Answer:
It is B, D, E, and F.
Step-by-step explanation:
Answer:
Perimeter = 14 + 2sqrt(17)
Area =28
Step-by-step explanation:
FG = 8 counted
EH = 6 counted
using the pythagorean theorem
height = 4 and the base = 1 in the right triangle
HG^2 = 4^2 + 1 ^2
hg^2 = 16+1
hg^2= 17
hg= sqrt(17)
ef^2 = 4^2 + 1 ^2
ef^2 = 16+1
ef^2= 17
ef=sqrt(17)
Perimeter = EF+FG + GH+HE
sqrt(17)+ 8+ sqrt(17) + 6
14 + 2sqrt(17)
A =1/2 (b1+b2) * h
b1 =EH b2 = FG and h = 4 height that we used in the perimeter
= 1/2 (6+8) * 4
= 1/2 * 14*4
=28

The minute hand takes 5 minutes to make 1/6 of half a rotation.
To determine the number of minutes it takes for a hand to make 1/6 of half a rotation, we first need to understand how many degrees are in a complete rotation. A complete rotation is 360 degrees. Half of this is 180 degrees. Therefore, to find 1/6 of half a rotation, we divide 180 by 6, which gives us 30 degrees.
Now we know that the hand moves 30 degrees. In one revolution (or 360 degrees), the minute hand takes 60 minutes. Therefore, to find the number of minutes it takes to move 30 degrees, we set up a proportion:
360 degrees / 60 minutes = 30 degrees / x minutes
Cross-multiplying, we get:
360x = 30 * 60
360x = 1800
x = 1800 / 360
x = 5
So, it takes 5 minutes for the hand to make 1/6 of half a rotation.
