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?

48 miles

Step-by-step explanation:

1 Kilometer = 0.6 miles

80 kilometers = X miles

1 kilometer/0.6 miles = 80 kilometers/X miles

then cross multiply the ratio

X (1) = 80 (0.6)

X=48 miles

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

probability for j is 1/4

while

a is 1/6
