Answer:
960.7 ft
Step-by-step explanation:
A right triangle is formed where the distance between Jack and the base of the building is one of the triangles legs and the height of the building plus 5 feet is the other leg (let's call it x). The included angle between the hypotenuse and the distance between Jack and the base of the building is 67°. From definition:
tan(α) = opposite/adjacent
tan(67) = x/400
x = tan(67)*400
x = 965.7 ft
Then, the height of the building is 965.7 ft - 5 ft = 960.7 ft
Answer:
Attached
Step-by-step explanation:
This is a poorly described problem because books are different lengths meaning they possess different number of pages.
With that being said let's assume all books have exactly the same number of pages.
The formula to calculate how many books can he read in 12 days it's obvious:
which is
and then
. Hope this helps!
Answer:
it's 9.947
Step-by-step explanation:
for this we need an equation which contain height in it so we used volume in both so we get height
π2^2h=5*5*5
π4h=125
h=9.947
