Answer: <em>The correct options are.....</em>
<em>A)
and</em>
<em>B)
</em>
Step-by-step explanation:
Suppose, the number of e-mails Danette had in her inbox before she started reading was
.
Percentage of read emails is 80%, so the number of read emails ![= (\frac{80}{100}*X)=0.8X](https://tex.z-dn.net/?f=%3D%20%28%5Cfrac%7B80%7D%7B100%7D%2AX%29%3D0.8X)
<u>Thus, the number of unread emails</u>
, <u>which is given as</u>
.
So, the equation will be........
![X(1-0.8)=M\\ \\ \Rightarrow X=\frac{M}{1-0.8} (Answer: 1) \\ \\ \Rightarrow X=\frac{M}{0.2}\\ \\ \Rightarrow X=(\frac{1}{0.2})M=5M (Answer: 2)](https://tex.z-dn.net/?f=X%281-0.8%29%3DM%5C%5C%20%5C%5C%20%5CRightarrow%20X%3D%5Cfrac%7BM%7D%7B1-0.8%7D%20%28Answer%3A%201%29%20%5C%5C%20%5C%5C%20%5CRightarrow%20X%3D%5Cfrac%7BM%7D%7B0.2%7D%5C%5C%20%5C%5C%20%5CRightarrow%20X%3D%28%5Cfrac%7B1%7D%7B0.2%7D%29M%3D5M%20%28Answer%3A%202%29)
Thus, the expressions which could represent the number of e-mails Danette had in her inbox before she started reading are:
or ![5M](https://tex.z-dn.net/?f=5M)
The answer will be -3p -4
Answer:
Midpoint of AB = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)
x coordinate of point c = a
N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)
M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)
MA = √(3a / 2 - 0)² + b / 2 - 0)²
= √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4
NB = √(a / 2 - 2a)² + (b / 2 - 0 )²
= √( a / 2 - 4a / 2)² + (b / 2 - 0)²
= √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4
