8^2+3^2= c^2
64+9
73 square rooted
AC = 8.5 = C
So BD has to be D
Answer:
Step-by-step explanation:
Not near enough information to know.
I ASSUME that the pool is surrounded by a walkway of constant width (w = 2 ft, from comments)
The pool shape is important as well. No mention of the shape
If the pool is circular and the walkway is 3 ft wide
the fence encloses a diameter of 110/π = 35 ft
so the diameter of the pool would be 35 - 2(3) = 29 ft.
POOL IS RECTANGULAR from comments
If the pool is square and the walkway is 2 ft wide, each side of the fence is
110 / 4 = 27.5 ft and the pool would be 27.5 - 2(2) = 23.5 ft on a side.
There are an infinite number of rectangular width and length dimensions and walkway dimensions which would result in a fence length of 110 ft.
Edit from comments
Still an infinite number of rectangular length an width dimensions for a pool with a 2 ft wide walkway around it.
Let's say that we are told the pool is 12 ft wide with 2 ft walkway.
Let L be the pool length
110 = 2(12 + 2(2)) + 2(L + 2(2))
110 = 32 + 2L + 8
70 = 2L
L = 35 ft
Answer:
<h2> The earnings will double</h2>
Step-by-step explanation:
Step one:
given data
we are told that the sales person's earnings is 4% of the sales made.
given that the sales made is $37,000 worth of furnaces.
Step two:
we want to find 4% of $37,000
=4/100*37000
=0.04*37000
=1480
hence for $37,000 the earning will be $1480.
Now suppose sales is doubled that is 37000*2= 74000
we want to find 4% of $74,000
=4/100*74000
=0.04*74000
=2960.
the earnings is $2960.
So if sales doubles the earnings will double
Since this is a right triangle, we can you the pythagorean theorem.
a^2 + b^2 = c^2
In this case,
a = 6
b = ?
c = 10
We need to substitute our values into the pythagorean theorem.
(6)^2 + b^2 = (10)^2. Reduce everything to its simplest form.
36 + b^2 = 100. Subtract 36 from both sides.
b^2 = 64. Take the square root of each side.
b = 8.
