Tara owes $14,375 in credit card debt the interest accrues at a rate of 5.3%. she is also borrowing $570 each month for rent from her parents. she does not pay interest on the money she borrows from her parents.
a) let f(t) represent the amount of money tara owes in credit card debt, where t is the number of years after interest begins to accrue. let g(t) represent the amount of money tara owes to her parents where t represents the number of years passed. write a function (f + g)(t) to represent the total money that tara owes.
b) how much will tara have to repay if she continues this way without any repayment for 2 years?

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

2/3
