For the second one the answer should be 3
Answer:
I'm pretty sure it's 500
Step-by-step explanation:
(2(-5)^4)^2 / -5^0 x -5^5
(2 x 625)^2 / -5^0 x -5^5
(1250)^2 / -5^0 x -5^5
1,562,500 / -5^0 x -5^5
1,562,500 / -1 x (-3,125)
1,562,500 / 3,125
500
70% of 300 is 210, and 1/4 of 800 is 200, so 70% of 300 is greater. Hope this helps!
43 percent
1$ is equal to 100 cents, so 43 cents out of 100 cents, or 43/100 equals 43 percent
Answer is choice C
"Dilate with a scale factor of two" means "multiply each coordinate by two"
A = (2,3) turns into A' = (4,6)
B = (3,5) turns into B' = (6,10)
C = (7,4) turns into C' = (14,8)
Side Note: this quick shortcut only works if the center of dilation is the origin (0,0). If the center of dilation isn't the origin, then you will have to do a translation (shifting) before you can use the trick, and then you'll have to shift back. The idea of the shifting is so that the center of dilation becomes the origin on a temporary basis. Because no mention is made of the reference center, it is assumed to be the origin by default.
