Step-by-step explanation:
the perimeter is
2×length + 2×width = 1030 ft
length + width = 515 ft
length = width + 181
now we use that in the first equation :
(width + 181) + width = 515
2×width + 181 = 515
2×width = 334
width = 167 ft
because of
length = width + 181
length = 167 + 181 = 348 ft
Answer:
Step-by-step explanation:
The 20% discount amounted to ...
0.20 × $42.00 = $8.40
so the price before tax was ...
$42.00 -8.40 = $33.60
The tax amount is 3% of this value, so is ...
0.03 × $33.60 = $1.008 ≈ $1.01
So the total price paid for the shirt was ...
$33.60 +1.01 = $34.61
Randy paid $34.61 for the shirt after discount and tax.
___
<em>Alternate solution</em>
You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...
$42.00×0.80×1.03 = $34.608 ≈ $34.61
Answer:
30 + 12y
Step-by-step explanation:
Width of the rectangle is given by (5+2y)
Length of the rectangle is twice its width.
= 2*(5+2y)
=10 + 4y
Perimeter of the rectangle is the sum of all four sides of the rectangle.
Hence perimeter is given by 2 * (length + width)
= ![\[2* [(5 + 2y) + (10 + 4y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%285%20%2B%202y%29%20%2B%20%2810%20%2B%204y%29%5D%5C%5D)
Simplifying,
= ![\[2* [(15+6y)]\]](https://tex.z-dn.net/?f=%5C%5B2%2A%20%5B%2815%2B6y%29%5D%5C%5D)
= ![\[(30+12y)\]](https://tex.z-dn.net/?f=%5C%5B%2830%2B12y%29%5C%5D)
Hence the perimeter of the rectangle is given by (30 + 12y)
