You have 80 pieces of fabric to make a wall hanging. Each piece of fabric is a square with a side length of 5 inches. You use as

tensa zangetsu [6.8K]

Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.

HELP ME PLEASE!! If y varies directly as x, and k = 12. Find x when y = 6.

zaharov [31]

Formula: Y=kx or y=ax or Y/x=a

K=12 k is also the slope!
Slope=12
Y=6
So If you plug in these values you get:
6=12x

Answer:
X=0.5 or 1/5

The sculpture consists of five identical prisms. JD says the surface area of the sculpture is 44 times the surface area of one p

larisa86 [58]

The complete question in the attached figure

we know that
(see the attached figure n 2 to understand the problem)
[the surface area of one prism]=2*[x*x]+2*[x*y]+2*[x*y]----> 2x²+4xy
[the surface area of the sculpture]=2*[5*x*y]+2*[3*x*x]+2*[3*x*y]--> 6x²+16xy

now
JD says the surface area of the sculpture is 4 times the surface area of one prism
[the surface area of the sculpture]=4*(2x²+4xy)---> 8x²+16xy

we compare the value that JD says with the real value
(8x²+16xy) > (6x²+16xy)
the value that JD says is greater in comparison with the real value
This is because JD should also subtract the areas of eight hidden surfaces.

the answer is
JD should also subtract the areas of eight hidden surfaces

The length of a rectangle is 5 ft more than twice the width, and the area of the rectangle is 63ft. Find the dimensions of the r

Sati [7]

I don’t think that’s possible. Unless the answer they’re looking for is in the decimals, 63 is only divisible by 1, 3, 7, 9, 21, and 63. Seeing as the formula for the area of a rectangle is a= lw, having something like that problem wouldn’t be possible. I’m most likely wrong, but I’m not completely sure. Please feel free to correct me!!
