We know that
the dimensions of the original rectangle are
18.6 mm x 31 mm

the dimensions of the reduced rectangle are
3 mm x ? mm

step 1
find the scale factor
scale factor=3/18.6------> 1/6.2
then
the other dimension of the reduced rectangle is
31*(1/6.2)-----> 5 mm

perimeter of the reduced rectangle=2*[3+5]-----> 16 mm

the answer is
The perimeter of the reduced rectangle is 16 mm

storchak [24]

Answer:

$99/$115 x 100% = 86.086% of the original price

So 100% - 86.086

= 13.9 = 14%

Or you could just do (115 - 99) x 100 which gets the same answer.

Luis wants to buy a skateboard that costs $89.99. He has $30 saved. He wants to save $11 each week until he has enough money to

Diano4ka-milaya [45]

<h3>Answer: 6 weeks.</h3><h2>Your explanation</h2>

You want to take 11 and multiply 11 by 6 and get 66. Then add 66 and 30 and get 96. That's more then enough for the skateboard. 5 weeks will only equal 85, so 6 weeks is the least you can do.
