I'm pretty sure it's 1/10 because it is one out of ten instead of one out of 12 ya feel
Answer:
The answer is below
Step-by-step explanation:
a) Triangle A is attached in the image below.
The base of triangle A is 3 units and its height is 3 units. The area of a triangle is given as:
Area = (1/2) × base × height
Area of triangle A = (1/2) × base × height = (1/2) × 3 × 3 = 4.5 unit²
Area of the scaled copy = 72 unit²
Ratio of area = Area of the scaled copy / Area of triangle A = 72 unit² / 4.5 unit² = 16
Hence the scaled copy area is 16 times larger than that of triangle A.
b) For the scaled copy:
Area of the scaled copy = (1/2) × base × height = 72 unit²
base × height = 144
Since the base and height are equal
base² = 144
base = 12, also height = 12
Base of scaled copy = 12 = 4 × base of triangle A
Therefore the scale factor used is 4
Answer:
C.) 33.60
Step-by-step explanation:
OMP. = $56
D. = 25%
0.25 * $56 = $14
SP. = $56-$14=$42
CD. = 20% of Selling price
= 0.20 * $42 = $8.40
FSP. = $42-$8.40 = $33.60
