Answer:
A backyard farmer wants to enclose a rectangular space for a new garden. She has purchased 80 feet of wire fencing to enclose 3 sides, and will put the 4th side against the backyard fence. Find a formula for the area enclosed by the fence if the sides of fencing perpendicular to the existing fence have length
L.
In a scenario like this involving geometry, it is often helpful to draw a picture. It might also be helpful to introduce a temporary variable,
W, to represent the side of fencing parallel to the 4th side or backyard fence.
Since we know we only have 80 feet of fence available, we know that
L + W + L = 80, or more simply, 2L + W = 80. This allows us to represent the width, W, in terms of L: W = 80 – 2L
Now we are ready to write an equation for the area the fence encloses. We know the area of a rectangle is length multiplied by width, so
A = LW = L(80 – 2L)
A(L) = 80L – 2L2
This formula represents the area of the fence in terms of the variable length
L.

As per the problem,
Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.
We have been asked to find , which expression can be used?
As per the distributive property , we know that
Now apply this on the given expression we get
Hence the expression , which can be used is 17(69+31)

Step-by-step explanation:
Given that Jason has a chance for getting oil as 45%
THe kit he buys show accurate result with 80% probability
Let A1- Event that the land has oil
A2 - Event that the land has no oil
B- The test gives negative result
A1 and A2 are mutually exclusive and exhaustive
P(A1) = 0.45 and P(A2) =0.55
Hence we can use Baye theorem
Then P(B) = P(A1B)+P(A2B)=
Reqd prob =P(A1/B) =
Answer:
The fraction of the book Omarion read over the weekend=3/5
Step-by-step explanation:
Step 1
Determine the initial number of pages in a book that's remaining as follows;
Initial number of pages remaining=9/10 of the book
Step 2
Determine fraction of the book read over the weekend as follows;
fraction read over the weekend=fraction of the remaining read×initial number of remaining pages read
where;
fraction of the remaining read=2/3
initial number of remaining pages read=9/10
replacing;
fraction read over the weekend=(2/3)×(9/10)=3/5
The fraction of the book Omarion read over the weekend=3/5
