Answer:
A=![8w^2+5w](https://tex.z-dn.net/?f=8w%5E2%2B5w)
Step-by-step explanation:
We are given that John is building a rectangular pen for his sheep.\
We have to complete the given equation
Let w be the width of rectangular pen
According to question
Length of pen=8w+5
We know that
Area of rectangle=![Length \times breadth](https://tex.z-dn.net/?f=Length%20%5Ctimes%20breadth)
Using the formula
Area of rectangular pen=![w(5+8w)=8w^2+5w](https://tex.z-dn.net/?f=w%285%2B8w%29%3D8w%5E2%2B5w)
Therefore, the area of rectangular pen=A=![8w^2+5w](https://tex.z-dn.net/?f=8w%5E2%2B5w)
7/9 of 3/14 is 1/6.
Tell me if I'm wrong.
Hope this helps :)
Answer: The speed of car B is 6.44 m/s
Step-by-step explanation:
Let's define:
Sa = Speed of car A.
Sb = Speed of car B.
I assume that at t = 0s, the position of car A is 0m (then at t = 0s, the position of car B is 174m)
Then we can write the positions of each car as:
Pa(t) = Sa*t
Pb(t) = Sb*t + 174m.
We also know that Sa = 2*Sb.
And we know that at t= 27s, car A passes car B.
Then at t = 27s, the positions of both cars must be the same:
Pa(27s) = Pb(27s)
Sa*27s = Sb*27s + 174m.
Now we can replace Sa by 2*Sb (from the above equation)
2*Sb*27s = Sb*27s + 174m
Now we can solve this for Sb.
2*Sb*27s - Sb*27s = 174m
Sb*27s = 174m
Sb = 174m/27s = 6.44m/s.
The speed of car B is 6.44 m/s
Answer:
$46.99
Step-by-step explanation:
Since both dresses that cost the same add up to a total price of $93.98, all you have to do is divide the total price by 2.
93.98/2=46.99
Answer:
2028
Step-by-step explanation:
The LCM of 4 and 6
Prime factors of 4 are 2*2
Prime factors of 6 are 2*3
Therefore, LCM is 2*2*3=12
Therefore, another time when elections coincide is after every 12 years
2016+12=2028
