Answer:
1. 247 mg ÷ 10 = 24.7 cg
2. 247 mg ÷ 100 = 2.47 dg
247 mg ÷ 1000 = 0.247 g
Step-by-step explanation:
1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.
2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.
3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.
Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 = ; y = 20 sin 45 ; y= 14.14 miles
cos 45 = ; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
= +
= +
= 3131.08
=
z = 55.96 miles
