Answer: 33/4 miles per hour
Step-by-step explanation:
Hi, to answer this question we simple have to divide the distance travelled by the bike (2 3/4) by the time spent (1/3)
Speed rate = distance /time
Replacing with the values given:
S = 2 3/4 ÷ 1/3 = (2x4+3)/4 ÷1/3 =11/4 ÷1/3= 33/4 miles per hour
Feel free to ask for more if needed or if you did not understand something.
The applicable identity is ...
... cos(a)cos(b) = (1/2)(cos(a+b) +cos(a-b))
Let a=36t, b=6t and substitute this into your expression. Then you have ...
... 20cos(36t)cos(6t) = 20·(1/2)(cos(36t+6t) + cos(36t-6t))
... = 10(cos(42t) + cos(30t))
... = 10cos(42t) +10cos(30t)
Answer:
x = (r+d)/c
If all you need is for the x to stand alone, all you must do is get rid of all of the values on its side of its equation. So in the equation cx=r+d, the only value with x is c. To get rid of this, you divide it on both sides of the equation to get x = (r+d)/c.
