Answer:

B. 0 m

Step-by-step explanation:

We are given the movement of an object and are required to find the total displacement.

Now, as we know that 'displacement' refers to the length of the shortest path between two points.

i.e. We are required to find the shortest path the object covers.

Now, we can see from the figure below that the given movement,

40 m north → 40 m west → 40 m south → 40 m east,

will bring the object back to the original position ' O '.

Hence, the total displacement will be 0 m.

Find the area, round to the nearest tenth if necessary.
Strike441 [17]

Answer:

108 ft squared.

Step-by-step explanation:

The figure is made up of a triangle and a square.

The area of a triangle is (1/2)*b*h. The height of the triangle is 6 ft and the base is 9 ft, since the triangle shares a side with the square. Since all sides of the square are equal we know that the line that is shared by the triangle and the square must also be 9ft.

Area of the triangle: (1/2)*9*h = 27 Square feet

To find the area of a square you multiply b*h or sides squared

Area of the square: 9*9 = 81 squared feet

<em>Finally, you have to add the two areas together to get the overall area.</em>

<em />

So, 27  Feet Squared + 81 Feet Squared = 108 Feet Squared

During a sale, 20-cent candy bars were sold at 3 for 50 cents. How much is saved on 9 bars?
Mazyrski [523]

Answer:

Step-by-step explanation:

$0.30

Step-by-step explanation:

1 bar of candy = $0.20

3 bars of candy = $0.50

To solve, multiply for both:

If you pay for each candy bar individually, they each cost $0.20. Multiply 9 with 0.20:

9 x 0.20 = $1.80

If you pay for the candy bars by 3's, they cost $0.50 each pack. Divide 9 with 3, then multiply by 0.50:

9/3 = 3

3 x 0.50 = $1.50

Subtract the total cost of the individual from the pack:

$1.80 - $1.50 = $0.30

. $0.30 is your answer.
