Answer:

The sides of the first quadrilateral are 60 in, 40 in, 30 in and 12,5 in

The sides of the second quadrilateral are 24 in, 16 in, 12 in and 5 in

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

Arrange the sides of each quadrilateral from largest to smallest

First quadrilateral Second quadrilateral

Longest side=60 in Longest side=c in

Second side=40 in Second side=16 in

Third side= a in Third side= 12 in

Fourth side=b in Fourth side=5 in

$\frac{60}{c}=\frac{40}{16}=\frac{a}{12}=\frac{b}{5}$

Find the value of c

$\frac{60}{c}=\frac{40}{16}$

$c=60(16)/40$

$c=24\ in$

Find the value of a

$\frac{40}{16}=\frac{a}{12}$

$a=40(12)/16$

$a=30\ in$

Find the value of b

$\frac{40}{16}=\frac{b}{5}$

$b=40(5)/16$

$b=12.5\ in$

Productive use of machinery on a farm made it possible to decrease the number of tractors by 12 how many tractors does the farm

irina1246 [14]

So first off, the answer to this is 24 now think of x as the real or original sum or amount, also y as the new sum or amount.
y * 1.5 is x, and y+12 is x. Now flip that to figure out what is y, also which is what we need, and you have x/1.5 = y as well as x-12 = y. Use the equal values method and make an equation x/1.5=x-12. solve this equation to get x, which is 36. to figure out the new amount, y, you need to minus 12, which can help you get the answer which is 24.
