Answer:
7.55 miles
Step-by-step explanation:
Given that :
Distance of descent = 1.5 miles
New elevation point after descent = 6.05 miles
The initial elevation of the plane before descent will be :
New elevation point after descent + Distance of descent
(6.05 miles + 1.5 miles)
= 7.55 miles
If you get rid of the whole number in that fraction, you will have 3/2.
So the opposite of that would be 2/3.
I believe the answer is 2/3.
Solution
Step 1:
There are three types of systems of linear equations in two variables, and three types of solutions.
1. An independent system has exactly one solution pair. The point where the two lines intersect is the only solution.
2. An inconsistent system has no solution.
3. A dependent system has infinitely many solutions.
Step 2
Solve the systems of the equations using the substitution method
Final answer
The system is dependent so there are infinite solutions.
Equivalent
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.
18/21 is the same as 6/7 when it is reduced by 3
so yes, they are equivalent
