Answer:
108units^2
Step-by-step explanation:
1) area of a trapezoid formula:
((a+b)/2)h
where a=base 1
b= base 2
h=height(24)
so
(8+1)/2=4.5
4.5*24=108
area is 108 units^2
I'd say there are two significant figures in the number 520, and those are 5 and 2, because trailing zero in a number without decimals is rarely considered to be significant.
Now, the difference between a systematic error and a random error is that a systematic error occurs over and over again, whereas a random error is random and may never be repeated.
32 rides in total.
He goes on 3/8 of all the rides.
x 3
--- = ---
32 8
8x = 32 * 3
8x = 96
/8 /8
x = 12
Norman goes on 12 of the rides.
