Answer:
x=5
Step-by-step explanation:
The area is:
A = x * y
The perimeter is:
P = 2x + 2y = 100
We clear y:
2y = 100-2x
y = 50-x
We write the area in terms of x:
A (x) = x * (50-x)
Rewriting:
A (x) = 50x-x ^ 2
Deriving:
A '(x) = 50-2x
We equal zero and clear x:
50-2x = 0
x = 50/2
x = 25
Then, the other dimension is given by:
y = 50-x
y = 50-25
y = 25
Therefore, the largest area is:
A = (25) * (25)
A = 625 feet ^ 2
Answer:
the largest area you can enclose using the materials you have is:
A = 625 feet ^ 2
Answer:
.05
Step-by-step explanation:
you divide 5 by 100 which makes it .05
The scale factor is 7.5 because if you divide 30 by 4 and 45 by 6, it is 7.5.
So to find the actual measurement of Harper's bedroom, you multiply 1.2 by 7.5, that would be 9 feet wide, and 1.6 by 7.5, that would be 12 feet long.
9 feet wide, 12 feet long
Answer:
10 units
Step-by-step explanation: Using a coordinate plane, draw a right triangle so the legs are 6 and 8 units long, then use your formula A to the second power + B to the second power equals C to the second power.
