21/7=3mins per wall with 5 people.
Because we assume that all of the people paint at the same rate, 3 X 5=15 mins for one person working alone.
15/3=5 mins per wall with 3 people X 10 people= 50 mins for 3 people to paint 10 walls.


The answer is 50 mins.

Determine the angular velocity, in radians per second, of 14.2 revolutions in 8 seconds
adoni [48]
To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
            
                        n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
                          n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.

TiliK225 [7]
She is expected to pay $4508 up front.

Application fee:  2% of 1300 = 0.02(1300) = 26
Credit application fee:  10
Security deposit:  1300
Last month's rent:  1300
Broker fee:  12% of year's rent = 0.12(1300)(12) = 1872

26+10+1300+1300+1872 = 4508

the function f(h)=2d+4.3 relates the h height of the water in a function on a calculator and use the graph to find the height of
Gemiola [76]
So, if "d" equals the diameter, we need to plug in 1.5 for "d". The equation now looks like: f(h) = 2(1.5) +4.3. Now if you multiply, it's: f(h) = 3 + 4.3, which then is: f(h) = 7.3. The height would be 7.3 in, when the diameter is 1.5 in. Hope this helps =). Have a great day!
