81 inches converted to feet is 6.75 feet
Answer:
125
Step-by-step explanation:
5 x 5 = 25
25 x 5 = 125
Answer:
bottom side (a) = 3.36 ft
lateral side (b) = 4.68 ft
Step-by-step explanation:
We have to maximize the area of the window, subject to a constraint in the perimeter of the window.
If we defined a as the bottom side, and b as the lateral side, we have the area defined as:

The restriction is that the perimeter have to be 12 ft at most:

We can express b in function of a as:

Then, the area become:

To maximize the area, we derive and equal to zero:

Then, b is:

Answer:
30
Step-by-step explanation:
Formulate:
50%×60
0.5×60
= 30
Answer:
0.3 > 0.09
Step-by-step explanation:
The comparison 0.3 > 0.09 is true.
0.3 = 0.300
0.300 > 0.009
All other options are false. They should have a less than sign instead of a greater than sign.
