Answer:
$12.99 for 5 pounds is a better deal
Step-by-step explanation:
for the first case
a 5 lb bag costs $12.00
the unit price (i.e dollars per pound) for this is :
unit price = $12 / 5 lb = $2.40 per pound
for the second case,
a 12 lb bag costs $31.99
similarly, the unit price for this case is :
unit price = $31.99 / 12 lb = $2.67per pound
if we compare the 2 unit price, it is clear that $2.40 per pound is a better deal than $2.67 per pound, hence $12.99 for 5 pounds is a better deal
Hope this helps!

Answer:
64°
Step-by-step explanation:
Check the attachment for the diagram. Since the triangle has one of its angle as 90°, it is a right angled triangle.
Using the SOH CAH TOA trigonometry ratios:
Since ∠P is opposite to side QR,
QR = opposite side = 8ft
RP = adjacent side = 3.9ft
According to TOA
Tan∠P = Opposite/Adjacent = QR/RP
Tan∠P = 8/3.9
Tan∠P = 2.05
∠P = arctan 2.051
∠P = 64°
Relations are functions if every input has exactly one output
So, the first on is a function because each x value has one y value. Meaning, for example, (3,2), 3 is the x value, which is the input, and 2 is the y value which is the output. But within that set of relations, 3 only has one output which is 2.
The second one is not a function because 2 has 2 outputs. (2,3) and (2,5). 2 has an output of 3 and 5. Every input can only have one output. So this isn't a function
The third one isn't a function because 6 has two outputs. (6,3) and (6,6). 6 has two outputs of 3 and 6, so it's not a function
The last one isn't a function either because 6 has two outputs. (6,8) and (6,4). 6 has the outputs of 8 and 4. So, it is not a function
Hope that helps :)
