Answer:
The length of the fence is 22.5ft and the width of the fence is 7.5ft.
Explanation:
To solve this problem we will turn this question into an equation.
The equation for the perimeter of a rectangle is 2l + 2w = perimeter.
In the question we were given the perimeter so we can go ahead and plug this in.
2l + 2w = 60
In the question we are also told that the fence is 3 times as long as it is wide. This means that 1l = 3w. We can now subsitute l for 3w so that we only have one variable.
2(3w) + 2w = 60
Now we can simply use algebra to solve for w.
6w + 2w = 60
8w = 60
w = 7.5
Now that we know the value of w we can find the value of l since we know 1l = 3w.
l = 3w
l = 3(7.5)
l = 22.5
The length of the fence is 22.5ft and the width of the fence is 7.5ft.
Answer:
The regrouping of the two systems affect the components because they either don't work together or other...
Explanation:
Its not always accurate because you dont know what they could have done to it before they try to sell it
Answer:
False
Explanation:
The Avogadro's number is not used to determine the number of subatomic particles in an atom.
Subatomic particles of an atom are the protons, neutrons and electrons.
The protons are the positively charged particles in an atom
Neutrons do not carry any charges
Electrons carry negative charges.
The number of protons, neutrons and electrons in an atom are experimentally determine using spectrometric techniques.
Yes! since its clear, <span>due to formation of ammonium hydroxide in water.</span>
