3/8 for black and 2/8 for white since there are a total of 8 sections you take the amount of each color section and put it over the number of total sections.
Answer:
72
Step-by-step explanation:
A person can read 24 pages in 1/3 hour. There are 3 * 1/3 hours in 1 hour.
So, the person can read 24 * 3 = 72 pages in one hour.

Answer:
question (1)
height of building = 308 ft
question (2)
cos 67.11 = 7/18
Explanation:
question (1)
Taking a look at the triangle, we can see that it is a right-angled triangle. This means that we can apply the special trigonometric identities.
The one we will use here is:
tan Θ = opposite / adjacent
where:
Θ = 72
the opposite side is the height of the building
the adjacent side = 100 ft
Substitute to get the height as follows:
tan(72) = height / 100
height = tan(72)*100 = 307.76 which is approximately 308 ft
question (2):
We are given that:
cos Θ = 7/18
therefore:
Θ = cos^-1(7/18)
Θ = 67.114
approximating to the nearest tenth, we would find that:
Θ = 67.11°
Hope this helps :)
