Answer: 3082.2
Step-by-step explanation:
Answer:
The diameter of the semicircle is 7 inch.
Step-by-step explanation:
So, diameter of the semicircle is 7 inch, whose radius is 7 inch. Therefore area of semicircle is 113.04 inch 2, whose diameter is 24 inch. So, circumference of semicircle is 21.98, whose radius is equal to 7 inch. So, arc length of a semi circle is 3.64 inch, whose radius is 7 inches and central angle is 60 degree.
1/2 I think. Even though you already got heads 10 times you still have a 1/2 chance to get it again.
Answer:
w=5 x=2.1 y=5.4 z= 14.1
Step-by-step explanation:
w² = 13² - 12² = 25
w = 5
cos ∠1 = 12/13 = 13/(12+x)
12 (12+x) = 13 x 13 = 169
144 + 12x = 169
12x = 25
x = 25/12 = 2.08 = 2.1
∠1 + ∠2 = 90°
∠2 + ∠4= 90° ∠4 = ∠1
sin ∠4 = x/y = sin ∠1 = 5/13
5y = 13x
y = 13/5 x = 13/5 * 25/12 = 65/12 = 5.4
z = 12 + x = 12 + 2.08 = 14.08 = 14.1
Yes, becasue of reciprocation you might end up with a number above 1.
