In 1923, a certain country underwent one of the worst periods in history of hyperinflation, which is extraordinarily large inf

alexgriva [62]

Answer: 3.498 * 10^26 % ; 16.9% per day

Step-by-step explanation:

Inflation rate = 11,000 per month

Hence, price after a month :

Final price = initial price (1 + rate)

Final price = 1 + 11000/100

Final price = (1 + 110) * initial price

Final price = 111 times the initial price

Hence inflation over the 12 month period :

(111)^12 = 3.498 * 10^24

(3.498 * 10^24) * 100% = 3.498 * 10^26 %

The daily inflation rate :

Number of days = 30

30th root of 3.498 * 10^24 = 1.169

(1.169 - 1) = 0.169

0.169 * 100% = 16.9% per day

EF is a median of trapezoid ABCD. The length of AB is 12, and the length of CD is 18. The length of BF is 4. What is the length

frez [133]

Answer:

Step-by-step explanation:

The diagram representing the trapezoid is shown in the attached photo. The median EF is a line segment that is half way between the 2 bases. The length of the median is the average of the two bases. Therefore,

EF = (12 + 18)/2 = 15

Two similar trapezoids are formed. They are ABFE and EFCD

By comparing both trapezoids, it means that

4/15 = FC/18

Cross multiplying, it becomes

4 × 18 = 15FC

72 = 15FC

FC = 72/15

FC = 4.8

Write the repeating decimal as a fraction 0.75<br>the 75 is repeating

kogti [31]

Let x = 0.757575... . Then

100x = 75.757575...

and so

100x - x = 75.757575... - 0.757575...

99x = 75

x = 75/99 = 25/33
