5÷3=1.7
Donna used about 1.7 tubes of glitter for each poster.
I'm pretty sure this is it because when you divide this you get 1.6 repeating and you get 1.7 when you round it.

Answer:
1330 rounds of meetings
Step-by-step explanation:
You have a total of 21 people, and they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does <em>not</em> matter.
Formula for combination:
ₙCᵣ =
where <em>n</em> is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).
We plug in and get:
->
-> 1330 different meetings for everyone to meet with each other in groups of 3.
Answer:
(a) d dt y7=7Y^6
(b) d dt y3e4t=3Y^2e^{4t}+4Y^3e^{4t}
(c) d dt t7 cos(y6)=7t^6 cos(y6)+t^7(-sin(y^6))·6Y^5
Step-by-step explanation:
We calculate the following derivatives. Since these are complex derivatives, we also calculate the formula for complex derivatives. We use Y for the derivative of y . Therefore, we calculate and we get
(a) d dt y7=7Y^6
(b) d dt y3e4t=3Y^2e^{4t}+4Y^3e^{4t}
(c) d dt t7 cos(y6)=7t^6 cos(y6)+t^7(-sin(y^6))·6Y^5
