12. A full turn is 360 degrees. 360 divided by 30 is 12.
Answer:
x = 399 new subscribers
Step-by-step explanation:
Let 420 = 100%
x = 95%
420*95 = 100x
x = 420*95/100
x = 399 new subscribers
Answer:
The relationship is positive.
The model predicts a score of 60.
Not sure what part b is.
Step-by-step explanation:
Since while the money spent on advertising increases while the items sold increases, we have a positive relation between both variables.
By looking at where 30 is on the graph, we can see it lines up with 60,the middle between $40 and $80 on the y axis and so we know this is the cost associated with this value.
-Average acceleration is (v2-v1)/(t2-t1). And we are told that he has constant acceleration of 1.5. Since acceleration is constant, constant=average. So:
a=(v2-v1)/(t2-t1) which in this case is:
(9-2)/t=1.5
7=1.5t
t=14/3 seconds
t= 4 2/3 seconds
Answer:
√30
Step-by-step explanation:
We can find the value of x by using Euclidean theorem
x^2 = 3 × 10
if x^ = 30 then x = √30
