Answer:
7 cards.
Step-by-step explanation:
60-39.5=20.5, that's what he has left if he buys 5 cards.
so, if you buy 2 more cards, that would be 18 dollars so 20.5-18=2.5
5 cards+ 2 cards= 7 cards.
He still hzs 2.5 dollars left
X< - 1/8 let me know if Uu need work
You multiply 86 by 42.5 because each board is 42.5 and there are 86 boards.
Answer:
Step-by-step explanation:
perimeter of rectangle=2(length+width)
=2(70+65)
=2*135
=270 feet
If you visualize the problem, there are two concentric circles, the pool, and the pool plus the walkway. So, we have to subtract the area of these two concentric circles to find the walkway.
Bigger circle: Pool plus walkway
----------------------------------
diameter = 18 + 4(2) -- this is because there is 2 ft of walkway at each far end
diameter = 26 ft
Area = pi*(26/2)^2
Area = 530.93 ft2
Smaller circle:pool
---------------------
diameter = 18 ft
Area = pi*(8/2)^2
Area = 50.27 ft2
Area of walkway
----------------
A = 530.93 - 50.27
A = 480.66 ft2
Then the cost would be
Cost = $4.25 * 480.66
Cost = $2,042.81
