Buffy just put some money into a CD that pays 10.1% interest, compounded monthly. According to the rule of 72, in approximately

quester [9]

Let the principal be 'x' then the Amount will be 4x.

As the interest is compounded monthly:

Rate of interest = 10.1 % = 10.1/(100*12) = 0.101/12

Time = 12t

Amount = Principal[1 + Rate/100]

⇒ 4x = x[1 + 0.101/12]¹²t

⇒ 4x/x [1 + 0.008416667]¹²t

⇒ 4 = [1.008416667]¹²t

⇒ log(4) = log[1.008416667]¹²t

⇒ 0.602059991327 = [0.003640014891]¹²t

⇒ 12t = 0.602059991327/0.003640014891

⇒ 12t = 165.400419876

⇒ t = 165.400419876/12

t = 13.78 years or 13 years 9 months.

So, it is about 13 years 9 months she will have 4 times the amount of money.

Which angles below are complementary?

tigry1 [53]

9514 1404 393

Answer:

∠KXN and ∠QXT

Step-by-step explanation:

The measure of each angle is the difference of the scale values that the rays intercept. (The same scale needs to be used for each ray.) Of course, complementary angles have a sum of 90°.

Here, we'll refer to angle aXb as "ab".

NP = 95 -35 = 60

PQ = 35 -20 = 15 . . . not complementary to NP

KN = 165 -95 = 70

QT = 20 -0 = 20 . . . complementary to KN ⇒ your answer

JK = 180 -165 = 15

PQ = 35 -20 = 15 . . . not complementary to JK

JK = 15

NK = KN = 70 . . . not complementary to JK
