1/2x1/9=1/18+2=2 1/18 <---- Answer
1/18+34/18=35/18
35/18=2 1/18
This was done in my head so if it is wrong please do not be mad at me :)
Answer: Choice B
95 - 1080n for any integer n
=================================================
Explanation:
Notice how 1080 is a multiple of 360 since 360*3 = 1080. The other values 1450, 780 and 340 are not multiples of 360. For example 1450/360 = 4.02777 approximately. We need a whole number result to show it is a multiple.
Therefore, choice B shows subtracting off a multiple of 360 from the original angle 95. In my opinion, it would be better to write 95+360n or 95-360n to make it more clear we are adding or subtracting multiples of 360.
Choice B will find coterminal angles, but there will be missing gaps. One missing coterminal angle is 95-360 = -265 degrees. So again, 95-360n is a more complete picture. I can see what your teacher is going for though.
It would be 7.45 since the -3.05 and the -9.5 together would equal -12.55 which subtracted from 20 would equal 7.45
Volume a square pyramid is expressed as the one third of the product of the base area and the hight of the shape.
Volume = (1/3)*(base area)* height
Substituting the given values, we have:
(1/3)*(2 * 2) * h = 8
h = 8*3 / (2 * 2)
h = 6 ft
Therefore, the correct answer among the choices is option A.
