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:
- 7/24
Step-by-step explanation:
Step 1:
3/8 = r + 2/3
Step 2:
9/24 = r + 16/24
Step 3:
9/24 - 16/24 = r
Answer:
- 7/24 = r
Hope This Helps :)
Well, if both Alexis and Tara mine salt for 40 hours... they'd have mine 1,000 pounds of salt. Is this what you were looking for?
What are the steps? Is there a photo?
M - 12 = -3
You would be able to find what m is by finding a number that can subtract 12 and get -3.
Hope this helps and have a nice day!!!
