CosOsinO - 0.5 cosO = 0
cosO(sinO - 0.5) = 0
so cosO = 0 , sin O = 0.5
cosO = 0 gives O = pi/2 , 3pi/2
sinO = 0.5 gives O = pi/6, 5pi/6.
Answer:
D)5/11
Step-by-step explanation:
So yeah there's 22 balls in total!
Then for the red balls, there are the balls numbered evenly: 6, 8, 10, 12, 14. So there's 5 even balls for red.
Then for the green balls: 8, 10, 12, 14, 16, there are also 5!
5+5=10
10/22
=5/11
The answer is D!
Hoped I helped (P.S. I love math)
Answer:
The answer would be 9
Step-by-step explanation:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$30=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore, 30% of 30 is 9
Answer:
convert 2/5 to a decimal, which is 0.4
multiplying a value by 10 means you should move the decimal point one unit to the right
so 10 x 2/5 = 4
