for number 5, you take the area of the area of the fountain, which is pi * radius squared. this is equivalent to 3.14 * 4^2. then to simplify I made it 3.14 times 16 and then got the answer of 50.24. Then you take the area of the fountain plus the path, which makes the diameter 9.5 divide that by 2 to get the radius, which is 4.75. pi * 4.75^2 is about 70.85. then you subtract the two(70.85-50.24) to get 20.61. since its 10 dollars per square meter, you multiply 20.61 by 10 to get 206.10 dollars. That is your answer.
A fraction that is equivalent to
will have the form
, where
A and
B are equivalent and factors that are multiplied in.
The product fraction should be easily simplified using
A and
B to get the original fraction.
<em>In the case of your fraction </em>
you will need to find a fraction which is a product of this:
Answer:
kg
Step-by-step explanation:
We are given that
Volume,V=9000 L
We have to find the salt in the tank after t minutes.
Let y(t) be the amount of salt dissolved in the tank
y(0)=16
rate in-rate out
Rate in=0
Rate out=
Where
Substitute t=0 and y=16
