Answer:
Step-by-step explanation:
480 = 100%
72 = ? you can find it doing (72(100))/480
72(100)= 7200
7200/480= 15
the answer is 15%
have a nice day :)
Answer:
The Answer is 18 then 25 then 21 then 20
Step-by-step explanation:
Hey there! :)
In order to the find the missing side length of this triangle, we'll need to use the Pythagorean Theorem!
That equation is : a² + b² = c²
a = adjacent side
b = long side of rectangle
c = hypotenuse
We're already given the values of both a & c, so let's plug everything in!
a² + b² = c² → a = 10 , b = ? , c = 20
(10²) + b² = (20²)
Simplify.
100 + b² = 400
Subtract 100 from both sides.
b² = 400 - 100
Simplify.
b² = 300
Get the square root of b² & 300.

Simplify!
b = 17.3
So, the missing side length is the first answer choice : 17.3~Hope I helped!~

Using the volume of the rectangular prism, it is found that it takes 7 hours to fill the pool.
<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism of dimensions l, w and h is given by the multiplication of it's dimensions, that is:
V = lwh.
In this problem, the dimensions in meters are: l = 7, w = 3, h = 0.75. Hence, the volume in cubic meters is:
V = lwh = 7(3)(0.75) = 15.75.
It fill 2.25 cubic meters per hour, hence, for 15.75 cubic meters, the time taken is:
15.75/2.25 = 7 hours.
