Answer:
<em>4 shelves</em>
Step-by-step explanation:
First you will have to subtract the one she keeps by her bed.
27 - 1 = 26 to be put on a shelf.
To find the least number of shelves needed, you will divided the total left by eight:
26 ÷ 8 = 3.25
She can fill 3 shelves completely and still have books left over. So she needs at least 4 shelves!

Answer:
(i) The value of<em> m</em> when t = 30 is 13.2
(ii) The value of <em>t</em> when the mass is half of its value at t=0 is 34.7
(iii) The rate of the mass when t=50 is -0.18
Step-by-step explanation:
(i) The <em>m</em> value when t = 30 is:

Then, the value of<em> m</em> when t = 30 is 13.2
(ii) The value of the mass when t=0 is:
Now, the value of <em>t </em>is:


Hence, the value of <em>t</em> when the mass is half of its value at t=0 is 34.7
(iii) Finally, the rate at which the mass is decreasing when t=50 is:

Therefore, the rate of the mass when t=50 is -0.18.
I hope it helps you!
I will give you an example for question 1. There are two right angels on your paper so what you need to do is x out the two right angels and multiply base x hieght. and I hope you get it correct
