B.
Answer:
The perimeter of the p triangle = 38.4 cm
Step-by-step explanation:
Given
The perimeter of a triangle z be = 48 cm
The triangle is dilated by a scale factor of 0.8
To determine
What is the perimeter of the triangle after it is dilated by a scale factor of 0.8?
- As the scale factor < 1, it means the new perimeter will be reduced.
The new perimeter of the triangle p can be calculated by multiplying the perimeter of the original triangle z by 0.8
i.e.
Perimeter of triangle p = 48 × 0.8 = 38.4 cm
Therefore, the perimeter of the triangle p is = 38.4 cm
31 cups because 38 cups fit into 9 1/2 quarts so subtract 7 from 38 you get 31
C represents the cost. R represents the number of rooms.
C=50 + 12R
