Answer:
Step-by-step explanation:
we know that
The area of the backyard pool to be resurfaced is equal to the area of the base plus the area of its four lateral sides.
so
where
B is the area of the base
P is the perimeter of the base
H is the depth of the pool
<em>Find the area of the base B</em>
substitute the given values
<em>Find the perimeter of the base P</em>
substitute the given values
we have
<em>Find the area of the backyard pool to be resurfaced</em>
substitute the values
Answer:
75%=x-125
90%=x+250
subtract the second from the first
15%=375
100%=?
100%×375/15
100%=2500marked price is 2500
2500+250=2750
90%=2750
100%=?
cost price=3055.56
Answer:
For a better understanding of the solution provided here, please find the diagram attached.
In the diagram, ABCD is the room.
AC is the diagonal whose length is 18.79 inches.
The length of wall AB is 17 inches.
From the given information, we have to determine the length of the BC, which is depicted a , because for the room to be a square, the length of the wall AB must be equal to the length of the wall BC.
Thus, inches
and hence, the given room is not a square.
Step-by-step explanation:
5 ft + 12 ft = 17 ft
<span>9 in + 3 in = 12 in = 1 ft </span>
<span>17 ft + 1 ft = 18 ft
