Answer:

I'd guess 54

Step-by-step explanation:

If the sections are all equal sized, there's an equal chance the arrow/spinner would land on them. If you divide 240 by 5, you get 48. The closest number to 48 is 54.

Answer:

D = 2/5 or 0.4

Step-by-step explanation:

3/2 = 5d - 1/2

move the terms

3/2 - 5d = -1/2

calculate the difference

-5d = -2

divide both sides by -5

2 = 2/5

Answer:

40°

Step-by-step explanation:

Since triangle ABC is identical to triangle A'B'C', it has the same measures of respective sides and angles, and ang A is therefore equal to angle A'.

After rotational transformation, the measure of angle ∠A' = 40°.

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.

For the given situation,

The diagram shows the two triangles.

Triangle ABC is the original triangle and A'B'C' is the triangle obtained after the rotation of -120°.

From the definition, in rotational transformation the size and shape of the figure stays exactly the same. Then the angle measures are also remains the same.

Thus the measure of angle A' is [tex]\angle A' = \angle A = 40[/tex]

Hence we can conclude that after rotational transformation, the measure of angle ∠A' = 40°.

Answer:

The end point as when we multiply 4.3 x 4.7 we get 20.21 and if there is no end point in distance shown we can assume she displaced 20  meters in 4.7 and that 4.26 seconds had a larger end point.

However a starting and end point is always required.

Step-by-step explanation:

4.7 x 20

Change minutes into seconds (so that the final result would be in meters per second) we do not have to do this as all time is already in seconds.

=  4.7 seconds, Divide the distance by time: velocity = 20/4.7 = 4.25531915

= 4.3 m/s
