A programmer wants to display how the shape of a rectangle with a fixed perimeter of 300 inches can be changed by varying the re

stiv31 [10]

If the rectangle has a fixed width of 300, it means that

$2(l+w)=300 \iff l+w=150 \iff w=150-l$

where $w$ and $l$ are width and length, respetively.

So given the length $l$ , the are would be

$l\times w = l\times (150-l)=-l^2+150l$

780 at 5.25 for 10 months what is the amount of simple interest

Annette [7]

Answer:

$814.13

Step-by-step explanation:

Recall that the simple interest formula is a=p(1+rt).

a= final amount (Unknown)

p=starting amount ($780)

r= interest rate (5.25= 0.0525%)

t=time in years (10 months =5/6 years)

Plug numbers into formula:

a=780(1+5.25*5/6)

Solve parenthesis first according to PEMDAS:

a=780(1.04375)

Multiply:

814.125

Round to nearest hundredth (cent):

$814.13
