Answer:
50
Step-by-step explanation:
50$ because 20$ is 40%, so times that by 2 which you get 20$ and 80%. Then you divide 20 by 2 then you get 10 which is 20% so you add 10 and you get 50$ which is 100%
Answer: 8.55x10^13
Step-by-step explanation: 1.9 x 4.5 = 8.55 10^10 + 10^3 = 10^13
Answer: (4,8) which is choice A
f = 2/3 is the scale factor
x = 6 and y = 12 pair up to get the coordinates for point K's location
multiply f by x and y to get the new location
f*x = (2/3)*6 = (2/3)*(6/1) = (2*6)/(3*1) = 12/3 = 4
f*y = (2/3)*12 = (2/3)*(12/1) = (2*12)/(3*1) = 24/3 = 8
The results we get are 4 and 8. So (6,12) moves to (4,8)
This scale factor 2/3 = 0.667 is less than 1, so the image is smaller compared to the pre-image.
Answer:
The first choice.
Step-by-step explanation:
The area is multiplied by (1/2)^2 = 1/4.
This is because lengths are one dimensional and areas are 2 dimensional.
