Question

A photo is 6 inches long. Kamala enlarged the photo so that it is twelve inches long. By keeping the same proportion of the photo, what would be the width of the photo if the enlarged photo is 8 inches wide?

Two images of rectangles. The first is six inches long and ? wide. The second is twelve inches long and eight inches wide

Does this relationship represent direct or inverse variation? (1 point)
Using the appropriate formula, find k. (1 point)
Show your work and calculate the width of the original photo. (2 points)

Answer 1

can you help me @dpasingh

Answer 2

Sure @312856MLP

Answer 3

well i still m=need help with the Question above

Answer 4

This a kind of direct variation

Answer 5

ok what about the second one

Answer 6

Let the widht of the first image be k inches
therefore:
length of first image length of second image
----------------- = ---------------------
Width of first image Width of second image

i.e. \[\huge \frac{6}{k}=\frac{12}{8} \]
\[\huge 6 \times 8 = 12 \times k \]
\[\huge k= \frac{48}{12}\]
K= 4
Hence the width of the first image is 4 inches.

Answer 7

what

@dpasingh

Answer 9

i'm here

Answer 10

i dont under stand what u mean

Answer 11

What you want to say?

Answer 12

well i have to do this so that my math teacher understands it and i know see would not understand that

Answer 13

How you want to solve it?

Answer 14

well it has to be like to the point a little kid would understand it

Answer 15

Well, this is the question of ratio and is related to direct variation:
So the ratios of length and width of both images must be proportion, hence
6 : k = 12: 8
i.e. \[\huge \frac{6}{k}= \frac{12}{8}\]
Now solve it for k

Answer 16

@312856MLP

Answer 17

it might be easier to understand if you compare the original length with the enlarged length
to get from 6 inches to 12 inches had to multiply by 2
the width has to change by the same factor direct variation
let k be the original width then 2k = 8 solve for k, original width = 4 inches

Answer 18

okay so what about the last one

Answer 19

let k be the factor = 2
let w be the width of the original = 4
