Answer:
36%
Step-by-step explanation:
9/25
multiply each by 4 to get 36/100
as a percent it would be 36%
Answer:
12.5 hours
Step-by-step explanation:
The data which represents the battery life, in hours, experienced by six users is given below:
10 14 14 16 13 8
To determine the point estimate for the web browsing battery life of the iPad, we find the mean number of hours.
The point estimate for the web browsing battery life of the iPad is: 12.5 hours
(x-4)(x-3) so what you do is
x -4
x x^2 -4x
-3 -3x 12
x^2-7x+12
your answer would be -7x
81^2 = 18 ^2 + 80^
6561 = 324 + 6400
6561 = 6724
<span>It is not a right angle, since 18^2 + 80^2 does not equal 81^2.
So,
Using </span><span>The law of cosines:
</span>The largest angle C is opposite to the side c.
Therefore,
<span>c^2 = a^2 + b^2 -2ab cosC </span>
<span>Here,
c^2 < (a^2 + b^2)
cosC must be positive which makes C an acute angle.</span>
