without using a calculator decide which option is better value for money: 300g Jelly beans $5.80 or 500g Jelly beans $9.90
yarga [219]

Answer:

500g Jelly beans $9.90

Step-by-step explanation:

To know the values.

Let's know how much a gram will cost in each case

300g Jelly beans $5.80

1g = 5.8/300

1 g = 0.01933

500g Jelly beans $9.90

1g = 9.9/500

1g =0.0198

It's obvious that the second one has more value placed on it as it cost more per gram

Which figures demonstrate a translation?
Nuetrik [128]

Answer:

3rd and 4th Options are correct choices.

Step-by-step explanation:  

We have been given a graph and we are asked to find which of the given figures demonstrate translation.

Since we know that in translation every point of the object must be moved in the same direction and for the same distance. By translation we can shift a figure in upward, downwards, left and right directions.

Now let us see our given choices one by one.

1. Upon looking at figures represented by 1st option we can see that both figures are mirror images to each other. Since we can get mirror images reflecting the pre-image over an axis of symmetry. So the given figures are result of reflection, therefore, 1st option is not a correct choice.

2. We can see that the figures represented by 2nd option are similar. One figure is smaller and other is larger. Since we get a similar image by dilating our pre-image. Therefore, these figures are result of dilation and 2nd option is not correct indeed.

3. We can see that figures represented by 3rd option are same and these figures are result of shifting. We can see that 1st figure is shifted to right to get the second figure, therefore, 3rd option is a correct choice.

4. The figures represented by 4th option are same and these figures are result of shifting. We can see the figure in the bottom is result of shifting the upper figure downwards and then to right. Therefore, 4th option is a correct choice.

on a number line the coordinates of x, y, z, and w are -6, -3, 1 and 4 respectively find the lengths of the two segments below t
exis [7]

The lengths of the two segments below then tell whether they are congruent

YZ = 4

XW = 12

not congruent

This is further explained below.

<h3>What is a number line?</h3>

Generally, A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the

Number lines are used in introductory mathematics. It is generally accepted that a real number may be assigned to each point on a number line and that each point can be assigned to a real number.

YZ = Z - Y = 1 -(-3) = 4

XW = W -X = 5 -(-7) = 12

Because the segments are not the same length, they cannot be considered congruent.

In conclusion, It is self-evident that segment YZ will not have the same length as segment XW since it is just a portion of the latter.
