Answer: B.) $1,383.53
Step-by-step explanation:
Given: The total number bricks required to make the wall= 830
The speed of crew= 300 bricks/hour
Total hours they take to make the wall=
The cost of labour =$4,000 per eight-hour
⇒The cost of labour for 1 hour =
Now, the cost of wall=
Hence, B is the right answer, the cost of the new wall= $1383.53
Answer:
3m/seconds
Step-by-step explanation:
In this problem we are required to solve for linear speed of the rotating wheel
The linear speed =angular speed x raduis
Given data
Radius r= 50cm
Converting from cm to m
50/100= 0.5m
Angular velocity w= 6rad/s
V=wr
V= 6*0.5m
V=3m/s
The linear speed is 3m/seconds
The answer would be 153.86... First of all let's establish the formula to work out the area if a circle - it's area = pi * (radius * radius)... Then let's substitute the values... So we know that the diameter is 14 inches so that must mean the radius is 7 inches, since the radius is simply half of the diameter... Then we multiply pi (I am using 3.14) with 49 inches (since 7 * 7 = 49)... Then the answer you get is 153.86
Hope this helps!! (≧▽≦)
The answer is 21!! pls mark brainliest
