Anna walks 1 mile in 18 minutes. 18 x 2.5 = 45. if she walks 3 miles instead of 2.5, your only adding half of 18. so 45 + 9. Anna will walk 3 miles in 54 minutes. Hope that helped!
All you got to do first is:
Change the 9% to decimal, which is .9
and then multiply all numbers
$2860 x .9 x3 is $7,722
Hope this helps! (Hope im right)
Scale Factor (K) = (new length/measure)/ (original length/measure)
for x-coordinate = 8/2 = 4
for y-coordinate = 16/4 = 4
K=4, expansion
K is the representation of "scale factor". Scale factor is the ratio of the lengths involved of the similar figures. It can be used to identify the kind of dilation, whether it is contraction or expansion. If the Scale Factor is greater than 1, then that means expansion and if it is less than 1, then it signifies contraction.
