Answer:
Assume that the number is 100. Then, 20% of 100 is 20×100100 = 20. Increasing 100 by 20% means increasing 100 by 20 and the resultant number is 120.
Answer:
Center is the mean, an average of data. Spread is for range and standard deviation.
Step-by-step explanation:
Three-hundred and nine million, ninety-nine thousand, nine-hundred and ninety
Let the price of adult ticket and children ticket be a and c respectively
8a+5c=177.50 -> 24a+15c=532.5
12a+6c=255.00 -> 24a+12c=510
24a+15c-24a-12c=532.5-510
3c=22.5
c=7.5
a=17.5
N = 10, so the first option is correct. the work to prove this is below:
6n - 1 = 5n + 9 (add 1)
6n = 5n + 10 (subtract 5n)
n = 10
**** Now find the measure of the sides by plugging in what n equals. ****
CD = 4n + 2
CD = 4(10) + 2
CD = 40 + 2
CD = 42
********** Since this is a parallelogram, CD and FE have to be equal, so since FE = CD, and CD = 42, FE also has to equal 42. This makes the fourth statement true. *********************************************************************
Now find the measure of the other two sides.
CF = 6n - 1
6(10) - 1
60 - 1
CF = 59
Since CF = 59, DE also has to eqaul 59. This means that the third statement is also true.
Your answers should be:
n = 10
CF = 59
FE = 42
