For this case we have the following expression:
The last option tells us the following:
<em>There are 45 students in a group. There are also 10 adults in the group. What is x, the total number of students and adults in the group?</em>
So, the variable x can not represent adults and students because they tell us that 45 are clearly students. The equation is not fulfilled with this last option.
Answer:
Option D
Answer:
i. Colonel is about 201 feet away from the fire.
ii. Sarge is about 125 feet away from the fire.
Step-by-step explanation:
Let the Colonel's location be represented by A, the Sarge's by B and that of campfire by C.
The total angle at the campfire from both the Colonel and Sarge = +
=
Thus,
<CAB = -
=
<CBA = -

i. Colonel's distance from the campfire (b), can be determined by applying the sine rule;
=
=
=
cross multiply,
b =
= 200.8993
Colonel is about 201 feet away from the fire.
ii. Sarge's distance from the campfire (a), can be determined by applying the sine rule;
=
=
=
cross multiply,
a =
= 124.8073
Sarge is about 125 feet away from the fire.
