Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)
Answer:
84m2
Step-by-step explanation:
The complex conjugate of <span>7i</span><span> is </span><span>−7i </span>The complex conjugate of a number
z is a number with opposite imaginary part.
So if <span>z=a+bi</span> then conjugate is: <span><span>¯z</span>=a−bi</span> for any <span>a,b∈R</span>
We can note, that if we represent all complex numbers in coordinate system, then for any number: the number z and its conjugate <span>¯z</span> are symetrical according to "real part" axis.
10. angle APB = (1/2) arc AB
108 = (1/2) arc AB
multiply both sides by 2 to clear the fraction
216 = arc AB
11. Area of regular Octagon s = 5 in
A = (P * apothem)/2 => => If you divide the octagon into 8 triangles, the apothem is the perpendicular height of the triangle.
A = (5 * 8 * 6)/2
A = 120 in^2
Area of regular Hexagon s = 5 in
A = (5 * 6 * 4.3)/2
A = 129 in^2
