Answer:
4 11/20
Step-by-step explanation:
Using bidMAs Multiplication comes first before addition
2/5 * 7/6 = 14/30
7/6 * 7/2 = 49/12
Make denominators equal
14/30 * 2 = 28/60
49/12 * 5 = 245/60
Then add
28/60 + 245/60 = 273/60
Finally convert improper into mixed fraction
4 11/20
there are 36 inches in a yard
Y is being multiplied by 0.6 so you have to divide by 0.6 on both sides to leave y alone.
y=10.3/0.6
Answer:
Step-by-step explanation:
Required man days to complete the job = 8 * 6
= 48 Man Days
Required labors to complete the job by 15 days = 48/15
= 3.2
It means, it is required 4 labors can complete the certain work by 15 days
The identity Sin(α)/Tan(α) = Cos(α) is valid
Trigonometry is study of triangles. All trigonometric ratios are defined using the sides of the right triangle, such as an adjacent side, opposite side, and hypotenuse side. Three major of them are as follows :-
Sine Function:
sin(θ) = Opposite / Hypotenuse
Cosine Function:
cos(θ) = Adjacent / Hypotenuse
Tangent Function:
tan(θ) = Opposite / Adjacent
Lets prove this identity by proceeding with the LHS
= Sin(α)/Tan(α)
= Sin(α)/ (Sin(α)/Cos(α)) (Tan(α) = Sin(α)/Cos(α))
= Sin(α)xCos(α) / Sin(α)
= Cos(α)
Hence verified
