Answer:
The correct option is C
Step-by-step explanation:
The organizers of a fair projected a 25 percent increase in attendance this year over that of last year
Let x = the attendance for last year
The projected attendance for this year would be last year's attendance + 25% of last year's attendance. This means
Projected attendance for this year
= x + 25/100 × x
= x + 0.25x = 1.25x
But attendance for this year actually decreased by 20 percent.
This means the actual attendance for this year would be
attendance for last year - 20% of attendance for last year. This means
Actual attendance for this year is
x - 20/100 × x
= x - 0.2x = 0.8x
percentage of the projected attendance that was the actual attendance would be
0.8x / 1.25x × 100 = 0.64 × 100
= 64%
The correct option is C

Answer:
140 swings
Step-by-step explanation:
as we know that it completes 7 swings in 3 seconds so, to find swings of 1 second =7/3
an now we have to find swings of 60 seconds(1 minute=60 seconds)
so, swings of 1 min = 7/3×60
= 140 swings
2+4+6+8 = "i=1" "n=4" Σ 2i
