Answer:
Recursive formula: 
Explicit formula: 
Step-by-step explanation:
Let n be the number of week, 
be the number of albums Pam has on week n.
Every week she buys 3 new albums to keep her collection current, then
{The number of albums Pam has on week n is the number of albums Pam has previous week increased by 3}
This is a recursive formula.
Suppose initially Pam has 0 albums. Then the first week she has 3 albums, the third week - 6 albums and so on. Mathematically
The explicit formula is
All you need to do is divide the number of guests (128) by how many guests can be seated at a table (8) and that will give you how many tables will be needed:
128/8=16
16 tables will be needed to seat 128 guests.
Answer:
9 ft
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
8 in x
-------- = -------
7 in 8 ft
Cross-multiplying, we get: 64 in-ft = 7x in
Dividing both sides by 7 in, we get:
64 in-ft
------------ = 9 ft (rounded down from 9.143 ft)
7 in
117miles/180minutes ~~ 117miles/3hours ~~ miles/hour(mph)
117miles ÷ 3hours = 39miles/hour or 39 miles per hour.
(<em>Speed=x</em>) Speed needed is: x ≥ 39mph.
