Answer:
30cm
Step-by-step explanation:
Assuming that the thickness of the books is 2cm (This is a reasonable assumption, as books are almost always longer and wider than they are thick, and assuming that the books are stacked flat on top of one another, faces up or down, and not sideways, the question becomes 'What is the height of 15 books stacked on top of one another, if each book is 2cm thick?' The answer to this question is 15*2 or 30.
Answer:
If there was another dog whose weight was greater than or less than 12.
Step-by-step explanation:
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 4
When we add 4 to the data set we have:
184 ÷ 16 = 11.5
This changed the median.
12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 28
When we add 28 to the data set we have:
208 ÷ 16 = 13
This also changed the median.
Answer: k=9
reasoning: just plug in 1 for x and 1 for y
Here you go the answer is 110
Answer:
Step-by-step explanation:
Let Q(t) be the first substance at time t. We know that the rate of change is directly proportional to 
.
Hence we can write it as:
<u>Step 1: Integrating the function to form an equation:</u>
<u />
----------------------------------------------- equation (1)
<u>Step 2: Substitute the value Q(0) = 45 in equation 1 to find value of C.</u>
<u />
---------------------------------------------- equation (2)
<u>Step 3: Substitute the value Q(1) = 10 in equation 2 to find the value of k.</u>
<u />
<u>Step 4: Form the equation and simplify it.</u>
<u />
<u />
<u />
<u>Step 5: To find the amount of substance after 2 hours, we substitute the value of t with 2.</u>
<u />
<u />
<u />
The amount of substance after 2 hours is 5.63 grams.
