Hello!</h2>
The answer is:
The correct option is the third option;
<h2>
Why?</h2>
To find which of the options expresses the intersection of the three days as an inequality in terms of temperature "t" we need to find an inequality which starts at the lowest temperature (greater or equal) and finish at the highest temperature (less or equal).
So, we have that the lowest temperature is -23°F and the highest temperature is 50°F, there are two options for that range, but we need to consider that the temperature will range from -23° to 50°, so, the correct option is the third option;
We can see that the inequality express that the temperature will range from -23°F being greater or equal than that, to 50°F being less or equal than that.
Have a nice day!

Answer:
length of the base = 9 ft
and height of the shed = 7 ft
Step-by-step explanation:
given data
volume = 567 cubic feet
base costs = $2 per square foot
roof costs = $5 per square foot
sides costs $4.50 per square foot
solution
we take here length of the base = x ft
and height of the shed = y ft
so Volume will be express as
volume = x²× y
567 = x² × y
y = 
and
we know cost of material is express as here
cost of material = cost of base + cost top + cost 4 side ..................1
put here value
cost = x²(2) + x²(5) + 4xy (4.5)
cost = 7x² + 18xy
put here y value
cost = 7x² + 18 x ( )
differentiate and we get
C' = 14x - 
we put here C' = 0 and we get
14x - = 0
solve it we get
x = 9 ft
and
y = 
y = 7 ft

Answer:
Step-by-step explanation:
14 + 5t > = 49 (thats a greater then or equal sign)
5t > = 49 - 14
5t > = 35
t > = 35/5
t > = 7 <===
