First, put them in order from least to greatest. 63, 75, 89, 91. To find the middle number, add 75 and 89 together, 164, and divide by 2. The answer is 82.
To find 85% of 36 we have to transform 85% into fraction and then multiply it by 36.
85% is


- its the result
2,875; 2500 x .15 (15%) = 375; 2,500 + 375 = 2,875 Total
A=l*w
66= (1ft+L)*(2W)
you can find the answer from this
hope i helped:)
Yes, the new coordinates would be:
R': (9,9)
P': (3,3)
Q': (9,3)
You would multiply all of the current coordinates by three (its scale factor of enlargement) to obtain these answers. Hope this helps!
