Solution:
As, we have to find ,
% of 20

If we have to Percent of a certain number it means , divide that number by 100 , for example x% means
.
And if i am writing , x% of y it means ,
.
10,080,000 (because 720×14, the total number of days he swam in two weeks, is 10,080 and then you divide it by .001, the number of kilometers in one meter, which gives you 10,080,00.)
bbygirl where the question
Answer:
B. 74
Step-by-step explanation:
The surface area is just the area of the two triangular bases plus the area of the three rectangular sides.
Area of a triangle = (1/2)bh, where b is the base and h is the height. Here, b = 4 and h = 3.5. So: (1/2) * 4 * 3.5 = 7. However, we have two triangles, so we multiply 7 by 2: 7 * 2 = 14.
Area of a rectangle = bh, where b is the base and h is the height. Here, b = 5 and h = 4. So: 5 * 4 = 20. However, there are three rectangles, so we multiply 20 by 3: 20 * 3 = 60.
Now, we just add these together: 14 + 60 = 74.
Thus, the answer is B.
Hope this helps!
