Answer:
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE
Step-by-step explanation:
A) six times one tenth plus three times one hundredth plus two times one thousandth < six hundred twenty-nine thousandths
8,403.00
<629000 FALSE
B) six times one tenth plus three times one hundredth plus two times one thousandth = six hundred twenty-nine thousandths
8403= 629000 FALSE
C) six hundred twenty-nine thousandths < six times one tenth plus three times one hundredth plus two times one thousandth
629000<8403 FALSE
D) six hundred twenty-nine thousandths > six times one tenth plus three times one hundredth plus two times one thousandth
629000>8403 TRUE

Answer: 8.525
Step-by-step explanation:
let
x = the number of party favors in each of the 27 boxes
y = the number of party favors in the last box
the total number of party favors is 1,552
27x + y = 1,552
since 1552 = 57*27 + 13
if we assume that y<x we conclude that there are 57 party favors in each of the 27 boxes and 13 party favors in the last box.

A) The first step needs 100 bricks, the second needs 98, the third needs 96, and so on. Therefore the number of bricks for the nth step is: a_n = a_1 + d(n-1), where a_1 = 100 (the first term), d = -2 (difference).
a_n = 100 - 2(n-1) = 102 - 2n, and for the 30th step, a_30 = 102 - 2*30 = 42. So the top step will need 42 bricks.
b) The total staircase will need: 100 + 98 + 96 + ... + 44 + 42, and there are n = 30 terms. Using the formula for the sum of an arithmetic sequence:
S = (a_1 + a_n)*n/2 = (100 + 42)*30/2 = 2130
Therefore, 2130 bricks are required to build the entire staircase.
