Sarah is making a scale drawing of a painting that is 48 in. wide by 120 in tall. her paper is 12 in. wide and 24 in. tall. She decides to use the scale 1 in. = 4in. is this a reasonable scale?
The scale is 1 in= 4 in.
1:4= .25 or 25%
So 12/48= .25 or 25%
24/120= .2 or 20%
The ratio does not match the height ratio.
What would we do without Ms. Sue??
Ms Sue: Answers question
Children: Dislikes
Ms Sue: "Why are you booing me? I'm right"
The answer is no. Every number here is dividable by 12.
12/12=1
24/12=2
48/12=4
120/12=10
Knowing this, you can divide for the simplest scale, and there's your answer, hope I helped
bro what is going on
im so lost😅

Geometry B Unit 3 Lesson 7: Similarity Unit Test/10 Questions Including 2 Essay Questions-------------------------------------------------------------------------------------------------------Overall Test Total Questions 13--------------------------------------
Let's Get Started!!!!
1. A) 1:725
2. B) JKML~PQRS; 8:4.8
3. A) ΔJMK~ΔMLK~Δ JLM
4. B) X = 9/4, Y = 15/4
5. A) X = 15.7
6. B) yes; by AA~
7. A) √21
8. D) 49
9. A) √70
10. B) 25
11. C) 13
Essay 12. Yes, it is. Sarah's scale is reasonable because the first step she did, is determining how big her paper is with the painting. Scale drawing is smaller than other diagrams depending on the terms of the dimensions with the original image, the building, and the object. The drawing of the scale is usually decreased at a very ongoing constant dimension. So, with Sarah's reasonable scale which is:
48/12 = 4
120/24 = 5
So, Sarah's scale from 1 to 4 is reasonable.
Essay 13. With the given statement in the image above. Statement 1: AB is x to BE and is = to CB x BD, and Reason 1: Given. We know these two, now the other statements and reasons.
Statement 2: CB/BE = AB/BD, Reason 2: Property of Cross Multiplication
Statement 3 ABC congruent to DBE, Reason 3: Vertical Angles
Statement 4: ABC ~ DBE, Reason 4: SAS Property of Similarity
These are the correct answers for the whole test. Trust them or don't, it's your grade and choice, just know that you'll maybe get a bad grade. No offense! Well, that's all from me today, bye and have a wonderful time.
