Answer:
~24.4%
Step-by-step explanation:
A circle is 360 degrees, we all know this.
The angle representing Techno is 28° While Country has a 60°. Combine this and we get 88° of people total chose country or techno. 88° divided by 360° gives us 0.2444444... With percentages, we move the decimal two places to the right, giving us:

Answer:
A. 0.186524036
Step-by-step explanation:
Cosine 79° 15'
But, 1° = 60'
Thus; 15' = 15/60 = 0.25°
Therefore;
cos 79° 15' = cos 79.25°
Cos 79.25° = 0.186524036
= 0.186524036
Answer:

Step-by-step explanation:
The surface area of a square pyramid is the sum of the area of the squared base + 4 times the area of each triangular face, therefore:

where:
is the area of the base, where
L is the length of the base
is the area of each triangular face, where
h is the height of the face
Substituting,

For the model in this problem,
L = 12
h = 8
Therefore, the surface area here is:
