Answer: Yes. The expression can be used to calculate how much Danielle has.
Step-by-step explanation:
The choir trip expenses are:
Train tickets = $77
Hotels = $106
Meals = $34
Total expense = $77 + $106 + $34 = $217
Since we are told that Danielle has a third of the amount needed for the trip. This means that we have to calculate 1/3 of $217 This will be:
= 1/3 × $217
= $72.33
Also, the expression (77+106+34) divided 3 shows the amount that Danielle has. Thus will be:
= (77+106+34) / 3
= 217/3
= 72.33
Answer:
ten stickers because 24 minus the 4 your friend gave you equals 20. divide that by the number of packs he bought and you get ten stickers per pack.
(10+10+4=20)

Answer:
6%
Step-by-step explanation:
A function f(x) can by approximated at and around a point, say x = a by,
f(x) = f(a) + f'(a)(x-a)
where, 
Here, volume V is a function of radius r and height h. In the 2 dimensional case, we have to take the partial derivatives.
Given,
or, 
at r = 1.55 m and h = 6.6 m
Therefore, 
Also, 
Hence, maximum error is given by,
= 6%
