@princeevee do you have any idea about this ?

2 months ago
princeevee:

i'm thinking it's C.

2 months ago
princeevee:

that's what i think is the closest to 3/2

2 months ago
jhonyy9:

so my idea that than the top has a width of 3 and length of 8 and similarity ratio of 3/2 so the bottom has width 3*3/2 = ? and length of 8*3/2 = ?

@Vocaloid

princeevee:

24/3 is still 8

2 months ago
jhonyy9:

exactly

2 months ago
princeevee:

but 16 is a multiple of 8

2 months ago
jhonyy9:

how you get this 24/3 ?

2 months ago
Vocaloid:

8*3/2 is 24/2 not 24/3

2 months ago
jhonyy9:

8*3/2 = ?

2 months ago
jhonyy9:

@princeevee do you understand it ? multiply 8*3 and divide by 2

2 months ago
jhonyy9:

and the width the same 3*3/2 = ?

2 months ago
jhonyy9:

@princeevee so in this way what choice is right ?

2 months ago
princeevee:

12

2 months ago
princeevee:

A?

2 months ago
jhonyy9:

yes the bottom length

2 months ago
jhonyy9:

yes exactly A .

jhonyy9:

do you understand it now ?

Vocaloid:

if you look at the diagram MP and SV are corresponding right? so it either has to be MP/SV or SV/MP depending on which one gives you an answer choice

princeevee:

1.3 seems close, i guess

2 months ago
Vocaloid:

good, 1.3

Vocaloid:

the smaller width is 2 it says the scale factor is 3/4 so 2 = 3/4 * large width, solve for large width

2 months ago
princeevee:

so, lets see...

2 months ago
Vocaloid:

large width is being multiplied by 3/4 right? so you just need to divide both sides by 3/4 to isolate what large width is

2 months ago
princeevee:

so 5/3/4?

2 months ago
Vocaloid:

if you want to do the length instead that's fine 5/(3/4) = ?

2 months ago
Vocaloid:

remember your rules for dividing fractions, flip the fraction over and change the sign to a multiplication sign 5/(3/4) = 5 * (4/3) = ?

2 months ago
Vocaloid:

rules for multiplying fraction: multiply the numerators first 5 * 4 then divide by the denominator 3 20/3 or in other words, 6 2/3

2 months ago
Vocaloid:

making the first option the only viable choice

Vocaloid:

we don't know anything about the side lengths of MP , MN, JK, or JL, just the angle between them therefore there's no proof that these two shapes are similar

Vocaloid:

triangle proportionality theorem DB/BC = DE/EF fill in the missing side lengths and see which proportion matches

2 months ago
Vocaloid:

any progress yet? you just need to look at the diagram to see what the side lengths are, plug them into the ratio, and see which answer choice matches the ratio

B? sorry, i'm kinda multitasking chores at the moment, continue please
