Answer:
1.25 inspections in an hour
Step-by-step explanation:
10/8= 1.25
Answer:
x = 35 , y = 72.5
Step-by-step explanation:
(a)
x and 35° are vertical angles and are congruent, then
x = 35
(b)
y. y and 35 lie on a straight line and sum to 180°, that is
y + y + 35 = 180
2y + 35 = 180 ( subtract 35 from both sides )
2y = 145 ( divide both sides by 2 )
y = 72.5
Recognize that both 0.96 and 0.144 are divisible by 12:
(0.96/12) / (0.144/12) = 0.08 / 0.012. This reduces to 0.02 / 0.003, or
20/3 or approx. 6.666.
You could also begin by eliminating the decimal fractions. Mult. 0.96 and 0.144 each by 1000 results in 960/144.
Since both 960 and 144 can be divided evenly by 24, we get 40 and 6.
40/6 = 20/3, or approx. 6.666, as before.
(x-center)^2+(y-center)^2=r^2
x^2+y^2=r^2
(5)^2+(-12)^2=r^2
25+144=r^2
169=r^2
r=13
Answer:
107.94 inches
Step-by-step explanation:
Circumference = 2 pi r = 6.28 *31 = 194.28
1% arc = 3.6 = 1.9428
55.56% of 360=200.016
55.56% of 194.28 =107.94
You can try using this guide to apply to arc segments
The radius is 31inch if it was a prime factor of 360 then you could use the equation arc = radius / no of segments
Ifthe circle had 30 inch radius then 360/30 = 12
Then divide by the 200/30 = 6.66
The circumference then would be similar 114.44inch
