What is 20% of 40, work it out

Darina [25.2K]

Hey there

Answer:

20% of 40 is 8 .

Step-by-step explanation:

In this question we are given a number that is 40 . And we have asked to find 20% of it .

Solution : -

$\longmapsto \qquad \: \: 20\% \times 40$

We know that ,

Percent ( % ) represent 1/100

So ,

 $\longmapsto \qquad \: \: ( 20 \times \dfrac{1}{100}) \times 40$ 

or ,

 $\longmapsto \qquad \: \: \dfrac{20}{100} \times 40$ 

Now cancelling zero :

$\longmapsto \qquad \: \: \dfrac{2 \cancel{0}}{1 \cancel{0} \cancel{0}} \times 4 \cancel{0}$

We get ,

$\longmapsto \qquad \: \: 2 \times 4$

$\longmapsto \qquad \: \: \blue{\underline{\boxed{\frak{8}}}} \quad \bigstar$

Therefore , 20% of 40 is 8 .

PLAN is a rectangle Its diagonals meet at O. Find the value of x if OP=2x+5 and OL=3x+2.

mariarad [96]

All 4 diagonals that have O as the origin in the middle that are connected to a corner will be the same length. So, since OP is the same length as OL, you can make the equations equal each other and solve for x.

2x+5 = 3x+2

Move the 2 over to the left by subtracting it from both sides

2x + 3 = 3x

Move the 2x over to the right by subtracting it from both sides

3 = x

What step should you perform to bisect an angle drawn on tracing paper

max2010maxim [7]

Answer:

Step-by-step explanation:

• Suppose the angle is PQR where Q is the midpoint.

• Keep the compass at angle vertex Q and adjust some wide setting (the width is not important).

• Without changing the compass, draw an arc across each leg of the angle

• Now keep the compasses on the point drawn on each leg, and draw an arc in the interior of the angle.

• Using a ruler, draw a line through the vertex to the point where the arcs cross
