Answer:
Depth of the rain gutter is 8 inches
Step-by-step explanation:
Let’s assume ‘x’ is the depth of the rain gutter
Then the width of the rain gutter can be written as 16 - 2x
Cross sectional area
A = depth x width
Substitute values
A = x*(16 - 2x)
A = 16x – 2x^2
Now according to axis of symmetry for maximum area x = -b/2a
x = -16/2*(-2)
x = 4 inches depth of rain gutter, substitute the value of x to get
Width of rain gutter 16 – 2(4) = 8 inches
Area of the rain gutter for maximum water flow
A = 4 * 8
A = 32 square inch.
Answer:
d+9
Step-by-step explanation:
sum implies addition
so you would add d and 9
since d is a variable the most you can simplify is
d+9
Well when ever you're doing order of operations you always use please excuse my dear aunt sally please means parentheses ALWAYS GO FIRST Excuse means experience which if there's no parentheses exponents go first to my name is multiplication after parentheses multiplication always go first if there's no parentheses dear means division after multiplication comes division on means addition but pretty much after the multiplication parentheses and the division you complete the rest of the problem using the left to right method now the answer to this problem is
Answer:
2/5 = 3x
It takes 2/15 hours to do one task.
Step-by-step explanation
Here ...I'm not too sure about the question as you have written
P = 2 ( 1 + 6 ) and ask to solve for L ...
.So I guess the question you have written is wrong .. ...and I guess there should be L in the place of 1.
...So let me correct the question....
P = 2 ( l + 6 )
P = 2l + 12
P - 2l = 12
- 2l = 12 - P
- 2l = - P + 12
Change the sign of both side of the equation...
2l = P + 12
divide both side by the same number...
L = ( P + 12 ) ÷ 2
Calculate the product of rational numbers...
