Scientific notatnio, the first number has to be less than 10
14.35 times 0.1=1.435
we have to make it be able to jump back
1.435 times 10¹ is scientific notaiton
Answer:
x=6 and y=2
Step-by-step explanation:
3x-2y=14 _1st equation
5x+y=32 _2nd equation
Multiplying 2nd equation by two and adding both equation
3x-2y=14
10x+2y=64
_________
13x=78
x=78÷13
x=6
Putting the value of x in 1st equation
3×6-2y=14
18-2y=14
2y=18-14
2y=4
y=4÷2
y=2
80 1.5 because 10 times 8 equals 80 plus 1.5 equals 80.1.5
Answer:
Step-by-step explanation:
Triangle CDE is a right angle triangle.
From the given right angle triangle
CE represents the hypotenuse of the right angle triangle.
With ∠C as the reference angle,
CD represents the adjacent side of the right angle triangle.
DE represents the opposite side of the right angle triangle.
To determineTan C, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan C = 80/39
Tan C = 2.0513
Rounding up to the nearest hundredth, it becomes
2.05
