Let’s start with Y
Y= -2x+4. Which is positive 2x
Now 3(2x)=x-2
We still don’t know the numeral of X
3(2x)=6x
6x= x-2
Therefore your answer would be 6x=x-2
First we have to find the missing angle. And we know that sum of the measurement of angles of a triangle is 180.
So we will get
Now we use sine law, which is
Substituting the values, we will get
The formula of area of triangle, for the given triangle is
The last two answers would be correct. This is because pi is an irrational number, 22/7 is a rational number, and 3.14 is a rational number.
Hello!
Let's put this into a system of equations and have a represent the apples and o represent the oranges.
o=2a+2
0.5o-0.5a=4
Since we can already so what o equals (2a+2) we will substitute it into the second equation and solve for a.
0.5(2a+2)-0.5a=4
1a+1-0.5a=4
1.5a+1=4
1.5a=3
a=2
Now that we know the value of a will put a into the first equation to find o.
o=2(2)+2
o=4+2
o=6
There were 6 oranges and 2 apples.
I hope this helps!
The radius of cone is 2 inches
<em><u>Solution:</u></em>
<em><u>The volume of cone is given by formula:</u></em>
Where,
"V" is the volume of cone
"r" and "h" are the radius and height of cone respectively
Given that, volume of a cone is 16 pi cubic inches
Its height is 12 inches
Therefore, we get,
V = cubic inches
h = 12 inches
r = ?
<em><u>Substituting the values in formula, we get</u></em>
Since, radius cannot be negative, ignore r = -2
Thus radius of cone is 2 inches
