Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
Answer:
15092cm^3
Step-by-step explanation:
The total thickness of the strip of metal sheet would be 2*10=20cm
the new radius of the cylinder would be 9/2+20=24.5cm
Volume of a cylinder: ((pi)r^2)h
the height is 8cm
Volume : (22/7)*24.5^2*8
=15092cm^3
Speed=15 m/s
1 hour=60 minutes
60 minutes=60 minutes (60 seconds/1 minute)=3600 seconds.
15 m/s=(15 m/s)(1 mile / 1609 m)(3600 s/1h)=33.56... miles/hour≈
≈33.6 miles/hour.
Answer: the speed in miles per hour would be 33.6 miles/hour
Answer:
20) the answer is -43
21) the answer is 25
22)the answer is -5
Step-by-step explanation:
20) 
n=-7
p=-6
we have:
21) mp-(p-(m-n))
m= -1 n=-6 p=-10
-1*-10-(-10-(-1-(-6)))
10-(-10-(5))
10-(-15)
10+15=25
22) 
m=1 n=5
1- 
1- 2/2 -5
1-1-5 =-5
