The coordinates of the point N after the transformation is (-7,-4)

Explanation:

Given that the coordinates of the point N is (7,4)

The point is rotated 180° counterclockwise about the origin.

We need to determine the coordinates of the point N after the rotation 180° counterclockwise about the origin.

<u>Coordinates of the image:</u>

The transformation rule to rotate the point 180° counterclockwise about the origin is given by

$(x, y) \rightarrow(-x,-y)$

Substituting the point (7,4), we get,

$(7,4)\implies(-7,-4)$

Thus, the coordinates of the point N after the transformation is (-7,-4)

Abdul is riding on a bike course that is 80 miles long. So far, he has ridden 64 miles of the course. What percentage of the cou

hodyreva [135]

Answer:

80%

Step-by-step explanation:

Abdul is riding on a bike course

The bike course is 80 miles long

So far he has rifden 64 miles of the course

Therefore the percentage of the course in which Abdul has ridden so far can be calculated as follows

= 64/80 × 100

= 0.8 × 100

= 80%

Hence Abdul has ridden 80% of the course

A map is drawn to a scale of 1 cm to 250 cm.

Darina [25.2K]

Answer:

0.0015 km².

Step-by-step explanation:

It is given that a map is drawn to a scale of 1 cm to 250 cm.

$1\ cm\times 1\ cm=250\ cm\times 250\ cm$

$1\ cm^2=62500\ cm^2$

It is given that an airport has an area of 240 cm² on the map. So, its actual area is

$Area=240\times 62500\ cm^2$

$Area=15000000\ cm^2$

$Area=\dfrac{15000000}{10000000000}\ km^2$

$Area=0.0015\ cm^2$ $[\because 1\ km^2=10000000000\ cm^2]$

Therefore, the area of airport is 0.0015 km².

Pentagon A'B'C'D' is the image of pentagon ABCDE under a dilation,

viva [34]

Answer:

scale factor = $\frac{1}{3}$

Step-by-step explanation:

Compare the ratio of corresponding sides, image to original.

AB = 6 units and A'B' = 2 units, thus

scale factor = $\frac{A'B'}{AB}$ = $\frac{2}{6}$ = $\frac{1}{3}$
