Answer:
<em>A. 21°, 69°</em>
Step-by-step explanation:
If you work by process of elimination all you have to do is take 27 away from the bigger degree of the two and see if it is 2x as much as the smaller degree.
Ex.
1. 69°-27°= 42°, which is 2x as many as 21°.
Answer: The required probability is 0.3296.
Step-by-step explanation:
Since we have given that
Number of songs = 105
Number of songs are by the Beatles = 10
So, Number of songs are not by the Beatles = 105-10=95
So, the probability that the first Beatles song heard is the fifth song played is given by

Hence, the required probability is 0.3296.
Answer: 3
Step-by-step explanation:
You can answer this question by using the equation
(8+x)(7+x)=110
The x represents the width, as we do not know the area. If you simplify the equation, it becomes 56+15x+x2=110.
If you move all the terms to the left side, and rearrange it, it can become x^2+15x-54=0
This can be simplified into (x-3)(x+18)=0
This equation makes it so that x is either 3 or -18. It is not possible for a width to be -18, so the width must be 3.
