To find the mean (average), u add up all the numbers, then divide by how many numbers there are.
(200 + 150 + 325 + 100 + 75) / 5 = 850/5 = 170 <== the mean
Tell me the question and I’ll help you with it is it simplify or evalute etc.
Actually Welcome to the Concept of the Similarities.
Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,
hence for,
1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3
hence the value of x is 12 , ===> x = 12 .
2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,
hence we apply the relation,
x = 2*4.5 ===> x = 9 units.
The answer is 15 i believe
<em>The answer would be 1 1/5
</em>

</em>
<em>48/40 = 1 8/40
</em>
<em>
</em>
<em>1 8/40 Simplify to 1 1/5
</em>
