Answer:
n=30
Step-by-step explanation:
1/4(n+2)=8
1/4n+2/4=8
1/4n+2/4-2/4=8-2/4=7 2/4
1/4n=7 2/4
1/4n (4)=7 2/4 x (4)
n=29+2=30
Answer:
Area of Triangle QRP = 3
Step-by-step explanation:
According to Question , We have a circle With Centre 'O' & Area 48 .
Area Of Circle = 48
= 48
r =
Now We Have Two Points Given On Circle Q & R , P Is Circumcentre Of Triangle QRO .
Thus A Circle Can Also Be Formed with Centre P . ( See attachment For Diagram )
Now The Diameter of Circle With Centre P = Radius Of Circle with Centre O
so Radius Of Circle With Centre P() =
Now We Have To Find Area Of Equilateral Triangle .
A =
A=
The Area Of PQR is = 3
For Diagram , Please Find In Attachment
The idea is that one variable is the effect of another variable or, to say it another way, that one variable precedes and/or causes another. The dependent variable is the variable to be explained (the 'effect”). The independent variable is the variable expected to account for (the “cause” of) the dependent variable.
160 out of 400 equals : 160/400
If you shorten this, then you will get 2/5, which is the same as 40/100
Which will give you 40%
I hope this help you out
