Answer:
Scale factor = 4
Step-by-step explanation:
Scale factor = 
Since, S is being dilated with a scale factor to form T,
So, the figure S is the preimage and figure T will be the image,
Length of one side of image T = 8
Length of one side of preimage = 2
Therefore, Scale factor = 
= 4
Scale factor by which figure S has been dilated to form figure T is 4.
Answer:
see explanation
Step-by-step explanation:
Given that t and w vary inversely then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 
when w = 4
k = tw = × 4 = 
t = 
← equation of variation
When w = 9, then
t = 
= 
Answer:
3/1
Step-by-step explanation:
You would count how far up it goes, with out it passing the dot (also know as the rise) which in this case is 3. Then you would count the number of space to go to the side (the run) so in this case it would be 1. Finally you would put rise over run and get 3/1.
4.99/17 = x/1
17x = 4.99
x=4.99/17
x =0.29
answer: unit rate is $0.29/lb
