Cynthia Besch wants to buy a rug for a room

Mathematics

6 0

The length and width of the rug is 20 and 11 feet respectively

The given parameters;

dimension of the room = 19 ft by 28 ft

maximum area of rug she can afford = 220 ft²

For a uniform stripe of floor around the rug, then suppose the uniform excess length of the floor to removed from each dimension = y

(28-2x)(19-2x)=220

532-94x+4x^2=220

4x^2-94x+312=0

x=39/2,4

For x=39/2, dimensions are negative.

The uniform dimension of the floor to be covered by the maximum area of rug she can afford = (28 - 4×2) and (19 -2×4 ) = 20 and 11

Thus, the dimensions of the rug should be 20 feet and 11 feet

Two gift shops sell postcards. Each gift shop charges a fixed amount per postcard. The prices, in cents, for different numbers o
Snowcat [4.5K]

1st gift shop:

120/4 = 30 cents each

180/6 = 30 cents each

390/13 = 30 cents each

 

2nd gift shop:

204/7 = 29.14 cents each

192/8 = 24 cents each

270 /9 = 30 cents each

360/10 = 36 cents each


 so if both gift shops have a fixed price then the 9 post cards would be the answer since it matches 30 each like the 1st gift store

\huge\boxed{\sf x = -2}

Step-by-step explanation:

\sf h(x) = 5x+2\\\\Put \ h(x) = -8\\\\-8 = 5x+2\\\\Subtract \ 2 \ to \ both \ sides\\\\-8-2 = 5x\\\\-10 = 5x\\\\Divide\ both \ sides \ by \ 5\\\\-10 / 5 = x \\\\x = -2 \\\\\rule[225]{225}{2}

Hope this helped!
