Let 
x---------> the length side of rectangle
y---------> the width side of rectangle

we know that
x=2y-----> equation 1
area=x*y-------> 28800=x*y------> equation 2
substitute 1 in 2

28800=[2y]*y-----> 28800=2y²-------> y²=14400------> y=120 m
x=2*y----> x=2*120------> x=240 m

the answer is
the length side of rectangle is 240 m
 the width side of rectangle is 120 m

Q1: Rearranging the last of the offered equations, you find

... selling price = overhead/(overhead percent) = $65.34/0.45 = $145.20

Then the net profit is

... net profit = selling price - cost - overhead = $145.20 - 49.32 - 65.34 = $30.54

Q2: Using the same net profit equation, you have

... net profit = selling price - cost - 0.47×selling price = 0.53×selling price - cost

... net profit = 0.53×$3,816,981.10 - 1,723,000.00 = $300,000

Q3: The applicable equation is

... net profit = markup - overhead

This matches selection ...

... B) Net Profit = $30.00 - 0.4 X Selling Price

Ella threw 5 grams of salt into 20 grams of water. She made ___ grams of ___% salt solution.
erastovalidia [21]
When we make a solution, the solute doesn't go away. All the solute we use stays in the solution it only dissolve in the solution.

The total mass of solution is always equal to the mass of solvent added to the mass of solute.

Therefore 5gram + 20 gram = 25 gram of solution.

5/25×100= 20%

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: Volume\:of\:sphere=\frac{4}{3}\pi r^3

Putting value of radius and π and finding volume:

Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in

So, Volume of sphere = 4.186 cubic inches
