Answer:
(1;3)
Step-by-step explanation:
midpoint=(x1+x2;y1+y2)÷2
=(-2+4;-3+9)÷2
=(2;6)÷2
=(1;3)
Make a proportion to find the percent:
25/64 = x/100
Multiply 25 and 100, then divide that answer by 64. Then add a percent symbol.
25*100 =2500
2500/64 = 39.0625
39.0625%
Hundredths is the second digit after the decimal point, so the 2
the number next to it (1) is less than 5, so the number is rounded down to 3.72
