Answer:
5029
Step-by-step explanation:
There is a common difference between consecutive terms, that is
d = - 201 - (- 215) = - 187 - (- 201) = - 173 - (- 187) = 14
This indicates the sequence is arithmetic with sum to n term
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 215 and d = 14 , then
= [ (2 × - 215) + (46 × 14) ]
= 23.5 (- 430 + 644)
= 23.5 × 214
= 5029
They both saw the same amount because 6+3 = 9 and 3+6 = 9
We know that the volume of a sphere is:

where
r

Step-by-step explanation:
Answer:
Better deal at Store B.
Step-by-step explanation:
The key to understanding this problem lies in recognizing that 16 ox = 1 lb, which leads to 64 oz = 4 lb.
Find and compare the two unit costs:
Store A:
$11.99
---------- = $0.20/oz
60 oz
Store B:
$11.99
------------ = $0.19/oz
64 oz
The 4-lb bag available at Store B has the lower unit cost and is a better deal there.
