1. The formula for the area of a rectangle is:
A=LxW
L: The lenght of the rectangle (L=2W).
W: The width of the rectangle.
2. Let's substitute L=2W into the formula A=LxW:
A=LxW
A=2WxW
A=2W²
3. When we clear "W", we obtain:
W²=A/2
W=√(A/2)
4. We already know the value of "A", so:
W=√(50 ft²/2)
W=√(25 ft²)
W=5 ft
5. Now, we must substitute the value of "W", into L=2W:
L=2W
L=2(5 ft)
L=10 ft
6. The perimeter of a rectangle is:
P=2L+2W
7. We know the value of "L" and "W", therefore:
P=(2x10 ft)+(2x5 ft)
P=20 ft+10 ft
P=30 ft
W<span>hat is the perimeter of the porch?
</span>
The answer is: 30 ft
Answer: 
Step-by-step explanation:
Given: A graphics company charges $50 per hour to create a logo plus $250 for the ownership rights of the logo.
Let x be the number of hours , then the total cost to create the logo plus is given by :-

A private contractor charges $75 per hour to develop a logo plus a $100 supply fee.
The total cost to develop logo plus is given by :-

The equation to represent the costs would be the same is given by :_

Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
$1,980
Step-by-step explanation:
We can use the simple interest formula for this:

<em>P = initial balance</em>
<em>r = annual interest rate</em>
<em>t = time</em>
<em />
First, change 2% into its decimal form:
2% ->
-> 0.02
Now, lets plug the values into the equation:


The account balance after 5 years is $1,980
<span>I'm pretty sure that the solution looks like this </span>

. But Also you can use this formula (r-k+1 C r). You will get 18C3.
