Answer:

5 by 10

Step-by-step explanation:

We know that the equation of a perimeter of a recangle is 2(l)+2(w), l being length and w being width. We know that l=2w. So the perimeter of this room would be:

2(2w)+2(w)=30

4w+2w=30

6w=30

w=5

l=2w

l=10

the dimensions are 5 by ten

Malachi bought a new fishing rod. The regular price of the fishing rod was $125.99. He bought it on sale with a 15% discount. Sa
Volgvan

If the discount is 15 percent, he still pays (100-15) or 85%

125.99 * 85%

125.99 * .85 = 107.09  is the price he pays for the rod

107.09 * .03 =3.21 is the sales tax

107.09+3.21=110.30 is the price of the rod with the discount and the tax
