642.2 is the answer if you multiply 3.8x169
Answer:
because a triangle has 3 sides and has 3 angles
so each angle on a equilateral triangle has 60 degrees which means
60 x 3 = 180
Step-by-step explanation:
because a triangle has 3 sides and has 3 angles
so each angle on a equilateral triangle has 60 degrees which means
60 x 3 = 180
Is this a genuine question? If so, you would calculate how long it would take for you to reach your destination based on the speed limit. If the speed limit is 40 mph and you need to drive 100 miles, divide the distance by the speed and you find it would take you 2.5 hours. If you speed and go, let’s say 50 mph, divide 100 miles by 50 mph and you will find that it will take 2 hours, saving half an hour of time. Use this strategy to find out how much time you save.
The lateral area of a cone is 147ft².
The total surface area of the cylinder is 867ft².
The total surface area is 1014ft²
<h3>What is the lateral surface area of a cone?</h3>
The lateral area of a cone is defined as the area covered by the curved surface of the cone.
Lateral area of a cone = πr x √(r² + h²)
Where:
- r = radius = 12/2 = 6ft
- h = height = 5ft
- π = 3.14
3.14 x 6 x √(36 + 25) = 147ft²
<h3>What is the total surface area of the figure ?</h3>
Total surface area of the cylinder : πr(r + 2h),
(3.14 x 6) x (6 + 40) = 867ft²
Total surface area = 867 + 147= 1014ft²

If it looks like this
y = 161*(0.725)^t then it's a decay. Reason: the base is under 1. Try a couple of values for t say 0,1,2
y = 161 * (0.725)^0
y = 161
y = 161 * (0.725)^1
y = 161 * 0.725
y = 116.7
y = 161 * (0.725)^2
y = 161 * (0.5256
y = 84.63
You can see that the function is steadily getting smaller. Remember if the base is under 1 and more than 0 the function decays. If it is greater than 1 then the function grows.
Just to make sure we understand what I'm saying
0 < base < 1
y = a ( base)^power.
