Answer:
Correct choice is D
Step-by-step explanation:
Consider regular 60 sided polygon (regular means all sides are of equal length). Connect the center of this polygon with each polygon's vertex. You get 60 equal isosceles triangles with base that is polygon's side. The measure of the angle opposite to the base is
Rotating the polygon by 6° over the center, each such triangle will map onto the previous triangle. Thus, the least angle by which a regular 60-gon can be rotated so that it maps onto itself is 6°.
Answer:
6.4
Step-by-step explanation:
16 ÷ 2/5 = 6.4!
that's it
You first have to know what par is, or at least if you do it will help, and par is the predetermined number of strokes it takes to hit the ball in the hole. That means you have to swing 6 times to get it in the hole. When a golfer has a -4 that means they took 4 less shots than predetermined and a + 2 means 2 more shots than predetermined. So in the case, Vijay Singh's score of -4 would be less than Phil Mickelson's score of -2, -4 < -2. And in order of least to greatest it would be Vijay Singh, Phil Mickelson, Tiger Woods, Justin Leonard.
Btw I had to look up all the golf stuff. I know nothing about golf.
Answer:
30in squared
Step-by-step explanation:
(4x5) + ((4x3)/2) + ((4x2)/2) = 20 in sq.
Answer:
<h2> 55.10min </h2>
Step-by-step explanation:
This problem is on the mensuration of flat shapes.
given that the initial radius before Cody alerted the fire department is
10 ft
Then we can calculate the area of the fire as
Area= πr^2
Area=3.142*(10)^2
Area=3.142*100
Area=314.2ft^2
Also, given that the area of the circular fire has grown to 45401 square feet
let us solve for the radius first, then we can calculate the time taken since the radius was increasing by 2 ft/min
let the radius of the large fire be R
45401=πR^2
R^2=45401/3.142
R^2=14449.714
square both sides we have
R=√14449.714
R=120.2ft
The difference between the radius of the initial fire and the large fire is
R-r=120.2-10
=110.2ft
Hence the time taken can be calculated as
time= 110.2/2
time=55.10min
