So chance to get a black pen: 4/10=2/5
Chance to get a red pen: 1/10
Chance for the two happened at the same time
2/5 * 1/10 = 2/50=1/25
I think... I’m not very sure though
Answer:
6.75 pounds
Step-by-step explanation:
This question is of direct variation. We will use x as our answer. 8 is 2/3 of 12, so 4.5 should be 2/3 of x. We can now make an equation.

In order to solve the equation, we multiply both sides by the reciprocal of 2/3, which is 3/2.
* stands for multiplication
From solving our equation, we get 6.75. We can't forget the units, so the answer is 6.75 pounds.
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:
