Choose ALL statements about percentages that are true. e
A)
15% of 30 is 12
B)
25% of 80 is 20.
30% of 50 is 25.
D)
30% of 60 is 18
E)
40% of 20 is 8

The correct answers are B, D and E

Explanation:

The best way to find if each of the statmenet is true or false is to find the percentage in each case. To do this, follow this general formula: Total number / 100 (100 representes the total) x specific percentage. Now, let's apply this formula in each statement

A)

30 ÷ 100 = 0.3 x 15 = 4.5  (This statement is false)

B)

80 ÷ 100 = 0.8 x 25 = 20 (This statement is true)

C)

50 ÷ 100 = 0.5 x 30 = 15 (This statment is false)

D)

60 ÷ 100 = 0.6 x 30 = 18 (This statement is true)

E)

20 ÷ 100 = 0.2 x 40 = 8 (This statement is true)

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
