The answer is 9 fish.
The density (d) is the number of units(n) per volume (V):
d = n/V We know: d = 0.3 fish/ft³. V = 30 ft³ n = ? d = n/V n = d * V n = 0.3 fish/ft³ * 30 ft³ n = 9 fish
You would use the Pythagorean theorem A squared plus B squared equals C squared so you would for example do 5 squared plus 6 squared equals 8 squared so then in your calculator you would put five squared +6 squared see what that equals then do another thing and put eight squared and if it equal each other than it can make a right angle
We know that the opposite is the additive inverse.
For example, 8+(−8)=0 where 0 is the identity for addition.
Given that we have to compute the sum of 5x+20 and the opposite.
Given
5x+20
opposite of 5x+20 = -(5x+20)
so
The sum of 5x+20 and the opposite:
5x+20 + -(5x+20)
Distribute the Negative Sign

Therefore, the sum of 5x+20 and the opposite is: 0
Thus, the equivalent expression is:
Hello from MrBillDoesMath!
Answer: 70%
Discussion:
Goal = 5000
Amount raised = 3500
Percent of goal reached = ( 3500/5000) * 100 =
0.7 * 100 = 70
Thank you,
