Answer:
The correct option is A.
Step-by-step explanation:
Dilation represents the enlargement and compression of a figure. Whether it is an enlargement or compression, It totally depends on the scale factor.
If the absolute value of scale factor is more than 1, then it represents the enlargement and if the absolute value of scale factor is lies between 0 to 1, then it represents the compression.
Image and preimage are similar figures. It means the corresponding angles are congruent or corresponding sides are proportional.
It is given that LMN is dilated by a scale factor of 0.5.
Since scale factor is lies between 0 to 1, therefore it shows the compression.
Therefore sides of L'M'N' is smaller than LMN.
Since corresponding angles of similar figure are congruent.
So, options B, C and D represent the correct statements. Only option A represents a false statement because the sides of similar figure are proportional not congruent.
Therefore option A is correct.
Answer:
The coefficient 3.99 represent the cost of one bottle of nail polish.
Step-by-step explanation:
Given:
The equation to represent the amount of money left after buying 'p' bottles of nail polish is given as:
The remaining amount with Itzel can be calculated as:
Remaining amount = Initial amount - Cost of 'p' bottles.
The above expression tells us two things:
1. Initial amount of money Itzel has was 25.
2. The cost of 'p' bottles of nail polish is .
Therefore, the cost of one bottle is calculated using the unitary method is given as:
Therefore, cost of 1 bottle of nail polish is 3.99. Hence, coefficient 3.99 represent the cost of one bottle of nail polish.
