3) A linear equation to represent this would be 205 = 10x + b
x is days passed, which is 10, and b is the original amount.
10 times 10 is 100, so we now have 205 = 100 + b
Subtract 100 from both sides to get 105 = b, which is the starting amount.
The rate of change is 10, however many cans brought per day.
4) So it appears that for every 5 minutes she frosts 4 cupcakes, which means the rate of change is 4/5 using rise over run.
Subtract 4 from 28 to get the starting amount 5 minutes earlier.
The starting amount of frosted cupcakes is 24.
5) Every 3 months he gets 9 more CDS. So, every month he gets 3 new CDs.
That means the slope is 3.
Subtract 9 from 18 to get the starting amount.
The starting amount of CDs is 9.
Hope this helps!
Answer:
d. sugar crystals with stirring at 15°C
Step-by-step explanation:
- The rate of the dissolving of the sugar depends upon the quantity of sugar added, the temperature of the liquid, and the movement of the particles.
- According to the given question, the sugar crystals added in the cup of water and is stirred at the temperature of 15 degrees Celsius, the sugar will dissolve the fastest.
- In this case, the sugar is in crystal form and not in the cubes, there is a motion by stirring them and the temperature is warm.

Answer:
n = 61 costumers
Step-by-step explanation:
For calculating the number of costumers he should sample we use the next equation:
Where E is the error that we are prepared to accept, in this case E = 0.15
How we don't know the value of p, we can estimate it like p = 0.5
∝ = 1-0.98 = 0.02
1-∝/2 = 0.99
n = 60.32 costumers
n ≈ 61 costumers
