Jacob transformed quadrilateral FGHJ to F'G'H'J'.
Rudik [331]

Answer:

A. Reflection across the line x = 1

Step-by-step explanation:  

Please find the attachment.

We have been given that Jacob transformed quadrilateral FGHJ to F'G'H'J'.  We are asked to find which transformation Jacob used to reflect FGHJ to F'G'H'J'.

Since we know that while reflecting a figure, the line of reflection will lie between the original figure and reflected figure. Each point of the reflected figure will have the same distance from the line of reflection as the corresponding point of the original figure.              

Now let us see our given choices one by one.

A. Reflection across the line x = 1.

Upon looking at point G and G' we can see that both points are equidistant (2 units) from the line x=1. Other corresponding points of both quadrilaterals are also equidistant from line x=1, therefore, Jacob used the reflection across the line x=1 to transform quadrilateral FGHJ to F'G'H'J'.

B. Reflection across the line y = 1 .      

If Jacob had reflected quadrilateral across line y=1, the points of quadrilateral F'G'H'J' will lie in second and third quadrant. We can see from our graph that F'G'H'J' lies in 1st quadrant, therefore, option B is not a correct choice.

C. Reflection across the line y-axis.

If Jacob had reflected quadrilateral across y-axis, the coordinates of points of quadrilateral F'G'H'J' will be G'(1,4), H'(1,2), J'(4,0) and F'(2,5). Therefore, option B is not a correct choice.

D.  Reflection across the x -axis.

If Jacob had reflected quadrilateral across x-axis, the points of quadrilateral F'G'H'J' will lie in third quadrant. We can see from our graph that F'G'H'J' lies in 1st quadrant, therefore, option D is not a correct choice.

Please help?? its unit rate so plz help tell me how to do it
Lelechka [254]

Answer:

1.2 dollars

Step-by-step explanation:

You have to divide the dollar count by the pound count.

So basically:

6/5

This gives you 1.2 dollars.

When you do unit rate, you just have to divide one value by the other value.

The value you divide by, and the value you divde, vary depending on what the question asks.

For instance, if this question asked what the pound count for 1 dollar would be, you would end up divide the 5 pounds by 6 dollars(5/6) instead of divideing the 6  dollars by 5 pounds like we did above(6/5).

Hope this helps!

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?
Drupady [299]

Answer:

16.56\ g

Step-by-step explanation:

we know that

The density is equal to the mass divided by the volume

Let

x-----> the mass of marble

y----> the volume of marble

z----> the density of marble

z=\frac{x}{y}

in this problem we have

y=6\ cm^{3}

z=2.76\ g/cm^{3}

substitute and solve for x

2.76=\frac{x}{6}

x=2.76*6=16.56\ g

PLEASE HELP ITS MATH THANK YOUUUU
NISA [10]
Answer: 10 meters

Explanation:

29 cm : blank meters

So how do we get from 348 cm to 29 cm?

To figure this out we divide.

348 divided by 28 = 12

we divided by 12 so we do the same with 120

120 divided by 12 = 10

So that’s the answer.

I hope this makes sense and helps you :)

Jimmy's costume requires ⅞ + ½ + 1 3/4 yards of fabric. His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric tha
liq [111]

Answer:

The correct answer is fabric Jimmy's sister needs = \frac{73}{8} × fabric Jimmy needs = \frac{73}{8} × \frac{25}{8} yards of fabric.

Step-by-step explanation:

Jimmy's costume requires ⅞ + ½ + 1 \frac{3}{4} yards of fabric = \frac{7}{8} +\frac{4}{8} + \frac{14}{8} = \frac{25}{8} yards.

His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric that Jimmy needs = 3× (\frac{21}{24} + \frac{12}{24} + \frac{40}{24} ) yards of what Jimmy needs = \frac{73}{8} yards of what Jimmy needs.

The relationship between how much fabric Jimmy needs and how much fabric his sister needs is given by

Fabric Jimmy's sister needs = \frac{73}{8} × fabric Jimmy needs = \frac{73}{8} × \frac{25}{8} yards of fabric.
