Answer:

2,340

Step-by-step explanation:

<u><em>Using Formula</em></u>

=> (n-2)*180

<u><em>Where n is the number of sides. Here, no. of sides is 15</em></u>

=> (15-2)*180

=> 13*180

=> 2,340

Answer:

2340°

Step-by-step explanation:

To find the sum of interior angles of any shape, use the formula: 180(n - 2), where <em>n</em> is how many sides there are. <em>So</em>,

180(15 - 2)

180(13)

2340

Two pools are being filled with water. To start, the first pool contains 2200
Lynna [10]

2200 + 21.25X = 1840 +32.50X

subtract 1840 from each side

360+ 21.25X= 32.50X

subtract 21.25x from each side

360=11.25X

x= 360/11.25 = 32 minutes pool will have the same amount

 

21.25*32 = 680+2200 = 2880 liters

32.5*32 = 1040 + 1840=2880 liters

 

 it will take 32 minutes and they will have 2880 liters each

A body and tackle with a velocity ratio of 5 is used to raise a mass of 50kg through a vertical distance of 20n at a steady rate
matrenka [14]

a. Distance moved by effort = 1 meter

b. Work done by effort = 80 Joules

c. Losses in energy = 18 Joules

<h3>How to determine the parameters</h3>

a. Note that velocity ratio is defined as the ratio of a distance through which any part of a machine moves to the distance moved by its parts

Velocity ratio = distance moved by the effort/distance moved by the body

Where velocity ratio = 5

vertical distance = 20cm

Distance moved by effort = 5 × 0. 20 = 1 meter

b. Formula for work done is given as ;

Work done = Effort × distance moved by effort

Work done = 80 × 1

Work done = 80 Newtons

c. First, let's find the work output

Work output = m g h

Work output = 50 × 9.8 × 0. 20

Work output = 98 Joules

Losses in energy = Work output - work done

Losses in energy = 98 - 80

Losses in energy = 18 Joules

Solve by completing the square: 5x2 + 20x + 32 = 0
igor_vitrenko [27]
Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it
