1 dm represents 100 m implies that 10 cm represents 100 m, so the scale is 1 : 10, that means that 1 cm is 10 m in the map.
Answer:
x1 = -5 x2 = 8
y1 = 6 y2 = -4
Distance = Square Root ((x2 - x1) ^2 + (y2 - y1)^2)=
Sqr root [(8 --5) ^ 2 + (-4 -6) ^ 2] =
Sqr root [13^2 + (-10)^2] =
Sqr root [169 + 100]
= Sqr root [269] = 16.4012194669

Answer:GCF of 45 and 63 is 9.
Step-by-step explanation:
factors of 45 are 1,3,5,9,15,45
factors of 63 are 1,3,7,9,21,63
so the greatest common factor or GCF of 45 and 63 is 9
