The answer to your question is 20 in

Step-by-step explanation:

Data

ratio  1 : 30

real length = 55 ft

toy train length = ?

Process

1.- Use ratio and proportions to solve this problem.

                           1 : 30 :: x : 55

solve

                           x = (55 x 1) / 33

Simplification

                           x = 55/33

result

                           x = 1.67 ft

2.- Convert the length to in

                         1 ft ------------------ 12 in

                        1.67 ft --------------   x

                          x = (1.67 x 12) / 1

-Simplification

                          x = 20/1

-Result

                           x = 20 in

Answer: 6x + 8y =1,245

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each person:

Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).

2 x+ 5 y=650

Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).

4x+3y = 595

Vertical addition:

2 x+ 5 y=650

+

4x+3y = 595

_________

6x + 8y =1,245

ale4655 [162]

Answer:

I think it is B. 30 degrees

Step-by-step explanation:

Because if ZUY is 90 degrees and half of 90 degrees is 45 degrees but TUZ is a little bit less than the middle part of ZUY it has to be less than 45 degrees by a little bit and the only option would be 30 degrees. Hope this helped (:
