Answer:
0=2pi/3 or another way of writing I is 0= 120°+360°×n
Simplify brackets
16/20 = t + -13/20
Simplify 16/20 to 4/5
5/5 = t - 13/20
Add 13/20 to both sides
4/5 + 13/20 = t
Simplify 4/5 + 13/20 to 29/20
29/20 = t
Switch sides
<u>t = 29/20</u>
60 seconds per minute, 60 minutes per hour
60*60 = 3600 seconds per hour
5280 feet per mile
300/5280 = 0.0568 of a mile
2.92/3600 = 0.000811 of an hour
0.0568 / 0.000811 = 70.028 miles per hour
round to 70 miles per hour

Answer:
48 sq. in.
Step-by-step explanation:
Different figures (rectangular prisms, cylinders, triangular prisms etc.) have different volume formula. But what formula of "volume" do they come from??
It is:
Volume = Area of Base * Height
<u>Note:</u> we didn't specify any Area of Base formula because it depends. If base is circle, the area is different than if base was suppose a square. But this is the general formula of volume.
Now,
Given
Height = 18 inch
Volume = 864 cubic inch
We can write:
Volume = Area of Base * Height
864 = Area of Base * 18
Thus,
Area of Base = 864/18 = <u>48 sq. in.</u>
<u>This is what we are wanting, "area of base" (irrespective of the shape).</u>
