I believe the correct answer from the choices listed above is the last option. THe missing step of her solution would be the statement "<span>Divide both sides of the equation by 10.4." Hope this answers the question. Have a nice day.</span>
If you are working out the number of KM per CM them you divide the KM by the CM:
15/0.75 = 20
This means that it is 20KM per every 1CM
Hope this helps! :)
Answer:
A
Step-by-step explanation:
Deshaun charges $40 per hour.
So if Deshaun and Silvio work for 5 hours, then it would be $40(5) which would be more expensive than Silvio's with $60 + 20(5). Silvio gets $60 with $20 per hour.
Deshaun would get $200 while Silvio would get $160.
Here's the sum rule for the tangent function:
In the special case a=b, this becomes the double angle formula:
In your case, you case use the sum rule once:
And use it again, in the special case of the double angle:
We can obvisouly simplify this expression a lot: let's deal with the numerator and denominator separately: the numerator is
and the denominator is
So, the fraction is
Answer:
250
Step-by-step explanation:
40% = 100
100 x 2 = 200 and 80%
40/2 = 20%
100/2 = 50
20% + 80% = 100%
50 + 200 = 250
