550+450-120+720=1,600
720/1,600*100%
=720/160%
=45%
therefore, 45% of new balance
Answer:
68
Step-by-step explanation:
im not too sure
Let the lenght perpendicular to street = x
Means lenght two sides will be x and x
Another side of retangle will be = 256 - 2x
Area of rectangle will be= A = x * (256-2x) = 256 x - 2 x^2
For maximum area, dA/dx = 0
d/dx (256 x - 2 x^2) = 0
256 - 4 x = 0
4 x = 256
x = 64 feet
Means one side is 64 feet
Another side will be = 256 - 2 * 64 = 128
Now we have two sides of rectangle 64 and 128
Area = 128 * 64 = 8192 square feet : Answer
Hope it will help :)
Answer:
11 small frames, 5 large frames
Step-by-step explanation:
small: x
large : y
x + y = 16
4x + 14y = 114
Multiply first equation by 4 and subtract.
4x + 4y = 64
-(4x + 14y = 114)
-10y = -50
y = 5
Substitute y into the first equation.
x + 5 = 16
x = 11
Do you mean the cost per ounce?
Then that would be $0.1496, or rounded to the nearest cent, 15 cents a ounce.
