Answer:
45 = (45+18)
55 = (55+y)
55+y= (63 ×55) /45
y= 77- 55
y = 22 cm
45 = 63
x = 70
x= (45×70)/63
x = 50 cm
The answer is 45 like the other person said

Answer:
1/3
Step-by-step explanation:
if all the boys drank out of the jug than the fraction would be 1/3
1/3+1/3+1/3=1
<L = 1/2(130 - arc MK)
45 = 1/2(130 - arc MK)
90 = 130 - arc MK
arc MK = 130 - 90
arc MK = 40
Answer
arc MK = 40°
Answer:
62,500 pi
Step-by-step explanation:
diameter = radius + radius
d = 2r
r = d/2
A = 4pi r^2
= 4 pi (d/2)^2
= 4pi d^2/4
= 4pi* 250^2/4
= 4pi * 62,500/4
= 4pi * 15625
= 62,500 pi
If you want it in a decimal form it is 8.8
In fraction form it is 44/5, or 8 and 4/5
Area of a full circle is PI x r^2
Area = 3.14 x 8^2 = 200.96
Area of a sector is area * central angle / full circle
Area = 200.96 x 5PI/3 / 2PI = 160PI/3
Answer is C.
