3×7 or 21.
Given the same relationship, if x=7, then y=7×7, or 49.
Step-by-step explanation:
Answer:
2. 3.913 kg (3 dp)
3. light cream
4. 240 CoffeeStops
5. 7 CoffeeStops per square mile
6. 2,861 cups of coffee each day
Step-by-step explanation:
Given:
- Skim milk density at 20 °C = 1.033 kg/l
- Light cream density at 20 °C = 1.012 kg/l
- 1 liter = 0.264 gallons
<u>Question 2</u>

Therefore, the mass of 1 gallon of skim milk is 3.913 kg (3 dp)
---------------------------------------------------------------------------------------------
<u>Question 3</u>
Given:
- Volume of liquid = 9 liters
- Mass of liquid = 9.108 kg

Therefore, the container holds light cream.
---------------------------------------------------------------------------------------------
<u>Question 4</u>
Given:
- 15 CoffeeStops per 100,000 people
- Population of Manhattan ≈ 1,602,000 people

Therefore, there are 240 CoffeeStops.
---------------------------------------------------------------------------------------------
<u>Question 5</u>
Given
- Manhattan ≈ 34 square miles

Therefore, the density of CoffeeStops is 7 per square mile.
---------------------------------------------------------------------------------------------
<u>Question 6</u>
Given:
- Each person buys 3 cups of coffee per week


Therefore, each Manhattan CoffeeStop serves approximately 2,861 cups of coffee each day.
150% of 51 is 34. So your answer is 51
Answer:
the answer would be it is approximately <u>4</u><u>3</u><u>.</u><u>8</u><u>5</u>
<u>(</u><u>did </u><u>addition</u><u>)</u>
I think it's C, because first you multiply all the sides which is 112 then multiply by 3 and the answer it's 336 if I'm correct.
