The total montly housing cost is 575.16 + 23.70 + 87.40 + 76.36 + 21.18 + 19.30 = $803.10

tekilochka [14]
Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable

If the volume of a cube-shaped box is 729 cubic inches, which equation would you use to determine how many 1-inch cubes could fi
tensa zangetsu [6.8K]

<u>Answer</u>

∛729


<u>Explanation</u>

The volume of an object is the amount of space that the object can occupy.

The general formula for getting the volume of a regular object is:

Volume  = Base area × Height

For a cube, all sides are equal.

∴ Volume of a cube = length × length × length

                                   = (length)³

This means given the volume of a cube we can get the length of one side as shown.

Volume = (length)³

length = ∛volume.

∴ Volume = 729 in³

Length = ∛729 inches. This will give you the number of cubes 1 inches can fit along one side.

                                             Question # 17

<u><em>Solution:</em></u>

<em>Graphing the vertices of a triangle and transforming  by first translating</em>

<em>(x, y) → (x -3, y - 3) and then reflecting in the line y = x.</em>

As A(-1, 1), B(0, 3) and C(3, 4)

After Translation: (x, y) → (x - 3, y - 3)

A(-1, 1) → A'(-4, -2)

B(0, 3) → B'(-3, 0)

C(3, 4) → C'(0, 1)

After Reflection: in the line y = x

The reflection of the point (x, y) across the  

line y = x is the point (y, x).

A'(-4, -2) → A''(-2, -4)

B'(-3, 0) → B''(0, -3)

C'(0, 1) → C''(1, 0)

Pleas check the top right side of the <em>attached </em><em>figure a</em><em>.</em>

<em>Is the image same if the order of the transformation is switched ? (Reflection, then glide). Changing the order of transformation.</em>

<em>A(-1, 1), B(0, 3) and C(3, 4) </em>

<em> </em><em>After Reflection: in the line y = x </em>

<em>The reflection of the point (x, y) across the  line y = x is the point (y, x). </em>

<em> A(-1, 1) </em>→<em> A'(1, -1) </em>

<em>B(0, 3) </em>→<em> B'(3, 0) </em>

<em>C(3, 4) </em>→<em> C'(4, 3) </em>

<em> </em>

<em>After Translation: (x, y) </em>→<em> (x - 3, y - 3) </em>

<em> A'(1, -1) </em>→<em> A''(-2, -4) </em>

<em>B'(3, 0) </em>→<em> B''(0, -3) </em>

<em>C'(4, 3) </em>→<em> C''(1, 0) </em>

<em>No, the image is </em><em>no longer the same </em><em>if </em><em>order of the transformation</em><em> is </em><em>switched</em><em> as shown at the </em><em>right bottom of figure a</em><em>.</em>

<em />

<em>Answering the YES and NO Questions:</em>

<h3><em>Is the composition a glide reflection?</em></h3>

No, the composition is not a glide reflection as glide reflection is commutative. If we reverse the direction of the composition, the outcome will be affected.

Check the figure at top right side of figure a, and compare it with the figure at the bottom right side of figure a. They are not the same.

<h3><em /></h3><h3><em>Is the image same if the order of the transformation is switched ? (Reflection, then glide)</em></h3>

<em>No, the image is no longer the same if order of the transformation is switched as shown at the right bottom figure of </em><em>figure a</em><em>.</em>

<em>The </em><em>top right side of</em><em> </em><em>figure a</em><em> was transformed after first translation of (x, y) </em>→<em> (x - 3, y - 3) and then doing reflection across the line y = x. While the </em><em>bottom right side of figure a</em><em> was made by first reflection across the line y= x and then translation of (x, y) </em>→<em> (x - 3, y - 3. So, after changing the order both figures do not remain the same. </em>

                                          Question # 18

<em>Solution:</em>

<em>Graphing the vertices of a triangle and transforming by first 90 rotating clockwise and then reflection in the y axis.</em>

<em>A(-1, 1), B(0, 3) and C(3, 4) </em>

<em>After transforming by first 90 rotating clockwise about the origin. The new position of point (x, y) will be (y, -x) </em>

<em> A(-1, 1) </em>→<em> A'(1, 1) </em>

<em>B(0, 3) </em>→<em> B'(3, 0) </em>

<em>C(3, 4) </em>→<em> C'(4, -3) </em>

<em> </em>

<em>After Reflection: in the line y axis </em>

<em>The reflection of the point (x, y) in the line  line y-axis is the point (-x, y). </em>

<em> A'(1, 1) </em>→<em> A''(-1, 1) </em>

<em>B'(3, 0) </em>→<em> B''(-3, 0) </em>

<em>C'(4, -3) </em>→<em> C''(-4, -3) </em>

<em>Please check the </em><em>top right side</em><em> of </em><em>figure b.</em>

<em>If the order of the transformation were performed in reverse order ? (Reflection, then rotation), would the final image by the same?</em>

A(-1, 1), B(0, 3) and C(3, 4)

After Reflection: in the line y-axis

The reflection of the point (x, y) in the line y-axis is the point (-x, y).

A(-1, 1) → A'(1, 1)

B(0, 3) → B'(0, 3)

C(3, 4) → C'(-3, 4)

After transforming by first 90 rotating clockwise about the origin. The new position of point (x, y) will be (y, -x)

A'(1, 1) → A''(1, -1)

B'(0, 3) → B''(3, 0)

C'(-3, 4) → C''(4, 3)

<em>No, the image is </em><em>no longer the same </em><em>if </em><em>order of the transformation</em><em> is </em><em>switched</em><em> as shown at the </em><em>right bottom of figure b</em><em>.</em>

<em />

<em>Answering the YES and NO Questions:</em>

<em>If the transformation were performed in reverse order (reflection. then rotation), would the final image be the same?</em>

No, if we reverse the direction of the composition, the final image would not be same.

Check the figure at <em>top right side</em> of <em>figure b</em>, and compare it with the at the<em> bottom right side </em><em>of</em><em> </em>figure b. They are not the same.

<em />

<em>Would the reflection of triangle ABC in the line y = x have produced the same final image?</em>

<em>Yes, the reflection of triangle ABC in the line y = x would have produced the same final image. Compare the figure of the </em><em>bottom left</em><em> with the </em><em>bottom right </em><em>of </em><em>figure b</em><em>.</em>

<em />

<em>As A(-1, 1), B(0, 3) and C(3, 4) </em>

<em> After Reflection: in the line y = x </em>

<em>The reflection of the point (x, y) across the </em>

<em>line y = x is the point (y, x). </em>

<em> A(-1, 1) → A''(1, -1) </em>

<em>B(0, 3) →  B''(3, 0) </em>

<em>C(3, 4) →  C''(4, 3)</em>

<em>Hence, the reflection of triangle ABC in the line y = x would have produced the same final image. Compare the figure of the </em><em>bottom left</em><em> with the </em><em>bottom right </em><em>of </em><em>figure b</em><em>.</em>
