Well depending on which 9 you are talking about it is either 4,930 or 5,000 hope this helped! :)
Answer : the answer to 6.403 divided by 8 is 0.8
Answer:
x=7
Step-by-step explanation:
The two angles are alternate interior angles. If they lines are parallel, then the angles are equal.
7x-7 = 4x+14
Subtract 4x from each side
7x-4x -7 = 4x-4x+14
3x-7 = 14
Add 7 to each side
3x-7+7 = 14+7
3x=21
Divide by 3
3x/3 =21/3
x=7
Answer:
y= 4 1/4
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
y=17/4
Decimal Form:
y=4.25
Mixed Number Form:
y=4 1/4
Answer:
Step-by-step explanation:
Required to prove that:
Sin θ(Sec θ + Cosec θ)= tan θ+1
Steps:
Recall sec θ= 1/cos θ and cosec θ=1/sin θ
Substitution into the Left Hand Side gives:
Sin θ(Sec θ + Cosec θ)
= Sin θ(1/cos θ + 1/sinθ )
Expanding the Brackets
=sinθ/cos θ + sinθ/sinθ
=tanθ+1 which is the Right Hand Side as required.
Note that from trigonometry sinθ/cosθ = tan θ
