A school cafeteria sold 1,280 slices of pizza the first week,640 the second week,and 320 the third week.if this pattern continue
mario62 [17]
So we have 1280,640,320,... 
This is a geometric sequence with the first term, a_{1} =1280. To find the common ratio r, we are going to divide any current term by a previous one: r= \frac{640}{1280} =(0.5)

Remember that the main formula of a geometric sequence is:
a_{n} = a_{1} r^{n-1}
Where a_{n} is the nth term (in our case 40), a_{1} is the first term (in our case 1280), r is the common ratio (0.5), and n is the position of the term in the sequence (in our case our weeks)

Now we can replace the values to get:
40=1280(0.5)^{n-1}
(0.5)^{n-1} = \frac{40}{1280}
(0.5)^{n-1} =0.03125
Since our variable, n, is the exponent, we are going to use logarithms to bring it down:
ln(0.5)^{n-1} =ln(0.03125)
(n-1)ln(0.5)=ln(0.03125)
The only thing left now is solving for n to find our week:
n-1= \frac{ln(0.03125)}{ln(0.5)}
n-1=5
n=6

We can conclude that in the sixth week the cafeteria will sell 40 slices of pizza.

Which equation shows 4n=2(t-3) solves for t?
noname [10]

Answer:

t = 2n + 3

Step-by-step explanation:

Given

4n = 2(t - 3) ← divide both sides by 2

2n = t - 3 ( add 3 to both sides )

2n + 3 = t
