Let the income of first person be 9x
let the income of the second person be 7x
difference b/w their weekly income=9x-7x=200
=2x=200
x=100
therefore income of first person is 9x=9×100=RS 900
therefore income of second person is 7x=7×100=RS 700
Answer:
distance of his partner from the base of the tower ≈ 53.6 ft(nearest tenth)
Step-by-step explanation:
The forest ranger is on top of a fire tower and he sees his partner on the ground at the angle of depression of 40°. The tower is 45 ft tall.
The illustration forms a right angle triangle.
The adjacent side of the triangle is the distance from the partner to the base of the tower.
Using tangential ratio
tan 40° = opposite/adjacent
tan 40° = 45/adjacent
cross multiply
adjacent tan 40° = 45
divide both sides by tan 40°
adjacent =45/tan 40°
adjacent = 45/0.83909963117
adjacent = 53.6289116667
distance of his partner from the base of the tower ≈ 53.6 ft

It will be hard for me to demonstrate the equation
Answer:
second answer is the correct one
Step-by-step explanation:
When we have two fractions, it's best to find the least common denominator.
This means that we need two fraction that are EQUAL to the other two, but have different denominators (must be the smallest but common).
Alright, let's multiply
9/10 * 3/3 = 27/30
5/6 * 5/5 = 25/30
Now we have our two fractions:
27/30 and 25/30
