Open the compass it is more than half of the distance between a and b, and scribes arcs of the same radius centered at a and b. call the two points where these two arcs meet c and d. Draw the line between c and d. CD it is the perpendicular bisector of the line segment AB. call the point where CD intersects AB and E

First: place the compass on the end of a line segment. second: adjust the compass to just slightly longer than half the line segment length. third: draw arcs above and below the line fourth: keeping the same compass width draw arcs from the other end of the line. last place ruler where arcs cross and draw line segment

Which of these sugar syrup will be the sweetest ? The sugar syrup with,Required to answer. Single choice.Immersive Reader (1 Poi
aleksley [76]

Answer:  c. 150g of sugar dissolved in 300ml water

Step-by-step explanation:

The concentration of sugar syrup will decide which syrup is sweetest. Concentration is defined as the amount of solute dissolved per unit volume of solution.

a) 50g of sugar dissolved in 150ml water

Concentration=\frac{50g}{150ml}=0.33g/ml

b) 100g of sugar dissolved in 500ml water

Concentration=\frac{100g}{500ml}=0.2g/ml

c)  150g of sugar dissolved in 300ml water

Concentration=\frac{150g}{300ml}=0.5g/ml

d) 250g of sugar dissolved in 1000ml water

Concentration=\frac{250g}{1000ml}=0.25g/ml

Thus 150 g of sugar dissolved in 300ml water has highest concentration and is sweetest.

The area (A) of a circle with a radius of r is given by the formula and its diameter (d) is given by . Arrange the equations in
ella [17]

Answer:

see explanation

Step-by-step explanation:

A = πr² ← r is the radius and r = \frac{1}{2} d ← d is the diameter

Hence

π (\frac{1}{2} d)² = A, that is

\frac{d^2\pi }{4} = A ( multiply both sides by 4 )

d²π = 4A ( divide both sides by π )

d² = \frac{4A}{\pi } ( take the square root of both sides )

d = \sqrt{\frac{4A}{\pi } }
