First, let's start with the whole number.
Half of 5 is 2.5 or 2 1/2.
4/5 translated into a decimal is 0.8, so half of that would be 0.4.
0.4 translated into a fraction is 2/5.
Add 2 1/2 to 2/5.
I'll show you the long way and the easier way.
The long way is that you find a common denominator for both fractions.
A common denominator would be 10, because you would multiply 2 and 5 (the denominators).
So this would translate the problem into 2 5/10 (Remember that whatever you do to the bottom you have to do to the top) and 4/10.
If you add these together you get 2 9/10.
The easy ways is taking the decimals in the problem (2.5 and 0.8)
Half of 0.8 is 0.4 (As mentioned above).
2.5 + 0.4.
This equals 2.9.
Answer:3
Step-by-step explanation:
The height of the building is 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- Angle of elevation = 4. 72 degrees
- hypotenuse side = 36 feet tall
- Building height is the opposite side
Using the sine identity:
sin θ = opposite/hypotenuse
Substitute the values
sin 4. 72 = x/ 36
cross multiply
x = sin 4. 72 × 36
x = 0. 0822 × 36
x = 3 feet
Thus, the height of the building is 3 feet
