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
B=3

Answer:
20 1/4 ft
Step-by-step explanation:
Subtracting the four given lengths from 75 feet will tell you how much is left.
75 - (12 1/3 +16 1/6 +11 3/4 +14 1/2) = 75 -54 3/4 = 20 1/4
Gabriel has 20 1/4 ft of material left for his 5th banner.
Answer: $160
Step-by-step explanation:
You'll need to find the mark-up price first: $2400+1/3
1/3= $800
$2400+$800= $3200
$3200 is the mark-up price
Then you have to find the discount:
1/5 of $3200
$3200/5= $640
$3200-$640= $2560
Lastly, you have to find the profit:
$2560-$2400= 160
