What is the scale factor for pre-image IJKH to image MNOL?

Mathematics
1 answer:
solniwko [45]4 years ago
5 0

Answer:

Step-by-step explanation:

Given are two rectangles MNOL and IJKH

MNOL is the image and IJKH is the preimage.

OBviously similarity is preserved between these.

Hence sides will be proportional

i.e. l1/l2 = w1/w2 = Scale factor k

This can also be written as

Scale factor square = k^2=\sqrt{ \frac{areaI}{area2} }

Scale factor = square root of ratio of rectangle areas

Find ratio as

\frac{375}{135} =\frac{25}{9}

k = Scale factor = square root of the above fraction

=\frac{5}{3}

the ratio of men and women in a certain factory is 3 to 4. there are 198 men. How many workers are there?
LUCKY_DIMON [66]

3 men

4 women

7 total


3 men/ 7 total = 198 men/ x total

using cross products

3*x = 7 * 198

divide each side by 3

x = 7*198/3

x = 462

There are 462 workers


If you mean 3 men and 1 women for a total of 4 workers when you state a  ratio of men and women in a certain factory is 3 to 4.

3/4 =198/x

Using cross products

3x = 4* 198

Divide each side by 3

3x/3 = 4*198/3

x =264

264 workers


It all depends on how you define ratio of men and women in a certain factory is 3 to 4.   This is incorrect phrasing and I took it to be men to women.   You cannot have a ratio of men and women.

After a weekend at the beach, Lisa has $274 less than she had when she left. The equation that represents this situation is e=s−
Anon25 [30]
Well that's easy it basically tells you all you gotta do is plug in the numbers 

"E" is what you're trying to find out so you don't know that one it stays the same. 

"S" is the amount of money she started with and it says she started with $500 

And then she has $274 less than she started with. 

E = 500 - 274 

E= 226

She is left with $226 after her weekend at the beach. 

~Hope it helped~
