Rectangle a measures 12 cm by 3 cm. rectangle b is a scaled copy of rectangle a. select all of the measurements pairs that could be the dimensions of rectangle b.
a. 6 cm by 1.5 cm
b. 10 cm by 2 cm.
c. 13 cm by 4 cm.
d 18 cm by 4.5 cm
e. 80 cm by 20 cm.
can you me get the rights one for my hw

A,D,E

Step-by-step explanation:

scaled copy means the ratio of the two lengths would be same proportional constant.

The proportionality constant for Rectangle A is:

12/3 = 4

So any scaled version will have this proportionality constant same (4).

let's check:

A) 6/1.5 = 4 (OK)

B) 10/2 = 5 (NOT OK)

C) 13/4 = 3.25 (NOT OK)

D) 18/4.5 = 4 (OK)

E) 80/20 = 4 (OK)

So, correct options are A, D, and E

725 parts per hour.

step-by-step explanation:

hi there, this answer is actually really simple.

you can set it up as 1450/2 or 3625/5 to find the answer.

they want to know how much per hour is being made, so you just divide.

1450/2=725.

and that's how many are produced per hour.

hope this . : )
