Steven has a rectangular rug with a perimeter of 16 feet. The width of the rug is 5 feet. What is the length of the rug?
vfiekz [6]
A rectangle has 2 sets of 2 sides; each set has the same length or width (depending on where it is on the rectangle).

If you have 2 sides with length, which can be expressed as 2L, and 2 sides of width, which can be expressed as 2(5) because they gave you the width in the problem, and the perimeter is 16...

2L + 2(5)=16. All you have to do is solve for <em>L</em>, which means <em>length</em>. 
<em />
2*5 is 10.

2L + 10 =16.

Subtract 10 on both sides.

2L = 6.

Divide both sides by 2.

L=3.

The length is 3. Let's check to make sure we're right:

2(3) + 2(5) = 16.

2*5 is 10, and 2*3 is 6. 6 + 10 is 16. We did it! I hoped this helped!

If tanisha has $100 to invest at 8% annum compounded monthly, how long will it be before she has $150?
marissa [1.9K]

An exponential behavior can be observed.

Let x be the number of years she has to wait.

100((1+0.08/12)^12x) = 150

Now solve for x.

log base 1.08/12 of 1.5 = 61.02 approx

12x=61.02

x=5.09 years
