We can move the values of "n" and the numbers to their own sides:
22 = 8 + 2n
-2n = 8 - 22
-2n = -14
2n = 14
n = 7
3 out of 10 or 30% becasue if he is guessing and he has to get 7 out of 10 right then it would be 3 out of 10
Answer:
You calculate the distance between the angle and the arch and you can solve your answer.
Step-by-step explanation:
For example... An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π radians = 180° π r a d I a n s = 180 ° .
Answer: step 3
I just took the test and got a 100%
A) You just fill in 0 for w in the problem and anything raised to the power of 0 is 1, so 230(1) is 230, and that is the old factory and at 0 for the new it is at 190. Subtract then explain why you did what you did.
B) I believe what they are asking for you to do, is you can take each week from the new factory and subtract it and find the equation for the new factory, you already know the growth rate for the old factory= 230(1.1)^w.
C) You take your old factory's equation and plug in numbers until one of them is greater at the new factory. Here it is the 5th week.
