Answer:
= 30 joules
Step-by-step explanation:
Work done is given by the product of Force and distance
Work done = Force × distance
Work is measured in joules.
Force = 20 N , distance = 1.5 m
Thus;
Work done = 20 N × 1.5 m
<u> = 30 Joules</u>
Answer:
D. -3 + 6
Step-by-step explanation:
Starting from zero, we move 3 units to the left. This gives -3.
We now change direction and move to the right 6 units. This gives +6.
Putting the two movements together gives
The correct choice is D.
Note that moving to the left is considered to be negative while moving to the right is considered positive.
The least amount of information needed to establish congruence is; Angles M and M' are congruent, and angles N and N' are congruent.
<h3>What is the least amount of information needed to determine if the two triangles are similar?</h3>
If follows from concept of congruence that two triangles are congruent only if all three angle measures are congruent or all corresponding sides are in the same ratio.
Hence, when angles M, N and M', N' are established as congruent, it follows that the measures are equal respectively.
Ultimately, the measure of angles L and L' are equal and hence, all three angles are congruent in each triangle.
Therefore, the least amount of information needed is; Angles M and M' are congruent, and angles N and N' are congruent.

Answer:
d = 28 cm
r = 14 cm
Step-by-step explanation:
Circumference = Pi × Diameter
( Divide both sides by Pi )
Circumference ÷ Pi = Diameter
28 ÷ π = Diameter
Diameter = 28
Radius = Half the diameter
28 ÷ 2 = 14
