Tamora has just graduated from college. When she entered college four years ago, she took out a $9,100 subsidized Stafford loan, which has a duration of ten years. The loan has an interest rate of 5.4%, compounded monthly. If Tamora makes monthly payments, how much interest will she have paid in total by the time the loan is paid off? Round all dollar values to the nearest cent.
a.
$2,697.20
b.
$1,574.00
c.
$5,534.00
d.
$3,888.08

(the answer is A $2,697.20, just took the test)

answer: 4

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
