Answer:
1. The distances are accurate.
2. 57 miles
Step-by-step explanation:
<u>Quiz 1 solution</u>
1 mile = 1.60934 km
10 miles will be;
10 × 1.60934 = 16.0934 km
Distance on the sign is 16 km.
The distance is accurate since 16.0934 km rounded up to nearest kilometre is equal to 16 km.
13 miles will be;
13 × 1.60934 = 20.92142 km
The distance on the sign is 21 km
This distance is accurate since 20.92142 km rounded up to nearest kilometre equals 21 km
55 miles will be;
55 × 1.60934 = 88.5137 km
The distance on the sign is 89 km
The distance is accurate since 88.5137 km rounded up to nearest kilometre is 89 km.
<u>Quiz 2 solution</u>
1 km = 0.621371 miles
92 km will be;
92 × 0.621371 = 57.166132 miles
Rounding up the answer to nearest mile gives 57 miles.
First you get the length PX
secondly you use the sine rule a\sin A= b\sin B=c\sin C
hence hy = 30
you take 30\sin 90=18\X
cross multiply
sin 90 × 18 = 30×X
sin 90 = 1
1×18=30X
18\30=30X\30
0.6=X
then sin~1 0.6
answer 36.8699 as angle p
then get cos 36.8699
Answer:
The car has traveled 405 miles if it has 2.5 gallons of gas left in the tank.
