What i did is that i did $1.50 time 8 = $12.00 and then do $30.00-12.00=$18.00
20/2.5 = 8
So 8 movies can be shown in 20 hours.
You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
<span>P(t)=P₀a^t
</span>P(t)=6 billion * 101.9%^50= 6 billion * <span>2.56276= 15.38 billion</span><span>

Answer:
The area of a label is ![62.8\ in^{2}](https://tex.z-dn.net/?f=62.8%5C%20in%5E%7B2%7D)
Step-by-step explanation:
we know that
The lateral area of a cylinder (label of the can) is equal to
![LA=2\pi rh](https://tex.z-dn.net/?f=LA%3D2%5Cpi%20rh)
we have that
A can is 4 inches wide
so
The diameter of the can is 4 inches
----> the radius is half the diameter
----> height of the label
substitute in the formula
![LA=2(3.14)(2)(5)=62.8\ in^{2}](https://tex.z-dn.net/?f=LA%3D2%283.14%29%282%29%285%29%3D62.8%5C%20in%5E%7B2%7D)
Answer:
4000 ![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
Step-by-step explanation:
V = 1/3(Bh) where B is the area of the base and h is the height of the pyramid
B = 20(20) = 400 h = 30
V = 1/3(400)(30) = 4000 ![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
