Answer:
Step-by-step explanation:
<span><span>In most statistical models
to represent easy percentages, circle is mostly preferred. It is purposefully
designed or rather allotted for functions that included 100%. A pie chart in
technical terms. Imagine an uneaten cake would
represent a 100%. </span></span>In most case scenarios,
when you eat one slice of the cake. You take a portion that decreases it 100%
or a whole presentation, for instance you took 25% slice of cake, what’s left
will be 75% and then when you put back again, the 25% slice will present the
whole 100%. In words, 25% slice of a cake you take, what’s left will just a
portion 75% and unless you put it back it will be whole again.
|PR| = |PQ| + |QR|; |PQ| = |QR| conclusion |PR| = 2|PQ|
|PQ| = 3y; |PR| = 42; |QR|=?
subtitute
42 = 2(3y)
6y = 42 |divide both sides by 6
y = 7
|QR| = 3(7) = 21
.015 + .06= .075
not sure if this is correct i did my best
9 dived by 3 = 3
so he surfed for 3 hours = 1/3 of 9
and there are 6 hours left
so he spent 6 hours building a sandcastle
