Answer:
Any angle that is on the inside of a shape is called an interior angle.
Step-by-step explanation:
Any angle that is on the outside of a shape is called an exterior angle. An exterior angle is made by extending one of the lines of the shape beyond the intersection point. ... Notice that the two angles make a straight line.
2=1.04^t
t=ln2/(ln1.04)
t=17.673 (approx)
so t=18 (although you will have slightly more than double)
An architect is trying to build a cover for two cylinders. He knows the radius of Cylinder 1 is 15 inches and the radius of Cylinder 2 is 16 inches. What is the area of both circles?
The answer is not a whole number depending on what the question allows as an answer it could be 6 remainder 6 or 6.4 as a decimal.
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together
multiply thru by 130x:-
10 x+ 13 x = 130
x = 130/23 = 5.65 hours or about 6 hours 39 minutes
