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.
Answer:
x = 3.51
Step-by-step explanation:
Since, formula to determine the area f a triangle is,
Area =
8 =
16 = x(3x - 7) + 1(3x - 7)
16 = 3x² - 7x + 3x - 7
16 = 3x² - 4x - 7
0 = 3x² - 4x - 23
3x²- 4x - 23 = 0
By quadratic formula,
x =
x =
x =
x =
x = 3.51, -2.18
But the length of sides can't be negative.
Therefore, x = 3.51 will be the answer.
