Jeannie discovered that the ratio of kilometers to miles is 1 to 0.6. when her family was driving in canada, she saw a sign that said it was 80 kilometers to moncton. how many miles do they have to drive to get to moncton?

40 miles
48 miles
64 miles
75 miles

Miles do they have to drive to get to Moncton is:

48 miles

Step-by-step explanation:

the ratio of kilometers to miles is 1 to 0.6

i.e. 1 Kilometers=0.6 miles

80 kilometers=0.6×80 miles

                      =48 miles

Hence, miles they have to drive to get to Moncton is:

48 miles

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
