We know that
in the first triangle
the ratio of the legs are
4.5/1.5-----> 3

then
case <span>A) 6 m and 2 m ------> ratio=6/3----> 3
so
</span><span>the legs of a second triangle are proportional to the lengths of the legs of the first triangle

</span>case B) 8 m and 5 m ------> ratio=8/5---->1.6
so
the legs of a second triangle are not proportional to the lengths of the legs of the first triangle

case C) 7 m and 3.5 mm ------> ratio=7/3.5---->2
so
the legs of a second triangle are not proportional to the lengths of the legs of the first triangle

case D) 10 m and 2.5 m ------> ratio=10/2.5---->4
so
the legs of a second triangle are not proportional to the lengths of the legs of the first triangle

case E) 11.25 m and 3.75 m ------> ratio=11.25/3.75---->3
so
the legs of a second triangle are proportional to the lengths of the legs of the first triangle

the answer is
A) 6 m and 2 m
E) 11.25 m and 3.75 m

Select the choice that translates the following verbal phrase correctly to algebra:

maria [59]

w + 15 since increased by 15 means add on

12y + 11 since product of 12 and y means multiply 12 and y = 12y

one half n - 16 since one half of n and decreased by 1 6 , subtract 16

2b - 6 since Corinne is 6 years younger represented by b - 6

sum of their ages = b + b - 6 = 2b - 6

9h + 40

$ 9 per hour for h hours = 9 × h = 9h plus the $ 40 from carpool
