Answer:
here
Step-by-step explanation:
100% = 1
14.5 = 14 1/2 = 29/2
14 1/2 = 1450%
14.5% = .68
.68 = 68/100 = 34/50 = 17/25
17/25 =/= 29/2
Answer:
x = 25.7
Step-by-step explanation:
We know the adjacent side to the angle and the hypotenuse on a right triangle
cos theta = adj / hyp
cos 18 = x/27
27 cos 18 =x
25.67852594=x
Rounding to the nearest tenth
x = 25.7

t = 0 seconds, when the ball first took off, and t = 2, 2 seconds later.
the answer is B your welcome
The mean is the average of the two numbers. It can be calculated by adding the two numbers then dividing the answer by 2.
Therefore:
mean = (987+982) / 2 = 984.5
