If it doubles every 4 hours, in 12 hours you will have 3 doublings.
2 * 2 * 2 = 8
90*8 = 720 pounds of algae
Answer:
40%.
Step-by-step explanation:
We have been given that the owners of Expo Company John Smith and Susan Jones invested $240,000 and $160,000 into the business respectively. We are asked to find the percentage of business owned by Susan.
Let us figure out total money invested in business by adding the money invested by John Smith and Susan Jones.


Now we will find $160,000 is what percent of $400,000.



Therefore, Susan owns 40% of the business.
Answer:
g(x)=(x+7)^2-3
Step-by-step explanation:
Given:
f(x)= x^2
Now we have to translate f(x) 7 units to the left and 3 units down to form the function g(x).
As per the rules of translation
when any parent function, in given case f(x)=x^2, is translated to 'a' units to the left then 'a' is added to the value of x. thus making f(x+a)
Also when the parent function is translated any 'a' units down then 'a' is subtracted from the value of function. thus making f(x)-a
Translating f(x), 7 units to the left
f(x+7)= (x+7)^2
Translating f(x+7), 3 units down
f(x+7)-3 = (x+7)^2-3
Hence new function g(x)=(x+7)^2-3!
Answer:

Step-by-step explanation:
Let the length and breadth be 5x and 4x respectively.
Area of rectangular field = 18000 m²
<u>Finding </u><u>the </u><u>value </u><u>of </u><u>x</u>
Area of rectangle = 
Plug the values
⇒
Calculate the product
⇒
Swap the sides of the equation
⇒
Divide both sides of the equation by 20
⇒
Calculate
⇒
Squaring on both sides
⇒
<u>Replacing the value of x in order to find the value of length and breadth</u>
Length = 
Breadth = 
<u>Finding </u><u>the </u><u>perimeter</u><u> </u><u>of </u><u>the </u><u>rectangular</u><u> </u><u>field</u>
Perimeter of rectangle = 
plug the values
⇒
Distribute 2 through the parentheses
⇒
Add the numbers
⇒
