Answer:
The dimensions of the yard are W=20ft and L=40ft.
Step-by-step explanation:
Let be:
W: width of the yard.
L:length.
Now, we can write the equation of that relates length and width:
(Equation #1)
The area of the yard can be expressed as (using equation #1 into #2):
(Equation #2)
Since the Area of the yard is 
, then equation #2 turns into:
Now, we rearrange this equation:
We can divide the equation by 5 :
We need to find the solution for this quadratic. Let's find the factors of 160 that multiplied yields -160 and added yields -12. Let's choose -20 and 8, since 
and 
. The equation factorised looks like this:
Therefore the possible solutions are W=20 and W=-8. We discard W=-8 since width must be a positive number. To find the length, we substitute the value of W in equation #1:
Therefore, the dimensions of the yard are W=20ft and L=40ft.
Answer: 0 -4 and -8
Step-by-step explanation:
If you divide -12/-3=4 and 4/4=1
The answer is 93. The angle looks really close to 90 and 93 is the closest.
Answer:
When two atoms have shared electrons, it is not distinguishable from what atom they are because they are shared in the same orbit, it is called a covalent bond.
Step-by-step explanation:
Atoms in a covalent bond share one or more electrons in the last of their orbitals, the number of electrons in the last orbital will depend on the element in question.
Hi, first, the grammar has been a bit confusing, but i think i have it. the question is that one group has 28 baseball cards and another has 68, right? in order to tell how much each person could have received, we first have to know how many people there were and divide the numbers of cards by that. since you never specified the number of people in the groups, i can't solve it completely. all together you have 96 cards. i hope this helps.
